The thing is, sports cars in general, especially those closer to the edge of the performance envelope, are typically more problematic than regular cars/SUVs. Porsches in the past have had bore scoring in the engine and other major issues, so they're not immune...I know for sure that the Cayman and 911 have a number of recalls and have had their fair share of issues, Consumer Reports for example gives the 911 an expected reliability rating of 3/5, same for the Cayman, so they're not stars in this dept. Otoh, they gave a C8 a 1/5 in this department, which is pretty harsh but this is imo due to this being an all-new platform with all-new drivetrain and so forth, vs the Porsches which are incremental improvements on incrementally changed designs. If you go back and look at points where Porsche introduced something all-new, they usually also had quality issues (i.e., bore scoring, PDK issues when it first came out, etc). Also, Chevy will warrant the Corvette if used on the track (only Z51 and presumably the Z06 variants (Z07 only? dunno)), whereas Porsche most emphatically will not, same as MB. I don't track my cars, but the fact that they'll stand behind them with track usage where the others won't to me speaks of a high level of confidence in drivetrain strength and reliability.
Having said all that, I do speak as the recipient of a brand new transaxle on my car after the rear diff developed a noticeable whine (poor shimming of the diff), so I'm not gonna claim they're rock stars in reliability, so I'm not gonna say that GM's QC is all that great, But none of the other sports cars out there are fabulous in this area, and this one's cheap to own and service (much less than a 911 or AMG GT, which are what I was looking at before deciding to take a serious look at this), and the fun-to-drive and handling factors of this car are just off the charts. Lexus reliability (and service departments!) would be most welcome here, I agree, but I've got the factory warranty extension out to 5 years and will get an extended after that if I find the company they offer it from is good. So yeah, Chevrolet could definitely use some QC improvements to put it mildly.
Also with any new production vehicle, they only have a certain number of mules they can put out there. So if you have an issue that affects 1/1000 or 1/5000 etc cars, odds are against them catching it so definitely first few years are more issue-prone than later ones, which is why this thread is keeping active. Gotta balance that out vs having the shiny new kid on the block, I knew it was a gamble and took my chances, and I still love driving it. Amazing car for the coin, no doubt about that.
How did you get that factory warrant extension out to 5 years? Is that just for the transaxle?
So some problems with the car, you still enjoy it? It's really that fun to drive and great handling huh? So much that it outweighs the few problems. Because I still have some time to pull out from buying C8 if I want! Still deciding!!
Thanks for sharing about the 911 and AMG GT comparision, yeah C8 is really best bang for the buck. I visit the forum off and on, other than DCT, the other problems are kind of minor ones right?
If you are doing it over again on getting a C8, would you do it again?

You mention the first few years of a new generation of vehicle as being more trouble-prone but this rarely happens with Toyota/Lexus and Mazda. Remember, my 2001 C5 Corvette was the 5th year of C5.
Consumer Reports did publish an issue that included the ups and downs of German vehicle reliability. We need to abandon the mindset that this has, is, and always be inevitable.
By the way, this car will come standard with a supercharged Toyota V6. It is not really a hyper-fast super car but my guess is that its powertrain will be robust. 2023 Lotus Emira: What We Know So Far (caranddriver.com)
Another thing to consider is that often, electrical issues plague American and German vehicles. It has nothing to do with power and acceleration unless it is part of a launch sequence.
Toyota/Lexus and Mazda they don't have problems for the first couple years of their new model cars? I thought you always want to avoid the 1st year of a new model cars. I guess the QC for Japanese cars is really good. Hopefully GM can learn something from that.

Those are MRR M-755s indeed. This particular set was "high polished" & clear coated. Total price from MRR with shipping was $2,200.00. Well worth it; absolutely changes the look of the car...

I had a rattle/buzzing noise at highway speeds in my C7 Grand Sport, eventually got use to it where it didn't bug me. I pray that's the worst issue I have when I receive my C8, a twin to your fine looking machine by the way.

Correct. I am convinced that Japanese engineers more thoroughly test components, subassemblies, and their entire vehicles before releasing them to customers in the US. The problem with many GM vehicles is that issues often continue to show up for many years after the first new generation release year. In fact, many problems like the smog pump check valve and column lock mechanism (C5 generation) are never fixed.
I've worked for large companies that have a dedicated "Legacy" department. The engineers in this department investigate and resolve issues, and find replacements for end-of-life components. It appears that GM doesn't have such a department.
What kills even more is event code 4000 jail. Come Tuesday, my car will have been built 4 weeks ago but is still stuck at BGA on QC hold reportedly for the damaged wheel issue. The car is paid for, registered in my name, all taxes paid but still stuck at Bowling Green. I was so much looking forward to having it built, which it has, but now I can't even get my hands on it. I would have gladly taken 3000 jail over this.
And….your warranty start date was punched when you signed the papers! This happened to me as mine was “stuck” in QA for 5 weeks. Once I took delivery, I was fiddling with the My Chevy App only to find out my warranty started 6 weeks before I got the keys. It took weeks to get a letter from GM to extend my warranty for the 6 weeks through “good will”.

