Airbag light came on. Diagnosed as faulty wiring. Dealer got it to go out, but if it comes back on again they say the entire passenger side airbag needs to be replaced. Dealer cannot say if the air bag will deploy in an accident and says that the manufacturer will not say either. Now, the light is out behind the heater control button. Once again diagnosed as faulty wiring. Faulty wiring sounds like a factory problem to me. All services on this vehicle have been done since day one as recommended by the manufacturer.
Contact states: while driving radio was going on and off along with automatic locks. Took vehicle to dealer and replaced radio but found no problem with locks. While on interstate or for long periods of time the locks begin flipping on and off. Had to replace two interior light bulbs as well. Dealer does not listen to complaints.
