NHTSA Complaint #11153179 — 2012 GMC TERRAIN

I ALSO HAVE A 2012 GMC TERRAIN THAT HAS AN OIL CONSUMPTION ISSUE THAT HAS CAUSED COMPLETE ENGINE FAILURE. APPROXIMATELY 2.5 WEEKS AGO THE CAR WOULDNT START. ENGINE WOULD TURN OVER BUT NOT START. I THOUGHT THAT IT MIGHT BE THE FUEL PUMP. HAD IT TOWED TO MY MECHANIC SINCE IT HAS 87K MILES AND OUT OF WARRANTY. SO I WENT TO CHECK THE STATUS OF THE CAR AND THE FIRST THING I WAS TOLD WAS THERE WAS NO OIL WHEN THEY CHECKED IT. THEY ADDED 4 QUARTS BEFORE TRYING TO DIAGNOSE THE PROBLEM. MIND YOU THE OIL WAS CHANGED 3K MILES AGO AND OIL LIFE MONITOR SAID IT HAD 54% LIFE LEFT. THEY RAN THE CAR FOR CODES AND THE ONLY CODE THAT CAME UP WAS FOR THE TIRE PRESSURE SYSTEM, ALSO AN ISSUE WITH THE TERRAIN. NO ISSUE WAS FOUND WITH FUEL PUMP OR SENSORS. SPARK PLUGS WERE REPLACED DUE TO THEM BEING ALL FOULED UP. THAT DIDNT FIX THE ISSUE SO IT WAS DETERMINED THAT IT MUST BE THE TIMING CHAIN JUMPED. AT THAT POINT I HAD IT TOWED AGAIN TO THE DEALERSHIP I PURCHASE IT FROM. I WAS TOLD IT WOULD BE 125.00 TO RUN A DIAGNOSTIC. FINE. SO I GET A CALL THE NEXT DAY THAT IT WAS INDEED THE TIMING CHAIN. I ASKED THE SERVICE GUY WHAT WOULD CAUSE THIS AND I WAS TOLD POOR LUBRICATION OR LOW OIL PRESSURE. THATS WHEN I STARTED TO EXPLAIN THAT THE FIRST SHOP HAD TO PUT 4QTS OF OIL IN BC IT WAS BONE DRY. I ASKED ABOUT THE VIN SPECIFIC LETTER I RECEIVED LAST YEAR,2017, ABOUT THE OIL CONSUMPTION ISSUE AND ISNT THAT WHY THERE WAS NO OIL AND HENCE CAUSING THE TIMING BELT TO JUMP. HE ANSWERED "NO". THEN TOLD THAT UPON FURTHER INSPECTION, THE VALVES WERE BENT SO WE WERE NOW LOOKING AT 3500 TO FIX OR 6K TO REPLACE THE ENGINE WITH ANOTHER PROBLEMED ENGINE. SO THAT IS WHEN I CONTACTED THE TOLL FREE CUSTOMER SERVICE LINE ABOUT THE SITUATION. THEY TOLD ME TO GO BACK TO DEALERSHIP AND SPEAK TO THE CUSTOMER EXPERIENCE MANAGER.
