August, 2022 This notice applies to your vehicle, VIN: Inspect Brake Booster NHTSA Recall ID: 22V315 MBUSA ID: 2022050014 & 2022050015 Reminder Notification STOP DRIVE ORDER! Dear Mercedes-Benz Owner: STOP DRIVE – Your vehicle can be towed to an authorized dealer and a mobility solution provided or a mobile repair may be possible • An Inspection procedure is available • Schedule an appointment with your authorized Mercedes-Benz dealership as soon aspossible. • This repair will be provided FREE of charge. This notice is being sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has decided that a defect which relates to motor vehicle safety exists in certain Model Year (“MY”) 2006-2011 ML-Class and MY2006-2012 GL-Class and R-Class vehicles. Our records indicate that your vehicle is included in the affected population of vehicles. The original communication for this recall was sent to the owner who was on file as of June 2022. What is the issue? Moisture may accumulate and cause corrosion in the brake booster housing unit, which can result in reduced brake performance. In some cases of severe corrosion, a particularly strong or hard braking application may cause mechanical damage in the brake booster, which can result in brake failure. In this case, it would not be possible to decelerate the vehicle via the brake pedal. Reduced brake performance or brake failure can increase the risk of a crash or injury. Owners are advised not to drive their vehicles until the inspection is performed. What will your Mercedes-Benz Dealership do? An authorized Mercedes-Benz dealer will inspect the brake booster housing. While the repair time may be less than 1 hour, your dealer can provide you with a better estimate of the overall time for this inspection. After the inspection, your vehicle will fall into one of three categories: Category 1: Vehicles will have an aesthetic rubber sleeve removed to eliminate further risk of corrosion. Vehicles that do not show advanced corrosion may continue to be driven with no further action. Category 2: If, after the rubber sleeve is removed advanced corrosion is present, an additional diagnostic test will be performed to ensure the functionality of the brake booster. If the vehicle passes inspection, it may be driven but must return for an additional test and repair within two years. A certificate will be provided by the performing dealership. When the brake booster parts are available or the vehicle needs to be re-tested, an additional reminder owner notification letter will be mailed. Category 3: Vehicles that do not pass the additional diagnostic test will require a brake booster replacement and the stop drive will remain in effect. At this time, parts are not available for an immediate replacement. When parts are available, an additional owner notification letter will be sent. In the event your vehicle does not pass the diagnostic test, the vehicle may be stored at your residence or be towed to a dealership storage location. If the inspection was performed via mob.ile service and you choose to have the vehicle towed to a storage location, please contact the dealership to initiate the tow. If the dealership is unable to assist, please call 1-888-548-8514 to arrange a tow. In the event a brake booster repair is necessary, your authorized Mercedes-Benz dealer will help coordinate an individualized mobility solution since replacement parts are not available at this time. This service will be provided free of charge. How do I schedule an inspection? MBUSA strongly encourages you to schedule a mobile inspection with your local dealer. In the event a mobile inspection cannot be performed, a tow to your nearest authorized Mercedes-Benz dealership will be provided free of charge. To locate authorized dealers see www.MBUSA.com/recall. Please mention you are scheduling an appointment to inspect the brake booster housing under Recall Campaign #2022050014 or 2022050015. You may be asked for your 17-digit Vehicle Identification Number (VIN) which for your convenience is located above your name at the top of this letter. I need alternate transportation, what are my options? When available, a dealer may be able to provide a loaner vehicle. If no loaner vehicles are available, other solutions may be offered such as taxi/rideshare, public transportation cost reimbursement, and/or rental reimbursement. Please discuss with your dealer the conditions and availability of each option. Will this affect other brake system components? This recall relates to potential advanced corrosion on the brake booster housing. If other brake system component(s) are in need of repair/replacement such that they would impair or hinder inspecting the brake booster housing, the repair/replacement must be completed first to allow the brake booster housing to be inspected. These parts and labor costs are not covered under this recall and are the responsibility of the owner. I no longer feel safe in my car. What if I no longer want to drive this vehicle? We ensure you that the inspection program has been thoroughly vetted. If you still have concerns please contact our customer service center at 1-888-548-8514.

Production Dates : OCT 21, 2004 – JUL 11, 2012 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : After extended time in the field and in conjunction with significant water exposure, this corrosion might lead to a leakage of the brake booster. In this case, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle and/or to potentially increased stopping distance. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard braking maneuver to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the service brake. Thus, the risk of a crash or injury would be increased. The function of the foot parking brake is not affected by this issue. Description of the Cause : Moisture may wick under a rubber sleeve that is installed around the brake The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22V-315 Page 7 Identification of Any Warning that can Occur : booster housing for aesthetic reasons. This might result in corrosion in the joint area of the brake booster housing. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal.

The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22V-315 Page 8 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will remove the rubber sleeve and inspect the brake booster housing on the affected vehicles. Vehicles that do not exhibit advanced corrosion may continue to be driven with no further action. Vehicles that show advanced corrosion will have an additional test performed to ensure the functionality of the brake booster. Vehicles that pass the additional test may be driven for up to two years but must return for an additional repair. Vehicles that do not pass the additional test will require a brake booster replacement. The stop-drive notice will remain in effect for these vehicles until the brake booster is replaced. In the event a repair is necessary and cannot be carried out immediately, an authorized Mercedes-Benz dealer will help coordinate an individual solution for the customer, including alternate mobility. Pursuant to 49 C.F.R. § 577.11, MBUSA plans to provide notice about pre- notice reimbursement to owners since some of the involved vehicles could have been previously subject to the condition described.

Production Dates : OCT 21, 2004 – JUL 11, 2012 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : After extended time in the field and in conjunction with significant water exposure, this corrosion might lead to a leakage of the brake booster. In this case, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle and/or to potentially increased stopping distance. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard braking maneuver to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the service brake. Thus, the risk of a crash or injury would be increased. The function of the foot parking brake is not affected by this issue. Description of the Cause : Moisture may wick under a rubber sleeve that is installed around the brake The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22V-315 Page 7 Identification of Any Warning that can Occur : booster housing for aesthetic reasons. This might result in corrosion in the joint area of the brake booster housing. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal.

FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : After extended time in the field and in conjunction with significant water exposure, this corrosion might lead to a leakage of the brake booster. In this case, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle and/or to potentially increased stopping distance. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard braking maneuver to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the service brake. Thus, the risk of a crash or injury would be increased. The function of the foot parking brake is not affected by this issue. Description of the Cause : Moisture may wick under a rubber sleeve that is installed around the brake The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22V-315 Page 7 Identification of Any Warning that can Occur : booster housing for aesthetic reasons.

FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : After extended time in the field and in conjunction with significant water exposure, this corrosion might lead to a leakage of the brake booster. In this case, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle and/or to potentially increased stopping distance. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard braking maneuver to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the service brake. Thus, the risk of a crash or injury would be increased. The function of the foot parking brake is not affected by this issue. Description of the Cause : Moisture may wick under a rubber sleeve that is installed around the brake The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22V-315 Page 7 Identification of Any Warning that can Occur : booster housing for aesthetic reasons. This might result in corrosion in the joint area of the brake booster housing.

Vehicles that do not exhibit advanced corrosion may continue to be driven with no further action. Vehicles that show advanced corrosion will have an additional test performed to ensure the functionality of the brake booster. Vehicles that pass the additional test may be driven for up to two years but must return for an additional repair. Vehicles that do not pass the additional test will require a brake booster replacement. The stop-drive notice will remain in effect for these vehicles until the brake booster is replaced. In the event a repair is necessary and cannot be carried out immediately, an authorized Mercedes-Benz dealer will help coordinate an individual solution for the customer, including alternate mobility. Pursuant to 49 C.F.R. § 577.11, MBUSA plans to provide notice about pre- notice reimbursement to owners since some of the involved vehicles could have been previously subject to the condition described.

Production Dates : OCT 21, 2004 – JUL 11, 2012 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : After extended time in the field and in conjunction with significant water exposure, this corrosion might lead to a leakage of the brake booster. In this case, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle and/or to potentially increased stopping distance. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard braking maneuver to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the service brake. Thus, the risk of a crash or injury would be increased. The function of the foot parking brake is not affected by this issue. Description of the Cause : Moisture may wick under a rubber sleeve that is installed around the brake The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22V-315 Page 7 Identification of Any Warning that can Occur : booster housing for aesthetic reasons. This might result in corrosion in the joint area of the brake booster housing. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal.

The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22V-315 Page 8 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will remove the rubber sleeve and inspect the brake booster housing on the affected vehicles. Vehicles that do not exhibit advanced corrosion may continue to be driven with no further action. Vehicles that show advanced corrosion will have an additional test performed to ensure the functionality of the brake booster. Vehicles that pass the additional test may be driven for up to two years but must return for an additional repair. Vehicles that do not pass the additional test will require a brake booster replacement. The stop-drive notice will remain in effect for these vehicles until the brake booster is replaced. In the event a repair is necessary and cannot be carried out immediately, an authorized Mercedes-Benz dealer will help coordinate an individual solution for the customer, including alternate mobility. Pursuant to 49 C.F.R. § 577.11, MBUSA plans to provide notice about pre- notice reimbursement to owners since some of the involved vehicles could have been previously subject to the condition described.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis Process Flow Category 3 Launch Process Flow (October 2022-February 9th, 2023) At the time of Category 3 launch in October 2022, two processes happened in tandem: 1) The dealer needed to close out the inspection campaign. a. This would trigger a new campaign based on the warranty claim operation codes. If operation codes were claimed that matched Category 2, vehicles would be moved to a new “PENDING” campaign once a week due to insufficient parts stock. If the operation codes claimed matched Category 3, once a week vehicles would be moved to a new “OPEN” campaign. b. This process only affected opening new campaigns in VMI and did not have anything to do with parts shipment. 2) The dealer needed to claim the correct warranty operation codes for Category 3. a. Once the operation codes were submitted and paid, if they matched the Category 3 warranty operation codes, a booster and, if necessary, a pedal kit were sent out automatically. This was done to prevent over-ordering during a critical parts shortage. Category 2 & 3 Launch Process Flow (February 10th, 2023-Current) 1) Dealers still need to close the inspection campaigns to have a new campaign opened. This process will remain the same as point 1 from the “Category 3 Launch Process Flow” for the time being. An update to the NCU will be issued when this process is also revoked. 2) Now that parts for Category 2 vehicles are available, point 2 from the “Category 3 Launch Process Flow” above is being revised. Warranty operation codes still need to be claimed correctly, however, parts will no longer be shipped out automatically. The dealer must now order parts per VIN via the parts ordering system. There will be no initial parts push since Category 2 vehicles were allowed to drive up to 2 years prior to replacement. Further details below in the FAQ’s, including how many parts dealers are allowed to order. 3) Important! Inspection claims still need to be submitted correctly with the proper warranty operation codes for Category 1, 2 and 3 vehicles, respectively. Category 2 and 3 vehicles must still have Xentry Diagnosis results uploaded to pXD. Please also see #6 in the FAQs below. 4) FAQ’s below detail any open points dealers may have. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs 1. Are parts available to replace brake boosters? a. Yes, for Category 2 and 3 vehicles. 2. How will I receive the parts necessary to complete the campaign? a. The Category 3 parts procedures are being revoked. The parts system block for boosters and the pedal retrofit kits will be lifted. Dealers must put in a unique VIN and order parts only for that vehicle. Do not use the same VIN to order parts. Note: there are no extra pedal retrofit kits and these do not need to be stocked at dealerships. Order ONLY after it is determined that a vehicle needs the retrofit kit. 3. Will parts be pushed for Category 2 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category 2 vehicles. Parts will no longer automatically be pushed to dealerships. 4. Will parts still be pushed for Category 3 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category -3 vehicles. Parts will no longer automatically be pushed to dealerships. 5. After vehicle inspection, will another campaign open to replace the booster? a. Yes, once the inspection campaign has been closed, a new campaign will open. These new campaigns are opened once a week. If the dealer has deemed a vehicle falls into Category 2 or 3, parts need to be ordered by the dealer and can be replaced even if the campaign isn’t open in VMI yet. The RO can be closed once the new campaign is activated. 6. When I hover over the campaign, it still says Category 3 even though the vehicle was a Category 2. Why? a. This is being addressed, however, campaign functionality is not impaired in any way. 7. Are Xentry inspection results audited for verification? a. Xentry log files may be spot checked to ensure the Xentry inspection procedure was performed correctly. Under NO CIRCUMSTANCES may any dealer skip the inspection or purposely influence the test. Dealers may be audited if parts ordering practices show potential malfeasance. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 8. I would like to order spare parts stock to have on-hand. a. Due to limited availability of stock for Category 2 & 3 vehicles at this time, all orders are to be placed by VIN, for only a quantity of one. Once sufficient stock becomes available, standard ordering practices will resume. 9. How long does the customer have to return their loaner or rental vehicle once the category 3 vehicle is repaired? a. Five (5) days at most. This is to accommodate any out of town customers or if there are extenuating circumstances. For special cases, the dealer should assess the situation and offer feedback since each case will be unique. 10. Are rental vehicles still allowed? a. Rental vehicles are only applicable to two groups of vehicles: i. Vehicles awaiting the initial inspection campaign. Once the vehicle inspection has been completed, the owner of any vehicle with a Category 1 should promptly turn in the rental vehicle. ii. Category 2 & 3 vehicles. With the launch of the booster replacement campaign for Category 3 vehicles in October 2022 and Category 2 vehicles in February 2023, no such owner should be in or require a long-term rental. The only allowable rental for Category 2 & 3 vehicles is for the time between inspection and parts arrival/booster replacement, which will only be a few days at maximum. Dealers are required to promptly order parts for Category 2 & 3 vehicles. 11. Now that the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? a. There should not be any Category 3 customers in rental vehicles, storage, etc… as sufficient parts stock for Category 3 vehicles has been available since October 2022. b. In the event a dealer cannot perform the brake booster replacement immediately, see below damage codes. i. Damage code 99803 01 – Mobile inspection incentive 1. $150 per vehicle 2. Claimed separately and on top of the recall inspection ii. Damage code 99039 01 – Towing 1. Up to $125 per tow if arranged by customer or dealer outside of normal process 2. Invoice must be attached to claim 3. Please use normal CAC tow process whenever possible to alleviate reimbursement iii. Damage code 99046 01 – Vehicle storage 1. $15 per vehicle, per day for dealership onsite storage 2. Up to $56.25 per vehicle, per day for offsite storage 3. Invoice must be attached to claim 4. Submit every 30 days and then a final claim to reconcile Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis iv. Damage code 99047 01 – Active vehicle care during vehicle storage 1. $300 per vehicle, one-time, for the entire period claimed at the end of the storage period (i.e. wash, maintain battery, move to avoid flat spots and brake corrosion, etc.) v. Damage code 99304 01 – Mobility solutions 1. Up to $2,400 for rental vehicle (up to $80/day), loaner ($80/day flat fee), taxi / rideshare services or use of public transportation 2. Dealers are encouraged to use loaner vehicles for customer requests. See sales NCU on changes to the CVP program and alternate mobility options. 3. Rental agreement, loaner agreement and/or invoice(s) must be attached to claim. 12. Is there a simple flowchart to understand all of the campaign numbers? 13. Will I need any additional parts for the brake booster replacement? a. No. The dealer should not need any additional parts. It is always a good idea to check the parts you will be using or removing prior to commencing with the replacement. Items such as brake lines (bulk brake line usage should be followed via WIS), electrical connector housings, and caliper bleed screws are all items to inspect.

