When the door is closed, is it flush and well centered?
If you use a soft object [toothbrush rubber pick] can you pry the door and have it move?
Either of those could mean it isn't latching up well, and ride could jar it loose.
It also could be something flaked in the electric circuit, which very few dealerships are at all competent to troubleshoot.
