You have "comfort access" from the sound of things. Or whatever it's called.
Most cars I've worked on(and I dont know why this would be any different!) can be adjusted for the hinge, and latch for each door. If you haven't done this before I would get a dealer or independent shop to take a look. Failing this get them to take a look at the sensor.
Does the warming go away if you hold the door closed?
