Me too. 05/08 built no premium sound. Bought as new last week, and heard it twice. First one was really loud bang! So my reaction was to look into left side mirror to see if I ran over something. But couldn't see anything on the ground. Second one was moderate.

I will be taking my car for 1st maintenance in a couple of weeks, I think...so I'll post any updates later.