The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs will be flagged in VMI as “PENDING” on May 12, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (W164/X164 platform) and R-Class (R251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces Issue What We’re Doing Parts required to decelerate the vehicle, and/or increased stopping distances are possible. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Until the inspection process is completed, affected customers will be instructed by the MBUSA recall owner notification letter to stop driving their vehicles at the time of recall launch. The Inspection procedure is not available at this time.

Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis TO: Mercedes-Benz Dealer Principals, General Managers, Sales Managers, Service Managers, Parts Managers RE: Updated Recall Campaign Launch Notification – FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services STOP DRIVE Inspect Brake Booster without Pedal Rework MY06-12 GL-Class, ML-Class, R-Class (X164, W164, V251 platform) UPDATE: February 14, 2023 News Channel Update | Vehicle Compliance & Analysis Recall Campaign Launch Notification Campaign No. : NHTSA ID Campaign Desc. : 2022050015 22V315 22P4290005 February 14, 2023 Inspect Brake Booster Without Pedal Rework This is to notify you of an update to the Recall Campaign Launch to inspect the brake booster on 278,173 Model Year (“MY”) 2006-2012 GL- Class, ML-Class, and R-Class (X164, W164 and V251 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML-Class, GL-Class (W164/X164 platform) and R-Class (V251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, inspect the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. The remedy is available and can be performed. Vehicles Affected Vehicle Model Year(s) Vehicle Model 2006-2012 GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population Total Vehicles in Dealer Inventory 278,173 0 The vehicles were flagged as “OPEN” and Work Instructions are available in Star TekInfo. Customers are advised not to drive their vehicle until an inspection is performed. Based on the results, vehicles may continue to be driven if the inspection is passed, or must be grounded if the inspection is not passed. A follow-up campaign will be issued for any vehicle that requires a brake booster replacement. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY 06-12 GL-Class, ML-Class, and R- Class vehicles covered by this notification until the vehicle has been inspected and passed, or grounded until parts become available and the remedy performed.

Process Flow Category 3 Launch Process Flow (October 2022-February 9th, 2023) At the time of the Category 3 launch in October 2022, two processes occurred in tandem: 1) The dealer was required to close out campaign 2022050014 or 2022050015 for the inspection. a. This triggered a new campaign based on the warranty claim operation codes. If operation codes were claimed that matched Category 2, those vehicles would be moved into a new “PENDING” campaign on a weekly basis due to insufficient parts availability. If the operation codes claimed matched Category 3, vehicles would be moved to a new “OPEN” campaign, also on a weekly basis. b. This process only affected the opening of new campaigns in VMI and was irrespective of parts’ shipments. 2) The dealer was required to claim the correct warranty operation codes for Category 3. a. Once the operation codes were submitted and paid, if they matched the Category 3 warranty operation codes, a booster and, if necessary, a pedal kit were released automatically. This was done to prevent dealers from over-ordering critical parts quantities. Category 2 & 3 Launch Process Flow (February 10th, 2023-Current) 1) Dealers are still required to close the inspection campaigns for a new campaign to be opened. This process will remain the same as point 1 from the “Category 3 Launch Process Flow” until further notice. An update to the NCU will be issued when this process is also revoked. 2) With parts for Category 2 vehicles now available, point 2 from the “Category 3 Launch Process Flow” above has been revised. Warranty operation codes must still be claimed correctly, however, parts will no longer be released automatically. The dealer must now order parts by VIN via the parts ordering system. There will be no initial parts allocation since Category 2 vehicles could be driven up to 2 years prior to replacement. Further details below in the FAQ’s, including the quantity limit of parts dealers may order. 3) Important! Inspection claims still need to be submitted correctly with the proper warranty operation codes for Category 1, 2 and 3 vehicles, respectively. Category 2 and 3 vehicles still must have Xentry Diagnosis results uploaded to pXD. Please also see #6 in the FAQs below. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs SUMMARY OF RECALL 1. What is the recall about? a. The recall campaign is related to the brake booster housing. Specifically, advanced corrosion may have formed on the housing, which could lead to a vacuum leak and impairment to brake effectiveness. 2. What’s the difference between Campaign 2022050014 and 2022050015. a. The inspection is the same, however, different damage codes apply based on the vehicle population. One population requires a pedal re-work, the other does not. 3. Can I continue to drive the car? a. Your safety is our highest priority. MBUSA advises customers to stop driving the vehicle until the first inspection is performed. Customers were notified by first class mail to schedule an appointment to have the inspection performed by an authorized dealer. 4. Why are other models not included? a. Only ML- (MY2006 – 2011), GL- (MY2007 – 2012), and R- (MY2006 – 2012) Class vehicles are fitted with the affected brake booster utilizing a rubber sleeve. Other models are not fitted with this rubber sleeve. Affected vehicles have been identified within this recall. 5. What types of repairs or replacements part(s) are needed? a. Affected vehicles will be inspected as a first step. After this inspection, the vehicle will be given 1 of 3 statuses. 1. Inspected with no advanced corrosion: The rubber sleeve will be removed. The vehicle can be driven with no further action or customer follow-up required. 2. Inspected with advanced corrosion found: A brake efficacy test will be performed. The dealer will order a brake booster and replace. If the customer requests mobility, there are two options. a. The first is detailed in the “Mobility” and “Reimbursement/Owner Pay” FAQ below via loaners or rental options. The dealer will hold the vehicle until the part arrives and subsequently replace the brake booster. b. The latter option, a passed test ensures the tested brake booster will continue to function properly and the vehicle may be driven up to a maximum duration of 2 years from the test date. The dealer will provide a “Certificate of Passed Initial Diagnostic Brake Test” detailing that the test has passed. The dealer or customer may schedule a replacement at the time of their choosing or a new notice will be provided to the owner at a later date to bring the vehicle to an authorized Mercedes-Benz dealership for replacement of the brake booster. 3. Inspected with advanced corrosion and brake efficacy test does not pass: The vehicle will require the brake booster housing to be replaced. Until then, the vehicle MUST NOT be driven. If the customer requests mobility until such time the booster can be replaced, the dealer can offer solutions as detailed below in the FAQ’s. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 6. Will the dealer repair the vehicle with the same part(s)? a. No. Based on the initial inspection, if a replacement of the brake booster is necessary, the part will be removed and replaced with a new part that does not utilize a rubber sleeve. 7. Will the replacement part(s) fail again? a. No. Provided the recall timelines are followed, the inspections and remedial measures performed by your Mercedes-Benz dealership assure you that the recall condition is remedied. 8. How long will the vehicle need to be in the workshop? a. For your convenience, an authorized Mercedes-Benz dealer will offer mobile inspection at your location of choice. Should you request the vehicle be towed to a workshop, the time for the recall will vary and is dependent on towing availability and dealership schedules. The inspection itself will require 1 hour to complete. Additional time may be needed based on the results of the inspection. Your authorized Mercedes-Benz dealer can provide you with a better estimate of the overall time for this inspection. 9. A vehicle came in with no serial code on the brake booster unit and/or the brake booster is not the same color as in the work instruction pictures. What inspection procedure do I follow? a. Please open a PTSS case for verification of aftermarket booster and further processing. 10. Is there additional guidance other than the Work Instructions? a. There is an AKUBIS video on the intranet Learning Link titled “Brake Booster Inspection and Test” (X0027E-US.TTA). This should be used as a GENERAL PROCESS GUIDELINE ONLY. The work instructions attached to this NCU are the main technical resource for performing the recall inspection. Parts 11. Are parts available to replace brake boosters? a. Yes, for Category 2 and 3 vehicles. 12. How will I receive the parts necessary to complete the campaign? a. The prior Category 3 parts release procedures are being revised. Brake boosters will no longer automatically be released. The parts system block for boosters and the pedal retrofit kits have been lifted. Dealers must enter a unique VIN and order parts specific to that vehicle. A single VIN may not be used to order multiple parts. Note: Additional pedal retrofit kits are not available and are unnecessary to be stocked at dealerships. Order ONLY after it is determined that a vehicle needs the retrofit kit based on the campaign number. 13. Will parts be pushed for Category 2 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category 2 vehicles as of February 10, 2023. Parts will no longer automatically be pushed to dealerships. 14. Will parts still be pushed for Category 3 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category 3 vehicles as of February 10, 2023. Parts will no longer automatically be pushed to dealerships. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 15. After vehicle inspection, will another campaign open to replace the booster? a. Yes, once the inspection campaign has been closed, a new campaign will open. These new campaigns are opened on a weekly basis. If the dealer has determined a vehicle falls into Category 2 or 3, repair parts need to be ordered by the dealer and can be replaced even if the campaign isn’t open in VMI yet. The RO can be closed once the new campaign is activated. MOBILITY 16. Will the dealer provide a loaner vehicle? a. The dealer may offer to provide a loaner based on loaner vehicle availability. If available, the loaner will be provided free of charge. If no loaner vehicles are available, other solutions will be offered such as taxi/rideshare, public transportation cost reimbursement, and rental reimbursement. See the “Reimbursements/Owner Pay” section below for additional information. 17. Are rental vehicles still allowed? a. Rental vehicles are only applicable to two groups of vehicles: i.

