On my '05 Highline the door control unit failed ( only one side though) , so the winch doesn't work and the car thinks the door is still open even when you have closed it manually. You will have a door-open indicator on the computer display even when it's shut.
If your dashboard display indicates that the doors are closed, you may luckily just have a fuse problem.
If the dashboard display shows the door to be open, the door-open alarm will be going off if you try to drive- stop, and press the side door lock button on the dashboard- it should cancel the alarm.
