May, 2021 Dear Mercedes-Benz Owner, This notice is sent to you in accordance with the requirements of 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 2014-2020 C-Class, CLA-Class, GLA-Class, GLC-Class, GLE-Class Coupe, and S-Class vehicles. Our records indicate that your vehicle is included in the affected population of vehicles. What is the Concern? On certain Model Year (“MY”) 2014-2020 C-Class, CLA-Class, GLA-Class, GLC-Class, GLE-Class Coupe, and S-Class vehicles with a panoramic sunroof, the stationary roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair. In this case, the adhesion of the front panel to the vehicle body might deteriorate over time which could cause the front panel to partially or fully detach from the vehicle, increasing the risk of a crash and/or injury to other road users. To remedy this issue, an authorized Mercedes-Benz dealer will remove the bonded panel and will install a new front panel by following the detailed repair instructions and using the approved primer, cleaner, and adhesive. Unfortunately, the parts to remedy this are not yet available. We are working to obtain the necessary parts to correct this condition as quickly as possible.

FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : In this case, the adhesion of the front panel to the vehicle body might deteriorate gradually over time and could result in the front panel to partially or fully detach from the vehicle, increasing the risk of a crash and/or injury for other road users. Description of the Cause : Due to a deviation in the workshop repair process, the front panels may not have been bonded according to specifications during a prior repair Identification of Any Warning that can Occur : When the adhesion begins to deteriorate, the customer might observe a partially detached panel or excessive wind noises in the area of the sunroof while driving. Involved Components : Component Name 1 : Cover OSR Component Description : Cover OSR Component Part Number : A1177800022, A1567801200, A2057800022, A2057803300, A2227800022, A2227806200, A2927800900 Supplier Identification : Component Manufacturer Name : Mercedes-Benz AG Address : NR NR Country : NR Chronology : Part 573 Safety Recall Report 21V-197 Page 9 The information contained in this report was submitted pursuant to 49 CFR §573 In June 2020, NHTSA raised two VOQs to Mercedes-Benz describing instances in which the front roof panel forward of the panoramic sunroof had allegedly detached from the vehicle while it was traveling at highway speeds. MBAG launched an investigation and was able to verify from its internal documentation that in both cases the incorrect adhesive was used to bond the panels during a previous repair. MBAG also began to analyze its internal data related to detachment of the front roof panel to understand whether the incidents were indicative of a broader trend or isolated events and found a number of sporadic reports submitted between 2018 – 2020 involving claims of cracked or partially detached panels. MBAG also observed that all involved vehicles that had also undergone a prior service repair to the front roof panel. MBAG began to analyze whether there was a more systemic issue and whether it was related to a prior repair of the front roof panel. MBAG provided an update to NHTSA in December 2020 and NHTSA opened its Preliminary Investigation in January 2021. MBAG’s technical analysis was carried out from late 2020 and into the first quarter of 2021 and included an analysis of possible deviations from the published repair instructions as not all vehicles that had undergone a prior service repair necessarily reported a subsequent issue with the bonding of the panel. Test setups were prepared by recreating various repair scenarios where an incorrect pre-treatment and bonding adhesives other than the specific adhesive that had been approved for this repair. Sample roof panels were also returned from the field and analyzed which indicated how the pre-treatment, cleaning and primer application were actually being applied by Mercedes-Benz workshops and any third-party sublets and confirmed that there were deviations from the repair procedures. Please see updated Chronology Supplement. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will remove the bonded panel and will install a new front panel by following the detailed repair instructions and using the approved primer, cleaner and adhesive. Pursuant to 49 C.F.R. § 577.11(e), MBUSA plans to provide notice about pre-notice reimbursement to owners since some of the involved vehicles would have been previously subject to the condition described. How Remedy Component Differs from Recalled Component : Correct installation of the front panel. Cover OSR – A1177800022, A1567801200, A2057800022, A2057803300, A2227800022, A2227806200, A2927800900, A0099898571, A0099897571, A0059891971, A0009894905 Identify How/When Recall Condition was Corrected in Production : MBAG created a global Service Information to address the potential for improper repair of the front panel. Additionally MBUSA is communicating the topic to its authorized dealers regarding the proper repair procedures. This condition should no longer occur for repairs made as of the recall launch date. MBAG and MBUSA continue to evaluate and optimize the parts ordering and other processes to ensure the repair is being performed correctly and ensure only the authorized repair components are used, as well as dealer accountability for the repairs.