Can/should dealers wholesale/sell affected used car vehicles? a. No. MBUSA advises dealers not to sell used vehicles subject to this recall until the inspection and, if necessary, brake booster replacement is completed. 31. While performing the Xentry diagnostic test the technician finds a brake fluid leak, can this be covered under warranty? a. Yes. If while performing the inspection procedure other components fail then this would be claimable on the same line as the recall and considered primary loss. 32. While performing the Xentry diagnostic test, the brake line needed to be repaired. How do I address this? a. Follow AR42.10-P-0020A and utilize flaring kit A000 589 20 99 00 to construct brake lines from bulk stock. 33. If the vehicle fails the Xentry diagnostic pressure test, does the RO need to stay open? a.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 34. The customer wishes to keep driving the vehicle and refuses the repair. How do I handle this situation? a. Customer safety is our top priority at Mercedes-Benz. If the customer insists on driving the vehicle despite the warnings associated with a “stop drive” recall, the following language MUST be added to the Repair Order and initialed by the customer: (Initial Here) ASSUMPTION OF RISK FOR REMOVAL OF VEHICLE. I understand that my vehicle is subject to a “Stop Drive” recall and that continuing to drive my vehicle involves inherent risks and dangers of accidents, property loss or damage, and serious personal injury to me and others, as well as potential financial losses. I have carefully considered the extent of the risks involved, and I voluntarily and freely choose to assume these risks. 35. Is there a point of contact for the dealership, AOM’s, or other field personnel to request technical information or assistance relating specifically to the Xentry diagnostic test? a. The Work Instructions and Xentry diagnostic test have been verified prior to the recall launch. Thoroughly read the instructions, directions, and questions as presented in the Xentry diagnostic brake pressure test steps. If there are still questions after completing the first test, please open a PTSS case for the particular process or direction that is unclear. We do not anticipate any questions relating to the test at this time. 36. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a. Follow the same protocol used at your dealership when a customer refuses services offered. Also, make a notation on the RO that “customer refuses to initial the Assumption of Risk.” A customer signature must be recorded on the RO. 37. Now that the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? a. There should not be any Category 3 customers utilizing rental vehicles, storage, etc… as sufficient parts inventory for Category 3 vehicles has been available since October 2022. b.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 Campaign No. 2022050015, May 2022 Revision F 02/13/2023 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2006-2012 Inspect Brake Booster – without Pedal Rework Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers were mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. Prior to performing this Campaign: • VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly. • Please review the entire Campaign bulletin and follow the repair procedure exactly as described. Approximately 278,173 vehicles are affected. Order No. P-RC-2022050015 This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data Control, and MBUSA-SLP S424HH001, Control of Quality Record 8 Inspect Brake Booster Return information for rubber sleeve and quick test has been removed. Existing problems that would hinder the inspection procedure or any subsequent repairs must first be rectified and are the responsibility of the customer. Any associated costs are not claimable and should not be included with the campaign claim. Any primary loss which is a direct result of performing the XENTRY test should be submitted on the same claim as the campaign reimbursement. Before starting work, there must be no fault message present in the instrument cluster for the brake system. If a fault message is present before starting work, it must be rectified and is the responsibility of the customer. Any associated costs are not claimable and should not be included with the campaign claim. 1. Flow chart with allowable labor operation codes when submitting a warranty claim. P-RC-2022050015 9 Check/test procedure A–visual inspection only 1. Open the hood and check the water drains (marking, figure 1) for correct installation and ability to drain. Only for model 251 Clean and correctly install water drains if necessary. Figure 1 P-RC-2022050015 10 2. Remove the rubber sleeve wrapped around the brake booster (A, figure 2) with a suitable tool (hook and side cutting pliers). If the rubber sleeve is not present, please proceed to check/test procedure A1. The rubber sleeve should be separated above the barcode label on the brake booster as seen in (A, figure 2 and B, figure 4.1). Figure 2 3. Take a photo of the rubber sleeve with the VIN label of the B-pillar (A, figures 3 and 4) and store to a local HDD/computer storage location with the vehicle service file and attach it to the warranty claim in EVA. These pictures serve as documentation of the current condition of the brake booster. Figure 3 Figure 4 P-RC-2022050015 11 4. Check corrosion of the brake booster using the removed rubber sleeve. Use figures 5, 6 and 7 to assess corrosion. Brake booster OK: Multiple point-shaped corrosion marks (figure 5) are permissible. A maximum of one point-shaped corrosion mark with a diameter greater than 15 mm (figures 6 and 7) is permitted. Figure 5 OK Figure 6 OK Figure 7 OK Brake booster not OK: Widespread corrosion marks spanning the rubber sleeve are not permissible. More than one corrosion mark with a diameter greater than 15 mm is not permissible. a. Corrosion measurements Exceeds thresholds-NOK: Carry out check/test procedure B – XENTRY/DAS. b. Corrosion measurements Does not exceed threshold-OK (figure 5, 6 or 7): End measure. (Certificate of Passed Initial Diagnostic Brake Test not required). If the measure is ended, do not re-install a new rubber sleeve. Apply marking with white touch-up paint pen (1, figure 8) to the brake booster checked. Under no circumstances should you treat the brake booster with anti-corrosion agent. The findings from the check/test procedure must be documented on the Repair Order and included in the dealer text in the warranty claim in EVA. P-RC-2022050015 12 Check/test procedure A1 – visual inspection only if no rubber sleeve is present 1. Take a photo of the barcode label (B, figure 8) on the brake booster and store to a local HDD/computer storage location with the vehicle service file and attach to the warranty claim in EVA. Figure 8 1. Check sequence of numbers on the barcode label (C, figure 9). a. If the numeric sequence between numbers 13 and 17 is less than “15126”: Carry out scope of testing B – XENTRY/DAS. b. If the numeric sequence between numbers 13 and 17 is greater than or equal to “15126”: End measure. Figure 9 P-RC-2022050015 13 Check/test procedure B – XENTRY/DAS This step is only to be used if step A or A1 has failed Ensure use of XENTRY Diagnosis version 03/2022 or higher. The current version of all add-ons must be installed. Make sure to follow the operation steps exactly as described in XENTRY Diagnosis. 1. Connect XENTRY Diagnosis. XENTRY must be connected via the cable with VCI/SD Connect. Note regarding vehicles with KeylessGo: Remove KeylessGo start button and perform test with ignition key. Do not perform any unnecessary braking procedures (maximum full-stop braking) before the test. As a rule, the test should be performed nonstop without interruption. In certain conditions, the XENTRY scope of testing can be interrupted while the test is ongoing (e.g. hydraulic system is leaky) (cancellation). In this case, please follow the user guidance in XENTRY/DAS Diagnosis, because notes on the causes will be displayed for you. IMPORTANT: If XENTRY/DAS Diagnosis requests that the brake pedal be withdrawn into the starting position toward the driver, this must be done by means of a powerful foot motion. Check brake booster with XENTRY/DAS. To do this, select the menu item “Main groups – Control units – Chassis – ESP-Electronic Stability Program – Complete list of guided tests – Braking power”. Then follow the user guidance in XENTRY/DAS Diagnosis. Print out the brake force “event log” after the test and store to a local HDD/computer storage location. a.

P-RC-2022050015 16 P-RC-2022050015 Certificate of Passed Initial Diagnostic Brake Test Recall campaign – Inspect Brake Booster Vehicle identification number: Dear Valued Customer: Your vehicle’s brake booster has been inspected by your authorized Mercedes-Benz service facility for corrosion and functionality under MBUSA Recall Campaign number 2022050015 or 2022050014 bearing NHTSA ID# 22V315. The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis TO: Mercedes-Benz Dealer Principals, General Managers, Sales Managers, Service Managers, Parts Managers RE: Updated Recall Campaign Launch Notification – FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services STOP DRIVE Inspect Brake Booster with Pedal Rework MY07-08 GL-Class, ML-Class, R-Class (X164, W164, 251 platform) UPDATE: September 23, 2022 News Channel Update | Vehicle Compliance & Analysis Recall Campaign Launch Notification Campaign No. : NHTSA ID Campaign Desc. : 2022050014 22V315 22P4290006 September 23, 2022 Inspect Brake Booster With Pedal Rework This is to notify you of an update to the Recall Campaign Launch to inspect the brake booster on 14,123 Model Year (“MY”) 2007-2008 GL- Class, ML-Class, and R-Class (X164, W164 and 251 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2007-2008 ML-Class, GL-Class (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. The inspection procedure is available and can be performed. Parts are not available at this time should they be needed. Once parts are available, certain customers will be informed via a second owner notification letter to have a final repair performed. Vehicles Affected Vehicle Model Year(s) Vehicle Model 2007-2008 GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population Total Vehicles in Dealer Inventory 14,123 0 The vehicles will be flagged as “OPEN” and Work Instructions will be available in Star TekInfo. Customers are advised not to drive their vehicle until an inspection is performed. Based on the results, vehicles may continue to be driven if the inspection is passed, or must be grounded if the inspection is not passed. A follow-up campaign will be issued for any vehicle that requires a brake booster replacement. Until such time, a “Pending” campaign will be assigned to these vehicles to ensure vehicle status is reflected in the VIN look-up tools mentioned below. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY 07-08 GL-Class, ML-Class, and R- Class vehicles covered by this notification until the vehicle has been inspected and passed, or grounded until parts become available and the remedy performed.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 Campaign No. 2022050014, May 2022 Revision E 09/23/2022 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2007-2008 Inspect Brake Booster – with Pedal Rework Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2007-2008 ML, GL (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. Prior to performing this Campaign: • VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle.

P-RC-2022050014 18 P-RC-2022050014 Certificate of Passed Initial Diagnostic Brake Test Recall campaign – Inspect Brake Booster Vehicle identification number: Dear Valued Customer: Your vehicle’s brake booster has been inspected by your authorized Mercedes-Benz service facility for corrosion and functionality under MBUSA Recall Campaign number 2022050015 or 2022050014 bearing NHTSA ID# 22V315. The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis TO: Mercedes-Benz Dealer Principals, General Managers, Sales Managers, Service Managers, Parts Managers RE: Updated Recall Campaign Launch Notification – FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services STOP DRIVE Inspect Brake Booster with Pedal Rework MY06-12 GL-Class, ML-Class, R-Class (X164, W164, V251 platform) UPDATE: February 14, 2023 News Channel Update | Vehicle Compliance & Analysis Recall Campaign Launch Notification Campaign No. : NHTSA ID Campaign Desc. : 2022050014 22V315 22P4290006 February 14, 2023 Inspect Brake Booster With Pedal Rework This is to notify you of an update to the Recall Campaign Launch to inspect the brake booster on 14,123 Model Year (“MY”) 2006-2012 GL- Class, ML-Class, and R-Class (X164, W164 and V251 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML-Class, GL-Class (W164/X164 platform) and R-Class (V251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, inspect the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. The remedy is available and can be performed. Vehicles Affected Vehicle Model Year(s) Vehicle Model 2006-2012 GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population Total Vehicles in Dealer Inventory 14,123 0 The vehicles were flagged as “OPEN” and Work Instructions are available in Star TekInfo. Customers are advised not to drive their vehicle until an inspection is performed. Based on the results, vehicles may continue to be driven if the inspection is passed, or must be grounded if the inspection is not passed. A follow-up campaign will be issued for any vehicle that requires a brake booster replacement. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY 06-12 GL-Class, ML-Class, and R- Class vehicles covered by this notification until the vehicle has been inspected and passed, or grounded until parts become available and the remedy performed.

Process Flow Category 3 Launch Process Flow (October 2022-February 9th, 2023) At the time of the Category 3 launch in October 2022, two processes occurred in tandem: 1) The dealer was required to close out campaign 2022050014 or 2022050015 for the inspection. a. This triggered a new campaign based on the warranty claim operation codes. If operation codes were claimed that matched Category 2, those vehicles would be moved into a new “PENDING” campaign on a weekly basis due to insufficient parts availability. If the operation codes claimed matched Category 3, vehicles would be moved to a new “OPEN” campaign, also on a weekly basis. b. This process only affected the opening of new campaigns in VMI and was irrespective of parts’ shipments. 2) The dealer was required to claim the correct warranty operation codes for Category 3. a. Once the operation codes were submitted and paid, if they matched the Category 3 warranty operation codes, a booster and, if necessary, a pedal kit were released automatically. This was done to prevent dealers from over-ordering critical parts quantities. Category 2 & 3 Launch Process Flow (February 10th, 2023-Current) 1) Dealers are still required to close the inspection campaigns for a new campaign to be opened. This process will remain the same as point 1 from the “Category 3 Launch Process Flow” until further notice. An update to the NCU will be issued when this process is also revoked. 2) With parts for Category 2 vehicles now available, point 2 from the “Category 3 Launch Process Flow” above has been revised. Warranty operation codes must still be claimed correctly, however, parts will no longer be released automatically. The dealer must now order parts by VIN via the parts ordering system. There will be no initial parts allocation since Category 2 vehicles could be driven up to 2 years prior to replacement. Further details below in the FAQ’s, including the quantity limit of parts dealers may order. 3) Important! Inspection claims still need to be submitted correctly with the proper warranty operation codes for Category 1, 2 and 3 vehicles, respectively. Category 2 and 3 vehicles still must have Xentry Diagnosis results uploaded to pXD. Please also see #6 in the FAQs below. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs SUMMARY OF RECALL 1. What is the recall about? a. The recall campaign is related to the brake booster housing. Specifically, advanced corrosion may have formed on the housing, which could lead to a vacuum leak and impairment to brake effectiveness. 2. What’s the difference between Campaign 2022050014 and 2022050015. a. The inspection is the same, however, different damage codes apply based on the vehicle population. One population requires a pedal re-work, the other does not. 3. Can I continue to drive the car? a. Your safety is our highest priority. MBUSA advises customers to stop driving the vehicle until the first inspection is performed. Customers were notified by first class mail to schedule an appointment to have the inspection performed by an authorized dealer. 4. Why are other models not included? a. Only ML- (MY2006 – 2011), GL- (MY2007 – 2012), and R- (MY2006 – 2012) Class vehicles are fitted with the affected brake booster utilizing a rubber sleeve. Other models are not fitted with this rubber sleeve. Affected vehicles have been identified within this recall. 5. What types of repairs or replacements part(s) are needed? a. Affected vehicles will be inspected as a first step. After this inspection, the vehicle will be given 1 of 3 statuses. 1. Inspected with no advanced corrosion: The rubber sleeve will be removed. The vehicle can be driven with no further action or customer follow-up required. 2. Inspected with advanced corrosion found: A brake efficacy test will be performed. The dealer will order a brake booster and replace. If the customer requests mobility, there are two options. a. The first is detailed in the “Mobility” and “Reimbursement/Owner Pay” FAQ below via loaners or rental options. The dealer will hold the vehicle until the part arrives and subsequently replace the brake booster. b. The latter option, a passed test ensures the tested brake booster will continue to function properly and the vehicle may be driven up to a maximum duration of 2 years from the test date. The dealer will provide a “Certificate of Passed Initial Diagnostic Brake Test” detailing that the test has passed. The dealer or customer may schedule a replacement at the time of their choosing or a new notice will be provided to the owner at a later date to bring the vehicle to an authorized Mercedes-Benz dealership for replacement of the brake booster. 3. Inspected with advanced corrosion and brake efficacy test does not pass: The vehicle will require the brake booster housing to be replaced. Until then, the vehicle MUST NOT be driven. If the customer requests mobility until such time the booster can be replaced, the dealer can offer solutions as detailed below in the FAQ’s. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 6. Will the dealer repair the vehicle with the same part(s)? a. No. Based on the initial inspection, if a replacement of the brake booster is necessary, the part will be removed and replaced with a new part that does not utilize a rubber sleeve. 7. Will the replacement part(s) fail again? a. No. Provided the recall timelines are followed, the inspections and remedial measures performed by your Mercedes-Benz dealership assure you that the recall condition is remedied. 8. How long will the vehicle need to be in the workshop? a. For your convenience, an authorized Mercedes-Benz dealer will offer mobile inspection at your location of choice. Should you request the vehicle be towed to a workshop, the time for the recall will vary and is dependent on towing availability and dealership schedules. The inspection itself will require 1 hour to complete. Additional time may be needed based on the results of the inspection. Your authorized Mercedes-Benz dealer can provide you with a better estimate of the overall time for this inspection. 9. A vehicle came in with no serial code on the brake booster unit and/or the brake booster is not the same color as in the work instruction pictures. What inspection procedure do I follow? a. Please open a PTSS case for verification of aftermarket booster and further processing. 10. Is there additional guidance other than the Work Instructions? a. There is an AKUBIS video on the intranet Learning Link titled “Brake Booster Inspection and Test” (X0027E-US.TTA). This should be used as a GENERAL PROCESS GUIDELINE ONLY. The work instructions attached to this NCU are the main technical resource for performing the recall inspection. Parts 11. Are parts available to replace brake boosters? a. Yes, for Category 2 and 3 vehicles. 12. How will I receive the parts necessary to complete the campaign? a. The prior Category 3 parts release procedures are being revised. Brake boosters will no longer automatically be released. The parts system block for boosters and the pedal retrofit kits have been lifted. Dealers must enter a unique VIN and order parts specific to that vehicle. A single VIN may not be used to order multiple parts. Note: Additional pedal retrofit kits are not available and are unnecessary to be stocked at dealerships. Order ONLY after it is determined that a vehicle needs the retrofit kit based on the campaign number. 13. Will parts be pushed for Category 2 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category 2 vehicles as of February 10, 2023. Parts will no longer automatically be pushed to dealerships. 14. Will parts still be pushed for Category 3 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category 3 vehicles as of February 10, 2023. Parts will no longer automatically be pushed to dealerships. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 15. After vehicle inspection, will another campaign open to replace the booster? a. Yes, once the inspection campaign has been closed, a new campaign will open. These new campaigns are opened on a weekly basis. If the dealer has determined a vehicle falls into Category 2 or 3, repair parts need to be ordered by the dealer and can be replaced even if the campaign isn’t open in VMI yet. The RO can be closed once the new campaign is activated. MOBILITY 16. Will the dealer provide a loaner vehicle? a. The dealer may offer to provide a loaner based on loaner vehicle availability. If available, the loaner will be provided free of charge. If no loaner vehicles are available, other solutions will be offered such as taxi/rideshare, public transportation cost reimbursement, and rental reimbursement. See the “Reimbursements/Owner Pay” section below for additional information. 17. Are rental vehicles still allowed? a. Rental vehicles are only applicable to two groups of vehicles: i. Vehicles awaiting the initial inspection campaign. Once the vehicle inspection has been completed, the owner of any vehicle with a Category 1 should promptly turn in the rental vehicle. ii. Category 2 & 3 vehicles. With the launch of the booster replacement campaign for Category 3 vehicles in October 2022 and Category 2 vehicles in February 2023, no such owner should be in, or require a long-term rental. The only allowable rental for Category 2 & 3 vehicles is for the time between inspection and parts arrival/booster replacement, which will only be a few days at maximum. Dealers are required to promptly order parts for Category 2 & 3 vehicles. 18. How does the dealer handle rental reimbursements? a. The dealer should reimburse the customer at the dealership. The dealership should then claim via the warranty process as set forth below in the “Warranty Information” section below. The warranty information sections detail steps for acquiring rentals. 19.

