I get into my beautiful 1999 Ford Explorer Sport and notice during the night the clock on the radio must have stopped...though it is currently working the time is off by several hours. This has happened several times over the past few months. The car starts without issue. Now I need to take my car in for oil change etc on Friday morning. If I mention this to the car guy, will he try to rape my wallet for a repair that is not vital to the car? What could it be and should I be worried about electrical or battery issues? This is the problem I need help with my brothers.
