A few weeks ago I was engaging my GL into park at a store and the truck suddenly accelerated into the brick wall that was 3 feet from the parking spot. $17,000 in damage - evidenced that I braked- skid marks before the wall leads me to believe this was a mechanical failure with the tectonic parking shifter. A friend of a neighbor had the same thing happen. Both of us were given a the story by Mercedes that the vehicle codes were normal - vehicle is safe to drive and the assumption that we hit the gas instead of the brake. I don't want to drive my GL now. I don't trust the vehicle. Anyone else have a parking incident like mine. I feel like everyone thinks I am crazy.