In some locations, a mobile inspection can be performed at a location of the customer’s convenience and towing will not be necessary. All towing will be provided free of charge to complete this recall. 20. Is mobile repair offered for this recall? a. Yes, for your convenience, an authorized Mercedes-Benz dealer will offer mobile inspection at a location of your choice. 21. I read a media article that states I should stop driving my vehicle if I own one of the affected vehicles, what should I do? a. A VIN-based recall lookup tool on our MBUSA.com website offers a search feature that will indicate whether a vehicle has been subject to a safety recall. See Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis https://www.mbusa.com/en/recall for more details.

Further instructions will be provided based on the results of that inspection. 22. What is Mercedes-Benz going to do for Owners given this inconvenience? a. Mercedes-Benz is committed to the highest level of customer service and while we regret the inconvenience, the safety of our customers is paramount. Mobility solutions and/or reimbursement for mobility will be offered for the duration the customer’s vehicle is affected under this “stop drive” recall. See the “Warranty Information” section below for further information. 23. For cars currently at the dealers, should dealers inform their customers and ensure dealer staff do not drive the vehicle? a. For customers Yes, dealers should inform their customers that the vehicle is under a stop drive recall. The vehicle can be stored at the dealership, or towed to the customer’s residence free of charge. Please contact the CAC at 1-888-548-8514 to schedule a tow. If the customer needs alternative transportation, a mobility solution will be offered to you by the dealer (See FAQ 4). Reimbursements will be provided up to a maximum of $80 per day. b. For dealer staff Dealer staff must NOT drive the vehicle on public roads. Within the confines of the dealership, the vehicle can be driven up to 20 mph. To claim any expenses related to towing and/or storage, see the “Reimbursement/Owner Pay” section below. STORAGE 24. Where will the vehicle be stored? a. Customers may store the vehicle at their residence and are encouraged to request their dealer perform a mobile inspection. Should the vehicle not pass the inspection, the vehicle may be continued to be stored at their residence or at their preferred dealer. Dealers need to order and perform the booster replacement now that parts are available. REIMBURSEMENTS/OWNER PAY 25. I may have paid for repairs related to this recall. Will I receive reimbursement? a. Current and previous owners may be eligible to receive reimbursement if they have had a brake booster replacement due to the conditions specified in this recall. Requests for reimbursement may include parts, labor, fees and taxes. Reimbursement may be limited to the amount the repair would have cost if completed by an authorized Mercedes-Benz dealer. Details were provided in the recall owner notification letter, which can be viewed on https://www.mbusa.com/en/recall. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 26. What happens if the dealer determines repairs aren’t necessary now but Owners experience concerns related to the recall in the future? Are Owners responsible for diagnostic fees/repair costs? a. Any future owner concerns will be evaluated on an individual basis. Extensive analyses were conducted by Mercedes-Benz AG. Based on these analyses, a test method was developed for the workshops which, among other aspects, ensures the functionality of the brake booster by usage of diagnostic-supported test routines. 27. I inspected the vehicle and found other brake components to be in need of repair. a. This recall relates to potential advanced corrosion on the brake booster housing. If other brake system component(s) are in need of repair/replacement such that they would impair or hinder performing the inspection for the recall condition, the parts/system must be rectified prior so the initial inspection may be completed. These parts and labor are not covered under this recall. 28. I received a letter but I no longer own the vehicle. How can I update my ownership information? a. Customers should be directed to the MBUSA recall website at https://www.mbusa.com/en/recall, enter their VIN, and update their contact information. 29. I lost faith in the vehicle and demand MBUSA provide a replacement. a. Such customer inquiries will be evaluated on a case-by-case basis. Direct the customer to 1-888-548-8514. 30. Can/should dealers wholesale/sell affected used car vehicles? a. No. MBUSA advises dealers not to sell used vehicles subject to this recall until the inspection and, if necessary, brake booster replacement is completed. 31. While performing the Xentry diagnostic test the technician finds a brake fluid leak, can this be covered under warranty? a. Yes. If while performing the inspection procedure other components fail then this would be claimable on the same line as the recall and considered primary loss. 32. While performing the Xentry diagnostic test, the brake line needed to be repaired. How do I address this? a. Follow AR42.10-P-0020A and utilize flaring kit A000 589 20 99 00 to construct brake lines from bulk stock. 33. If the vehicle fails the Xentry diagnostic pressure test, does the RO need to stay open? a. No, close the RO and submit the claim based on the warranty codes provided below in the work instructions section. The dealership may choose to open another RO until the parts replacement is complete. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 34. The customer wishes to keep driving the vehicle and refuses the repair. How do I handle this situation? a. Customer safety is our top priority at Mercedes-Benz. If the customer insists on driving the vehicle despite the warnings associated with a “stop drive” recall, the following language MUST be added to the Repair Order and initialed by the customer: (Initial Here) ASSUMPTION OF RISK FOR REMOVAL OF VEHICLE. I understand that my vehicle is subject to a “Stop Drive” recall and that continuing to drive my vehicle involves inherent risks and dangers of accidents, property loss or damage, and serious personal injury to me and others, as well as potential financial losses. I have carefully considered the extent of the risks involved, and I voluntarily and freely choose to assume these risks. 35. Is there a point of contact for the dealership, AOM’s, or other field personnel to request technical information or assistance relating specifically to the Xentry diagnostic test? a. The Work Instructions and Xentry diagnostic test have been verified prior to the recall launch. Thoroughly read the instructions, directions, and questions as presented in the Xentry diagnostic brake pressure test steps. If there are still questions after completing the first test, please open a PTSS case for the particular process or direction that is unclear. We do not anticipate any questions relating to the test at this time. 36. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a. Follow the same protocol used at your dealership when a customer refuses services offered. Also, make a notation on the RO that “customer refuses to initial the Assumption of Risk.” A customer signature must be recorded on the RO. 37. Now that the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? a. There should not be any Category 3 customers utilizing rental vehicles, storage, etc… as sufficient parts inventory for Category 3 vehicles has been available since October 2022. b. In the event a dealer cannot perform the brake booster replacement immediately, see below damage codes. i. Damage code 99803 01 – Mobile inspection incentive 1. $150 per vehicle 2.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 Campaign No. 2022050014, May 2022 Revision F 02/13/2023 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2007-2008 Inspect Brake Booster – with Pedal Rework Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2007-2008 ML, GL (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers were mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed.

P-RC-2022050014 17 P-RC-2022050014 Certificate of Passed Initial Diagnostic Brake Test Recall campaign – Inspect Brake Booster Vehicle identification number: Dear Valued Customer: Your vehicle’s brake booster has been inspected by your authorized Mercedes-Benz service facility for corrosion and functionality under MBUSA Recall Campaign number 2022050015 or 2022050014 bearing NHTSA ID# 22V315. The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis TO: Mercedes-Benz Dealer Principals, General Managers, Sales Managers, Service Managers, Parts Managers RE: Updated Recall Campaign Launch Notification – FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services STOP DRIVE Inspect Brake Booster without Pedal Rework MY06-12 GL-Class, ML-Class, R-Class (X164, W164, V251 platform) UPDATE: March 10, 2023 News Channel Update | Vehicle Compliance & Analysis Recall Campaign Launch Notification Campaign No. : NHTSA ID Campaign Desc. : 2022050015 22V315 22P4290005 March 10, 2023 Inspect Brake Booster Without Pedal Rework This is to notify you of an update to the Recall Campaign Launch to inspect the brake booster on 278,173 Model Year (“MY”) 2006-2012 GL- Class, ML-Class, and R-Class (X164, W164 and V251 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML-Class, GL-Class (W164/X164 platform) and R-Class (V251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, inspect the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. The remedy is available and can be performed. Vehicles Affected Vehicle Model Year(s) Vehicle Model 2006-2012 GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population Total Vehicles in Dealer Inventory 278,173 0 Vehicles are flagged as “OPEN” and Work Instructions are available in Star TekInfo. Customers are advised not to drive their vehicle until an inspection is performed. Based on the results, vehicles may continue to be driven if the inspection is passed, or must be grounded if the inspection is not passed. A follow-up campaign will be issued for any vehicle that requires a brake booster replacement. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY 06-12 GL-Class, ML-Class, and R- Class vehicles covered by this notification until the vehicle has been inspected and passed, or grounded until parts become available and the remedy performed.

