NHTSA Complaint #10872939 — 2013 FORD F-150

VEHICLE RUNS GREAT MOST OF THE TIME, BUT WHEN DRIVING AT HIGHWAY SPEEDS FOR A COUPLE OF HOURS IN THE RAIN, SNOW, HUMID OR MISTING CONDITIONS, THE TRUCK WILL SOMETIMES LOOSE POWER AND START SHAKING/STUTTERING WHEN ACCELERATING TO PASS ANOTHER VEHICLE, OR WHEN CLIMBING A HILL. MOST OF TIME, IT IS A VERY SLIGHT SHUDDER BUT WHEN UNDER HEAVY THROTTLE, THE ENGINE WILL START CUTTING OUT, LOOSE POWER AND SPEED, AND THE CHECK ENGINE LIGHT WILL START FLASHING. WHEN THIS HAPPENS, I WILL HAVE TO PULL OVER TO THE SLOWER LANE OF TRAFFIC, OR ONTO THE SHOULDER. AFTER ABOUT 30 SECONDS THE CHECK ENGINE LIGHT WILL EITHER GO OUT, OR COME ON SOLID. IT IS VERY FRIGHTENING WHEN THIS HAPPENS BUT IT HAS HAPPENED ENOUGH TIMES THAT I ALMOST EXPECT IT WHEN THE CONDITIONS ARE RIGHT FOR IT TO OCCUR. I HAVE TAKEN IT INTO VARIOUS FORD DEALERSHIPS AS I AM USUALLY OUT OF TOWN ON VACATION WHEN IT HAPPENS. THEY HAVE APPLIED ALL THE TSB'S RECOMMENDED BY FORD MOTOR, BUT OBVIOSITY THEY CAN'T RECREATE THE ISSUE ON DEMAND AND APPARENTLY CAN'T CORRECT IT. THIS IS A VERY DANGEROUS ISSUE AND I WOULD SUPPORT A TOTAL RECALL OF ALL ECOBOOST VEHICLES UNTIL CORRECTED.
