A couple of my neighbors have witnessed our unattended 2010 FFH's exterior lights come on and the about a minute later, go off. No explaination. They noticed this at night. The other day, my wife noticed the same thing happening as she approached our car in a parking lot during the day. She was about 10 ft from the car and no key was involved. On for a bout a minute, then off. Has anyone experienced this problem or have ideas as to the cause? Thanks for your help.
