My current problem, after two weeks of ownership, is the sound system has failed. No sound from FM, Satellite or media player. It quit a couple of times last week but came back to life after a few minutes. Totally out this time. What's unusual about this failure is that the volume control and Sound menu settings sometimes give an error message, other times it looks like they are functioning normally even though there is not sound coming from the speakers. I've poked around all the MMI settings and can't find anything that helps. Back to the dealer next week.
