NHTSA Complaint #11186892 — 2018 FORD F-150

AFTER A PERIOD OF TOWING A 5200# TRAILER THE 2.7L ECOBOOST ENGINE WOULD STALL WHEN NOT THROTTLING. MEANING, ANYTIME SLOWING DOWN OR STOPPING THE ENGINE WOULD CUT OFF UNEXPECTEDLY, FORCING A MANUAL RESTART. THE TRUCK DID RESTART IF THE THROTTLE WAS HELD IN PUSHING GAS AND THEN THROWING THE TRUCK INTO DRIVE GEAR TO MOVE, HOWEVER THE THROTTLE WOULD HAVE TO CONTINUE TO BE PUSHING IN ORDER TO MAINTAIN POWER. THIS OCCURRED AT 30+ MPH IN SLOWING DOWN FOR ACCIDENT/CONSTRUCTION TRAFFIC AS WELL AS EVERY TIME STOPPING FOR LIGHTS OR GAS. ISSUE OCCURRED MANY TIMES DURING TRIP, BUT ONLY WHILE TOWING. AFTER DISCONNECTING TRAILER AND ALLOWING VEHICLE TO COOL/REST FOR AN HOUR ISSUE DID NOT RETURN UNTIL AFTER RUNNING WITH TRAILER BEING TOWED AT HIGHWAY SPEEDS AGAIN.
