I feel bad for the owner. He got screwed three times.

1) he paid $50K over
2) his car has a major issue in 50 miles
3) he has to deal with Chevy service.

He knows nothing about the car and there is no information about anything other than a check engine light. I have no idea who he is but he is not at all worth watching.

I skipped around and did not want to put 29:00 minutes into him. A spent about :30 seconds on it and that was enough. Hopefully someone can provide some real information.

That sucks for sure. It'll be interesting to see what the problem is.

When it comes down it it, this is what warranties are for. Until there are enough on the road to see if the car has some stupid high failure rate for the engine or DCT, I'm not thinking much about it. The last new car I bought was recalled for some pretty major engine surgery to address engine failures, so I've been down that road before.

To sum it up the engine is knocking and it sounds like a valvetrain failure at only 50 miles.

I fully agree that any new car can have issues, however GM claims that this engine is dyno tested to ensure everything is working as intended. With only 50 miles this must be a parts failure within the valvetrain, which poses the question of what kind of questionable parts are going into these engines. If you recall some of the 2020-2021 Stingray's had valve spring issues. I see a possible trend of failing components.

Another member posted a claim (in general discussion) that his dealership has a brand new Z06 in need of a DCT. Unsubstantiated, but who knows.

They didn’t cheap out on this engine, sourcing parts from some very reputable and respected vendors. I’d be more worried about DCT failures than LT6 failures early in the ownership experience.

This does not indicate a possible trend.

How do you know who or where they got the parts from, did you personally issue the PO#?

How mad would you be if you were that guy, paid 100K in ADM to get a car early and then had to wait 6 months for a new engine? Even worse it looks like it had the **** scratched outta the wheels the way they strapped it down on the tow truck. And it's black so after it spends god knows how long sitting outside BFE Chevy, being leaned into, worked on, bird bombed and walked past his paint should be just about hammered ****. Then once it's fixed every lot rat gets to take a turn behind the wheel for 'drivability testing'. That guy is living my greatest nightmare.

They’ve announced some of the suppliers. No need to be an insider. For example, pistons from CP Carrillo and rods from Pankl Racing (think both of those are owned by the same company).

Ouch. This was very sad to watch. Blue smoke and rod knock means that engine spun a bearing and already bent a rod. Unfortunately, it's one thing to claim to mass produce a FPC 5.5 liter 8600 rpm engine, it's a completely different thing to actually do it. We have been singing this car's praises before putting it through its paces. The tolerances in a high compression engine like this is so low that slightest build error or supplier issue with parts and you have these types of failures. Ford has paid a dear price for trying to do the same.

On a side note, when people compare Corvette to Mclaren or Porsche or Lambo and say it's the same car at a fraction of the cost they miss that when it comes to comparing car A to B one must also compare things like OnStar experience as well as dealership not accepting the car when they are closed. This whole experience would have been completely different if this was a failed Aventedor or a GT3. You do get what you pay for.

Hopefully some people come back to reality and drive down these insanely high ADMs for such a hyped up car. Some of these problems are good for the greater buyer market as it will balance some of the insanity.

Well, by my count we now have 4 documented issues with Z06s. 3 transmission failures and 1 engine failure in some 200 odd deliveries. That gives you roughly 2% failure rate at such an early time frame (cars are very new). I'd say we need to give it till June to really see how well/bad this car is. GT350 failures didn't really show their true color until after 6 months.

Are you calling a check engine light for the DCT after doing donuts and a failed transmission pan gasket transmission failures, or is there something else out there?

Yes there is other information. The Z is up on the the flatbed rattling like it has internal issues. If you want to totally ignore that, well I guess that’s your prerogative. To me its concerning especially since Im ready to give them 140K.

I had the motor in a 2021 Camaro ZL1 1le fail at 65 miles. Not a Z06 but it happens.
