It used to be, not terribly long ago, that when one had simple or even complex issues with their American-made vehicles, all she would have to do was go to her local auto parts store and buy the replacement part and swap it out. But now, a bad brake light bulb isn’t fixable with just a new brake light bulb. Apparently, even something so simple as this or switching out a dead battery for a new one requires a trip to the dealership….as suggested by the car owner’s manual.
Well played, GM. Well played.
