sunroof opens and windows go down when ignition turned off

This is the same behavior that occurs when the unlock button on the key is held. Is it possible that the unlock button is being held down on your primary or spare key?

I only have a primary key, no spare. The unlock button appears to be functioning properly. Lock/unlock buttons work normally. If close the windows and sunroof, start the car all is good. When I push start/stop to stop the engine, all is good however, when I remove key from ignition sunroof opens and all windows go down following a short delay, same as holding down the unlock button.

It could be an issue with an electrical short, or the door actuator. It points to the actuator believing it is receiving the unlock command erroneously. I would start there. You should be able to pull a fuse for the central locking system to prevent it from reoccurring until it is resolved. If you do that, you would just need to lock and unlock with the key physically in the door. Hope this helps!

Thank You. Will investigate.I did try to lock doors with manual key but doors did not lock. Can lock/unlock with fob only.
