Hello, I am on this site searching for info on wind noise as well. This is my second Subaru Outback Wagon and both have had wind noise problems. My current problem seems to be because of the mirror gusset seal. I had my old car "fixed" at the dealer but it never really went away. On my old car, it was on the driver side, this time it is the passenger so my sense is that it is a faulty gusset/seal design. If you find a fix, please let me know. I taped the outer seal of the gusset with electrical tape to see if it made a difference and it does seem to, but hasn't completely fixed it or I would consider filling in the crack with silicone.
