Thanks for the reply. I tried it last night in an empty parking lot that was pitch dark and the lights did not turn on when the door was opened (only the ambient lights went on). I have also tried this in daylight with the lights turning on so I don't think it's a sensor issue. Also, I have tried this with the auto headlights on (control knob turned to the full clockwise position) and with the headlights completely off (control knob turned to the full counter-clockwise position)
I agree that it might be time to visit the dealer with the FoFo :-). My fear is that this is intermittent, which is the "kiss of death" when bringing a car to a dealer for repair. What I mean by this is that unless the problem can be duplicated in front of a service representative, it is highly unlikely that they will find anything wrong and simply state "working properly".
