NHTSA Complaint #10839925 — 2009 GMC ACADIA

GMC KNOWS OF DEFECTIVE TIMING CHAINS IN THIS MAKE AND MODEL. THEY ADDRESSED SOME OF THESE ISSUES IN TSBS AND THE INFORMATION WAS KNOWN BY DEALERS BUT NEVER CONVEYED TO OWNERS THAT DID NOT RECEIVE A TSB. THE DEALERSHIP PERFORMED NUMEROUS OIL CHANGES, WHICH IF INCREASED IN FREQUENCY AND MORE CLOSELY MONITORED, COULD HAVE BEEN PART OF THE FIX, BUT THE DEALERSHIP NEVER INFORMED THE OWNER OF POTENTIAL CATASTROPHIC CONSEQUENCES OF NOT INCREASING OIL CHANGE FREQUENCY. ACCORDING TO DEALER, GM FORBIDS THEM FROM DISCLOSING SUCH INFORMATION. THESE ENGINES WERE ALSO EQUIPPED WITH A PRESSED ON CRANKSHAFT RELUCTOR THAT COULD SHIFT AND RESULT IN A TOTAL CRANKSHAFT REPLACEMENT. FAILURE OF ANY OF THESE VITAL ENGINE PARTS ALONE OR TOGETHER WHILE THE VEHICLE WAS IN MOTION COULD, I BELIEVE, CAUSE AN ENGINE SEIZURE WHICH COULD POTENTIALLY LEAD TO DEVASTATING CONSEQUENCES. NON DISCLOSURE BY DEALERS TO ALERT OWNERS WHO COULD THEN DIVEST THEMSELVES OF THESE VEHICLES BEFORE THE 120K DEADLINE SET BY GM IS DISHONEST AT BEST. NO TSBS RELATING TO THIS WERE RECEIVED BY OWNER. THERE IS NOW AN ENGINE WARNING LIGHT CONCERNING THE TIMING CHAIN AND POSSIBLE RELUCTOR BUT GM IS UNWILLING TO ASSIST WITH REPAIRS SINCE THE VEHICLE IS ABOUT 15K BEYOND THEIR ARBITRARY 120K DEADLINE.
