Im buying a new car and the dealer says adding an aftermarket sunroof will void the warranty. Is that true?
It is not legal for any dealer to void a vehicle warranty because an aftermarket product has been installed. The only exception to this is if the dealer can prove that the aftermarket product was the cause of a warranty failure. It is also not legal for the dealer to void the warranty if an aftermarket product is chosen over it’s factory equivalent. As an example, a dealer may not legally decline a warranty claim for a faulty transmission because an aftermarket bedliner or rear wing was installed on the vehicle. Further, the dealer can not claim that the use of the factory equivalent is mandatory. Aftermarket products give consumers freedom of choice. With most aftermarket products, you do not sacrifice quality to get that choice. There is no substitute for good consumer research, but dealers can not restrain consumer choice based on this argument.
