Default Is my BCM going bad?

Or does it need reprogramming? Suddenly, if I open the driver's side door and the trunk at the same time I get the warning chime like if the keys are in the ignition with engine off and you open the door.

Also, if I start the car with the door open, the locks activate open, my Trac Off light comes on and I get Service Vehicle Soon message. If I shut the car off, close the door and restart, it's fine.

Anyone else having these issues?
