NHTSA Complaint #11280374 — 2013 GMC TERRAIN

THE CAR STARTED TO "BUCK" AND MAKING A TAP TAP TAP NOISE LIKE A LIFTER TAPPING WHILE DRIVING TO WORK. WHEN I GOT OUT OF THE VEHICLE, SOMETHING SMELLED HOT. CHECKED UNDER THE HOOD AND THERE WAS NOTHING WET OR STEAMING. NO CHECK LIGHTS EVER CAME ON. LATER AT LUNCH, I LEFT AND THE TAPPING NOISE WAS LOUDER AND THE HEAT GAUGE INCREASED FAST. I STOPPED AT A REPAIR SHOP. WHILE I WAITED I CHECKED THE OIL. THERE WASN"T ANY!!! AT ALL. THE DIPSTICK WAS MILKEY. THE OIL FILL CAP WAS WET INSIDE AND MILKEY. UNDERNEATH MY CAR WAS COVERED IN FRESH OIL. IT WAS DETERMINED TO BE A BUSTED REAR MAIN SEAL. 4 QTS OF OIL ADDED SO I COULD GET HOME. MY MECHANIC CONFIRMED THE DIAGNOSIS. HE WAS SHOCKED. HE FOUND GM BULLETIN 14882 ONLINE. WHAT IS DESCRIBED IN THAT VIDEO IS EXACTLY WHAT HAPPENED. WE HAD A SUDDEN HARD FREEZE X 3 DAYS. THE PVS CONNECTION AT THE INTAKE WAS FULL OF WATER. WHEN THAT FROZE, IT BLEW OUT THE SEAL. MY CAR HAS 88,000 MILES ON IT. THERE ARE VIDEOS AFTER VIDEOS ONLINE OF THE SAME ENGINE DOING THIS EXACT SAME THING. I CALLED GM. THE BEST THEY COULD DO IS TELL ME TO REPORT TO YOU.
