This is a minor issue for sure, but I don't understand why this happens.
Sometimes when I get out of the car, all the time-delayed lights will go out at after about 30 sec's, but the USB port light will stay on for up to an hour. Other times, they will go out shortly after the other lights go out.
Why would that be?
Obviously I looked in the manual. There is precious little information about the USB ports and nothing as to why they may stay lit or not.
Has anyone else noticed this behaviour, and/or have an explanation for it?
