I have the same issue (it sounds like it's just behind me on the left). If there is any cross wind, it sounds like my window is partly down (so much so, I usually reach for the window controls and make sure it's up all the way).
I have a service appointment next week, so hopefully they figure it out
I also have a small amount of air coming in the little triangle window on the driver side. I did not notice it until is started getting a little cooler.[/QUOTE
I have this same wind air noise since I took delivery exactly as you describe. Have yet to figure what is causing it and it is worse when cold outside and windy. Drives me crazy.
