NHTSA Complaint #10502249 — 2013 FORD F-150

I WAS TRAVELING AT EXACTLY 70 MPH ON THE INTERSTATE AT ABOUT 40 DEGREES IN MY BRAND NEW 2013 F-150 ECOBOOST. WHILE ATTEMPTING TO PASS A LINE OF SLOWER SEMI-TRUCKS, I PUT THE ACCELERATOR PEDAL TO THE FLOOR. THE ENGINE REV'D AND THE STARTED VIOLENTLY SHUTTERING TO THE POINT I THOUGHT THE ENGINE MOUNTS WERE SURELY BREAKING. THE VEHICLE LOST MOST OF ITS POWER AND WITH ANOTHER TRUCKER BEHIND ME IN THE PASSING LANE, IT IMMEDIATELY BECAME AN EXTREMELY DANGEROUS SITUATION. I COULD NOT ACCELERATE AT ALL AND FORTUNATELY WAS ABLE TO LET THE LOWER TRAFFIC PASS ME SO I COULD FALL INTO THE SLOW LANE -- IT WAS VERY DANGEROUS TO PUT IT MILDLY. THE TRUCK FIXED ITSELF AFTER ABOUT 5 MILES OF SLOWER DRIVING. I TOOK IT TO THE FORD DEALERSHIP THE NEXT MORNING AND THEY KEPT IT FOR SEVERAL DAYS AND COULDN'T FIND ANY PROBLEMS. I TRIED TO DUPLICATE THE EVENT AND COULDN'T. THE SCENE REPEATED ITSELF THREE TIMES UNDER EXACTLY THE SAME CIRCUMSTANCES WITH TWO OR THREE WEEKS SEPARATING THE OCCURRENCES. THE LAST TIME THE DEALERSHIP SERVICE DEPARTMENT SAID FORD CORPORATE ENGINEERING DID NOT KNOW WHAT THE PROBLEM WAS AND TO TRY RE-INSTALLING THE COMPUTER SOFTWARE. THIS APPEARS TO HAVE FIXED THE PROBLEM BUT MY GAS MILEAGE HAS GONE DOWN TO AN AVERAGE 18.5 MPG AND PREVIOUSLY I WAS GETTING UP TO 25 MPG AVERAGE. *TR
