I have never had any issues other than the recalls with my tahoe. I pulled into a parking space at my bank. As I got into the space. The brakes went to the floor and I put both feet on the brake pedal at this point. The rpms went up. It was like the engine came to life by itself. It self accelerated over the concrete spacer and sidwalk into the bank's brick wall. The airbag deployed upon impact. There was never a time it decelerated. There was no one in the car but me thankfully. There were no warning lights. There were no bells warning of the failure. I would estimate it took 2-3 seconds to go from almost stopped in a parking space to hitting the brick. I am so shaken by this incident and I have no idea what to do. GMC has been informed.
