Just thought I would let everyone know that if they are having wind noise in their XF's take them into your service department. There is a service advisory on them and they will replace the weather stripping for free. My dealership told me this is common complaint and that Chrysler has let them know to replace them. I had mine done a week ago and my car is so much quieter than it was before. I use to have a good amount of wind noise in both windows but it has subsided.
