I just bought my 07 coupe 3 weeks ago. Noticed that as soon as I hit 50mph the window sound like it was just slightly open or "cracked". Kind of a high pitch whistle noise. Took it to the dealer and they couldn't fix it. They even cut a piece of the rear window molding trying to jerri rig some foam in between the windows. Took it back again, they had it 3 days and now there is no whistle but you can hear it making a weird wind sound. If you look at the window you can see it doesn't really sit as flush as the passenger side. Anyone else have this problem?

 

My '03 has that same thing too. Its annoying, but just turn up the radio

 

That's what I've been doing lol, but it shouldn't be making that sound right off the lot. Not for a 40k car.

 

it should go away after some time, when I had just purchased my 06' g35 a few months ago I noticed it once.. hasnt happened since
