NHTSA Complaint #10822819 — 2010 GMC TERRAIN

WHEN IN MOTION STABILITRAK LIGHT COMES ON, I RECEIVE THE MESSAGE "ENGINE POWERING DOWN", CAR SLOWS DOWN TO 10 MILES AN HOUR. YOU MUST PULL OFF ON SIDE OF ROAD TURN CAR OFF WAIT APPROXIMATELY 60 SEC AND RESTART CAR. THIS IS SO UNSAFE I AM AFRAID TO TAKE IT ON EXPRESSWAYS. TOOK TO DEALERSHIP THEY CLAIMED IT WAS TIMING CHAIN AT COST OF $2000. GOT GM AND DEALERSHIP TO PAY PART OF COST. THEN WAS TOLD IT NEEDED A SERPENTINE BELT AT AN ADDITIONAL COST OF COURSE. PICKED CAR UP AND THE VERY NEXT MORNING THE CAR DID IT AGAIN. TOOK VEHICLE BACK TO DEALERSHIP AND AM NOW BEING TOLD IT NEEDS A THROTTLE BODY AT AN ADDITIONAL COST OF $400. CHECK ENGINE LIGHT HAS BEEN ON THE WHOLE TIME. DO THEY REALLY KNOW WHATS WRONG WITH IT OR JUST SHOOTING IN DARK WHILE I SPEND MORE MONEY. THIS IS A SAFETY HAZARD!! CAR WAS BROUGHT IN WHILE STILL UNDER WARRANTY FOR CHECK ENGINE LIGHT THEY WERE NEVER ABLE TO DIAGNOSE A PROBLEM.