Process Flow Category 3 Launch Process Flow (October 2022-February 9th, 2023) At the time of the Category 3 launch in October 2022, two processes occurred in tandem: 1) The dealer was required to close out campaign 2022050014 or 2022050015 for the inspection. a. This triggered a new campaign based on the warranty claim operation codes. If operation codes were claimed that matched Category 2, those vehicles would be moved into a new “PENDING” campaign on a weekly basis due to insufficient parts availability. If the operation codes claimed matched Category 3, vehicles would be moved to a new “OPEN” campaign, also on a weekly basis. b. This process only affected the opening of new campaigns in VMI and was irrespective of parts’ shipments. 2) The dealer was required to claim the correct warranty operation codes for Category 3. a. Once the operation codes were submitted and paid, if they matched the Category 3 warranty operation codes, a booster and, if necessary, a pedal kit were released automatically. This was done to prevent dealers from over-ordering critical parts quantities. Category 2 & 3 Launch Process Flow (February 10th, 2023-Current) 1) Dealers are still required to close the inspection campaigns for a new campaign to be opened. This process will remain the same as point 1 from the “Category 3 Launch Process Flow” above until further notice. An update to the NCU will be issued when this process is also revoked. 2) With parts for Category 2 vehicles now available, point 2 from the above “Category 3 Launch Process Flow” above have been revised. Warranty operation codes must still be claimed correctly, however, parts will no longer be released automatically. The dealer must now order parts by VIN via the parts ordering system. There will be no initial parts allocation since Category 2 vehicles could be driven up to 2 years prior to replacement. Further details below in the FAQ’s, including the quantity limit of parts dealers may order. 3) Important! Inspection claims still need to be submitted correctly with the proper warranty operation codes. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs SUMMARY OF RECALL 1. What is the recall about? a. The recall campaign is related to the brake booster housing. Specifically, advanced corrosion may have formed on the housing, which could lead to a vacuum leak and impairment to brake effectiveness. 2. What’s the difference between Campaign 2022050014 and 2022050015. a. The inspection is the same, however, different damage codes apply based on the vehicle population. One population requires a pedal rework, the other does not. 3. Can I continue to drive the car? a. Your safety is our highest priority. MBUSA advises customers to stop driving the vehicle until the first inspection is performed. Customers were notified by first class mail to schedule an appointment to have the inspection performed by an authorized dealer. 4. Why are other models not included? a. Only ML- (MY2006 – 2011), GL- (MY2007 – 2012), and R- (MY2006 – 2012) Class vehicles are fitted with the affected brake booster utilizing a rubber sleeve. Other models are not fitted with this rubber sleeve. Affected vehicles have been identified within this recall. 5. What types of repairs or replacements part(s) are needed? a. Affected vehicles will be inspected as a first step. After this inspection, the vehicle will be given 1 of 2 statuses. 1. Inspected with no advanced corrosion: The rubber sleeve will be removed. The vehicle can be driven with no further action or customer follow-up required. 2. Inspected with advanced corrosion found: XENTRY tests must still be completed according to the work instructions below. The dealer will order a brake booster and replace. The dealer will hold the vehicle until the part arrives and subsequently replace the brake booster. See FAQ 22b for guidance on driving the vehicles. DEALER SHOULD NO LONGER PROVIDE THE “Certificates of Passed Initial Diagnostic Brake Test” TO CUSTOMERS. If the customer requests mobility, details are available in the “Mobility” and “Reimbursement/Owner Pay” FAQ below via loaners or rental options. 6. Will the dealer repair the vehicle with the same part(s)? a. No. Based on the initial inspection, if a replacement of the brake booster is necessary, the part will be removed and replaced with a new part that does not utilize a rubber sleeve. 7. Will the replacement part(s) fail again? a. No. Provided the recall timelines are followed, the inspections and remedial measures performed by your Mercedes-Benz dealership assure you that the recall condition is remedied. 8. How long will the vehicle need to be in the workshop? a. For your convenience, an authorized Mercedes-Benz dealer will offer mobile inspection at your location of choice. Should you request the vehicle be towed to a workshop, the time for the Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis recall will vary and is dependent on towing availability and dealership schedules. The inspection itself will require 1 hour to complete. Additional time may be needed based on the results of the inspection. Your authorized Mercedes-Benz dealer can provide you with a better estimate of the overall time for this inspection. 9. A vehicle came in with no serial code on the brake booster unit and/or the brake booster is not the same color as in the work instruction pictures. What inspection procedure do I follow? a. Please open a PTSS case for verification of aftermarket booster and further processing. 10. Is there additional guidance other than the Work Instructions? a. There is an AKUBIS video on the intranet Learning Link titled “Brake Booster Inspection and Test” (X0027E-US.TTA). This should be used as a GENERAL PROCESS GUIDELINE ONLY. The work instructions attached to this NCU are the main technical resource for performing the recall inspection. Parts 11. Are parts available to replace brake boosters? a. Yes. 12. How will I receive the parts necessary to complete the campaign? a. The prior Category 3 parts release procedures are being revised. Brake boosters will no longer automatically be released. The parts system block for boosters and the pedal retrofit kits have been lifted. Dealers must enter a unique VIN and order parts specific to that vehicle. A single VIN may not be used to order multiple parts. Note: Additional pedal retrofit kits are not available and are unnecessary to be stocked at dealerships. Order ONLY after it is determined that a vehicle needs the retrofit kit based on the campaign number. 13. Will parts be pushed for vehicles? a. No. Parts need to be ordered by the dealerships for any existing or newly inspected vehicles that failed the visual inspection as of February 10, 2023. Parts will no longer automatically be pushed to dealerships. 14. After vehicle inspection, will another campaign open to replace the booster? a. Yes, once the inspection campaign has been closed, a new campaign will open. These new campaigns are opened on a weekly basis. If the dealer has determined a vehicle fails visual inspection (formerly Category 2 or 3), repair parts need to be ordered by the dealer and can be replaced even if the campaign isn’t open in VMI yet. The RO can be closed once the new campaign is activated. MOBILITY 15. Will the dealer provide a loaner vehicle? a. The dealer may offer to provide a loaner based on loaner vehicle availability. If available, the loaner will be provided free of charge. If no loaner vehicles are available, other solutions will be offered such as taxi/rideshare, public transportation cost reimbursement, and rental reimbursement. See the “Reimbursements/Owner Pay” section below for additional information. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 16. Are rental vehicles still allowed? a. Rental vehicles are only applicable to two groups of vehicles: i. Vehicles awaiting the initial inspection campaign. Once the vehicle inspection has been completed, the owner of any vehicle with a Category 1 should promptly turn in the rental vehicle. ii. Vehicles that did not pass visual inspection. With the launch of the booster replacement campaign for Category 3 vehicles in October 2022 and Category 2 vehicles in February 2023, no such owner should be in, or require a long-term rental. The only allowable rental is for vehicles that did not pass the visual inspection and is only for the time between inspection and parts arrival/booster replacement, which will only be a few days at maximum. Dealers are required to promptly order parts. 17. How does the dealer handle rental reimbursements? a. The dealer should reimburse the customer at the dealership. The dealership should then claim via the warranty process as set forth below in the “Warranty Information” section below. The warranty information sections detail steps for acquiring rentals. 18.

A tow can be completed by the local dealer or by calling 1-888-548-8514. Full details are available in the owner notification letter. In some locations, a mobile inspection can be performed at a location of the customer’s convenience and towing will not be necessary. All towing will be provided free of charge to complete this recall. 19. Is mobile repair offered for this recall? a. Yes, for your convenience, an authorized Mercedes-Benz dealer will offer mobile inspection at a location of your choice. 20. I read a media article that states I should stop driving my vehicle if I own one of the affected vehicles, what should I do? a. A VIN-based recall lookup tool on our MBUSA.com website offers a search feature that will indicate whether a vehicle has been subject to a safety recall. See https://www.mbusa.com/en/recall for more details. If your vehicle status is listed as “Open,” the vehicle MUST NOT be driven until the inspection process is performed. Further instructions will be provided based on the results of that inspection. 21. What is Mercedes-Benz going to do for Owners given this inconvenience? a. Mercedes-Benz is committed to the highest level of customer service and while we regret the inconvenience, the safety of our customers is paramount. Mobility solutions and/or reimbursement for mobility will be offered for the duration the customer’s vehicle is affected under this “stop drive” recall. See the “Warranty Information” section below for further information. 22. For cars currently at the dealers, should dealers inform their customers and ensure dealer staff do not drive the vehicle? Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis a. For customers Yes, dealers should inform their customers that the vehicle is under a stop drive recall. The vehicle can be stored at the dealership, or towed to the customer’s residence free of charge. Please contact the CAC at 1-888-548-8514 to schedule a tow.

To claim any expenses related to towing and/or storage, see the “Reimbursement/Owner Pay” section below. STORAGE 23. Where will the vehicle be stored? a. Customers may store the vehicle at their residence and are encouraged to request their dealer perform a mobile inspection. Should the vehicle not pass the inspection, the vehicle may be continued to be stored at their residence or at their preferred dealer. Dealers need to order and perform the booster replacement now that parts are available. REIMBURSEMENTS/OWNER PAY 24. I may have paid for repairs related to this recall. Will I receive reimbursement? a. Current and previous owners may be eligible to receive reimbursement if they have had a brake booster replacement due to the conditions specified in this recall. Requests for reimbursement may include parts, labor, fees and taxes. Reimbursement may be limited to the amount the repair would have cost if completed by an authorized Mercedes-Benz dealer. Details were provided in the recall owner notification letter, which can be viewed on https://www.mbusa.com/en/recall. 25. What happens if the dealer determines repairs aren’t necessary now but Owners experience concerns related to the recall in the future? Are Owners responsible for diagnostic fees/repair costs? a. Any future owner concerns will be evaluated on an individual basis. Extensive analyses were conducted by Mercedes-Benz AG. Based on these analyses, a test method was developed for the workshops which, among other aspects, ensures the functionality of the brake booster by usage of diagnostic-supported test routines. 26. I inspected the vehicle and found other brake components to be in need of repair. a. This recall relates to potential advanced corrosion on the brake booster housing. If other brake system component(s) are in need of repair/replacement such that they would impair or hinder performing the inspection for the recall condition, the parts/system must be rectified prior so the initial inspection may be completed. These parts and labor are not covered under this recall. 27. I received a letter but I no longer own the vehicle. How can I update my ownership information? a. Customers should be directed to the MBUSA recall website at https://www.mbusa.com/en/recall, enter their VIN, and update their contact information.

Can/should dealers wholesale/sell affected used car vehicles? a. No. MBUSA advises dealers not to sell used vehicles subject to this recall until the inspection and, if necessary, brake booster replacement is completed. 30. While performing the Xentry diagnostic test the technician finds a brake fluid leak, can this be covered under warranty? a. Yes. If while performing the inspection procedure other components fail then this would be claimable on the same line as the recall and considered primary loss. 31. While performing the Xentry diagnostic test, the brake line needed to be repaired. How do I address this? a. Follow AR42.10-P-0020A and utilize flaring kit A000 589 20 99 00 to construct brake lines from bulk stock. 32. If the vehicle fails the Xentry diagnostic pressure test, does the RO need to stay open? a. No, close the RO and submit the claim based on the warranty codes provided below in the work instructions section. The dealership may choose to open another RO until the parts replacement is complete. 33. The customer wishes to keep driving the vehicle and refuses the repair. How do I handle this situation? a. Customer safety is our top priority at Mercedes-Benz. If the customer insists on driving the vehicle despite the warnings associated with a “stop drive” recall, the following language MUST be added to the Repair Order and initialed by the customer: (Initial Here) ASSUMPTION OF RISK FOR REMOVAL OF VEHICLE. I understand that my vehicle is subject to a “Stop Drive” recall and that continuing to drive my vehicle involves inherent risks and dangers of accidents, property loss or damage, and serious personal injury to me and others, as well as potential financial losses. I have carefully considered the extent of the risks involved, and I voluntarily and freely choose to assume these risks. 34. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 Campaign No. 2022050015, May 2022 Revision G 03/10/2023 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2006-2012 Inspect Brake Booster – without Pedal Rework Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers were mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. Prior to performing this Campaign: • VMI must be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly. • Please review the entire Campaign bulletin and follow the repair procedure exactly as described.

The current version of all add-ons must be installed. Make sure to follow the operation steps exactly as described in XENTRY Diagnosis. 1. Connect XENTRY Diagnosis. XENTRY must be connected via the cable with VCI/SD Connect. Note regarding vehicles with KeylessGo: Remove KeylessGo start button and perform test with ignition key. Do not perform any unnecessary braking procedures (maximum full-stop braking) before the test. As a rule, the test should be performed nonstop without interruption. In certain conditions, the XENTRY scope of testing can be interrupted while the test is ongoing (e.g. hydraulic system is leaky) (cancellation). In this case, please follow the user guidance in XENTRY/DAS Diagnosis, because notes on the causes will be displayed for you. IMPORTANT: If XENTRY/DAS Diagnosis requests that the brake pedal be withdrawn into the starting position toward the driver, this must be done by means of a powerful foot motion. Check brake booster with XENTRY/DAS. To do this, select the menu item “Main groups – Control units – Chassis – ESP-Electronic Stability Program – Complete list of guided tests – Braking power”. Then follow the user guidance in XENTRY/DAS Diagnosis. Print out the brake force “event log” after the test and store to a local HDD/computer storage location. a. XENTRY/DAS test not passed: Please perform this test again. Only perform this test twice. b. XENTRY/DAS test passed: Continue with operation step 2. If the XENTRY/DAS test was not passed the first time, you must perform a second XENTRY/DAS test. If this second test is now passed, continue with the operation step 2 of scope of testing B. IMPORTANT: Only perform the second test if the first XENTRY/DAS test was not passed. The second test must be invoiced using operation number 02-0245 or 02-0246. a.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs 1. Are parts available to start replacing brake boosters? a. Yes, the final phase of the brake booster campaign is currently being launched for Category 3 vehicles only. 2. How will I receive the parts necessary to complete the campaign? a. The initial wave of parts will be automatically pushed to the dealer where the category 3 vehicles were inspected and claimed under warranty. b. If you receive a brake booster and the vehicle is no longer at the dealership you may: i. Reach out directly to the customer and arrange towing back to the dealership. If the customer is closer to a different dealer, please advise to reach out and schedule an appointment, as their parts are ready and can be installed to complete the campaign and put the vehicle back in use. The closer dealer should then request the brake booster part directly from the prior servicing dealer using the D2D network. ii. Wait until the Category 3 customers receive their letter and schedule. c. Moving forward, if a vehicle receives Category 3 status after the initial parts push, a separate RO must be opened for the brake booster inspection campaign only. Once complete, close out the RO with the proper warranty codes provided in the inspection NCU. Please submit the claim for the inspection as soon as the RO is closed so that the vehicle can be categorized, a part can be automatically pushed to the dealer, and the vehicle can be added to the subsequent recall campaign to repair the brake booster. The dealer does not need to wait to see the open recall campaign in VMI if the brake booster parts arrive prior. 3. How often are vehicles added from the “Inspect Brake Booster” to the “Replace Brake Booster” campaign? a. Once per week on Thursday’s. This process does not affect the inspection campaign and parts shipments should a vehicle fall under point 2c. 4. When are Category 2 vehicles going to receive brake booster replacements? a. As parts become available an updated Launch NCU will be issued. No dates can be offered at this time. 5. Are Xentry inspection results audited for verification? a. Xentry log files may be spot checked to ensure the Xentry inspection procedure was performed correctly. Under NO CIRCUMSTANCES may any dealer skip the inspection or purposely influence the test to receive parts immediately. Dealers may be audited if parts ordering practices show potential maleficence. 6. I would like to order a spare parts stock to have on-hand just in case a vehicle is inspected and deemed Category 3. a. This is not permitted. It is understandable that a buffer stock would be beneficial but due to the ongoing parts constraints, this may take away from a customer who requires it immediately. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 7. How long does the customer have to return their loaner or rental vehicle once the category 3 vehicle is repaired? a. Five (5) days at most. This is to accommodate any customers out of town or with extenuating circumstances. For special cases, the dealer should assess the situation and offer feedback since each case will be unique. 8. Now the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? a. Yes, please see below. i. Damage code 99803 01 – Mobile inspection incentive 1. $150 per vehicle 2. Claimed separately and on top of the recall inspection ii. Damage code 99039 01 – Towing 1.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 9. Is there a simple flowchart to understand all of the campaign numbers? 10. Will I need any additional parts for the brake booster replacement? a. No. The dealer should not need any further parts. It’s always a good idea to check the parts you will be using prior to commencing with the replacement.

