No real event leads to this failure. Problem is the "door ajar" light on the dash. It detects whether a door is partially open. The switch in one of the doors fails for no reason. When it senses this falsely, the dash warning light comes on & beeps a tone & quite often the interior dome lights turn on. The dealer says to lubricate the door latches & work them several times. I've done that many times & it does not help. When the switch fails & the light comes on, it may be brief but other times, I'll park the truck & walk away & the light remains on for quite a long time. I'm sure I'll come out to a dead battery one day. Please check this out. I have seen hundreds of other reports like this on the internet - for various Ford model cars & trucks. The light coming on is very distracting and could be dangerous.
