I've seen stuff like the below posted for the new Camaro which is very reassuring but, the way it's worded for the Z06 seems like it would be far more difficult to win the battle if they show the car has been tracked.
“If you’re not modifying your car and you take your production car to a track day and you have an issue with one of your parts, it’s covered under warranty,” [Camaro chief engineer Al] Oppenheiser told Motor Authority. “That’s pride of craftsmanship that we know it will stand up to track use.”

Which is the same thing I pointed out in Post #2.

Which was edited and added after the fact to post #2.

Looks like they are trying to pull a Nissan GTR on you. "Yes, the car has launch control but we will void your warranty if you use it". Lawyer up

Sounds like this is a good problem to send a letter to Mary Barra about. First, the dealer's tracking response is suspicious and the fact they will not let you talk to the GM rep is suspicious. When you have a dealership like that you need to start at the top and Mary sits right at the top. Every time I have sent letters to the President or CEO of GM I have received excellent results. Just politely tell them the problem, what will make you happy (don't make it a guessing game) and you should receive some sort of acknowledgement from somebody assigned to review the case within a short time after the letter has been received. Include copies of all repair invoices and amounts you have paid. The first time I did this the dealer was found to be charging me for the repair and then turning around and charging GM for the repair under warranty. That complaint had a few people at GM upset.

...and go after the guy that sold the OP the car. Not GM.

Good luck with that one. It was likely sold in an "As Is" state, meaning there's probably nothing our OP can do but take it on the chin and pay for it himself.

just got back from inspecting the diff at the dealer. It clearly hasnt overheated or burned up. Just improper wear and tear on the rack and pinion probably from improper factory set up. most likely the same noise i read about in lengthy posts here on the forum where the only fix is a new diff. This has zero to do with the track and the corvette tech almost admitted it. The service manager said hes tired of seeing gm deny so many claims so hes not willing to risk it..Great warranty...def. not going to drop 130 k on a zr1 with a company that wont cover the warranty when somethings not right. The manager is going to try to get the local rep to reconsider but im not holding my breath. It just makes me mad that they basically made up there minds that they wouldnt cover it befoe even breaking down the diff.

Did I miss where it stated whether the rear was, or was not, properly broke in, or is JVP just being a douche for no reason?

So lesson learn when a dealer asks you were you racing or on the track when it happen the answer is no. Let them prove otherwise....

I'll still bet the fluid level was low from the factory.

Amazing that you can tell from all the way across the Internet that the car was abused.

My 2015 Z06 was broken in perfectly per the manual and my diff still went at about 750 miles. And of course GM covered it.

It's not that I reject your theory that improper breakin can cause a failure, because that part is true. The part where you attribute every diff failure to owner negligence? That's must nonsense.

Unless I missed it, there's no indication that the track use was during the breakin period.

I never said there was. Read my statement carefully. And with that, please also reference Occam's razor.

That Service Manager is blowing smoke. GM honors their warranty even for track related failures. There are a lot of incidents of people having failures over the years and GM covering the failure. From the way the guy sounds the dealership is being watched closely by GM for fraud. Were you actually talking to the Service Manager or the flunky that meets you when you drive in the shop and writes up your repair concern?

How do you know whether or not he ever talks to the GM rep? If this isn't covered you need to insist on talking to the GM rep when he comes by. That may mean leaving work to go see him when he/she is at the dealership.

Talk to somebody in GM and the best person is at the top. You will get a response.

Maybe if he's tired of DOING HIS JOB, he should find another one. Also, exactly what is he "risking"?

Again, it's his JOB to submit repairs for warranty for YOUR car. YOU are the vehicle owner, the warranty is a contract between you (as a successor to the original owner). Manufacturer's warrant the vehicle and the warranty transfers with the car. Aftermarket or third part warranties are often a different story, but not the GM warranty.

Tell him to shut up and do his job. Or, find another SM who actually understands what his role is in the process.

GM published a list of cars which are covered on track, Z06 included. I don’t have it handy, but I’m sure you can find it if you google it.

It’s one of the key things that separated the Z06 from the GT3. The porsche owners manual specifically states track use voids the warranty.

I’m planning to buy a ZR1, but ONLY if track use is covered.

If the OP isn’t taken care of, I’ll have to reconsider the ZR1.

The C7 e-difs are known to be under filled with fluid from the contractor Linimar. Checking the dif fluid level is not part of the PDI, even at Museum delivery. One CA customer took Museum delivery and oly made it to TX before the under filled dif failed.

Talk to you service adviser about this, likely no satisfaction, the go thru GM channels.

I think Bill has given the best advice. If you don’t get help from the Service Manager a well written letter to Mary Barra should help.

Exactly my thoughts. Typical fanboi attitude of him. Unless the diff is cracked I see no reason to jump to that conclusion.

Hope you get this resolved. I noticed that a couple of times you referred to the rearend problem as a rack and pinion issue. That is the steering rack in the front of the car. You probably mean to say ring and pinion which is the gearset in the rearend.
