The incident happened in a parking lot. Backing out of the parking space, there was a delivery truck parked right behind me. Backing out of my parking space, I hit the bumper of the truck (no damage to the truck). As I pulled back into my parking space the vehicle accelerated very rapidly in a distance of approx. 25 feet; the acceleration seemed "Hell cat" like. Slamming my foot on the brake did not help. The vehicle then hit a brick retaining wall deploying multiple air bags and causing enough vehicle damage that the insurance company declared it totaled. It is amazing that the vehicle hit the brick wall with enough intensity to deploy the air bags and cause considerable front end damage after traveling such a short distance (approx 25 ft). The vehicle is in the insurance company's possession. As such, I do not have access to the vehicle. Had the brick wall not been there, the vehicle could have hit other vehicles or pedestrians and I was lucky to only have minor bruises and abrasions. There was no warning what so ever that this was about to happen.
