GXP wind turbulence
I have noticed something strange with my '05 GXP. If I have the sunroof open more than 3/4 of the way, there is a wind turbulence/buffeting resonance that really gets annoying between 35-38 mph. Even if I roll down both front windows, it makes no difference.
I also noticed that my Bonneville does NOT have a pop-up wind deflector when the sunroof opens like my '01 Alero did. Is it supposed to be there or did someone on the assembly line forget to install it? Does anyone else notice this problem? Thanks!
