NHTSA Complaint #10475444 — 2011 FORD F-150

UNDER HARD ACCELERATION INTO TRAFFIC OR WHEN PASSING, VEHICLE WILL SUDDENLY LOSE POWER AND GO INTO A "LIMP MODE." THIS CONDITION IS THOUGHT TO OCCUR BECAUSE OF ENGINE MISFIRE AND SEVERAL FACTORS HAVE BEEN IDENTIFIED THAT CAN CAUSE THIS IN THE ECOBOOST 3.5L V6. THE DEALER HAS REPLACED IGNITION COILS WITH NO SUCCESS IN CORRECTING THIS ISSUE. MY SERVICE MANAGER SHARED WITH ME THAT FORD ENGINEERING IS WELL AWARE OF THE ISSUE AND HAS YET TO COME UP WITH A SOLUTION TO CORRECT IT. IN THE MEANTIME, MY FAMILY IS PLACED AT RISK OF AN ACCIDENT BECAUSE THERE IS NO WAY TO PREDICT WHEN THE ENGINE WILL SUDDENLY LOSE POWER WHEN YOU NEED IT MOST FOR PASSING OR MERGING SITUATIONS. THIS BECOMES EVEN WORSE WHEN PULLING A TRAILER. NHTSA SHOULD DEMAND THAT FORD IMMEDIATELY RECALL AND REPAIR THESE VEHICLES, OR REPLACE THEM UNTIL AN APPROPRIATE SOLUTION IS FOUND TO REMEDY THE MISFIRE CONDITION AND RESULTANT LOST OF POWER. *TR
