NHTSA Complaint #10743752 — 2011 FORD F-150

WHEN ACCELERATING AND APPROACHING FREEWAY SPEED, ENGINE STUMBLED, PREVENTING ACCELERATION. I LET OFF THE ACCELERATOR AND PROBLEM DIDN'T OCCUR AGAIN. I REPORTED THIS TO THE DEALER, BUT THEY STATED THAT SINCE THE VEHICLE DID NOT REGISTER A CODE THERE WAS NOTHING THEY COULD DO. I HAVE SINCE HAD THIS HAPPEN AGAIN ON JULY 17 & 18, 2015, BUT THIS TIME THE ENGINE LIGHT DID COME ON, SO I'M ASSUMING IT DID REGISTER A CODE. ON JULY 17, IT WAS A CLEAR DRY DAY, THE FOLLOWING DAY IT HAPPENED AGAIN, BUT IT WAS RAINING ALL DAY. ONCE ON THE FREEWAY, WHENEVER I STEPPED ON THE ACCELERATOR, EVEN WHEN AT FREEWAY SPEED, THE ENGINE WOULD STUMBLE AND BARELY ACCELERATE. I'VE CONTACTED THE DEALER AND SCHEDULED AN INSPECTION FOR JULY 29, 2015. THE VEHICLE CURRENTLY HAS 47000 MILES. I'VE TALKED TO FORD CUSTOMER SERVICE AND I AM BEING TOLD THIS IS NOT A WARRANTY REPAIR, BUT I AM SEEING A NUMBER OF SERVICE BULLETINS BEING ISSUED DESCRIBING THIS EXACT PROBLEM. I BELIEVE THIS IS A DEFECT IN DESIGN AND SHOULD BE COVERED UNDER THE MANUFACTURERS WARRANTY.
