Headlight would malfunction. First only high beam, then low beam as well. Rings would be on but headlights themselves would go out. Took to stealership of Lauderdale BMW. They replaced the module and i paid for it. Next day, same issue; I brought it back and they said well its a non refundable part and i need a whole new headlight. When asking why, they said its not covered by 50k warranty due to neglect. No accidents occured, and no damage to headlight. 4700 later, i have a new headlight.