The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML-Class, GL-Class (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. The inspection procedure is available and can be performed. Parts are not available at this time should they be needed. Once parts are available, certain customers will be informed via a second owner notification letter to have a final repair performed.

Based on these analyses, a test method was developed for the workshops which, among other aspects, ensures the functionality of the brake booster by usage of diagnostic-supported test routines. If the dealer determines based on the inspection that the brake booster does not need to be replaced at this time but the owner experiences recall-related concerns in the future, a re-inspection may be carried out within 2 years to ensure the functionality of the brake booster. Parts and labor associated with the recall are free of charge to the customer. 20. I inspected the vehicle and found other brake components to be in need of repair. a. This recall relates to potential advanced corrosion on the brake booster housing. If other brake system component(s) are in need of repair/replacement such that they would impair or hinder performing the inspection for the recall condition, the parts/system must be rectified prior so the initial inspection may be completed. These parts and labor are not covered under this recall. 21. I received a letter but I no longer own the vehicle. How can I update my ownership information? a. Customers should be directed to the MBUSA recall website at https://www.mbusa.com/en/recall, enter their VIN, and update their contact information. 22. I lost faith in the vehicle and demand MBUSA provide a replacement. a. Such customer inquiries will be evaluated on a case by case basis. Direct the customer to 1-888-548-8514. 23. Can/should dealers wholesale/sell affected used car vehicles? a. No. MBUSA advises dealers not to sell used vehicles subject to this recall until the inspection is completed. 24. While performing the Xentry diagnostic test the technician finds a brake fluid leak, can this be covered under warranty? a. Yes. If while performing the inspection procedure other components fail then this would be claimable on the same line as the recall and considered primary loss. 25. While performing the Xentry diagnostic test, the brake line needed to be repaired. How do I address this? a. Follow AR42.10-P-0020A and utilize flaring kit A000 589 20 99 00 to construct brake lines from bulk stock.

If the vehicle fails the Xentry diagnostic pressure test, does the RO need to stay open? No, close the RO and submit the claim based on the warranty codes provided below. The dealership may choose to open another RO until the parts replacement is complete. 27. The customer wishes to keep driving the vehicle and refuses the repair. How do I handle this situation? a. Customer safety is our top priority at Mercedes-Benz. If the customer insists on driving the vehicle despite the warnings associated with a “stop drive” recall, the following language MUST be added to the Repair Order and initialed by the customer: (Initial Here) ASSUMPTION OF RISK FOR REMOVAL OF VEHICLE. I understand that my vehicle is subject to a “Stop Drive” recall and that continuing to drive my vehicle involves inherent risks and dangers of accidents, property loss or damage, and serious personal injury to me and others, as well as potential financial losses. I have carefully considered the extent of the risks involved, and I voluntarily and freely choose to assume these risks. 28. Is there a point of contact for the dealership, AOM’s, or other field personnel to request technical information or assistance relating specifically to the Xentry diagnostic test? a. The Work Instructions and Xentry diagnostic test have been verified prior to the recall launch. Thoroughly read the instructions, directions, and questions as presented in the Xentry diagnostic brake pressure test steps. If there are still questions after completing the first test , please open a PTSS case for the particular process or direction that is unclear. We do not anticipate any questions relating to the test at this time. 29. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a. Follow the same protocol used at your dealership when a customer refuses services offered. Also, make a notation on the RO that “customer refuses to initial the Assumption of Risk.” A customer signature must be recorded on the RO. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 Campaign No. 2022050015, May 2022 Revision C 06/22/2022 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2006-2012 Inspect Brake Booster – without Pedal Rework Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. Prior to performing this Campaign: • VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle.

The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

If the vehicle fails the Xentry diagnostic pressure test, does the RO need to stay open? a. No, close the RO and submit the claim based on the warranty codes provided below. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 26. The customer wishes to keep driving the vehicle and refuses the repair. How do I handle this situation? a. Customer safety is our top priority at Mercedes-Benz. If the customer insists on driving the vehicle despite the warnings associated with a “stop drive” recall, the following language MUST be added to the Repair Order and initialed by the customer: (Initial Here) ASSUMPTION OF RISK FOR REMOVAL OF VEHICLE. I understand that my vehicle is subject to a “Stop Drive” recall and that continuing to drive my vehicle involves inherent risks and dangers of accidents, property loss or damage, and serious personal injury to me and others, as well as potential financial losses. I have carefully considered the extent of the risks involved, and I voluntarily and freely choose to assume these risks. 27. Is there a point of contact for the dealership, AOM’s, or other field personnel to request technical information or assistance relating specifically to the Xentry diagnostic test? a.

We do not anticipate any questions relating to the test at this time. 28. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a. Follow the same protocol used at your dealership when a customer refuses services offered. Also, make a notation on the RO that “customer refuses to initial the Assumption of Risk.” A customer signature must be recorded on the RO. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 Campaign No. 2022050015, May 2022 Revision A 06/03/2022 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2006-2012 Inspect Brake Booster – without Pedal Rework Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. Prior to performing this Campaign: • VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle.

The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. The inspection procedure is available and can be performed. Parts are not available at this time should they be needed. Once parts are available, certain customers will be informed via a second owner notification letter to have a final repair performed.

We do not anticipate any questions relating to the test at this time. 32. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a. Follow the same protocol used at your dealership when a customer refuses services offered. Also, make a notation on the RO that “customer refuses to initial the Assumption of Risk.” A customer signature must be recorded on the RO. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 Campaign No. 2022050015, May 2022 Revision E 09/23/2022 TO: ALL MERCEDES-BENZ CENTERS SUBJECT: Model GL-Class, ML-Class, and R-Class (X164, W164 and 251 platform) Model Year 2006-2012 Inspect Brake Booster – without Pedal Rework Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML, GL (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed.

P-RC-2022050015 18 P-RC-2022050015 Certificate of Passed Initial Diagnostic Brake Test Recall campaign – Inspect Brake Booster Vehicle identification number: Dear Valued Customer: Your vehicle’s brake booster has been inspected by your authorized Mercedes-Benz service facility for corrosion and functionality under MBUSA Recall Campaign number 2022050015 or 2022050014 bearing NHTSA ID# 22V315. The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2007-2008 ML-Class, GL-Class (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. The inspection procedure is available and can be performed. Parts are not available at this time should they be needed. Once parts are available, certain customers will be informed via a second owner notification letter to have a final repair performed. Vehicles Affected Vehicle Model Year(s) Vehicle Model 2007-2008 GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population Total Vehicles in Dealer Inventory 14,123 0 The vehicles will be flagged as “OPEN” and Work Instructions will be available in Star TekInfo. Customers are advised not to drive their vehicle until an inspection is performed. Based on the results, vehicles may continue to be driven if the inspection is passed, or must be grounded if the inspection is not passed. A follow-up campaign will be issued for any vehicle that requires a brake booster replacement. Until such time, a “Pending” campaign will be assigned to these vehicles to ensure vehicle status is reflected in the VIN look-up tools mentioned below. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY 07-08 GL-Class, ML-Class, and R- Class vehicles covered by this notification until the vehicle has been inspected and passed, or grounded until parts become available and the remedy performed.

The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis TO: Mercedes-Benz Dealer Principals, General Managers, Sales Managers, Service Managers, Parts Managers RE: Updated Recall Campaign Launch Notification – FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services STOP DRIVE Inspect Brake Booster with Pedal Rework MY06-12 GL-Class, ML-Class, R-Class (X164, W164, V251 platform) UPDATE: March 10, 2023 News Channel Update | Vehicle Compliance & Analysis Recall Campaign Launch Notification Campaign No. : NHTSA ID Campaign Desc. : 2022050014 22V315 22P4290006 March 10, 2023 Inspect Brake Booster Without Pedal Rework This is to notify you of an update to the Recall Campaign Launch to inspect the brake booster on 14,123 Model Year (“MY”) 2006-2012 GL- Class, ML-Class, and R-Class (X164, W164 and V251 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML-Class, GL-Class (W164/X164 platform) and R-Class (V251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, inspect the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. The remedy is available and can be performed. Vehicles Affected Vehicle Model Year(s) Vehicle Model 2006-2012 GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population Total Vehicles in Dealer Inventory 14,123 0 Vehicles are flagged as “OPEN” and Work Instructions are available in Star TekInfo. Customers are advised not to drive their vehicle until an inspection is performed. Based on the results, vehicles may continue to be driven if the inspection is passed, or must be grounded if the inspection is not passed. A follow-up campaign will be issued for any vehicle that requires a brake booster replacement. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY 06-12 GL-Class, ML-Class, and R- Class vehicles covered by this notification until the vehicle has been inspected and passed, or grounded until parts become available and the remedy performed.

Process Flow Category 3 Launch Process Flow (October 2022-February 9th, 2023) At the time of the Category 3 launch in October 2022, two processes occurred in tandem: 1) The dealer was required to close out campaign 2022050014 or 2022050015 for the inspection. a. This triggered a new campaign based on the warranty claim operation codes. If operation codes were claimed that matched Category 2, those vehicles would be moved into a new “PENDING” campaign on a weekly basis due to insufficient parts availability. If the operation codes claimed matched Category 3, vehicles would be moved to a new “OPEN” campaign, also on a weekly basis. b. This process only affected the opening of new campaigns in VMI and was irrespective of parts’ shipments. 2) The dealer was required to claim the correct warranty operation codes for Category 3. a. Once the operation codes were submitted and paid, if they matched the Category 3 warranty operation codes, a booster and, if necessary, a pedal kit were released automatically. This was done to prevent dealers from over-ordering critical parts quantities. Category 2 & 3 Launch Process Flow (February 10th, 2023-Current) 1) Dealers are still required to close the inspection campaigns for a new campaign to be opened. This process will remain the same as point 1 from the “Category 3 Launch Process Flow” above until further notice. An update to the NCU will be issued when this process is also revoked. 2) With parts for Category 2 vehicles now available, point 2 from the above “Category 3 Launch Process Flow” above have been revised. Warranty operation codes must still be claimed correctly, however, parts will no longer be released automatically. The dealer must now order parts by VIN via the parts ordering system. There will be no initial parts allocation since Category 2 vehicles could be driven up to 2 years prior to replacement. Further details below in the FAQ’s, including the quantity limit of parts dealers may order. 3) Important! Inspection claims still need to be submitted correctly with the proper warranty operation codes. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs SUMMARY OF RECALL 1. What is the recall about? a. The recall campaign is related to the brake booster housing. Specifically, advanced corrosion may have formed on the housing, which could lead to a vacuum leak and impairment to brake effectiveness. 2. What’s the difference between Campaign 2022050014 and 2022050015. a. The inspection is the same, however, different damage codes apply based on the vehicle population. One population requires a pedal rework, the other does not. 3. Can I continue to drive the car? a. Your safety is our highest priority. MBUSA advises customers to stop driving the vehicle until the first inspection is performed. Customers were notified by first class mail to schedule an appointment to have the inspection performed by an authorized dealer. 4. Why are other models not included? a. Only ML- (MY2006 – 2011), GL- (MY2007 – 2012), and R- (MY2006 – 2012) Class vehicles are fitted with the affected brake booster utilizing a rubber sleeve. Other models are not fitted with this rubber sleeve. Affected vehicles have been identified within this recall. 5. What types of repairs or replacements part(s) are needed? a. Affected vehicles will be inspected as a first step. After this inspection, the vehicle will be given 1 of 2 statuses. 1. Inspected with no advanced corrosion: The rubber sleeve will be removed. The vehicle can be driven with no further action or customer follow-up required. 2. Inspected with advanced corrosion found: XENTRY tests must still be completed according to the work instructions below. The dealer will order a brake booster and replace. The dealer will hold the vehicle until the part arrives and subsequently replace the brake booster. See FAQ 22b for guidance on driving the vehicles. DEALER SHOULD NO LONGER PROVIDE THE “Certificates of Passed Initial Diagnostic Brake Test” TO CUSTOMERS. If the customer requests mobility, details are available in the “Mobility” and “Reimbursement/Owner Pay” FAQ below via loaners or rental options. 6. Will the dealer repair the vehicle with the same part(s)? a. No. Based on the initial inspection, if a replacement of the brake booster is necessary, the part will be removed and replaced with a new part that does not utilize a rubber sleeve. 7. Will the replacement part(s) fail again? a. No. Provided the recall timelines are followed, the inspections and remedial measures performed by your Mercedes-Benz dealership assure you that the recall condition is remedied. 8. How long will the vehicle need to be in the workshop? a. For your convenience, an authorized Mercedes-Benz dealer will offer mobile inspection at your location of choice. Should you request the vehicle be towed to a workshop, the time for the Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis recall will vary and is dependent on towing availability and dealership schedules. The inspection itself will require 1 hour to complete. Additional time may be needed based on the results of the inspection. Your authorized Mercedes-Benz dealer can provide you with a better estimate of the overall time for this inspection. 9. A vehicle came in with no serial code on the brake booster unit and/or the brake booster is not the same color as in the work instruction pictures. What inspection procedure do I follow? a. Please open a PTSS case for verification of aftermarket booster and further processing. 10. Is there additional guidance other than the Work Instructions? a. There is an AKUBIS video on the intranet Learning Link titled “Brake Booster Inspection and Test” (X0027E-US.TTA). This should be used as a GENERAL PROCESS GUIDELINE ONLY. The work instructions attached to this NCU are the main technical resource for performing the recall inspection. Parts 11. Are parts available to replace brake boosters? a. Yes. 12. How will I receive the parts necessary to complete the campaign? a. The prior Category 3 parts release procedures are being revised. Brake boosters will no longer automatically be released. The parts system block for boosters and the pedal retrofit kits have been lifted. Dealers must enter a unique VIN and order parts specific to that vehicle. A single VIN may not be used to order multiple parts. Note: Additional pedal retrofit kits are not available and are unnecessary to be stocked at dealerships. Order ONLY after it is determined that a vehicle needs the retrofit kit based on the campaign number. 13. Will parts be pushed for vehicles? a. No. Parts need to be ordered by the dealerships for any existing or newly inspected vehicles that failed the visual inspection as of February 10, 2023. Parts will no longer automatically be pushed to dealerships. 14. After vehicle inspection, will another campaign open to replace the booster? a. Yes, once the inspection campaign has been closed, a new campaign will open. These new campaigns are opened on a weekly basis. If the dealer has determined a vehicle fails visual inspection (formerly Category 2 or 3), repair parts need to be ordered by the dealer and can be replaced even if the campaign isn’t open in VMI yet. The RO can be closed once the new campaign is activated. MOBILITY 15. Will the dealer provide a loaner vehicle? a. The dealer may offer to provide a loaner based on loaner vehicle availability. If available, the loaner will be provided free of charge. If no loaner vehicles are available, other solutions will be offered such as taxi/rideshare, public transportation cost reimbursement, and rental reimbursement. See the “Reimbursements/Owner Pay” section below for additional information. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 16. Are rental vehicles still allowed? a. Rental vehicles are only applicable to two groups of vehicles: i. Vehicles awaiting the initial inspection campaign. Once the vehicle inspection has been completed, the owner of any vehicle with a Category 1 should promptly turn in the rental vehicle. ii. Vehicles that did not pass visual inspection. With the launch of the booster replacement campaign for Category 3 vehicles in October 2022 and Category 2 vehicles in February 2023, no such owner should be in, or require a long-term rental. The only allowable rental is for vehicles that did not pass the visual inspection and is only for the time between inspection and parts arrival/booster replacement, which will only be a few days at maximum. Dealers are required to promptly order parts. 17. How does the dealer handle rental reimbursements? a. The dealer should reimburse the customer at the dealership. The dealership should then claim via the warranty process as set forth below in the “Warranty Information” section below. The warranty information sections detail steps for acquiring rentals. 18.

