I beg to differ, I think the carbon fiber roof is much more rigid with less movement than the translucent

You may very well be correct. I dont have a different top to try in the same car for a comparison. Could also just be a difference in that particular roof but not with all roofs of that type.

It's hard to understand unless you have both roofs, the translucent seems flimsy however it is very nice to have it on the car for that open feeling

Mine is new and started this in the first week. It's intermittent so far, but I will be working on the issue soon.

In my case it was a cricking sound, which was coming from the front driver side of the roof panel. It was resolved completely when I pulled the conical grommet out from the peg and reinstalled it with an additional rubber washer spacer at the base to keep it from getting pushed all the way down again.
When the conical grommet gets pushed down too far to the base it no longer provides the buffer and locating properties needed to keep the peg from contacting the roof, which caused the cricking noises. It needs the conical shape at the end to help keep it centered in the hole so it should be used instead of replacing it entirely with a flat washer.
It was pretty tight and didn't slide around on the peg very easily, so I could probably have just pulled it up from the base without adding any extra washers, but I figured that would help keep it from getting mashed down again.

I've had my C7 Coupe for 1 month and there are no creaks or rattling coming from the roof. That being said.....I haven't taken it off yet.

This trick worked for me as well.

I cut the fingers out of a disposable rubber glove and placed them over all 4 strikers. Hope to find this is the source of the noise and then try the rubber washer trick. I am guessing an o-ring will work as a rubber washer.

My problem is (tentatively) SOLVED!!!!

Problem: Drivers side front roof panel creaking/popping near/at post/striker location.

Resolution:
Took roof panel off when giving my baby a bath this weekend and inspected both the panel and car striker/post area.
Discovered post on the panel had some partial pieces of industrial shipping/duct tape on it.
Noticed that the post/striker hole on the mount location in the car had a small switch/indicator sticking out. (my guess is that it indicates if roof panel is installed).
Also guessed that the switch/indicator on car was rubbing against post with tape causing a rough pop/creak noise.
Removed tape from the panel stricker/post and applied some grease.
Installed roof panel making sure the seals around the entire panel were properly seated and not mushed anywhere.

Result: 100% completely quite ride this morning, not a single creak/pop. I went over 3 sets of railroad tracks and some rough roads too.

Right now I am happy but tentative to say its fixed for good. I'll report back later on if it stays quiet.

I'd recommend putting some grease/lubricant on your drivers side roof panel post if you are getting creaks from that location. The grease will help keep the switch on the car from rubbing and popping against the roof panel post.

My roof is quiet as a mouse. My dash, on the other hand, creaks like a pirate ship. Worse with he roof off.

I had a few creaks when I drove, so tried the silicon grease to the seals trick this weekend......now it creaks 3 times as much.

Guess I need to try a few more tricks. 1) have to look closed, but don't remember any grommets on the front posts 2) when closing the rear latch, seems to be a 1/4 inch gap and puts just a little pressure on the hook when latching.....may need a turn.

Just wish I hadn't lubed it......or maybe I put to light a coat on.

Mine started rattling like crazy last week. I think it loosened up because of the extreme heat here in Texas.

Today when detailing the car I took the roof off and tightened the rear latch.
It tightened a full 2 turns without any effort, that thing was way too loose!

Needless to say my car is now silent, no more creaking roof!

I have had this problem with my 2005, 2007, and my 2012.

Z51 cars tend to be creaky because of the stiffer suspension. Its why I no longer buy them. Haven't had a creaky car since.
