Mercedes-Benz Part 573 Submission
Original Submitted to Portal May 9, 2022 Chronology-Only section
Supplement to Original Submission
Chronology of Defect/Noncompliance Determination
In July 2021, MBAG launched initial investigations based on an individual field report from outside the US describing an instance in which a customer allegedly experienced a reduced brake force support. No damages or personal injuries were reported. Parts of the affected vehicle were requested for further analysis. MBAG determined that, in the analyzed case, the function of the brake booster was impaired and corrosion of the brake booster housing was observed.
Starting in August 2021, further analyses was conducted regarding a potential failure mechanism, root cause and potential consequences. These analyses included investigations of parts procured from used parts suppliers, corrosion tests and functional tests of the brake booster in order to study the influence of continuous corrosion to the mechanical integrity and function of the brake booster.
Additionally, in September 2021, a field study was initiated in order to analyze the level of corrosion on brake booster housings in vehicles in different countries and regions worldwide.
In November 2021, investigations were conducted to study mechanisms that might lead to water application on the brake booster, thus allowing the observed corrosion to initiate.
From December 2021 onwards, additional corrosion tests on used parts from the field were conducted together with the supplier in order to determine the further progression of corrosion on parts in the field and the impact to the functionality of the brake booster.
From January 2022, potentially affected vehicles in the field were determined based on production records and information on the development of the fleet in operation.
From March 2022 onwards, results of the field study were evaluated in order to determine the distribution of corrosion levels in the field and to prepare a risk evaluation.
In March 2022, only one case was identified in the US where poor brake performance was caused by a corroded brake booster.
On May 2, 2022, MBAG determined that a potential safety risk could not be ruled out and decided to conduct a recall.
MBUSA contacted the agency on May 5, 2022 to inform NHTSA of this safety recall, stop drive instructions and that communications with owners would start as soon as possible.
MBAG can confirm there are no crashes, injuries or deaths related to this defect.

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! STOP DRIVE – Your vehicle can be towed to an authorized dealer and a mobility solution provided or a mobile repair may be possible • An Inspect ion procedure is available • Schedule an appointment with your authorized Mercedes-Benz dealership as soon as possible. • This repair will be provided FREE of charge, Dear Mercedes-Benz Owner: 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 mobile 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.

Sincerely, Gregory Gunther Department Manager, Vehicle Compliance & Analysis TO: Mercedes-Benz Dealer Principals, General Managers, Sales Managers, Service Managers, Parts Managers FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services RE: Updated Recall Campaign Launch Notification – STOP DRIVE Inspect Brake Booster with Pedal Rework MY07-08 GL-Class, ML-Class, R-Class (X164, W164, 251 platform) UPDATE: July 22, 2022 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 Campaign Launch Notification July 22, 2022 Campaign No. : NHTSA ID Campaign Desc. : Inspect Brake Booster With Pedal Rework 2022050014 22V315 22P4290006 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 Issue 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 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. What We’re Doing 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. Parts 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) 2007-2008 Vehicle Model GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population 14,123 Total Vehicles in Dealer Inventory 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 FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services RE: Recall Campaign Launch Notification – STOP DRIVE Inspect Brake Booster with Pedal Rework MY07-08 GL-Class, ML-Class, R-Class (X164, W164, 251 platform) DATE: May 28, 2022 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 PUBLIC Recall Campaign Launch Notification May 28, 2022 Campaign No. : NHTSA ID Campaign Desc. : Inspect Brake Booster With Pedal Rework 2022050014 22V315 22P4290006 This is to notify you of 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 will be flagged in VMI as “OPEN” on May 28, 2022. Background Issue 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 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. What We’re Doing 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. Parts 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) 2007-2008 Vehicle Model GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population 14,123 Total Vehicles in Dealer Inventory 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 PUBLIC FAQs 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. 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. 3. 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. 4. 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 “Warranty Information” section below for additional information. 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. Next Steps/Notes Customer Notification Timeline Owner notification letters will be mailed on or before June 30, 2022. AOMS/SOMS AOMs – This recall may generate questions from your dealers. Please forward this notice to your dealers ASAP. Rental Fleet Partners Affected vehicles in your fleet should not be driven until the inspection has been performed and passed. Please contact your respective MBUSA fleet representative for further information and next steps. For repairs, please contact your preferred MBUSA dealer. While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle quality and customer satisfaction.

