2020 ford expedition. I had the vehicle at the dealer for transmission service. When i got the vehicle back, the headlights stay on for about 2 or 3 or 4 minutes after vehicle has been turned off and locked. it has always been set for auto on headlights. why is this. original owner. it happened after i had transmission service at the dealer. any ideas? I cant find anything in settings. When i used to get out of the vehicle and lock it, the headlights turned off after 10 seconds or so. Thanks!
