After pulling into a parking space, then braking, i backed up to realign the vehicle better. when i pulled in this time and brake, the vehicle did not stop. i continued to put my foot on the brake repeatedly, but the vehicle still did not stop. the engine then revved up and accelerated. at this same time the gear shift went into neutral and then back into drive. the vehicle finally came to a stop as it hit the building in front of me, causing damage to the building, and the front of my vehicle. i was able to back up the vehicle and park it in the parking space, with not problem braking it to stop this time. *tr
