The car is out of control! It first began a couple of weeks ago when (1) the side view mirrors no longer closed automatically 2) Next, while I was driving, the car yesterday, the seat belt suddenly tightened as the car prepared for a sudden impact (which there was none).3) Today, the car refused to stop when I backed it out of the garage. It hit a tree behind us and the car has a rear dint! I am now fearful of driving this car. It needs major servicing or something!!! I have had it towed in to my local Mercedes-Benz dealer.
