“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.”
