My 2015 Z51 Coupe emits a "popping and cracking" sound from overhead when the roof is installed. When I remove it the noise goes away. I note that earlier C6 owners had this problem and GM issued a fix bulletin and replaced the roof if the fix didn't work. Anyone else experience this? I have not had it into a dealer yet but I was told that there wasn't any any bulletins on this problem at present.
Update: So, I took it to the dealer and they resolved my problem. They called GM Tech. Support and they instructed them to place a thin shim(s) such that the locking mechanisms placed less stress on the roof when secure. They did this and test drove the car with no further noise. I drove it home from the dealer and all seems well!
Further Update: Upon spending more time with the car the problem wasn't fixed. When the sun beats on the top it pops and cracks when driven. Dealer says GM is aware of problem and will be issuing a bulletin early July. They also state that replacing top won't solve problem but I'm in disagreement with this. They further note that I'm not the only one experiencing this. But you wouldn't know it from the responses to this post.
Update: Still making the noise and still awaiting GM's bulletin.
GM has released the Service Bulletin as of today - 10/01/15! My Service Manager received a call from GM this morning informing him that they have released the fix for this roof noise problem. "Here is the bulletin # 15-NA-016 the doc id # is 4277613 for the roof issue on your vette any dealer will be able to pull the repair procedure up thru SI in global connect." Let's hope this fixes it!
