What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I noticed that my dashboard was lit up with warning signals and check engine light at the seen of the collision. The rear light was explainable as the light was knocked out in the crash. The engine light however was a bit of a mystery.
Vehicle takes to mercedes benz dealership on 8/31/07 for seat belt malfunction. Seat belt self-arresting. Mercedes benz inspects and determines "seat belt functioning properly". 2. Vehicle in a rear collision on 9/25/07 and seat belts do not arrest.
None of the air bags deployed and the seat belts failed to retract properly. Three occupants were moderately injured. The contact has a copy of the police report and pictures of the failed incident. He is in the process of calling the manufacturer in reference to nhtsa campaign id numbers 05v560000 (air bags).
The steering wheel failed to lock securely in place. The contact was able to drive to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 45,000.
We received a recall notice on our Mercedes stating that over time the bonding in the glass panel and sunroof frame might deteriorate over time and cause the glass to separate from the vehicle. On 02/06/25, my son brought his car into [dealer] Lafayette, Indiana to take care of the recall.
The contact stated that the vehicle failed to accelerate above 35 MPH with the traction control warning light illuminated. The contact stated that the vehicle started to stall while driving at various speeds.
The contact stated that while driving at an undisclosed speed, the vehicle started leaking oil. The check engine warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to an unknown recall.
The car randomly misfires and goes into limp mode with a flashing check engine light. This has occurred on roadways and the vehicle loses all engine power. My engine code, 272920 30 183997272.920, falls into a known range of balance shaft gear problems with this motor.
