Left front drivers door flies open while driving. Door has already been repaired twice by dealers and problem keeps returning.
2011 Lincoln Mkx - problem - intermittent "driver door ajar" warning shown on instrument cluster - cause dome lights to illuminate, and repeated door closing attempts to end "door a jar" warning. Warning happens when stationary and / or in motion, resulting in an unplanned stop. If diving with "door ajar" warning, doors will not stay locked, questioning if doors are really closed.
Two of the doors show an unlocked alarm, even though the doors are fully closed. This prevents the doors from being locked, and the lights to remain on. I cannot set the car's alarm as it will set itself off.
The driver side door ajar sensor is malfunctioning çausing the lights to remain on while driving. This problem has progressively gotten worse to the point the interior lights stay on all the time which is a driving hazard at night. This is a common problem with the Mkx as it is all over the internet. Ford has a bulletin out however will not cover cost of replacement.
Door ajar light stays on. The doors don't lock, dome light stays on, and the alarm goes off multiple times during the night. These things all cause multiple problems. At night with the dome light on it is distracting and lowers visibility. My battery has ran down multiple times.
