I was exiting a freeway offramp and as I was turning at a speed of approximately 35 mph, I had both hands on the steering wheel and full control, but the actual car wheels disengaged from the steering. The car went in a different direction than the steering wheel and hit a wall. I was able to reverse. But, as I kept driving, the steering wheel was not controlling the car wheels correctly. When I would turn the steering wheel, the car's wheels wouldn't obey.
