2017 GMC Terrain

MY CHECK ENGINE LIGHT CAME ON ALONG WITH A A MESSAGE THAT STATES 'REDUCED ENGINE POWER' AND A MESSAGE READING 'SERVICE STABILITREK WHEN I WAS DRIVING ON THE HIGHWAY AT 70 MPH. THIS CREATED SUDDENLY JERKING AND SLOW ACCELERATION SO THAT I HAD TO PULL OFF THE ROAD. I FOUND A FORUM AT [XXX] THAT REVEALS THAT THIS HAS BEEN AN ISSUE WITH GMC MODES AT LEAST AS LONG AS 2011. THE DURATION FOR WHICH THIS HAS BEEN A PROBLEM WITH GMC MODELS, AND THE FACT THAT STABILITREK IS AN INTEGRAL SAFETY FEATURE OF THE VEHICLE IN AVOIDING ACCIDENTS SEEMS TO MERIT A RECALL. PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

AT AROUND 20 MILES PER HOUR, WHILE ACCELERATING, ALL TORQUE IS LOST AND THE VEHICLE ENGINE REVS HIGH. IT TAKES A FEW SECONDS, THEN THE TRANSMISSION FINALLY SHIFTS INTO THE NEXT GEAR. THIS CAUSES A BIG JOLT. IT IS DANGEROUS, ALL POWER IS LOST, THEN SUDDENLY TOO MUCH POWER IS APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE. I HAVE TAKEN IT TO THE DEALERSHIP. THEY WON'T DO ANYTHING ABOUT IT. THE VEHICLE NOW HAS 40,502 MILES.

I HAD MY 2017 GMC TERRAIN DENALI FOR TWO YEARS AND HAVE ALREADY EXPERIENCED TWO SERIOUS ISSUES. ISSUE #1-I NOTICED A BURNING SMELL, GRINDING NOISE, AND HESITATION WHEN DRIVING. I BROUGHT IT TO THE DEALERSHIP WHERE I BOUGHT IT AND WAS TOLD THAT THERE WAS A FACTORY DEFECT WHICH CAUSED SOMETHING INSIDE MY TRANSFER TO BORE A HOLE THROUGH IT. DEALER COULD NOT GET THE PART FOR 2 WEEKS. IT WAS COVERED UNDER MY WARRANTY. A MONTH LATER WHILE GETTING AN OIL CHANGE AT A DIFFERENT AUTO SHOP, I WAS ASKED IF I RECENTLY HAD WORK DONE ONLY TRANSMISSION BECAUSE THE ENTIRE THING WAS LOOSE AND MOVING, AND THE CAR DID NOT DRIVE RIGHT. I WAS TOLD IT WAS NOT SAFE TO DRIVE. I BROUGHT IT BACK TO THE DEALERSHIP AND WAS TOLD THAT THEY COULDN'T FIND ANYTHING. THEY TIGHTENED THE BOLTS ON THE TRANSFER CASE AND CHARGED ME A $60 DIAGNOSTIC FEE (FOR THEIR ERROR). ISSUE #2-AT 63,000 MILES MY WIPERS STOPPED WORKING WHILE I WAS DRIVING AT ABOUT 30MPH ON A BUSY STREET IN THE POURING RAIN (VERY SCARY). I BROUGHT IT TO THE DEALERSHIP AND WAS TOLD I NEEDED A NEW WIPER TRANSMISSION AND WOULD COST $318 BECAUSE MY CAR WAS NOT PART OF THE RECALL. I EXPRESSED CONCERN THAT MY 2YO. CAR HAS NOW HAD TWO SERIOUS SAFETY ISSUES AND WAS TOLD 'CARS HAVE SO MANY MOVING PARTS AND PIECES THAT IT'S A WONDER MORE THINGS WEREN'T WRONG WITH IT'. I DO NOT FEEL SAFE DRIVING THIS CAR AND THE SERVICE MANAGER WAS CONDESCENDING AND COULDN'T CARE LESS. GMC NEEDS TO DO SOMETHING BEFORE SOMEBODY GETS SERIOUSLY HURT OR WORSE.
