NHTSA Complaint #10354451 — 2007 GMC ACADIA

DRIVING MY 2007 GMC ACADIA. WENT TO PASS A SLOWER VEHICLE, PRESSED ON THE ACCELERATOR TO PASS AND THE TRANSMISSION WENT HAYWIRE AND THE ACCELERATOR STUCK. I HAD TO PUT THE CAR IN NEUTRAL TO GET IT STOPPED. THE RPMS WERE IN THE 4000S. THEN THE ACCELERATION WOULD STOP AND START AGAIN OVER TO 4000. LUCKILY WHEN I PASSED THE VEHICLE THERE WERE NO CARS IN FRONT OF ME OR I WOULD HAVE HAD A MAJOR ACCIDENT WITH THE ACCELERATION OUT OF CONTROL. I TOOK IT TO THE DEALER AND THEY TOLD ME THAT TWO OF THE TIMING CHAINS WERE VERY WORN AND THERE WAS AN ISSUE WITH THE CLUTCH PRESSURE CONTROL WITH HARSH SHIFTS IN DRIVE RANGE 3RD AND/OR 5TH GEAR. THIS IS THE SECOND TIME I HAVE HAD PROBLEMS WITH THIS ISSUE. THE FIRST TIME THE GMC DEALER 'FLASHED' (REPROGRAMMED) THE TRANSMISSION, EVEN THOUGH IT WAS NOT ACTING UP WHEN THE CAR WAS TAKEN INTO THE SHOP. IF THIS ISSUE IS NOT ADDRESSED "PROPERLY", I BELIEVE SOMEONE SOMEWHERE WILL BE INJURED OR KILLED. THE CONDITION MY VEHICLE EXHIBITED LEAVES ME WITH A VERY UNEASY FEELING. *TR