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 PUBLIC C. Inspected with advanced corrosion and brake efficacy test does not pass: The vehicle will require the brake booster housing to be replaced when parts are available. Until then, the vehicle MUST NOT be driven. 6. If I am advised not to drive my vehicle will towing be offered? a. Customers will be notified by first class mail that the inspection can be performed at an authorized dealer. A tow can be completed by the local dealer or by calling 1-888-548-8514. Full details will be 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. 7. 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. 8. If advanced corrosion is found (status B, question 5), why must I wait two years – can’t the dealer just replace the brake booster housing now? a. Sufficient part quantities are not yet available to offer a complete repair at this time. Mercedes-Benz assures all customers that the tests performed through the inspection procedure confirm that the brake booster will remain functioning normally until such time an additional inspection is deemed necessary within a 2-year period. Mercedes-Benz is working diligently with its suppliers to procure replacement parts as soon as possible. 9. 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. 10. 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 heavily dependent on towing availability and dealership schedules. The inspection itself will require 1 hour to complete. Your authorized Mercedes-Benz dealer can provide you with a better estimate of the overall time for this inspection. 11. 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. 12. Are Owners responsible for expenses related to the recall? a. No. Parts and labor will be provided free of charge. Alternate mobility solutions will be offered via MBUSA and/or an authorized Mercedes-Benz dealership. If the customer exceeds the limits of what Mercedes-Benz offers, they may be responsible for the additional expenses. 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 PUBLIC 13. 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 will be provided in the recall owner notification letter. 14. 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. 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. 15. 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. 16. 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. 17. 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. 18. 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. 19. 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 www.mbusa.com/recall for more details. If your vehicle status is listed as “Recall Currently Pending” or “Open,” the vehicle MUST NOT be driven until the inspection process is 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

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 Issue 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 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. What We’re Doing 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.

Campaign No. 2022050015, May 2022 Revision D 07/21/2022 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. 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 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

Campaign No. 2022050014, 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 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.

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 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. What We’re Doing 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. Parts 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) 2006-2012 Vehicle Model GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population 278,173 Total Vehicles in Dealer Inventory 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 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.

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 FROM: Gregory Gunther, Department Manager, Vehicle Compliance and Analysis, Engineering Services RE: Recall Campaign Launch Notification – STOP DRIVE Inspect Brake Booster without Pedal Rework MY06-12 GL-Class, ML-Class, R-Class (X164, W164, 251 platform) DATE: May 28, 2022 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 PUBLIC Recall Campaign Launch Notification May 28, 2022 Campaign No. : NHTSA ID Campaign Desc. : Inspect Brake Booster Without Pedal Rework 2022050015 22V315 22P4290005 This is to notify you of 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 251 platform) vehicles. 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 “OPEN” on May 28, 2022. Background Issue 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 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. What We’re Doing 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. Parts 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) 2006-2012 Vehicle Model GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population 278,173 Total Vehicles in Dealer Inventory 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 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. 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 PUBLIC FAQs 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. 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. 3. 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. 4. 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 “Warranty Information” section below for additional information. 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. Next Steps/Notes Customer Notification Timeline Owner notification letters will be mailed on or before June 30, 2022. AOMS/SOMS AOMs – This recall may generate questions from your dealers.

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 PUBLIC C. Inspected with advanced corrosion and brake efficacy test does not pass: The vehicle will require the brake booster housing to be replaced when parts are available. Until then, the vehicle MUST NOT be driven. 6. If I am advised not to drive my vehicle will towing be offered? a. Customers will be notified by first class mail that the inspection can be performed at an authorized dealer. A tow can be completed by the local dealer or by calling 1-888-548-8514. Full details will be 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. 7. 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. 8. If advanced corrosion is found (status B, question 5), why must I wait two years – can’t the dealer just replace the brake booster housing now? a. Sufficient part quantities are not yet available to offer a complete repair at this time. Mercedes-Benz assures all customers that the tests performed through the inspection procedure confirm that the brake booster will remain functioning normally until such time an additional inspection is deemed necessary within a 2-year period. Mercedes-Benz is working diligently with its suppliers to procure replacement parts as soon as possible. 9. 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. 10. 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 heavily dependent on towing availability and dealership schedules. The inspection itself will require 1 hour to complete. Your authorized Mercedes-Benz dealer can provide you with a better estimate of the overall time for this inspection. 11. 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. 12. Are Owners responsible for expenses related to the recall? a. No. Parts and labor will be provided free of charge. Alternate mobility solutions will be offered via MBUSA and/or an authorized Mercedes-Benz dealership. If the customer exceeds the limits of what Mercedes-Benz offers, they may be responsible for the additional expenses.

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

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 Issue 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 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. What We’re Doing 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.

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. 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 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

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

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 Issue 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 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. What We’re Doing 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. Parts 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) 2006-2012 Vehicle Model GL-Class, ML-Class, R-Class Vehicle Populations Total Recall Population 278,173 Total Vehicles in Dealer Inventory 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 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.
