F150 spontaneous alarm activation
Started at about 22,000 miles
Always at night, also noticed an
occas inside dome light comes on
or dash says "door ajar"
It should be warranty still, the alarm goes off when the truck sees that a door is "ajar" without being unlocked and thinks that someone is breaking into it. One of the latches isn't functioning properly.
Check rubber door seal, it might've came out of the rail or any other obstructions causing your door not to close alltheway and eventually pops out, acting like someone opened it.
