Radio speakers started cutting out and making popping/crackling noises for weeks, even if the car was turned off or if the volume was turned down, then the radio died completely. I have seen many other complaints from other people with the same problem. Dealership said I would have to replace the entire radio for $400, but apparently this is a common occurrence in these cars.
