The other day when I locked the car after parking it I noticed that the fan was running for what appeared to be an extra long time. I got back in restarted the car and then after a minute or so turned it off. What I noticed was that the Nav screen which was previously on did not shut down when the engine was shut off. I waited a while and finally heard the fan shut down, however from outside the car in bright sunshine I couldn't tell if the Nav screen was off. Upon returning to the car everything seemed ok , so I went home and parked the car in the garage. When I went to lock it down there was NO RESPONSE, the car completely shut itself off. I tried the other key, but no success, obviously they flat bed my #25 series back to the dealership. Anyone else have similar issues, I will persevere with these annoyances because there isn't another car out there to compare to the style and statement this car makes.
