NHTSA Complaint #10663104 — 2014 GMC ACADIA

I WAS TRAVELING ON THE HIGHWAY AT ABOUT 70 MPH IN THE LEFT LANE AND THE ENGINE BEGAN TO SPUTTER LIKE IT WAS GOING TO STALL. IT DROPPED MY SPEED TO 60 WITHOUT WARNING. I HAD A VEHICLE BEHIND ME GOING THE SAME SPEED AND HAD TO QUICKLY MOVE TO THE RIGHT TO AVOID GETTING HIT. THE CHECK ENGINE LIGHT CAME ON AND THE TRACTION CONTROL / STABILITRAC TURNED OFF. BROUGHT IT TO THE DEALER AND THEY TOLD ME I WAS USING THE WRONG GAS. THEY CLEANED CARBON OUT OF THE INTAKE VALVES. I HAVE PUT GAS IN IT TWICE SINCE THEN, AT SHELL, WHICH IS WHAT THEY TOLD ME TO USE. IT HAPPENED AGAIN TODAY 12/9 WHEN I WAS GOING AROUND A CORNER IN THE RAIN. THIS TIME IT SAID SERVICE STABILITRAK AND SERVICE TRACTION CONTROL WITH THE CHECK ENGINE LIGHT FLASHING AND THE ENGINE SPUTTERING. I HAD BEEN GOING THROUGH A PUDDLE AT THE TIME SO I ALMOST LOST CONTROL OF THE VEHICLE. CALLED THE DEALER AND THEY TOLD ME THEY HAD NO RECORD OF ME BRINGING IT IN ON THE 21ST. I AM BRINGING IT BACK TO THEM ON THE 15TH BECAUSE THAT IS THE FIRST TIME THEY WILL HAVE A LOANER AVAILABLE FOR ME. I AM NOW AFRAID TO DRIVE MY CAR BECAUSE OF THE DANGER OF SLIDING AND LOSING CONTROL. I HAVE NO WARNING OF WHEN THIS IS GOING TO HAPPEN AND I HAVE NOT BEEN ABLE TO PIN POINT IT HAPPENING AT ANY CERTAIN MILEAGE OR SUCH. VERY SCARY WHEN IT HAPPENS. *TR
