NHTSA Complaint #10567146 — 2008 BUICK ENCLAVE

WHILE ACCELERATING FROM A STOP THROUGH AN INTERSECTION, THE TRANSMISSION FAILED AND THE VEHICLE COASTED TO A STOP BLOCKING TRAFFIC. AFTER TURNING THE KEY OFF AND THEN STARTING THE CAR, MY WIFE WAS ABLE TO GET THE CAR TO MOVE AT A CRAWL 15FT AT A TIME. AFTER DOING THIS SEVERAL TIMES SHE WAS ABLE TO PARK THE CAR SAFELY OFF OF THE ROAD. WE HAD THE VEHICLE TOWED TO THE GM DEALERSHIP AND THEY DIAGNOSED THE PROBLEM AS A R, 3,5 WAVE PLATE FAILURE. THE DEALERSHIP HAS RECOMMENDED A NEW TRANSMISSION AT A COST OF $4,400. AFTER SOME RESEARCH I HAVE FOUND THIS TO BE A COMMON PROBLEM WITH THE 6T75 TRANSMISSION ACROSS THE ENTIRE GM LINE OF VEHICLES MANUFACTURED IN LATE 2007. THERE IS A SERVICE BULLETIN (09-07-30-012B) THAT ADDRESSES THIS, BUT NO RECALLS YET. *TR