Yup, you are correct. Mine will be stuck at the plant 5 weeks as well come Tuesday. And what makes it even worse is my car will be shipped to MM where it will then be put on a truck shipped to me in California via Intercity. But that's not the worst part. Intercity only has one more planned truck heading to the west coast this year due to the holidays and my car has to be at MM by Tuesday in order for mine to make the truck. So bottom line, I most likely won't receive the car until the middle of January - 2 1/2 months since it was built and paid for. To say I am pissed is an understatement.

Well that just plain stinks….I would suggest calling your dealer now to open a case with GM as it will take awhile to get the letter. MM is a good dealer and should know what you’re asking for….just make sure if they want to solve the problem that the good will is at any Chevy dealer.

My salesman and Tommy Jr at MM are all over it. They have been great through this whole ordeal. They have been talking with their GM rep on a daily basis trying to not only get my car released, but a batch of their cars that were affected by the wheel issue the first part of November.
Did my first launch in my 2021 HTC at slightly over 2000 miles and the passenger side axle snapped. Really bummed out and now hesitant to try this again unless I'm near the dealer. Dealer replaced in two days. Said it snapped under the CV boot clamp.

Factory warranty is an actual extension that GM offers (but most dealers seem to prefer to hide so they can offer you a third party extended warranty (not the same, factory is better!) for extra profit on their part. I knew of the factory warranty ahead of time, asked for it, and still had to put up with BS from the finance dept trying to convince me that the extended warranty (aka service contract, i.e. not a true warranty) he was trying to sell me was the GM version (it clearly wasn't, as it stated service contract and was administered by a third party, not GM). So I ended up literally escalating to the GM of the dealership to get it. FWIW the powertrain warranty is...shoot, either five or six years, can't remember which but anyway is longer than the 3-year bumper to bumper, but I wanted 5Y bumper to bumper.
Trouble wise, there were some early-build valve spring issues, but those seem to have fallen by the wayside. Other than that, transmission seems to be the major one, but relatively rare (I was one of the lucky ones, I guess). Also took some escalating to get this taken care of, but it got taken care of.
Yes, I would buy it again in a heartbeat and in fact am planning to get a Z06. Love it.

So German car wise, my second German car was a CLK55 AMG, which threw a rod with one month remaining on my extended warranty. Didn't stop me from trading it in on a CLS55 once the engine had been replaced, or on a CL63 after that. Also, this was a pretty rare event, actually never heard of another AMG engine doing this so I think it was just a defective part. And our experience with other German cars has been pretty consistently choppy, although the CLS and CL actually held up pretty well. Still, would never own a German or American performance car out of warranty (or extended).
The Japanese stuff is bulletproof, my wife had an RX300 some years back for which I got the Lexus extended warranty (through Lexus, not a third party, was a great warranty, but...), never needed it. Nothing ever went wrong with that, period. But, unfortunately, the one and only performance car they ever made that I'd love to have, the LFA, was too much coin for moi, but man that was an amazing car.
Don't worry about the Lotus, it's British so they'll find a way to screw up its reliability. Beautiful car, though, and I'll bet it's just amazing to drive with the light weight.

I rented a BMW i8 for a day. As you may know those cars were in the $150k range when new. Anyway, after driving it most of a warm Summer day, its HUD was acting exactly like the HUD in my 2001 C5 Coupe - fading away from heat.
I stopped to get gas and quickly discovered that the gas cap would not unlock. I had to search the internet to find out where the mechanical pull cable handle was located. How embarrassing!
I also rented a Lexus LC500 for a day. Well what do you know, it was rock-solid the whole day. It was a tad faster than my 2001 C5 but I'm fairly certain it would not require thousands of dollars in out of warranty repairs by the owner.
The Lutus drivetrain should be very robust but I'm a bit nervous about its electronics. Its price is competitive with the C8 and yes, light weight = lots of fun.

I have to ask if they told you WHY it "snapped" and whether the replacement is more robust...........

I have the same issue with my 2022 HTC. Took delivery Oct 25th
Oh man sounds like it's a common problem, rattles and squeak noises in a brand new car 60k to 90k+......poor QC or what, maybe a combination of things, come on GM.
I have the same issue with my 2022 HTC. Took delivery Oct 25th
@Cumbers Wow, interesting. I took delivery about a week prior. Maybe a problem with a particular run of dash boards? Hey, do me a favor. If you bring yours in for the rattling sound and the dealer is able to fix it, please drop me a note and let me know what the source of the problem was....
For the "rear axle system off" problem, what's the fix for it? because some posts said it never came back after the restarted the car, some said after they added 2 quarts of fluid to DCT and it never came back again. ( It went away but 2 quarts didn't fix it, GM said you don't need it unless tracking it) So did they figure out the problem? Sounds like it's not that common?
If you go back and look at points where Porsche introduced something all-new, they usually also had quality issues (i.e., bore scoring, PDK issues when it first came out, etc). Also, Chevy will warrant the Corvette if used on the track (only Z51 and presumably the Z06 variants (Z07 only? dunno)), whereas Porsche most emphatically will not, same as MB.
