My door ajar light just comes on at random times and every time it is the trunk. It will come on and I'll go back there and pop and close the trunk then it will come on again later while I'm driving and I hadn't even messed w/ the trunk since I fixed it. It's just done it about 2 or 3 times. I don't know what it is w/ the trunk, but every time the door ajar light comes on it is the trunk. I rarely use the trunk, so it's not that I’m not closing it good. Anyone else have this problem?

 

Could be a short or the trunk is closed but not sealed all the way. I would take it to the dealer and make them fool with it

 

Faulty sensor?? Have the dealer check it out.
