NHTSA Complaint #10949594 — 2015 FORD F-150

THE FIRST TIME I NOTICED THE PROBLEM WAS WHEN I WENT TO PASS ANOTHER VEHICLE. I DID A HARD ACCELERATION TO PASS AND MY 2015 F150 3.5 ECOBOOST ENGINE STALLED IN THE PASSING LANE ON A 2 LANE HIGHWAY. I WAS DOING 45 MPH. I IMMEDIATELY GOT BACK INTO MY LANE BEHIND THE VEHICLE I WAS PASSING. AFTER THAT INCIDENT I HAVE OCCASIONALLY ACCELERATED HARD TO SEE IF THE ENGINE WOULD STALL. SOMETIMES IT WOULD STALL AND SOMETIMES IT WOULD NOT. I TOOK IT BACK TO THE FORD DEALER AND THEY REPLACED THE THROTTLE PACK BUT IT STILL STALLS. THEY ARE AT A LOSS ON WHAT IS CAUSING THIS ERRATIC ACCELERATION PROBLEM. THEY SAY THEY HAVE NOT HAD ANY SERVICE BULLETINS FROM FORD RELATING TO THIS. THIS HAPPENED NOT LONG AFTER I PURCHASED THE VEHICLE WITH LESS THAN 2000 MILES ON IT. I NOW HAVE 18000 MILES ON IT AND THIS PROBLEM HAS BEEN ONGOING SINCE I BOUGHT IT. THE DEALER AND I HAVE BEEN WAITING TO SEE IF FORD WILL OFFER A SOLUTION BUT SO FAR THEY HAVE DONE NOTHING.