A tow can be completed by the local dealer or by calling 1-888-548-8514. Full details are available in the owner notification letter. In some locations, a mobile inspection can be performed at a location of the customer’s convenience and towing will not be necessary. All towing will be provided free of charge to complete this recall. 19. Is mobile repair offered for this recall? a. Yes, for your convenience, an authorized Mercedes-Benz dealer will offer mobile inspection at a location of your choice. 20. I read a media article that states I should stop driving my vehicle if I own one of the affected vehicles, what should I do? a. A VIN-based recall lookup tool on our MBUSA.com website offers a search feature that will indicate whether a vehicle has been subject to a safety recall. See https://www.mbusa.com/en/recall for more details. If your vehicle status is listed as “Open,” the vehicle MUST NOT be driven until the inspection process is performed. Further instructions will be provided based on the results of that inspection. 21. What is Mercedes-Benz going to do for Owners given this inconvenience? a. Mercedes-Benz is committed to the highest level of customer service and while we regret the inconvenience, the safety of our customers is paramount. Mobility solutions and/or reimbursement for mobility will be offered for the duration the customer’s vehicle is affected under this “stop drive” recall. See the “Warranty Information” section below for further information. 22. For cars currently at the dealers, should dealers inform their customers and ensure dealer staff do not drive the vehicle? Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis a. For customers Yes, dealers should inform their customers that the vehicle is under a stop drive recall. The vehicle can be stored at the dealership, or towed to the customer’s residence free of charge. Please contact the CAC at 1-888-548-8514 to schedule a tow.

To claim any expenses related to towing and/or storage, see the “Reimbursement/Owner Pay” section below. STORAGE 23. Where will the vehicle be stored? a. Customers may store the vehicle at their residence and are encouraged to request their dealer perform a mobile inspection. Should the vehicle not pass the inspection, the vehicle may be continued to be stored at their residence or at their preferred dealer. Dealers need to order and perform the booster replacement now that parts are available. REIMBURSEMENTS/OWNER PAY 24. I may have paid for repairs related to this recall. Will I receive reimbursement? a. Current and previous owners may be eligible to receive reimbursement if they have had a brake booster replacement due to the conditions specified in this recall. Requests for reimbursement may include parts, labor, fees and taxes. Reimbursement may be limited to the amount the repair would have cost if completed by an authorized Mercedes-Benz dealer. Details were provided in the recall owner notification letter, which can be viewed on https://www.mbusa.com/en/recall. 25. What happens if the dealer determines repairs aren’t necessary now but Owners experience concerns related to the recall in the future? Are Owners responsible for diagnostic fees/repair costs? a. Any future owner concerns will be evaluated on an individual basis. Extensive analyses were conducted by Mercedes-Benz AG. Based on these analyses, a test method was developed for the workshops which, among other aspects, ensures the functionality of the brake booster by usage of diagnostic-supported test routines. 26. I inspected the vehicle and found other brake components to be in need of repair. a. This recall relates to potential advanced corrosion on the brake booster housing. If other brake system component(s) are in need of repair/replacement such that they would impair or hinder performing the inspection for the recall condition, the parts/system must be rectified prior so the initial inspection may be completed. These parts and labor are not covered under this recall. 27. I received a letter but I no longer own the vehicle. How can I update my ownership information? a. Customers should be directed to the MBUSA recall website at https://www.mbusa.com/en/recall, enter their VIN, and update their contact information.

Can/should dealers wholesale/sell affected used car vehicles? a. No. MBUSA advises dealers not to sell used vehicles subject to this recall until the inspection and, if necessary, brake booster replacement is completed. 30. While performing the Xentry diagnostic test the technician finds a brake fluid leak, can this be covered under warranty? a. Yes. If while performing the inspection procedure other components fail then this would be claimable on the same line as the recall and considered primary loss. 31. While performing the Xentry diagnostic test, the brake line needed to be repaired. How do I address this? a. Follow AR42.10-P-0020A and utilize flaring kit A000 589 20 99 00 to construct brake lines from bulk stock. 32. If the vehicle fails the Xentry diagnostic pressure test, does the RO need to stay open? a. No, close the RO and submit the claim based on the warranty codes provided below in the work instructions section. The dealership may choose to open another RO until the parts replacement is complete. 33. The customer wishes to keep driving the vehicle and refuses the repair. How do I handle this situation? a. Customer safety is our top priority at Mercedes-Benz. If the customer insists on driving the vehicle despite the warnings associated with a “stop drive” recall, the following language MUST be added to the Repair Order and initialed by the customer: (Initial Here) ASSUMPTION OF RISK FOR REMOVAL OF VEHICLE. I understand that my vehicle is subject to a “Stop Drive” recall and that continuing to drive my vehicle involves inherent risks and dangers of accidents, property loss or damage, and serious personal injury to me and others, as well as potential financial losses. I have carefully considered the extent of the risks involved, and I voluntarily and freely choose to assume these risks. 34. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a. Follow the same protocol used at your dealership when a customer refuses services offered. Also, make a notation on the RO that “customer refuses to initial the Assumption of Risk.” A customer signature must be recorded on the RO. 35. Now that the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 9 a.

Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis TO: Mercedes-Benz Dealer Principals, General Managers, Sales Managers, Service Managers, Parts Managers RE: Updated Recall Campaign Launch Notification – FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services STOP DRIVE Inspect Brake Booster with Pedal Rework MY07-08 GL-Class, ML-Class, R-Class (X164, W164, 251 platform) UPDATE: June 22, 2022 News Channel Update | Vehicle Compliance & Analysis Recall Campaign Launch Notification Campaign No. : NHTSA ID Campaign Desc. : 2022050014 22V315 22P4290006 June 22, 2022 Inspect Brake Booster With Pedal Rework This is to notify you of an update to the Recall Campaign Launch to inspect the brake booster on 14,123 Model Year (“MY”) 2007-2008 GL- Class, ML-Class, and R-Class (X164, W164 and 251 platform) vehicles. The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2007-2008 ML-Class, GL-Class (W164/X164 platform) and R-Class (251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, check the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Affected customers will be mailed a recall owner notification letter and instructed to stop driving their vehicles until the inspection process is completed. The inspection procedure is available and can be performed. Parts are not available at this time should they be needed. Once parts are available, certain customers will be informed via a second owner notification letter to have a final repair performed. Vehicles Affected Vehicle Model Year(s) Vehicle Model 2007-2008 GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population Total Vehicles in Dealer Inventory 14,123 0 The vehicles will be flagged as “OPEN” and Work Instructions will be available in Star TekInfo. Customers are advised not to drive their vehicle until an inspection is performed. Based on the results, vehicles may continue to be driven if the inspection is passed, or must be grounded if the inspection is not passed. A follow-up campaign will be issued for any vehicle that requires a brake booster replacement. Until such time, a “Pending” campaign will be assigned to these vehicles to ensure vehicle status is reflected in the VIN look-up tools mentioned below. Additionally, given this notice, it is a violation of Federal Law for car rental companies to rent MY 07-08 GL-Class, ML-Class, and R- Class vehicles covered by this notification until the vehicle has been inspected and passed, or grounded until parts become available and the remedy performed. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis Next Steps/Notes Customer Notification Timeline Owner notification letters will be mailed on or before June 30, 2022.

FAQs SUMMARY OF RECALL 1. What is the recall about? a. The recall campaign is related to the brake booster housing. Specifically, advanced corrosion may have formed on the housing, which could lead to a vacuum leak and impairment to brake effectiveness. 2. What’s the difference between Campaign 2022050014 and 2022050015. a. The inspection is the same, however, they have different damage codes. So please follow the instructions exactly for the respective campaign for your vehicle. 3. Can I continue to drive the car? a. Your safety is our highest priority. MBUSA advises customers to stop driving the vehicle until the first inspection is performed. Customers will be notified by first class mail to schedule an appointment to have the inspection performed by an authorized dealer. 4. Why are other models not included? a. Only ML- (MY2006 – 2011), GL- (MY2007 – 2012), and R- (MY2006 – 2012) Class vehicles are fitted with the affected brake booster utilizing a rubber sleeve. Other models are not fitted with this rubber sleeve. Affected vehicles have been identified within this recall. 5. What types of repairs or replacements part(s) are needed? a. Affected vehicles will be inspected as a first step. After this inspection, the vehicle will be given 1 of 3 statuses. A. Inspected with no advanced corrosion: The rubber sleeve will be removed. The vehicle can be driven with no further action or customer follow-up required. B. Inspected with advanced corrosion found: A brake efficacy test will be performed. A passed test ensures the tested brake booster can continue to be used and the vehicle driven up to a maximum time limit of 2 years. The dealer will provide a “Certificate of Passed Initial Diagnostic Brake Test” detailing that the test has passed. A new notice will be provided to the owner at a later date to bring the vehicle to an authorized Mercedes- Benz dealership for further inspection and potential replacement of the brake booster.

