If you you hear wind noise around the A-Pillars, then you may have what I had. There is a SIB (service bulletin) for this issue, it's SIB 51 04 13.
I just had this repair done and it made a world of difference for me.

They replaced the windshield drip moldings (left and right) and used the new blue clips to secure them. The whooshing/buffeting noise is gone.
The drip molding is also a slightly different design in that there is an added reinforcing flange at the bottom. It's definitely an upgraded part from the original that I had on my car which didn't have these flanges.
