Part 573 Safety Recall Report 21V-860 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 FMVSS 1 : 226 – Ejection mitigation FMVSS 2 : NR Description of the Safety Risk : In the event of a crash with activation of the driver-side window airbag, the catch strap of the driver-side window airbag in the lower area of the A-pillar could detach. In that case, local legal requirements according to FMVSS 226 might not be met. Therefore, the restraining effect of the window airbag might not function as specified in FMVSS 226, and increased risk of injury for the driver and left rear occupant cannot be ruled out. Description of the Cause : Due to a deviation in the production process, the driver-side window airbag might not be mounted correctly on certain vehicles.

Measures were implemented on the assembly line to ensure that the driver-side window airbag is mounted according to specifications. As a follow up measure, the production plant initiated a plant action to confirm that all vehicles that had been built prior to the implementation of these measures were equipped with a correctly installed driver-side window airbag. During a review of the plant action, MBAG found that vehicles may have been released from the plant prior to being inspected for the correct installation of the driver-side window airbag. Beginning of March, MBAG initiated analyses with regard to possible effects of the described issue. It was found that even in the event of an incorrect mounting of the driver-side window airbag in the lower area of the Apillar, the inflation of the driver-side window airbag might only deviate slightly. In the following months, test results were analyzed with regard to a potential safety impact. In September further analysis were conducted to asses potential deviations from requirements specified in FMVSS. On October 29, 2021, MBAG decided to conduct a recall due to the resulting non-compliance with portions of FMVSS 226. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will check the mounting of the driver-side window airbag on the affected vehicles and rework it, if necessary. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since none of the involved vehicles would have been previously subject to the condition described and all remain covered under the new vehicle warranty.

As a follow up measure, the production plant initiated a plant action to confirm that all vehicles that had been built prior to the implementation of these measures were equipped with a correctly installed driver-side window airbag. During a review of the plant action, MBAG found that vehicles may have been released from the plant prior to being inspected for the correct installation of the driver-side window airbag. Beginning of March, MBAG initiated analyses with regard to possible effects of the described issue. It was found that even in the event of an incorrect mounting of the driver-side window airbag in the lower area of the Apillar, the inflation of the driver-side window airbag might only deviate slightly. In the following months, test results were analyzed with regard to a potential safety impact. In September further analysis were conducted to asses potential deviations from requirements specified in FMVSS. On October 29, 2021, MBAG decided to conduct a recall due to the resulting non-compliance with portions of FMVSS 226. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will check the mounting of the driver-side window airbag on the affected vehicles and rework it, if necessary. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since none of the involved vehicles would have been previously subject to the condition described and all remain covered under the new vehicle warranty. How Remedy Component Differs from Recalled Component : Driver-side window airbag installed according to specification. Parts: Felt Strip – A0009838910, Anti-corrosive Agent – A000986727005, Identify How/When Recall Condition was Corrected in Production : A change in the production procedures ensures that this issue can no longer occur from February 3, 2021 onwards. Recall Schedule : Description of Recall Schedule : Dealers will be notified of the pending voluntary recall campaign on November 12, 2021. Owners notified of the voluntary recall campaign on December 21, 2021. A copy of all communications will be provided when available. Planned Dealer Notification Date : NOV 12, 2021 – NR Planned Owner Notification Date : DEC 21, 2021 – NR * NR – Not Reported
