This is a recurring but intermittent problem the dealership claims is related to the age of the lamps and ballasts and that the entire front end has to be removed to repair it; the fault can be cleared by cycling the headlamp switch from auto to off; internet research suggests it is a known design issue ... what are the facts and what is the best course of action for permanent repair? Thanks.
