NHTSA Complaint #10564838 — 2011 GMC TERRAIN

THE SAME ISSUE HAPPENED 3 TIMES. NOVEMBER 2013, 28 JANUARY 2014, 16 FEBRUARY 2014. EACH TIME THE VEHICLE WAS IN AND IDLING SITUATION RED LIGHT, IN A FAST FOOD DRIVE THRU, HEAVY TRAFFIC, OR IF I FORGOT SOMETHING, LEFT THE CAR RUNNING, AND WENT INTO THE HOUSE TO GET WHAT I WAS LOOKING FOR, ESPECIALLY IF IT TOOK ME 4-5 MINUTES TO FIND WHAT I WAS LOOKING FOR AND RETURN TO THE CAR. ADDITIONALLY, I'VE EXPERIENCED THIS MOVING AT SPEEDS OF 8MPH OR LESS IN THICK TRAFFIC. (1) CAR WOULD FOR NO REASON START ROUGH IDLING. (2) THE YELLOW CHECK ENGINE LIGHT WOULD COME ON. (3) THE ENGINE REDUCED POWER MESSAGE WOULD APPEAR. (4) THE STABILITRAK WARNING MESSAGE LIGHT WOULD THEN APPEAR. (5) THEN I PRESSED THE ACCELERATOR TO CROSS AN INTERSECTION AND MOVE OUT OF THE WAY OF TRAFFIC, AND THE VEHICLE MOVES AT A SNAIL'S PACE (5-10 MPH). (6) I LET IT SIT FOR 10-30 MINUTES (OR OVERNIGHT IF I WAS FORTUNATE ENOUGH TO BE AT HOME), RESTART IT, AND IT RUNS LIKE IT NORMALLY DOES AS IF NOTHING EVER HAPPENED. (7) THE "YELLOW CHECK ENGINE LIGHT" SIMPLY DISAPPEARS AFTER A FEW HOURS. (8) SOMETIMES THERE'S A FAINT BURNING SMELL LIKE A PLASTIC GARBAGE BAG ON FIRE, BURNING RUBBER, OR OVERHEATED ELECTRONICS. I'M TAKING IT TO MY LOCAL GMC DEALERSHIP TODAY BEFORE I END UP STRANDED SOMEWHERE OR WORSE BE THE CAUSE OF A MAJOR SERIOUS ACCIDENT! IT'S LIKE IT HAS A MALICIOUS CODE IN THE ENGINE'S COMPUTER SYSTEM, AND IT SELECTS THE TIME AND PLACE WHEN IDLING TO INJECT ITSELF! IT MAY GO SEVERAL WEEKS OR EVEN MONTHS BEFORE IT HAPPENS, BUT YOU CAN BE CONFIDENT IT'S GOING TO HAPPEN! OTHER THAN THIS ANNOYING SAFETY ISSUE, THE TERRAIN IN MY OPINION IS A PRETTY GOOD VEHICLE FOR ITS CLASS. MAKES ME WISH I HAD CHOSEN THE 6 CYLINDER INSTEAD OF THE 4 CYLINDER. I DON'T THINK THE 6 CYLINDER IS HAVING THIS ISSUE. GM/GMC SHOULD ADDRESS THIS, AND MAKE THIS RIGHT ASAP! *TR
