NHTSA Complaint #10655013 — 2011 GMC TERRAIN

I HAVE TAKEN MY TERRAIN TO THE DEALERSHIP A COUNTLESS NUMBER OF TIMES FOR VARIOUS REPAIRS. THE LATEST ISSUE IS THE "ENGINE POWER IS REDUCED!" NOTIFICATION. WHILE I WAS AT A COMPLETE STOP, I HEARD AN EXTREMELY LOUD RATTLING NOISE COME FROM UNDER THE HOOD OF MY CAR. I TURNED THE IGNITION OFF TO SEE IF THE NOISE WOULD STOP. TO MY SURPRISE THE CAR DID NOT IMMEDIATELY RESTART. AFTER TURNING THE KEY SEVERAL TIMES THE CAR STARTED BUT WITH AN EVEN LOUDER RATTLING NOISE. I TRIED TO LATER TAKE THE CAR TO THE MECHANIC ONLY TO FIND THAT THE CAR WOULD NOT CRANK AGAIN. AFTER REPEATEDLY TRYING TO CRANK THE CAR, IT FINALLY STARTED. I WAS NOT ABLE TO DRIVE FASTER THAN 15 MILES PER HOUR. I LATER FOUND OUT THAT I NEEDED MUCH MORE THAN A CATALYTIC CONVERTER (GMC DEALERSHIP ADVISED THAT THIS MAY BE THE ISSUE), INSTEAD I NEEDED A NEW ENGINE THAT MAY NOT BE COVERED ALTHOUGH I WAS STILL WITHIN MY FACTORY WARRANTY. THIS CAR IS HORRIBLE STAY FAR, FAR AWAY... *TR
