NHTSA Complaint #10512773 — 2012 FORD F-150

I WAS DRIVING ON A 2 LANE HIGHWAY, BEHIND A SEMI TRUCK, WITH SEVERAL CARS BEHIND ME. WE CAME TO A PASSING ZONE AND I BEGAN TO PASS THE SEMI TRUCK. I MOVED TO THE ONCOMING LANE AND ACCELERATED, BUT THE TRUCK LOST POWER. I BEGAN SLOWING DOWN IN THE ON COMING LANE, BUT COULDN'T RETURN TO THE RIGHT LANE BECAUSE THE VEHICLES THAT WERE BEHIND ME WERE PASSING ME IN THE RIGHT LANE AND I HAD A VEHICLE DIRECTLY BEHIND ME THAT WAS FOLLOWED ME TO PASS THE SEMI TRUCK. I LOCKED OUT 5TH AND 6TH GEARS ON THE TRANSMISSION TO GAIN SOME RPM BUT THE VEHICLE STARTED TO SHUDDER VIOLENTLY. I MOVED TO THE SHOULDER OF THE ON COMING LANE AND SHUT THE VEHICLE OFF. I SAT ON THE SHOULDER FOR SEVERAL MINUTES, GOT OUT OF THE VEHICLE AND CHECKED UNDER IT FOR FLUIDS. THERE WERE NO FLUIDS UNDER THE VEHICLE. ALL THE GAUGES READ NORMAL. I DID ALL THIS ON THE SHOULDER OF THE ONCOMING LANE FACING ONCOMING TRAFFIC. THIS WAS NOT A GOOD POSITION TO BE IN. I STARTED THE VEHICLE, PUT IT IN GEAR TO SEE IF IT WOULD MOVE, IT DID. I HAD FULL POWER AND GOT BACK INTO TRAFFIC AND THE TRUCK RAN FINE. NO WARNING LIGHTS, NO INDICATION THAT ANYTHING WAS WRONG. SEVERAL MILES LATER I LOST ENGINE POWER AGAIN, AND AGAIN GOT THE VIOLENT SHUDDER, AND THE CHECK ENGINE LIGHT CAME ON. GOING TO SEE THE DEALER TODAY. THIS IS BAD! THE FIRST INCIDENT COULD HAVE CAUSED A HUGE ACCIDENT. MOVING ONTO THAT LEFT SHOULDER PROVED TO BE A GOOD MOVE, BUT I WAS AT PUCKER FACTOR 10 FOR A FEW SECONDS. *TR
