NHTSA Complaint #10870199 — 2014 GMC TERRAIN

IN OCTOBER 2015, I WAS DRIVING ON THE INTERSTATE IN A RURAL AREA, AND ACCELERATED TO PASS ANOTHER VEHICLE. MY PASSING SPEED WAS APPROXIMATELY 80 MPH. I MERGED BACK INTO THE RIGHT LANE AFTER PASSING, AND LET MY FOOT OFF THE GAS. CRUISE CONTROL WAS NOT ENGAGED. THE CAR CONTINUED AT THE PASSING SPEED, AND STARTED TO INCREASE IN SPEED. I WAITED A FEW SECONDS TO SEE WHAT WOULD HAPPEN BEFORE TAKING EVASIVE ACTION; AS THERE WERE NO OTHER CARS ON THE HIGHWAY AT THIS POINT. FOR 4-5 SECONDS THIS CONTINUED. I TAPPED THE BRAKE AND NO CHANGE WAS DETECTED. I THEN TAPPED THE ACCELERATOR PEDAL; AND THE SPEED DISENGAGED. VEHICLE WAS TAKEN TO DEALER; DIAGNOSTIC WAS RUN AND THEY COULD NOT DETECT A PROBLEM. DEALER WAS OF THE OPINION THAT THIS EVENT HAD SOMETHING TO DO WITH THE DRIVE TRAIN, THEY DROVE THE CAR BUT WERE UNABLE TO DUPLICATE THE PROBLEM. THIS ALL SEEMED TO INDICATE THAT CRUISE CONTROL WAS ON; HOWEVER I AM SURE IT WAS NOT.
