Just thought that I would make everyone aware of a problem that I am having with my GXP. After they fixed my HUD, they noticed that the drivers side front window didnt sit properly in its track. Apparently, the window is too far forward, and that is the cause of most of my wind noise. They then went to the cars that they have sitting on the lot, and noticed this same problem in those as well. They have ordered me the window track so that this can be fixed. Im not sure if the dealership that I am working with is just getting poor quality GXP'*, or if it is a problem with all of them. :? I just thought that if you owned one, you would want to make sure yours is right.

how many did they find out was wrong???

Not sure how many they have on the lot right now, but a week or so ago there were 5. So far, as much as I hate to say it, I wish I hadnt bought this car....

My windshield was the same as well. The windshield was never positioned properly. GM is going to replace the seal.

my car has an unsatisfactory amount of wind noise as well...though I think mine resides more with the sunroof... I have to close the sunshade to help lower the noise.
