Sudden acceleration of vehicle is very dangerous and frightening when it occurs. GMC needs to resolve this ASAP. The 2014 Terrain is the worst vehicle in terms of multiple, dangerous problems that have remained undiagnosed and unrepaired by the GMC master technicians. The vehicle is going back into the shop again for the tenth time since I bought my Terrain in June 2014
