NHTSA Complaint #10630144 — 2012 FORD F-150

WHILE TRAVELING AT INTERSTATE SPEED OF APPROX. 70 MPH, I ATTEMPTED TO PASS A SLOWER VEHICLE GOING UP A SLIGHT HILL. THERE WAS A SHUDDER AND THEN THE VEHICLE LOST ENGINE SPEED. I WENT FROM 70 MPH TO 55 MPH WITHOUT THE ABILITY TO MAINTAIN ANY SPEED, I WAS NOT APPLYING THE BRAKES. I COULD NOT COMPLETE THE PASS AND HAD TO PULL OVER TO THE SIDE OF THE ROAD. IF I TRIED TO MAINTAIN SPEED OR ACCELERATE THE VEHICLE SHOOK VIOLENTLY, WAKING UP MY FAMILY. THE CHECK ENGINE LIGHT CAME ON AND JUST FLASHED. I PULLED FROM THE DRIVING LANE AND RESTARTED THE VEHICLE. THE LIGHT WENT OFF AND I WAS ABLE TO CONTINUE THE DRIVE, HAD TO BE VERY MINDFUL OF MY ACCELERATION. IT HAPPENED A SECOND TIME THE NEXT MORNING, AGAIN PASSING; SHUDDER AND THEN AN INABILITY TO MAINTAIN SPEED OR INCREASE IT. I PULLED OVER THIS TIME THE LIGHT CAME ON AND STAYED ON. I WILL BE TAKING IT TO A DEALER THIS WEEK. I WAS TRAVELING FOR APPROX. TWO HOURS PRIOR TO THE FIRST EVENT. IT WAS RAINING DURING THE FIRST EVENT, THE SECOND EVENT IT WAS PARTLY CLOUDY. *TR
