Grinding noise on clutch release

Thread Starter
I received the car back last week on 06/11/19. I have put about a 150 miles on it and so far the noise has not occurred again and before it would have occurred after about 7 miles of driving or less. The shifting also feels a lot more precise and tight than it did before. Before it felt a little loose in my grip. They basically ended up replacing almost the entire clutch system. I will upload a picture of the documentation they gave me that lists everything they did later this week.
They also had to replace a spindle as they damaged one getting to the clutch. Evidently you have to remove the rear spindles to work on the clutch. It took an extra 4 days because of the spindle replacement. Sadly one of the things I also took it in for was a "Brakes Worn" message appearing. They replaced a bad sensor (there is a bulletin on this) however it appears another sensor has gone bad so I am taking it back this week. Not sure why GM does not just replace all the brake sensors at once. Another thing my wife noticed when driving to Vettes in the Village this weekend was that the fancy alcantara stitched headliner on the removable Carbon Fiber top was falling off. It looks like the adhesive is giving out so they will fix that as the same time as the brake sensor.
Overall I am glad the clutch issue seems to have been repaired as that was the big issue. These other issues, although annoying, are minor in comparison to the clutch issue.

Obviously the population of M7's is way lower than Autos but they have the same torque tubes. Maybe many system itself is prone to eating pilot bearings otherwise we'd see Autos having this same issue.
Anyhow, hopefully the few folks having the issue will start getting theirs resolved now.

Update 6/18/2019:
Torque tube replacement approved by GM
. Should be here tomorrow. However, no word back from GM on approval of Diff replacement (or lead time).

Glad to hear somebody got this annoying issue fixed. Now to convince my dealer to fix it and decide that I want to be without it for a couple weeks. Thanks for posting the updates. Best of luck.

Still waiting on word on the ETA for a replacement differential (not related to failing clutch pilot bearing). The issue has been elevated by the dealer and they have a ****/SWAT case on the differential. Hope it gets here soon I'm going into withdrawals.
The Z06 is going to be a dream after driving the V6 base model Camaro for a month or so.

Maybe a defective torque tube for sure, but I wouldn't think the tube takes any more abuse on my car than many others (unless folks don't know show to shift smooth). It is driven hard every now and then (for maybe one or two shifts) but other than that it gets babied. I drive with rev match on 99% of the time.

Woohoo. My baby is back for the grinding/"grrrr" noise issue in clutch area. I'll give my post fix impressions this weekend.
Just like forum user "daus", the pilot bearing "went out" and wiped out the input shaft to the torque tube causing it to be replaced as well.
She's a beast after driving my 4-banger Camaro loaner. That being said, the little motor does pack a punch with its little tiny turbo.
UPDATE: Drove the car today for 50+ miles. Feeling good so far. Here is the dealer paperwork for those interested. FYI, I'm not sure what was going on with the differential, they said they heard something but I never heard it. Glad this $10K was on their dime. ; )

I have a 2018 Carbon 65 Z06 with the Z07 package that has about 10k miles. I have been getting a grinding noise that seems to come from the shifter area when I release the clutch in first gear. It did not occur very much at first but lately it is occurring every time I drive the car. The car has been in the dealership for 3 weeks now. Here is a link to a video I recorded with the PDR that I have given to the dealership:
https://www.youtube.com/watch?v=1xdxCuuU51c
The dealership and GM do not seem to have a clue to what is going on. I guess GM even tried to tell the dealership it was normal. I have owned four C7 Corvettes with three of them being manuals and never had this issue with nearly 40k miles driven between them. Anyone had this problem or maybe know what it is? Starting to get very frustrated with it and any help would be appreciated. Also here is a link showing the Carbon 65 if you are interested. I love the car however this issue really takes away from the enjoyment. Thank you in advance!

All. I brought my car into local Chevy dealer 3 weeks ago and they began diagnosing my car two days ago! Needless to say I aM more then frustrated. I just went to the dealer and they said they think the clutch actuator cylinder needs to be replaced and possibly the clutch itself but that is still TBD. And if it’s the clutch they are claiming it is NOT covered under my factory warranty. Is this true??? I don’t see how a car under factory warranty cannot be covered for something like this. Can anyone please chime in and help? I believe Rand got his repaired and it was covered. Thanks.

My Carbon 65 Z06 is still in the shop over this issue. It has been over a month and no progress even after sending them the video and video of other cars having the problem. Can't believe it takes them over a month to fix this. Very disappointed in GM tech support at the moment. You would think that for a Carbon 65 and a guy that has purchased 4 brand new Corvettes they would give it a little priority.

Yes, the clutch is considered a "wear item" along the lines of brake pads, not a warranty item. I talked to my dealer about the noise and get about the same story, "it's probably the clutch, you'll have to pay if it is", with them saying that, even if it turns out to be something else, I'm sure they'll charge me for the clutch. Mine's been making the noise for over a year, but it's intermittent and of course never happens when I take it in for service. I'm fairly certain it's pilot bearings, but it's not a trivial fix and they'll do everything they can to discourage having to take it apart to look at it.

They basically replaced my entire clutch under warranty and I no longer have the problem. The shifting is even tighter now which I like. That is BS if they say it is not under warranty unless of course your warranty has expired.
