Wish I had found this forum sooner, I got the roof rails and there is noise 15-40 mph, the closer they are the more noticeable. The dealer was baffled where the noise was from until I showed him this.
I just got mine a week ago with out the roof rails, then had them installed and have the same issue. The dealer couldn't figure out my wind noise, thanks for your post. I just removed the rails and the noise goes away.
