5 Car Accelerates On Its Own problem

Failure Date: 03/09/2012

I was driving into a parking space in a parking lot and came to a stop when the car suddenly accelerated, jumped a curb which was five inches high and five inches wide, smashed into a fence and came to rest on a scattered pile of bricks. I hurt my knee which hit the dashboard. This injury did not require hospitalization although I was in a state of shock. There was considerable damage to the car which is now in the body shop. It will take three weeks at least to repair the car. In the meantime I am driving a rental car. I believe this could be a case of unintended sudden acceleration caused by an electronic malfunction. I think this accident needs to be investigated thoroughly.
