NHTSA Complaint #11257595 — 2015 FORD F-150

WHILE ACCELERATING THE VEHICLE TO GET TO 55 MPH THE ENGINE SUDDENLY LOST THROTTLE RESPONSE AND BEGAN TO RUN ROUGH. SIMULTANEOUSLY THE DASH FLASHED THAT UPHILL ASSIST WAS DEACTIVATED AND FLASHED THE MAINTENANCE WRENCH. UPON PULLING THE VEHICLE OVER AND SHUTTING IT OFF AND RESTARTING IT THE VEHICLE RAN NORMALLY. THE FREQUENCY OF THIS INCREASED FROM ONCE EVERY COUPLE OF WEEKS TO NOW UP TO 5 TIMES IN 10 MILES. WHEN IT CAUSES AN OBD CODE IT IS P2112. IT OCCURS MOST FREQUENTLY WHILE ACCELERATING TO HIGHWAY SPEEDS BUT HAS ALSO OCCURRED WHILE AT HIGHWAY SPEED AND ACCELERATING TO VILLAGE SPEEDS OF 30 MPH. IT HAS EVEN OCCURRED ONCE WHILE USING CRUISE CONTROL AS THE VEHICLE WAS CLIMBING A HILL. AT THIS TIME IT IS UNKNOWN WHAT IS CAUSING THE FAULT. AN ATTEMPT HAS BEEN MADE TO CLEAN THE THROTTLE BODY AND THE PROBLEM PERSISTS. A NEW THROTTLE BODY IS ON ORDER BUT HAS TO BE INSTALLED YET TO SEE IF IT CORRECTS THE ISSUE.
