"TERRAIN hesitated getting out of driveway...then shut down....would not crank...dead stop....GMC sent wrecker to haul to dealer...replaced same day."

"My car left me stranded three weeks ago with no warning. It turned off as I was driving but I luckily could pull into a parking lot. I lease so everything was paid for (part, tow, car rental) but I didn't expect this from a car so new! I also lost a day of work."
