Reported at 6,000 miles, April 2012 CrashInjury

Within two days' time, my 2012 GMC terrain stalled four different times, all at low speeds. The first time was backing out of the driveway; the other three happened the following day starting up from city street intersections. My concern is being rear-ended in those situations, or beginning to make a left hand turn in front of oncoming traffic thinking you have enough time and then having the car stall. Another concern is having the stalling issue occur at higher speeds, although that never happened to me.
