NHTSA Complaint #11082339 — 2013 GMC TERRAIN

CAR MAKES TERRIBLE ENGINE NOISE WHEN STARTING/AS IT IDLES. THIS IS ALMOST ALWAYS DUE TO LOW OIL.THIS CAR BURNS THROUGH OIL FASTER THAN ANYTHING IVE EVER SEEN. EVEN WITH FULL SYNTHETIC OIL I HAVE TO ADD AT LEAST QUART EVERY 700 MILES FOR SO. KEEPING THE OIL LEVEL UP HELPS OBV, HOWEVER THIS PROBLEM WAS GOING ON FOR SOME TIME BEFORE I FIGURED OUT THE CAR WAS CONSUMING OIL AT A SUPER FAST RATE. SO WHO KNOWS WHAT DAMAGE MAY BE INSIDE THE ENGINE AT THIS POINT. IT HAS BEEN REPORTED THAT THERE IS AN ISSUE WITH THE TIMING CHAIN ON THE I4 ENGINES AND THEY BURN OIL BECAUSE THE TIMING IS OFF. HOWEVER GM'S ONLY FIX THUS FAR IS TO RUN AN OIL STUDY WHICH TAKES UP A LOT OF TIME.THIS IS ALSO HUGE PAIN WHEN DEALING WITH ANY DEALER, BECAUSE ONLY A GM DEALER CAN RUN THE TEST, AND EVEN IF IT IS FOUND THAT YOUR CAR IS BURNING OIL THEY WILL DETERMINE IT AS "NORMAL" IF IT'S NOT A SPECIFIC RATE. THERE'S NO WAY FULL SYNTHETIC SHOULD BE BURNING UP THIS QUICKLY. GM NEEDS TO DO A RECALL FOR THIS ISSUE BUT WILL NOT BECAUSE ONCE THEY TRULY FIX THE ISSUE IT WILL OPEN UP A CAN OF WORMS THAT WOULD COST THEM THOUSANDS. SO INSTEAD THE COST IS PASSED ON TO THE OWNER. IF THEY DO OFFER A FIX AFTER THE OIL STUDY IT'S ONLY FOR A PISTON RING KIT WHICH DOES NOT ACTUALLY FIX THE PROBLEM OF THE BAD TIMING CHAIN. SO FAR THE ONLY RELIEF I HAVE FOUND IS TO TURN THE ECO MODE OFF. THIS GIVES A LITTLE RELIEF TO THE CONSTANT FILLING OF OIL. OTHER THAN THAT IF THE CAR IS LOW ON OIL YOU WILL FEEL A CHUGGING/ JERKING OF THE CAR, PARTICULARLY AT A STOP OR LOW IDLE. I LOVE THE LOOK OF GMC'S HOWEVER I DON'T THINK I CAN EVER BUY ONE AGAIN AFTER DEALING WITH AN ISSUE LIKE THIS AND HAVING GM NOT RECALL A WIDELY KNOW ISSUE.
