I've had my truck in for the 'newest' GM fix which was this new 'gasket' that was suppose to work. My service dept. even put 2 'gaskets' in the space. At the time - no vibration! But it's been a few months and the vibration has slowly returned. It's been so loud sometimes that even the radio can't disguise the noise.

I recently emialed my service dept. and here's what they suggested:

The only thing that I could possibly do at this time would be to apply a urethane adhesive between the light bar and roof of the vehicle. This has been taking care of the issue for some other customers. As far as the side moldings on the windshield, they have not distributed the the new parts yet.

I am so not interested in 'glue' as the fix to this problem! Can't GM fix this?! Seems we all have enough experience they should be asking our advice.

The DS A-pillar plastic is the black plastic trim that goes up the side of the windshield on the drivers side. I don't know if I was just lucky in the fact that it fixed the issue on mine but maybe when the new ones get to the dealership it will fix yours. I have also had mine get so loud that you could not understand what was on the stereo. For a week or so before I took it in this last time the vibrating noise would start at as low a speed as 50 MPH. So far after close to a month I am still having no issues. One thing you might try as a test to see if it is the marker lights or if it is the a-pillar is put some electrical tape along the leading edge of the marker lights. This should stop air from getting under them and causing a vibration. I believe someone did this and it worked for them. Let us know what happens if you do try it.
