NHTSA Complaint #10651888 — 2007 GMC ACADIA

OUR 2007 GMC ACADIA BEGAN SLIPPING AND STUTTER STEPPING IN REVERSE. IF ON A HILL IT WAS VERY NOTICEABLE AND FELT LIKE YOU WERE SLIPPING ON ICE BEFORE REVERSE GEAR WOULD ENGAGE. THEN ON SLOW ACCELERATION FORM A TRAFFIC LIGHT SLIPPAGE WOULD OCCUR AND A ROUGH CHANGE IN THE GEAR EXCHANGE FOR NORMAL TRAFFIC SPEED. HAD IT DIAGNOSED AT A REPUTABLE LOCAL REPAIR SHOP AND THEY SAID IT WAS A WARPED WAVE PLATE AND A NEW OR REBUILT TRANSMISSION WAS REQUIRED, THE REPAIR COST WITH WARRANTY WOULD BE 4,225.00. WE TOOK IT TO THE DEALER WHERE WE PURCHASED THE ACADIA. THEY ALSO DIAGNOSED IT AS A DEFECTIVE WAVE PLATE, RECOMMENDING A NEW TRANSMISSION OR AT LEAST TO REBUILD IT. NEW TRANSMISSION TO COST 5,890.00 THE WAVE PLATE ON THE 2007 ACADIA'SHAVE CAUSED A GREAT MANY PROBLEMS FOR OTHER OWNERS AND ITS REPORTED THEY WERE NOT PROPERLY HEAT TREATED WHEN MANUFACTURED. THEY BREAK APART AFTER JUST SO MANY ENGAGES CAUSED WHEN SHIFTING AND ALMOST ALWAYS SHORTLY AFTER THE 50,000 MILE WARRANTY. FILED A COMPLAINT WITH GM REQUESTING ASSISTANCE WITH REPAIRS DUE TO A FAULTY PART THEY SHOULD HAVE BEEN AWARE OF. THEY SAID THEY WOULD GET BACK TO ME, BUT NEVER DID. WE REPAIRED IT AT THE LOCAL REPAIR SHOP COSTING 4,225.23 CENTS WITH A 5 YEAR 100,000 MILE WARRANTY. *TR
