Today while parking my van infront of a building, with my foot lightly on the brake- my van accelerated uncontrollably and smasjed into the building. Luckily I was only 2-3' away from the building- and no one was infront of me. The reving noise and speed at which I hit the building was shocking. I was afraid to drive it, suffered some whip lash and had it towed to a dealer. They have said they can't find anything wrong thru the diagnostic testing. I'm afraid to drive it again- Has this happened to anyone else? Searching the web I found that it has happened to other toyota models..
