I almost went through the windshield however my seat belt didn't stop me or lock in place at all. I also contacted mercedes in april 2016 about my driver airbag that was recalled due to safety concerns and I still haven't been contacted for a resolution as I have reached out to them multiple times for options because…
With the gear selector in park and the passenger side front seat occupied, the vehicle rolled backwards from a 4.4 percent grade and overturned as it proceeded downhill. Inspection of the transmission parking gear revealed that the parking pawl had been activated but did not engage a parking gear slot.
The contact stated that the vehicle stalled. The brake warning light was illuminated. The vehicle was towed to a tow lot. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 88,000.
The contact stated that while the vehicle was parked and turned off, there was brake fluid leaking from the vehicle with the BRAKE warning light illuminated. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure.
My vehicle jerks back and forth at low acceleration, and it often goes into limp mode which makes the vehicle only drive at around 20 mph at most. I was on the highway, when this happened. I have a 722.9 transmission, and this is a common problem. Why is the snapping recalled?
