While pulling into a parking spot very slow the vehicle accelerated and damaged car in front there are traction marks showing the sudden acceleration. The car would not stop until the ignition was turned off. Because the cars in front were hit I placed the car in park after the ignition was turned off.

To whom it may concern, yesterday, 3/22/15, my wife and I were driving while carol took her foot off the gas pedal as we were approaching a stop light. At that time the car started accelerating. Is this a new problem or has it been reported before" who do I contact to investigate this issue and ensure that my vehicle is safe" my daughter bought a 2014 GMC Terrain last year and I'm concerned about her vehicle as well.
