Default How to know?

Im in the market for a '15/16 Z06 Auto.
I guess the only way to know if it suffers from the overheating issue is if it has been taken in for warranty service and it has been recorded on the service history, correct?
Is the GM service history the only way I can check? Is there a private company like carfax that will give me service details? Thanks
Will

I think the only ones that have the overheating issue are the ones driven on the track for at least 15 minutes. If you're just using it as a street cruiser where you are going to punch it once in a while, I doubt you are going to have any problems, unless you want to risk jail time.

I'll probably be tracking it every so often. I also worry about it being on the service history. I would never buy one knowing it had the issue.

Why?
New vehicles come w/ a warranty covering defect(s) and it's a rare for any new car that's flawless.

A8s tracked seem prone to running hot or even overheating, it's a known issue & means either driving it w/ appropriate rest periods so it can cool down or beef-up cooling to compensate, assuming A8 systems can be modified w/ some factory add-on or aftermarket product.

I would never buy one knowing it had the issue.
Why?
If a GMVIS showed car was repaired under warranty and there were no other claims for same issue? I'd consider it a solid car w/ a known bug satisfactorily corrected w/ documented proof.

Now if I were in the market for any MY A8 equipped C7?
It'd be the A8's history, via GMVIS, I'd be looking closely at.

Again, more than one dealer visit for same problem is to me a glaring red flag, but not a one time event.

GM and the Corvette team recommends to drive it in manual only on the track. Paddleshift only. It's not supposed to overheat in manual mode.

Do they have a known fix for the overheating issue? Why would there still be lawsuits if it was being fixed?

Sorry if this bothers you. Perhaps you could've just ignored the post? I asked a specific question if the service history is only available from GM. Thought someone could save me from reading through 8000 posts.
I began to read the thread the other day and I didn't see the answer. Nor did I see if there is a solution to the problem.

As for whether there's a different source of info, the answer is there is no other reliable source. Services like Carfax are completely voluntary, so a dealer or shop doesn't have to report anything to them. Assuming a clean Carfax report means nothing has ever been done is erroneous thinking.

I do know that at Spring Mountain all the A8’s were driven in manual mode and never saw any overheating.

I said, excerpted: "A8s tracked seem prone to running hot or even overheating, it's a known issue & means either driving it w/ appropriate rest periods so it can cool down or beef-up cooling to compensate, assuming A8 systems can be modified w/ some factory add-on or aftermarket product."

No idea whether or not any kind of fix is available, given how aggressive the aftermarket parts market is one might guess there is. Guess, not.

In any event I don't drive a C7, but I have driven a Cad CTS Turbo 4 w/ an A8. As an old Torqueflight 727 fan I have to admit the A8 I drove was the smoothest, most responsive AT I'd ever experienced.

Was & remain duly impressed w/ the A8 design w/ one exception.
The seemingly persistent & nagging issues its had as reported here time & again.

My only question is WHY GM's powertrain team didn't solve the problem(s) years ago. Replacing TQs, flushes, reprogramming has to be taking a huge bite outa GM's profits.

Ordinarily I wouldn't care about GM's profit, but it's those profits which finance next generation Corvettes as well as all others in GM's product line where the tech is used.

I repeat.
People paying the kind of premium for the privilege of owning America's premiere sports car aren't dumb and IF they have what they consider repeat issues if they in any way can, they dump it.

More than one ding on a GMVIS while under warranty, for A8 or any other problem, I'd pass.
To me such data indicates dealer(s) could not rectify issues.
YMMV

Previous owner may not have ever experienced it as he was a cruzer. That doesn't mean you will not. Pretty much it you track a pre 17 A8 hard it probably will over heat. The 17's addressed the issue to some extent but was stated by Tadge that if you want assurance your 17 (and after) Z06 will not overheat on the track get the M7.

There are aftermarket coolers for the pre 17's but I don't think they address the tranny over heating.
