NHTSA Complaint #10959915 — 2008 GMC ACADIA

I HAVE A 2008 ACADIA WHICH IS EQUIPPED WITH A TIMING CHAIN THAT HAS BEEN KNOWN BY GENERAL MOTORS TO PREMATURELY STRETCH AND FAIL, AND WHICH CAN CAUSE SERIOUS DAMAGE TO OTHER ENGINE COMPONENTS, AS WELL AS ACTIVATE CERTAIN SENSORS EITHER PREMATURELY OR NOT AT ALL. YOUR ENGINE AND KEY COMPONENTS AND CRANKSHAFTS AND SENSORS RELY ON THE TIMING CHAIN IN ORDER TO FUNCTION PROPERLY. WHEN YOU'RE DRIVING IN YOUR VEHICLE AND THE TIMING CHAIN GETS STRETCHED, THE CHECK ENGINE LIGHT FLASHES ON, THE ENGINE AND TRANSMISSION WILL POWER DOWN AND SHUT OFF, A LOUD BUZZING SOUND WILL OCCUR AND HOPE TO GOD YOU ARE NOT ON THE HIGHWAY, BECAUSE GENERAL MOTORS KNOWS ABOUT THE DEFECT BUT STILL WILL NOT ISSUE A RECALL ON THE PREMATURELY STRETCHED TIMING CHAINS DUE TO THE EXTENSIVE COST OF REPAIR. THEY HAVE EXTENDED WARRANTY COVERAGE ON CERTAIN SIMILAR MODELS IN 2007 AND 2009, AND HAVE OFFER FULL REPLACEMENT OF THE TIMING CHAIN UP TO 10 YEARS AND 120,000 MILES, BUT DESPITE THE SAME ISSUE OCCURRING IN VEHICLES MADE IN 2008 WITH THE SAME DEFECTS, THEY HAVE DENIED MY SERVICE REQUEST. THIS A VERY COSTLY AND EXTREMELY UNSAFE CONDITION TO DRIVE THE VEHICLE IN. IT IS TERRIFYING WHEN YOUR ENGINE MISFIRES AND POWERS DOWN, AND YOUR WARNING LIGHTS FLASH WITH A LOUD BUZZING ALARM SOUND BLARING THROUGH THE SPEAKERS. THE TRACTION CONTROL, STABILITRAK SYSTEM, AND AIRBAG SENSORS ARE ALL ADVERSELY AFFECTED BY THE DEFECTIVE TIMING CHAIN AS WELL, AND THE MANUFACTURER IS WELL AWARE OF THIS DEFECT AND UNFORTUNATELY WILL PROBABLY NOT BE HELD RESPONSIBLE UNTIL SOMEONE IS KILLED IN AN ACCIDENT AS A RESULT OF A DEFECTIVE TIMING CHAIN. I'M SO DISAPPOINTED IN THIS VEHICLE AND THE LACK OF ACCOUNTABILITY THROUGH THE MANUFACTURER. THEY KNOW IT'S A PROBLEM. THEY ARE AWARE OF THE DEFECT. THEY EVEN EXTENDED COVERAGE TO REPLACE UP UNTIL A CERTAIN POINT, BUT BEYOND THAT, THEY DO NOT CARE.
