: Sunroof noise at 100+mph

At about 100mph the sun roof on my CTS-V starts to lift and make noise. Anyone solved this problem?

I described this in a threas about 2 months ago, on this forum. As far as I know there is no solution.

Funny you should mention this. I had not noticed it before, but the other day when I was making a C5 get smaller in my mirror I heard it somewhere between 100 and 125. Kind of wanted to look up, but was a little busy at the time. Then it stopped. Ran to about 140 and did not hear it up there.

Funny, I found out that if the sunroof is open while at +120mph don't bother trying to close it unless you slow down first. I did just that last week. Around 120ish it got really loud with the roof open so I switched the knob to close it but it didn't budge until after I had slowed to around 95 or so.

My first V's sunroof wasn't closing correctly and it made a lot of noise at high speed. The V I have now doesn't have a sunroof noise problem at high speeds.

When you bring the car in for an oil change or recall ( or just for this problem ) the dealer should be able to adjust it quickly.
