NHTSA Complaint #10940438 — 2015 FORD F-150

IN COLD WEATHER, THE REAR DRIVER SIDE DOOR LATCHES ARE INOPERABLE. THE DOOR LATCH FAILS TO ENGAGE, ALLOWING THE DOOR TO OPEN WHILE THE VEHICLE IS IN MOTION. DURING RIGHT HAND TURNS, BUMPS IN THE ROAD, OR WHEN LIGHT PRESSURE IS APPLIED TO THE DRIVER SIDE DOORS, THE VEHICLE RETURNS A "DOOR AJAR" WARNING AS THE DOOR OPEN ITSELF. THIS IS ESPECIALLY DANGEROUS IN THE "SUPERCAB" CONFIGURATION, AS THE REAR DOOR ALSO CONTAINS THE SEAT BELT FOR THE DRIVER. IF THE DOOR WERE TO OPEN FULLY, THIS COULD DISRUPT THE DRIVER'S ABILITY TO CONTROL THE VEHICLE, OR POTENTIALLY THROW THEM OUT OF THE VEHICLE. THIS SYSTEM FAILURE CAN ALSO BE EASILY REPLICATED WHEN STATIONARY. OPEN THE DRIVER'S DOOR AND LIGHTLY PULL ON THE REAR DOOR. YOU CAN SEE THE LATCH FAILING TO ENGAGE AS THE DOOR MOVE FREELY AT THE BOTTOM INSTEAD OF STAYING LOCKED SHUT. WHEN IN MOTION, THIS PROBLEM OCCURS AT ALL SPEEDS, FROM PARKING LOT MANEUVERS TO HIGHWAY TRAVEL. THE FIRST INSTANCE OF THIS FAILURE OCCURRED AT APPROXIMATELY 17*F. THE DOOR JAMBS AND LATCH ASSEMBLIES WERE CONFIRMED TO BE FREE OF ICE, SNOW, OR ANY OTHER DEBRIS.
