NHTSA Complaint #10909466 — 2012 FORD F-150

LOSS OF POWER UNDER HARD ACCELERATION, UNDIAGNOSED MISFIRE AT ALL SPEEDS. THESE PROBLEMS OCCUR IN DRY AND WET CONDITIONS. THE TRUCK LOST POWER ON THE INTERSTATE TWICE AND I HAD TO PULL OVER AND SHUT IT DOWN THEN RESTART TO CONTINUE (AROUND 20K MILES). THIS OCCURRED WHILE UNDER WARRANTY, DEALER SAID THEY COULDN'T DO ANYTHING BECAUSE THERE WAS NO SEL ACTIVATED. AS MILEAGE HAD INCREASED, MISFIRE ARE WORSENING EVEN AFTER WATER IS REMOVED FROM AIR COOLER AND SPARK PLUGS REPLACED. MY TRUCK WAS AT A DEALER FOR 3 DAYS AND THEY TOLD ME THEY DID NOT KNOW WHAT WAS WRONG. NORMALLY CHANGING THE PLUGS AND CLEANING OUT THE AIR COOLER FIXES THE PROBLEMS FOR A WHILE UNTIL NOW. I HAVE EVEN REPLACED A COIL BECAUSE IT IS THROWING A CODE FOR #1 CYLINDER NOT FIRING. THE NEW COIL MADE NO DIFFERENCE. THE VEHICLE HAS 133,000 MILES AND IS ALMOST NOT DRIVABLE IT HAS GOTTEN SO BAD. I HAVE SUBMITTED MY COMPLAINT TO FORD CUSTOMER SERVICE AS WELL.