MBAG also began to analyze its internal data related to detachment of the front roof panel to understand whether the incidents were indicative of a broader trend or isolated events and found a number of sporadic reports submitted between 2018 – 2020 involving claims of cracked or partially detached panels. MBAG also observed that all involved vehicles that had also undergone a prior service repair to the front roof panel. MBAG began to analyze whether there was a more systemic issue and whether it was related to a prior repair of the front roof panel. MBAG provided an update to NHTSA in December 2020 and NHTSA opened its Preliminary Investigation in January 2021. MBAG’s technical analysis was carried out from late 2020 and into the first quarter of 2021 and included an analysis of possible deviations from the published repair instructions as not all vehicles that had undergone a prior service repair necessarily reported a subsequent issue with the bonding of the panel. Test setups were prepared by recreating various repair scenarios where an incorrect pre-treatment and bonding adhesives other than the specific adhesive that had been approved for this repair. Sample roof panels were also returned from the field and analyzed which indicated how the pre-treatment, cleaning and primer application were actually being applied by Mercedes-Benz workshops and any third-party sublets and confirmed that there were deviations from the repair procedures. Please see updated Chronology Supplement. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will remove the bonded panel and will install a new front panel by following the detailed repair instructions and using the approved primer, cleaner and adhesive. Pursuant to 49 C.F.R. § 577.11(e), MBUSA plans to provide notice about pre-notice reimbursement to owners since some of the involved vehicles would have been previously subject to the condition described. How Remedy Component Differs from Recalled Component : Correct installation of the front panel.

Additionally MBUSA is communicating the topic to its authorized dealers regarding the proper repair procedures. This condition should no longer occur for repairs made as of the recall launch date. MBAG and MBUSA continue to evaluate and optimize the parts ordering and other processes to ensure the repair is being performed correctly and ensure only the authorized repair components are used, as well as dealer accountability for the repairs.

FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : In this case, the adhesion of the front panel to the vehicle body might deteriorate gradually over time and could result in the front panel to partially or fully detach from the vehicle, increasing the risk of a crash and/or injury for other road users. Description of the Cause : Due to a deviation in the workshop repair process, the front panels may not have been bonded according to specifications during a prior repair Identification of Any Warning that can Occur : When the adhesion begins to deteriorate, the customer might observe a partially detached panel or excessive wind noises in the area of the sunroof while driving.

MBAG launched an investigation and was able to verify from its internal documentation that in both cases the incorrect adhesive was used to bond the panels during a previous repair. MBAG also began to analyze its internal data related to detachment of the front roof panel to understand whether the incidents were indicative of a broader trend or isolated events and found a number of sporadic reports submitted between 2018 – 2020 involving claims of cracked or partially detached panels. MBAG also observed that all involved vehicles that had also undergone a prior service repair to the front roof panel. MBAG began to analyze whether there was a more systemic issue and whether it was related to a prior repair of the front roof panel. MBAG provided an update to NHTSA in December 2020 and NHTSA opened its Preliminary Investigation in January 2021. MBAG’s technical analysis was carried out from late 2020 and into the first quarter of 2021 and included an analysis of possible deviations from the published repair instructions as not all vehicles that had undergone a prior service repair necessarily reported a subsequent issue with the bonding of the panel. Test setups were prepared by recreating various repair scenarios where an incorrect pre-treatment and bonding adhesives other than the specific adhesive that had been approved for this repair. Sample roof panels were also returned from the field and analyzed which indicated how the pre-treatment, cleaning and primer application were actually being applied by Mercedes-Benz workshops and any third-party sublets and confirmed that there were deviations from the repair procedures. Please see updated Chronology Supplement. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will remove the bonded panel and will install a new front panel by following the detailed repair instructions and using the approved primer, cleaner and adhesive. Pursuant to 49 C.F.R. § 577.11(e), MBUSA plans to provide notice about pre-notice reimbursement to owners since some of the involved vehicles would have been previously subject to the condition described.

