I have been an enthusiastic corvette owner for past 30 plus years having owned 7 and the C7 - 15 is by far and away the best, but the problems with the roof latch causing significant rattles is terrible and although I have had the local dealer change the assembly per the GM service notice it still continues as a problem. I actually brought it back to the dealer last week and the rattle got worse. The dealer gave up on the repair saying they didn't know how to correct it and they prepared a field serve report to GM.

For such a technologically significant car it's amazing the engineers at GM can fix a rattle. I filed a report with Chevy directly and remains to be seen what they do about.

Very frustrated

I have not developed that problem yet ....may I suggest that you request/demand a new roof .... or perhaps the dealer will give another roof a try ...if they have the inventory ....

Removable joints are hard to manufacture to tolerance. Most if not all squeaks and rattles are not related to design but rather tolerance stack ups and manufacturing difficulties.

As an engineer I can design a great part but if it can't be built or can only be built poorly (due to the inherent nature of the design) then there isn't much I can do.

The only way to remove roof rattles is to have a fixed roof.

I had my local dealer replace the removable roof pins in the front and the latch device in the rear on my 2015 C7. I also had a few rattles before the repair.

After I had the roof top repaired by the local dealer, I still had rattles and have determined that the problem was my garage door opener that was clipped to the sun visor. Once removed from the sun visor the rattles stopped. Apparently the insides of the garage door opener and outside clip were loose.

What a difference. I opened up the garage door opener and secured the small IC board with Gorilla Glue and glued down the clip on the outside.

It made a major difference, no rattles. Can't say you have the same problem, but if you have a garage door opener clipped to a sun visor, remove it and see what happens .

Have you looked at tightening the rear latch hook yourself?? There are several posts on that "repair" on the forum - some with pictures - and it worked for me! And it is easy to do!
Here are 2 of the posts!

After owning a C4,5 (several) & 7, I can say that I would love to see a fixed roof Coupe and end the roof rattle problems. GM - PLEASE NOTE!

I never remove my roof! Owned my C7 over a year now and its never been off, but it rattles.

I miss T-tops.

With all due respect for your engineering background and explanation as an avid consumer of the corvette I believe GM has a responsibility to produce this part so it doesn't malfunction. This, to your point is a chronic problem, but you would think after after so many years of producing the (C4-7) GM couldn't figure this out. Obviously, they recognize the problem, based upon the service bulletin, and still they have come up short in resolving the issue. I think they shoukd offer to replace the roof in good faith.

My 2014 roof has been off about 5 or 6 times. So far no rattles after 19,000 miles. Maybe I got lucky with mine.

'15 here and only a rattle or two when driving on a very rough surface, Normal roads are no problem, had the roof off and still no problem. Another lucky one here.

The more parts the greater the stacking problem. Are a lot of parts involved in the latch assembly? Solution is tighter tolerances of all or certain critical parts. Could be caused by tolerances that are too wide OR failure to control present tolerances. That would be called sloppy manufacturing and incompetent QA if that were the case. It would be interesting to have a sample of the parts involved plus the manufacturers prints with tolerances. Just measure the parts and know the answer. I suspect the manufacturer knows the answer. Then again it could just be a poor design that no amount of tightening or control of tolerances would overcome.

Just my opinion and I'm an engineer as well.

If I had to guess, I'd say the biggest issue is frame to roof tolerance and flex. Obviously since the roof and frame are first introduced to each other in final assembly I'd say that creates the biggest issue for fitment issues. The strikers and latches I think have to be very precise and inherently the design is not.

Much can be done by liberally applying grease on the weather striping and to the striking and latch hardware. This is the "typical" solution to noise, however people who have noise due to roof to frame flex are SOL (this latter one I would hope is quite rare), as opposed to tolerance fit (which I feel is common).

On my C6, my roof was typically quiet and I was notorious for greasing my weather stripping. But in the end I don't think you will ever get the noise free operation of a fixed roof which is a part of the frame structure.

Maybe someone can develope a "latch" that allows the top to be bolted in place. That should solve the problem for owners who don't remove the top and prefer a fixed top. Isn't that how early targa tops were attached?

Count me in on the lucky ones

I took mine off once and that started the rattling. I had the TSB performed and the rattle went away. I also haven't removed the roof again.

Based upon the posts, it sounds like latch assembly rattles is just a bi product of a non fixed roof. I wonder if this a common problem of other cars with a removable roof??

Its hit or miss. I have had a few C4s, C5s, and C6s. Some have rattled more than others. But, they all rattle at some time or another. :yes nod: And, when i get my C7 I expect some rattling.

wgood

Mine (2014 Z-51) squeaks above the passenger side back position and before the 15's came out I suggested when didn't they come up with a 2 latch system instead one 1 like the c5 -c6 !!! Wayne

I have a '16, and have taken the roof off several times, and have no rattles or squeaks on smooth surfaces. I occasionally hear barely discernible noise on rough surfaces, which would be consistent with most vehicles regardless of a detachable roof.

I don't necessarily agree that a new roof will solve the problem as they are mass produced separately and not inherent to car. If the hardware is new, and the latches have been adjusted, then the problem would seem to stem from the car itself, and not the roof... possibly the seals are not properly bridging to two components.

A new roof under warranty would be able to rule that out as a process of elimination, but may be difficult. Instead of a new roof, wonder if the dealership would temporarily install a roof from another new Vette? If it solves the problem, then that might help your warranty claim. If it doesn't, then they can focus their attention somewhere else...

Problem was very bad on my C6 until I noticed that the pins on the front of the roof panel were loose. I torqued them down and it has been quiet ever since.
