This may be related but I had an issue with my car (non comfort access) where the headlights would come on automatically or the Taillights would not shut off. I have also had it where I would shut the car off, take the key fob out of the ignition and the car would act like it was still in the ignition without the car running, nav, radio and AC/Heater fans. The dealer just said it was a software glitch, updated the progman and It has not happened since.
