After having this vehicle for 18 months the car began to freeze while backing uo. There are no objects, cars or humans anywhere around the vehicle when this occurs. The car was moving at a very low speed when all of a sudden the auto locks up and the brakes engage, you have to step on the brake in order to release the vehicle. This occurs while backing out of a parking space, my garage where there is nothing near the vehicle. I have taken the car to Audi 3 times and each time they tell me there is nothing wrong with the vehicle. I have also contacted Audi usa numerous times and was again told there is nothing wrong with the vehicle. I contacted Audi's executive offices as well.

I was driving on the highway in rainy conditions. (driving according to speed limit) and I suddenly lost control. The car wouldn't turn when I turned the wheel and started veering out of the lane. It then turned into the opposite direction into traffic and eventually spun to a stop.

When I got the car in May. After a week, we went with friends out. When I braked the car began to move into the passenger front seat to the advance and inclines up to a maximum front of the dashboard. So in case of a car accident, he would have been dead. Audi dealer they did not believe me and thought I was misinformed. And it was not hard braking, but normal braking (slowing down). Because many times it happened to me out of the car started to brake without a reason to brake, when I tried to go around bikers at the safe distance, or when parking (until today). When I made the complaint in the Audi dealer, before, they told me that this is not possible, and laughed in June.
