What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I was making a right turn onto a city street when I heard a click/ crack, the instrument panel lit up, and the steering wheel locked. I was not able to stop the car in time and hit a parked car. The engine did not turn off when this happened.
The braking system light comes on and message states please stop your, the braking system is defective. This happen several times I was in traffic. I could not stop and when I turn the vehicle on, this message comes on the dash board.
I had an accident today the 20th of september where another car crashed into me caused considerable amount of damage to the front. The other car was going at least 40-50 mph. The other car was not as damaged as mine and no injuries resulted yet. I am very concerned that the airbag system did not engage.
The contact stated that there was leakage coming from the driverâs and the passengerâs side sunroof. The contact stated that the vehicle was taken to a local dealer. The contact was informed that the only warranty would be for the module.
My wife was driving the car about 25 mph .she put on the brakes and a bright red signal appeared on the screen and the car brakes failed .to avoid an accident ,my wife drove into an uphill parking lot where the car came to a stop without the cars brakes help .after we calmed down ,we called aaa and had the car towed…
I am in immediate need of a confirmation that Mercedes Benz USA or any dealership performed a Sensotronic Brake Control services on my 2003 E500 Mercedes Benz relative to Safety Recall #[phone]. Is MZBUSA required to report ALL vehicles that were serviced under this recall?
The contact stated that there was no warning light illuminated. The vehicle was not taken to a local dealer nor an independent mechanic to be diagnosed. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 139,000.
While the vehicle was on the highway the car lost power. Pulled over for visual inspection, noticed the fuel was leaking rapidly. Immediately shut off the car. Had vehicle towed to local mercedes benz dealership. Dealer verified the tank was leaking.