The results of this initial inspection confirm that it is not immediately necessary to replace the brake booster in your vehicle. Therefore, your vehicle is no longer subject to the Stop Drive and may continue to be driven. A mobility solution is no longer necessary. Important! The brake booster may be subject to an additional inspection or a replacement brake booster, whichever comes first, within a period of 2 years from the date of the initial inspection. Mercedes-Benz USA will contact you again by mail to schedule the additional inspection at the appropriate time. If you sell your vehicle in the meantime, you must provide this document to the buyer. The additional inspection of the brake booster is very important to your vehicle’s safety. Therefore, it will be checked whether this has been carried out no later than 2 years after the first inspection. If this additional inspection was not carried out on your vehicle in time, you should stop operating the vehicle. If the described additional inspection is not completed, advanced corrosion in the joint area of the housing could potentially impair the function of the brake booster. This might increase the required brake pedal force and possibly extend the stopping distance. In very rare cases, it cannot be completely ruled out that mechanical damage to the brake booster might occur, whereby the connection between brake pedal and brake system would fail. In that condition, the vehicle would no longer be decelerated via the service brake which would increase the risk of a crash or injury. Date of inspection: Signature of Mercedes-Benz Dealer

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs 1. Are parts available to start replacing brake boosters? a. Yes, the final phase of the brake booster campaign is currently being launched for Category 3 vehicles only. 2. How will I receive the parts necessary to complete the campaign? a. The initial wave of parts will be automatically pushed to the dealer where the category 3 vehicles were inspected and claimed under warranty. b. If you receive a brake booster and the vehicle is no longer at the dealership you may: i. Reach out directly to the customer and arrange towing back to the dealership. If the customer is closer to a different dealer, please advise to reach out and schedule an appointment, as their parts are ready and can be installed to complete the campaign and put the vehicle back in use. The closer dealer should then request the brake booster part directly from the prior servicing dealer using the D2D network. ii. Wait until the Category 3 customers receive their letter and schedule. c. Moving forward, if a vehicle receives Category 3 status after the initial parts push, a separate RO must be opened for the brake booster inspection campaign only. Once complete, close out the RO with the proper warranty codes provided in the inspection NCU. Please submit the claim for the inspection as soon as the RO is closed so that the vehicle can be categorized, a part can be automatically pushed to the dealer, and the vehicle can be added to the subsequent recall campaign to repair the brake booster. The dealer does not need to wait to see the open recall campaign in VMI if the brake booster parts arrive prior. 3. How often are vehicles added from the “Inspect Brake Booster” to the “Replace Brake Booster” campaign? a. Once per week on Thursday’s. This process does not affect the inspection campaign and parts shipments should a vehicle fall under point 2c. 4. When are Category 2 vehicles going to receive brake booster replacements? a. As parts become available an updated Launch NCU will be issued. No dates can be offered at this time. 5. Are Xentry inspection results audited for verification? a. Xentry log files may be spot checked to ensure the Xentry inspection procedure was performed correctly. Under NO CIRCUMSTANCES may any dealer skip the inspection or purposely influence the test to receive parts immediately. Dealers may be audited if parts ordering practices show potential maleficence. 6. I would like to order a spare parts stock to have on-hand just in case a vehicle is inspected and deemed Category 3. a. This is not permitted. It is understandable that a buffer stock would be beneficial but due to the ongoing parts constraints, this may take away from a customer who requires it immediately. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 7. How long does the customer have to return their loaner or rental vehicle once the category 3 vehicle is repaired? a. Five (5) days at most. This is to accommodate any customers out of town or with extenuating circumstances. For special cases, the dealer should assess the situation and offer feedback since each case will be unique. 8. Now the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? a. Yes, please see below. i. Damage code 99803 01 – Mobile inspection incentive 1. $150 per vehicle 2. Claimed separately and on top of the recall inspection ii. Damage code 99039 01 – Towing 1. Up to $125 per tow if arranged by customer or dealer outside of normal process 2. Invoice must be attached to claim 3.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 9. Is there a simple flowchart to understand all of the campaign numbers? 10. Will I need any additional parts for the brake booster replacement? a. No. The dealer should not need any further parts. It’s always a good idea to check the parts you will be using prior to commencing with the replacement. Items such as brake lines (bulk brake line usage should be followed via WIS), electrical connector housings, and caliper bleed screws are all items to inspect. 11. Can a customer still request alternate mobility? a. For vehicles not yet inspected, MBUSA will provide mobility options within the program guidelines from the date of inspection request until the inspection is completed.

The recall campaign will be visible on the www.safercar.gov website and may generate questions from customers. Affected VINs were flagged in VMI as “OPEN” on May 28, 2022. Background Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2006-2012 ML-Class, GL-Class (W164/X164 platform) and R-Class (V251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal Issue What We’re Doing Parts forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, inspect the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. The remedy is available and can be performed.

I read a media article that states I should stop driving my vehicle if I own one of the affected vehicles, what should I do? a. A VIN-based recall lookup tool on our MBUSA.com website offers a search feature that will indicate whether a vehicle has been subject to a safety recall. See https://www.mbusa.com/en/recall for more details. If your vehicle status is listed as “Open,” the vehicle MUST NOT be driven until the inspection process is performed. Further instructions will be provided based on the results of that inspection. REIMBURSEMENTS/OWNER PAY 15. I may have paid for repairs related to this recall. Will I receive reimbursement? a. Current and previous owners may be eligible to receive reimbursement if they have had a brake booster replacement due to the conditions specified in this recall. Requests for reimbursement may include parts, labor, fees and taxes. Reimbursement may be limited to the amount the repair would have cost if completed by an authorized Mercedes-Benz dealer. Details were provided in the recall owner notification letter, which can be viewed on Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis https://www.mbusa.com/en/recall. Additional information can be provided by your AOM if necessary. 16. I inspected the vehicle and found other brake components to be in need of repair. a. This recall relates to potential advanced corrosion on the brake booster housing. If other brake system component(s) are in need of repair/replacement such that they would impair or hinder performing the inspection for the recall condition, the parts/system must be rectified prior so the initial inspection may be completed. These parts and labor are not covered under this recall. 17. I received a letter but I no longer own the vehicle. How can I update my ownership information? a. Customers should be directed to the MBUSA recall website at https://www.mbusa.com/en/recall, enter their VIN, and update their contact information. 18. The customer wishes to keep driving the vehicle and refuses the repair. How do I handle this situation? a. Customer safety is our top priority at Mercedes-Benz. If the customer insists on driving the vehicle despite the warnings associated with a “stop drive” recall, the following language MUST be added to the Repair Order and initialed by the customer: (Initial Here) ASSUMPTION OF RISK FOR REMOVAL OF VEHICLE. I understand that my vehicle is subject to a “Stop Drive” recall and that continuing to drive my vehicle involves inherent risks and dangers of accidents, property loss or damage, and serious personal injury to me and others, as well as potential financial losses. I have carefully considered the extent of the risks involved, and I voluntarily and freely choose to assume these risks. 19. The customer wishes to keep driving the vehicle and is refusing to initial the “Assumption of Risk” on the Repair Order. How do I handle this situation? a. Follow the same protocol used at your dealership when a customer refuses services offered. Also, make a notation on the RO that “customer refuses to initial the Assumption of Risk.” A customer signature must be recorded on the RO. 20. Now that the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? a. There should not be any Category 3 customers utilizing rental vehicles, storage, etc… as sufficient parts inventory for Category 3 vehicles has been available since October 2022. b.

After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. If this were to occur, the brake force support might be reduced, leading to an increase in the brake pedal forces required to decelerate the vehicle, and/or increased stopping distances. Additionally, in rare cases of very severe corrosion, it might be possible for a particularly strong or hard brake application to cause mechanical damage in the brake booster, whereby the connection between brake pedal and brake system would fail. In such a very rare case, it would not be possible to decelerate the vehicle via the brake pedal. The risk of a crash or injury would be increased. The function of the parking brake is not affected by this issue. Before the issue occurs, the driver might notice a change in the brake pedal feel and/or hissing/airflow noises when applying the brake pedal. An authorized Mercedes-Benz dealer will remove the rubber sleeve from the brake booster housing, inspect the brake booster on the affected vehicles and, depending on the result of this inspection, replace as necessary. Prior to performing this Campaign: • VMI must be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly. • Please review the entire Campaign bulletin and follow the repair procedure exactly as described. Approximately 14,123 vehicles are affected.

Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis Process Flow Category 3 Launch Process Flow (October 2022-February 9th, 2023) At the time of Category 3 launch in October 2022, two processes happened in tandem: 1) The dealer needed to close out the inspection campaign. a. This would trigger a new campaign based on the warranty claim operation codes. If operation codes were claimed that matched Category 2, vehicles would be moved to a new “PENDING” campaign once a week due to insufficient parts stock. If the operation codes claimed matched Category 3, once a week vehicles would be moved to a new “OPEN” campaign. b. This process only affected opening new campaigns in VMI and did not have anything to do with parts shipment. 2) The dealer needed to claim the correct warranty operation codes for Category 3. a. Once the operation codes were submitted and paid, if they matched the Category 3 warranty operation codes, a booster and, if necessary, a pedal kit were sent out automatically. This was done to prevent over-ordering during a critical parts shortage. Category 2 & 3 Launch Process Flow (February 10th, 2023-Current) 1) Dealers still need to close the inspection campaigns to have a new campaign opened. This process will remain the same as point 1 from the “Category 3 Launch Process Flow” for the time being. An update to the NCU will be issued when this process is also revoked. 2) Now that parts for Category 2 vehicles are available, point 2 from the “Category 3 Launch Process Flow” above is being revised. Warranty operation codes still need to be claimed correctly, however, parts will no longer be shipped out automatically. The dealer must now order parts per VIN via the parts ordering system. There will be no initial parts push since Category 2 vehicles were allowed to drive up to 2 years prior to replacement. Further details below in the FAQ’s, including how many parts dealers are allowed to order. 3) Important! Inspection claims still need to be submitted correctly with the proper warranty operation codes for Category 1, 2 and 3 vehicles, respectively. Category 2 and 3 vehicles must still have Xentry Diagnosis results uploaded to pXD. Please also see #6 in the FAQs below. 4) FAQ’s below detail any open points dealers may have. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis FAQs 1. Are parts available to replace brake boosters? a. Yes, for Category 2 and 3 vehicles. 2. How will I receive the parts necessary to complete the campaign? a. The Category 3 parts procedures are being revoked. The parts system block for boosters and the pedal retrofit kits will be lifted. Dealers must put in a unique VIN and order parts only for that vehicle. Do not use the same VIN to order parts. Note: there are no extra pedal retrofit kits and these do not need to be stocked at dealerships. Order ONLY after it is determined that a vehicle needs the retrofit kit. 3. Will parts be pushed for Category 2 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category 2 vehicles. Parts will no longer automatically be pushed to dealerships. 4. Will parts still be pushed for Category 3 vehicles? a. No. Parts need to be ordered by the dealerships for any existing and new Category -3 vehicles. Parts will no longer automatically be pushed to dealerships. 5. After vehicle inspection, will another campaign open to replace the booster? a. Yes, once the inspection campaign has been closed, a new campaign will open. These new campaigns are opened once a week. If the dealer has deemed a vehicle falls into Category 2 or 3, parts need to be ordered by the dealer and can be replaced even if the campaign isn’t open in VMI yet. The RO can be closed once the new campaign is activated. 6. When I hover over the campaign, it still says Category 3 even though the vehicle was a Category 2. Why? a. This is being addressed, however, campaign functionality is not impaired in any way. 7. Are Xentry inspection results audited for verification? a. Xentry log files may be spot checked to ensure the Xentry inspection procedure was performed correctly. Under NO CIRCUMSTANCES may any dealer skip the inspection or purposely influence the test. Dealers may be audited if parts ordering practices show potential malfeasance. Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis 8. I would like to order spare parts stock to have on-hand. a. Due to limited availability of stock for Category 2 & 3 vehicles at this time, all orders are to be placed by VIN, for only a quantity of one. Once sufficient stock becomes available, standard ordering practices will resume. 9. How long does the customer have to return their loaner or rental vehicle once the category 3 vehicle is repaired? a. Five (5) days at most. This is to accommodate any out of town customers or if there are extenuating circumstances. For special cases, the dealer should assess the situation and offer feedback since each case will be unique. 10. Are rental vehicles still allowed? a. Rental vehicles are only applicable to two groups of vehicles: i. Vehicles awaiting the initial inspection campaign. Once the vehicle inspection has been completed, the owner of any vehicle with a Category 1 should promptly turn in the rental vehicle. ii. Category 2 & 3 vehicles. With the launch of the booster replacement campaign for Category 3 vehicles in October 2022 and Category 2 vehicles in February 2023, no such owner should be in or require a long-term rental. The only allowable rental for Category 2 & 3 vehicles is for the time between inspection and parts arrival/booster replacement, which will only be a few days at maximum. Dealers are required to promptly order parts for Category 2 & 3 vehicles. 11. Now that the vehicle has been repaired, do I need to close out any pending costs attributable to storage, maintenance, etc? a. There should not be any Category 3 customers in rental vehicles, storage, etc… as sufficient parts stock for Category 3 vehicles has been available since October 2022. b. In the event a dealer cannot perform the brake booster replacement immediately, see below damage codes. i. Damage code 99803 01 – Mobile inspection incentive 1. $150 per vehicle 2. Claimed separately and on top of the recall inspection ii. Damage code 99039 01 – Towing 1. Up to $125 per tow if arranged by customer or dealer outside of normal process 2. Invoice must be attached to claim 3. Please use normal CAC tow process whenever possible to alleviate reimbursement iii. Damage code 99046 01 – Vehicle storage 1. $15 per vehicle, per day for dealership onsite storage 2. Up to $56.25 per vehicle, per day for offsite storage 3. Invoice must be attached to claim 4. Submit every 30 days and then a final claim to reconcile Mercedes-Benz USA, LLC A Mercedes-Benz Group AG Company One Mercedes-Benz Drive Sandy Springs, GA 30328 770.705.0600 News Channel Update | Vehicle Compliance & Analysis iv. Damage code 99047 01 – Active vehicle care during vehicle storage 1. $300 per vehicle, one-time, for the entire period claimed at the end of the storage period (i.e. wash, maintain battery, move to avoid flat spots and brake corrosion, etc.) v. Damage code 99304 01 – Mobility solutions 1. Up to $2,400 for rental vehicle (up to $80/day), loaner ($80/day flat fee), taxi / rideshare services or use of public transportation 2. Dealers are encouraged to use loaner vehicles for customer requests. See sales NCU on changes to the CVP program and alternate mobility options. 3. Rental agreement, loaner agreement and/or invoice(s) must be attached to claim. 12. Is there a simple flowchart to understand all of the campaign numbers? 13. Will I need any additional parts for the brake booster replacement? a. No. The dealer should not need any additional parts. It is always a good idea to check the parts you will be using or removing prior to commencing with the replacement. Items such as brake lines (bulk brake line usage should be followed via WIS), electrical connector housings, and caliper bleed screws are all items to inspect.
