I am not downplaying anyone's vehicle issues as I know what a pita that can be, not cheerlead any dealership and how it handled your problems.

There have been over 100,000 C8's sold (Mar 2023) and no idea what the number is today.

If you read this forum you'd assume they all have issues....I get that most of us just read, observe and look at threads without posting. If we do it is about scheduled maint or where to buy an item.

Those that post have had an issue, and I understand the need to share that. It appears to have frightened off a few because there are so few positive posts and I get that too. I am not one to post how much I love the car and how fantastic my last drive was.

'23 C8 Coupe 2LT daily driver 17k.

 

I'm going with, you need to understand the transmission, and understand really slow maneuvering beats up the clutches, and keep that to a minumum as best you can

 

The good: Cheap
The bad: Cheap
The desire: Cheap
The result: Cheap

 

I really don't understand why some people that are so negative about the C8 bought it or why they still own it. I do understand there are trolls on here that don't even own one.

 

Let's round to about 130,000 units sold. Let's also assume a higher than avg overall major failure and pick say 10%. I have not seen a large group of people complaining, heck I'd barely say I've seen even 1000 unique user complaining.

I think, there is an abundance of growing pains amongst c8 owners where the car requires a little more care and feeding vs say the C7. I have not seen evidence of anything major that will happen. Comparatively all 991.1 and 991.2 Porsches will have at least 1 water pump failure. It's so bad PCNA added a part specific warranty for 10yrs/120,000 mi. I have not seen the need to do that from GM for anything on the C8.

Furthermore if there was such an absolute possibility of issues I don't think they'd have sold as many as they have to date.

 

2020-2023=134,879
2024 should end up somewhere 35,000-45,000

even if its a 2% failure rate on the transmission, that's 2697 units (2020-2023), certainly not a small number, but overall still a low percentage.

I have no idea how many have actually failed as GM doesn't share those numbers, but my gut feeling is its not 2697, but I could be wrong.

 

You missed the rather common Porsche cylinder scoring issue and cylinder 'weeping/leakage' ...the one cause by out of spec injectors that scored cylinders by negating the oil and the other simply head to cylinder leakage, then the failed IMS bearing that would destroy the engine..... this in cars much more expensive.

There is no such thing as high end tech/pushing the envelope 100% reliability except in faulty memories....

 

Only 27,000 miles on my '23, but zero problems -- other than getting t-boned... ''

All eight of my Corvettes over the past 34 years (1,000,000 miles) have been essentially trouble free.

 

Not "all".....I own a 2012.5 991.1 S PDK Cab with no issues to date. So, not "all". It is a known issue for the 991.2's but not "all" have a failure.....

 

What is this BS all about? It is news to me. I have a 2022 with 10,000 miles and NO issues. I do not in any way "baby" my transmission. This exactly the kind of stuff that the scares off new buyers.

 

While I do not agree that "slow speed maneuvering" will "beat up the clutch(s)", I believe this line of thinking comes from the fact that at low speeds there is going to be some slippage as the clutches engage, as with a conventional manual. And if one tries to maintain a speed that is lower than the point where the clutch can fully engage, then continuous slip can occur. And the line of thinking continues that with slippage comes wear. But does it, and how much? They are wet clutches and some torque is transmitted via the viscous fluid layer as the clutches start to engage. At some point the surface "asperities" start to touch and that is where some wear can take place. I do not know the exact RPM where the clutch can fully engage in first gear, but my guess is about 1000-1250 rpm. So that corresponds to between 5 and 7 mph. So if one is trying to coast along at 4 mph under engine power - then there is going to be some "slippage" in the sense that the clutch will not be fully engaged but will be transmitting some torque to the transmission and wheels. Perhaps this is a concern if one is in 20 miles long traffic jam and must coast at an average speed of 4 mph. But for normal starting and stopping its my belief that any wear is negligible. I think its very likely that a single launch control or rapid exit even will put significantly more wear on the clutches.

 

Oh I did not forget, bore scoring has always been a 911 issue in one way or another. But I kept it at a singular issue per singular issue.

Count your lucky stars if you have not had any issues yet. Even with the prevalence of water pump and bore scoring issues I still almost went back to the Pcar brand.

 

Simply not true. The 991.1 is one of the most reliable modern day 911 platforms....how many 991.1's have you owned?

 

2024 stingray, 5,000mi, never back to the dealer. Very satisfied owner experience.

 

The problem is not the failure rate.
The problem is what happpens to you after a failure.
That is the reality of the situation.

 

I think the paint chips around the headlight failure rate should be zero after GM documented the known problem which is due to improper alignment during assembly. GM is not even preventing known assembly problems from happening.

 

Still have my fingers crossed

 

A very small % of C8 owners are on this forum. A very small % of owners on this forum post. The opinions you read are from a very, very small % of C8 owners.

 

100%. Whether the issue is mechanical or not, the same situation exists - you will be at the mercy of a Chevy dealer that likely doesn’t give a **** or worse, dealing with GM directly.

That’s what has spooked me from buying my second C8. It’s a dilemma I now face because I love corvette but my customer experience with GM was on par with the DMV.

 

This auto forum is no different in that regard than others. As with everything, those who have problems say so, those who don't... well, they don't. However, this tells us what to be on the lookout for and what the chances of getting it fixed or needing to fix it ourselves might be. I'd say most here realize this.
