I'd like to see a poll for anyone who had the problem fixed!
I've only seen one post with someone saying the problem was made better and even at that.. it was not totally fixed.
I've posted this before and there is different degrees of the wind noise problem.
When there is what I know, and experienced, a real bad wind noise problem, it is not just outside wind against the vehicle.
Air is getting into the vehicle and a vehicle with the problem is unmistakeable! ... and usually has a lot of "whistling" noise.
If the vehicle has wind noise,.. it is regardless of how windy it is out.
It's one thing to hear the wind outside .. on a windy day,.. and another to hear it whistling into the vehicle.. with or without a windy day.
Also, it's not as bad in warm/hot weather and really bad in cold weather.
I've tried everything short of sealing the whole vehicle with silicone

and nothing changes.
Since Winter started my wind noise is a Lot worse than it was in the Summer.
I now have a lot of whistling in the top of the door and roof area and it's louder when I open the Sunroof "shade" cover.
I recently taped up the Sunroof solid and nothing changed.. same whistling noise.
I've driven a few other vehciles off the dealer lot and they have the wind noise.. some worse, some not.
I don't think GM knows what or why the wind noise is there.
It's not in all the vehicles to be sure, but it's also totally random and in more vehicles than acceptable percentage wise.
I had access to an 08 for a whole week and it was totally quiet under all weather and driving conditions.
Go figure
