Same here... Sometimes when I went over a bump or I did a sudden stop, my audio went back to normal... According to the Service Manager, it IS the faulty audio unit. If you are still within warranty I suggest you take yours in right away... Not sure whether there is a TSB for that.

 

i just saw the new sedan for the first time this mornign and it looked just as expected nohting crazy i must say but i didnt drive it