Production Dates : FEB 19, 2013 – AUG 04, 2020 VIN Range 1 : Begin : NR End : NR Not sequential Part 573 Safety Recall Report 21V-197 Page 8 The information contained in this report was submitted pursuant to 49 CFR §573 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”) 2014 – 2020 CLA-Class, GLAClass, C-Class, S-Class, GLC-Class, and GLE-Class Coupe (117, 156, 205, 222, 253, and 292 platform, respectively) vehicles with a panoramic sunroof, the stationary roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : In this case, the adhesion of the front panel to the vehicle body might deteriorate gradually over time and could result in the front panel to partially or fully detach from the vehicle, increasing the risk of a crash and/or injury for other road users. Description of the Cause : Due to a deviation in the workshop repair process, the front panels may not have been bonded according to specifications during a prior repair Identification of Any Warning that can Occur : When the adhesion begins to deteriorate, the customer might observe a partially detached panel or excessive wind noises in the area of the sunroof while driving. Involved Components : Component Name 1 : Cover OSR Component Description : Cover OSR Component Part Number : A1177800022, A1567801200, A2057800022, A2057803300, A2227800022, A2227806200, A2927800900 Supplier Identification : Component Manufacturer Name : Mercedes-Benz AG Address : NR NR Country : NR Chronology : Part 573 Safety Recall Report 21V-197 Page 9 The information contained in this report was submitted pursuant to 49 CFR §573 In June 2020, NHTSA raised two VOQs to Mercedes-Benz describing instances in which the front roof panel forward of the panoramic sunroof had allegedly detached from the vehicle while it was traveling at highway speeds. MBAG launched an investigation and was able to verify from its internal documentation that in both cases the incorrect adhesive was used to bond the panels during a previous repair. MBAG also began to analyze its internal data related to detachment of the front roof panel to understand whether the incidents were indicative of a broader trend or isolated events and found a number of sporadic reports submitted between 2018 – 2020 involving claims of cracked or partially detached panels. MBAG also observed that all involved vehicles that had also undergone a prior service repair to the front roof panel. MBAG began to analyze whether there was a more systemic issue and whether it was related to a prior repair of the front roof panel. MBAG provided an update to NHTSA in December 2020 and NHTSA opened its Preliminary Investigation in January 2021. MBAG’s technical analysis was carried out from late 2020 and into the first quarter of 2021 and included an analysis of possible deviations from the published repair instructions as not all vehicles that had undergone a prior service repair necessarily reported a subsequent issue with the bonding of the panel. Test setups were prepared by recreating various repair scenarios where an incorrect pre-treatment and bonding adhesives other than the specific adhesive that had been approved for this repair. Sample roof panels were also returned from the field and analyzed which indicated how the pre-treatment, cleaning and primer application were actually being applied by Mercedes-Benz workshops and any third-party sublets and confirmed that there were deviations from the repair procedures. Please see updated Chronology Supplement. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will remove the bonded panel and will install a new front panel by following the detailed repair instructions and using the approved primer, cleaner and adhesive. Pursuant to 49 C.F.R. § 577.11(e), MBUSA plans to provide notice about pre-notice reimbursement to owners since some of the involved vehicles would have been previously subject to the condition described. How Remedy Component Differs from Recalled Component : Correct installation of the front panel. Cover OSR – A1177800022, A1567801200, A2057800022, A2057803300, A2227800022, A2227806200, A2927800900, A0099898571, A0099897571, A0059891971, A0009894905 Identify How/When Recall Condition was Corrected in Production : MBAG created a global Service Information to address the potential for improper repair of the front panel. Additionally MBUSA is communicating the topic to its authorized dealers regarding the proper repair procedures. This condition should no longer occur for repairs made as of the recall launch date. MBAG and MBUSA continue to evaluate and optimize the parts ordering and other processes to ensure the repair is being performed correctly and ensure only the authorized repair components are used, as well as dealer accountability for the repairs.

FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : In this case, the adhesion of the front panel to the vehicle body might deteriorate gradually over time and could result in the front panel to partially or fully detach from the vehicle, increasing the risk of a crash and/or injury for other road users. Description of the Cause : Due to a deviation in the workshop repair process, the front panels may not have been bonded according to specifications during a prior repair Identification of Any Warning that can Occur : When the adhesion begins to deteriorate, the customer might observe a partially detached panel or excessive wind noises in the area of the sunroof while driving. Involved Components : Component Name 1 : Cover OSR Component Description : Cover OSR Component Part Number : A1177800022, A1567801200, A2057800022, A2057803300, A2227800022, A2227806200, A2927800900 Supplier Identification : Component Manufacturer Name : Mercedes-Benz AG Address : NR NR Country : NR Chronology : Part 573 Safety Recall Report 21V-197 Page 9 The information contained in this report was submitted pursuant to 49 CFR §573 In June 2020, NHTSA raised two VOQs to Mercedes-Benz describing instances in which the front roof panel forward of the panoramic sunroof had allegedly detached from the vehicle while it was traveling at highway speeds. MBAG launched an investigation and was able to verify from its internal documentation that in both cases the incorrect adhesive was used to bond the panels during a previous repair. MBAG also began to analyze its internal data related to detachment of the front roof panel to understand whether the incidents were indicative of a broader trend or isolated events and found a number of sporadic reports submitted between 2018 – 2020 involving claims of cracked or partially detached panels. MBAG also observed that all involved vehicles that had also undergone a prior service repair to the front roof panel. MBAG began to analyze whether there was a more systemic issue and whether it was related to a prior repair of the front roof panel. MBAG provided an update to NHTSA in December 2020 and NHTSA opened its Preliminary Investigation in January 2021. MBAG’s technical analysis was carried out from late 2020 and into the first quarter of 2021 and included an analysis of possible deviations from the published repair instructions as not all vehicles that had undergone a prior service repair necessarily reported a subsequent issue with the bonding of the panel. Test setups were prepared by recreating various repair scenarios where an incorrect pre-treatment and bonding adhesives other than the specific adhesive that had been approved for this repair. Sample roof panels were also returned from the field and analyzed which indicated how the pre-treatment, cleaning and primer application were actually being applied by Mercedes-Benz workshops and any third-party sublets and confirmed that there were deviations from the repair procedures. Please see updated Chronology Supplement. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will remove the bonded panel and will install a new front panel by following the detailed repair instructions and using the approved primer, cleaner and adhesive. Pursuant to 49 C.F.R. § 577.11(e), MBUSA plans to provide notice about pre-notice reimbursement to owners since some of the involved vehicles would have been previously subject to the condition described. How Remedy Component Differs from Recalled Component : Correct installation of the front panel. Cover OSR – A1177800022, A1567801200, A2057800022, A2057803300, A2227800022, A2227806200, A2927800900, A0099898571, A0099897571, A0059891971, A0009894905 Identify How/When Recall Condition was Corrected in Production : MBAG created a global Service Information to address the potential for improper repair of the front panel. Additionally MBUSA is communicating the topic to its authorized dealers regarding the proper repair procedures. This condition should no longer occur for repairs made as of the recall launch date. MBAG and MBUSA continue to evaluate and optimize the parts ordering and other processes to ensure the repair is being performed correctly and ensure only the authorized repair components are used, as well as dealer accountability for the repairs.
