I was turning into a parking spot at a store when I tried to break the vehicle accelerated, then was forced into the wall and the vehicle, then went backwards, losing control, and continue to accelerate. The only way I was able to stop. The car is to put it and park and shut the engine off after hitting another vehicle behind me. I could not get out of the vehicle as the door was jammed when I got out of the vehicle it looks as if the steering column shaft came out of its place. It was exposed and stuck below the brake and gas pedals
