  SERVICE BRAKES, ELECTRICAL SYSTEM, POWER TRAIN

  I pulled into a parking space, cars on each side of me and car in front of me had pulled through the space to park. As I eased into the space, foot on brake, the car violently shook and surged forward, smashing into the rear of the car in front of me. The car continued to shake then moved to the left and crashed into the car in front of me to the left. The car that I hit in the rear was pushed into a car passing by them. So 4 cars involved due to this major malfunction. When the car stopped, I was able to put it in reverse and back up. I could not have done what happened on own. I had no control over the vehicle. Brakes were mush. My Mercedes also has a safety feature where if I get too close to a car, it will brake on its own. Red & yellow lights were flashing, the car shook during the entire event until it came to a stop. My insurance carrier, State Farm, had the car towed to the Mercedes dealership. The service technician saw no codes, therefore, they say nothing is wrong with the car. I know that cars do not always throw codes. I googled what my car did and it is a thing. The article gives suggestions as to what can be checked, but Mercedes refuses to check anything since no codes were there. State Farm asked to me ask for the black box info (Event Data Recorder), however, Mercedes refuses. The car is unsafe to drive. If it happened once, it will absolutely happen again. State Farm is having the car towed to a different body shop today, as Mercedes body shop is price gouging. I do not want to drive the car until they find out what happened and they keep telling me there's nothing wrong with the car. It is a safety hazard. Next time it happens, it could be a person in front, rather than a car. Can you help me? Photos show skid marks where the brakes were useless.

  UNKNOWN OR OTHER

  The back up camera makes a loud very distinct noise and attempts to cut on when not necessary. Pops up on screen going forward in addition to backwards like it is supposed to do. comes on when braking, turning, going over bumps, all reasons when not necessary and it is very distracting to the driver.
