NHTSA Complaint #10679734 — 2011 FORD F-150

MY VEHICLE IS EQUIPPED WITH THE 3.5 LITER ECOBOOST 6 CYLINDER ENGINE. UPON ATTEMPTING TO PASS A VEHICLE WHILE TRAVELING AT FREEWAY SPEEDS, THE VEHICLE BEGAN TO HESITATE AND THE ENGINE FELT ROUGH. THE VEHICLE REFUSED TO ACCELERATE, CAUSING ME TO SWERVE BACK INTO THE RIGHT LANE TO AVOID BEING REAR-ENDED BY A VEHICLE TRAVELING IN THE LEFT LANE. AFTER APPROXIMATELY 30 - 60 SECONDS, THE VEHICLE WOULD ACCEPT THROTTLE AND RESUME NORMAL OPERATION. THIS PROBLEM HAS REPEATED ITSELF ON MULTIPLE OCCASIONS AND MY VEHICLE IS CURRENTLY AT THE DEALERSHIP FOR THE 7TH TIME TO REMEDY THIS PROBLEM. IN ONLY ONE INSTANCE OF THE MANY THAT I'VE HAD, I DID GET A CHECK ENGINE LIGHT ON. FORTUNATELY, THIS WAS DOCUMENTED BY THE FORD DEALERSHIP AS ONE ENTIRE BANK OF CYLINDERS MISFIRING. ADDITIONALLY, I HAVE BEEN COMPLAINING OF TRANSMISSION SHIFT ISSUES, WHERE AT SLOW (LESS THAN 10 MPH) SPEEDS, THE TRANSMISSION OFTEN 'HUNTS' BETWEEN TWO GEARS AND ONCE SELECTED, A LOUD NOISE EMANATES FROM UNDER THE VEHICLE AND CAUSES THE VEHICLE TO NOTICEABLY JERK I ONLY LEARNED OF NHTSA PE13018 ON 1/28/15. THE FIRST INCIDENT YIELDED INSTALLATION OF THE DEFLECTOR IN THE VICINITY OF THE CHARGE AIR COOLER. ANOTHER INCIDENT YIELDED A TSB TO REMOVE THE DEFLECTOR, AND MOST RECENTLY ANOTHER TSB TO RE-INSTALL SAID AIR DEFLECTOR. IN EVERY INSTANCE OF THIS PROBLEM, I'VE HAD TO EXECUTE EMERGENCY MANEUVERS TO AVOID TRAFFIC ACCIDENTS. THE SERVICE MANAGER AT MY LOCAL FORD DEALERSHIP HAS COMMENTED THAT FORD ENGINEERING HAS NO CLUE HOW TO REMEDY THIS ISSUE. MY VEHICLE CURRENTLY HAS APPROXIMATELY 75,000 MILES ON IT AND IS COVERED UNDER FORD'S EXTENDED WARRANTY. *TR
