NHTSA Complaint #11319618 — 2015 GMC DENALI

HAVE HAD MY VEHICLE AT THE SHOP FOR TRANSMISSION ISSUES SEVERAL TIMES. TWO OF THE TIMES, ISSUES WERE DUPLICATED AND PARTS REPLACED, BUT SAME ISSUES CONTINUE AS SOON AS I GET IT BACK. MY COMPLAINT WHEN I TAKE IT IN IS ALWAYS THE SAME. NORMALLY WHEN I ACCELERATE FROM A DEAD STOP FORWARD OR REVERSE, THE TRANSMISSION MAKES A THUMPING NOISE. IT HAS STEADILY GOTTEN WORSE. A LOT OF TIMES NOW IF I TAKE MY FOOT OFF GAS FOR A SECOND, AT FASTER SPEEDS, AND THEN PUT FOOT RIGHT BACK ON GAS, IT MAKES THE SAME THUMPING NOISE AND SOMETIMES A GRINDING NOISE LIKE IT'S STUCK BETWEEN GEARS. THIS LAST TIME I TOOK IT TO THE DEALER, WAS TOLD THERE WAS NOTHING THEY COULD DO AND WOULD MOST LIKELY GET WORSE AS VEHICLE GETS OLDER.
