NHTSA complaint #11538406

Owner complaint summary

I receive a passenger airbag warning message every time I start the vehicle. Took to Mercedes dealer 2/10/2023 and they diagnosed the airbag problem as being caused due to the failure of the weight sensor in the passenger seat. NO ETA on a part to fix the weight sensor in the seat and was given the vehicle back to drive as normal, despite the passenger airbag being disabled (vehicle is still under factory warranty period). Have returned the vehicle to the dealer again on 4/20/2023 and 5/30/3023 to try and expedite a fix but both times was told there was no ETA on a part to fix the weight sensor in the seat and was given the vehicle back to drive as normal, despite the passenger airbag being disabled. I opened an escalation with Mercedes Benz USA (ERM - Executive Referral Management team) on 7/7/2023 and they called the Mercedes dealer to confirm the airbag issue and tie to the bad weight sensor in the seat. The dealer re-confirmed with Mercedes Benz USA that they do not have an ETA to fix the passenger seat weight sensor, hence no way to fix the airbag malfunction. As I submit this on 8/14/2023 I still do not have a functioning passenger airbag and no ETA to get this issue resolved, despite trying for over 6 months. This has and continues to pose an incredible safety concern for passengers that ride in this vehicle as the airbag won't deploy if in an accident. Another unintended consequence is that the chime/ding to remind passengers to fasten their seat belt is disabled as it's also tied to the malfunctioning weight sensor in the seat. This is my only vehicle and I don't have any alternatives given I cannot sell this vehicle without a working airbag.
