The contact stated that while entering a parking space, the brakes failed and the vehicle went over a curb and slightly crashed into the front of a building. There was no damage to the vehicle because the vehicle was moving at such a slow rate of speed. The contact stated that the vehicle did not accelerate but continued rolling and would not stop. The dealer inspected the vehicle and determined there was nothing wrong with the vehicle. The vehicle was not repaired. The failure and the current mileage was 4,100.

Brake pedal is notchy or sticks during the initial portion of pedal travel. Inconsistent brake feel at each stop leads to over or under braking, depending on whether or not the pedal sticks. It has been diagnosed by Mercedes as an internally leaking brake booster, but they won't replace it, saying the part falls within specs. This car is a 2011 C300W4. This model is not listed in your pull down menu (I entered E class to complete the form).
