Foreign States
Country : Germany Chronology :
In June 2020, MBAG received isolated cases from the field describing instances in which the front roof panel forward of the panoramic sunroof had allegedly detached from the vehicle. MBAG launched an investigation and was able to verify from its internal documentation that in these isolated cases the wrong 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 and found 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’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 one 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 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.

As a matter of normal service process, the authorized Mercedes-Benz dealer will also check for other repair measures that might be applicable to your vehicle, which may increase the required working time.

Production Dates : JUN 05, 2013 – FEB 21, 2020
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”) 2014 – 2020 C-Class (205 platform), CLA (117 platform), GLA (156 platform), S-Class (222 platform), GLC (253 platform), GLE Coupe (292 platform) vehicles with a panoramic sunroof, the stationary roof panel located between the windshield and the panoramic sunroof might not have been bonded correctly during a prior repair.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : In this case, the adhesion of the bonding 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, which could increase the risk of a crash and/or injury for other road users.
Description of the Cause : Due to a deviation in the workshop 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 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A117780002239 The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-854 Page 9 Component Name 2 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A117780020039 Component Name 3 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A176780002239 Component Name 4 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A205780002240 Component Name 5 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A205780330039 Component Name 6 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A2227806200 Component Name 7 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A292780090039 Component Name 8 : PANORAMIC ROOF Component Description : PANORAMIC ROOF Component Part Number : A156780002239 The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-854 Page 10 Supplier Identification : Component Manufacturer

Foreign States
Country : Germany Chronology :
In June 2020, MBAG received isolated cases from the field describing instances in which the front roof panel forward of the panoramic sunroof had allegedly detached from the vehicle. MBAG launched an investigation and was able to verify from its internal documentation that in these isolated cases the wrong 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 and found 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’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 one 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 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.
