I caught a video from the "The Car Guy Online", covering the latest on GMC's L87 6.2L nightmare. So I though I would look at his site regarding the C8 to see what is shown about the DCT. Now, there have been quiet a few antidotes regarding C8 DCT issues on this forum. Enough in my estimation to turn folks away from the C8 just by doing some basic research on a forum before buying (which I didn't do obviously because I bought a C8). However, when looking at the site which pulls NHTSA reports (as I understand it). Very few DCT issues are reported. I'm talking single digits per C8 MY. So the question is.... Is the C8 DCT issue overblown on this forum or in general? Or, are folks just not submitting reports to the NHTSA? I tend to think its a bit of both. But, would hope if you have had or are having an issue, you would take 5 mins and submit a report.
I know of a C8 owner who had his first car bought back due to the DCT. The second C8 is on the 4th trans (first one broken, second one leaked, third one delivered with a cracked case, fourth one leaked). GM has a problem and the 6.2L issue is a tell on how they handle issues. I suspect they'll be recalling another 500K engines. GM won't fix it until the pain for them becomes too much. I like the idea of putting a sticky up to the NHTSA website to report issues.
Overblown, and I don't think that "someone that they know" has had five bad DCTs.
Everybody thinks the issue is overblown until it happens to them. I have vehicles from many different manufacturers, and have been on many different forums for decades. You know what I don't see on those other forums, people posting about a transmission issue almost daily & people still having transmissions replaced 7 years into a model run.
Corvette owners are some of the worst at accepting/admitting when an actual issue is present. Same discussions of the "overblown" C7 Z06 overheating issue. Same discussions of the "overblown" C6 Z06 valve guide issue. Same discussions of the "overblown" C5 LS1/LS6 oil consumption issue (I had 2 LS1s with said "overblown" issue).
I'm sure there are a whole host of people on the Escalade & Suburban forums claiming their engine is flawless & the 6.2L issue is "overblown"
One can love their car and still admit it has flaws.
I guess it depends on what you'd define as overblown. It's a real issue, I have personally seen several (ongoing) failures. Reported to NHTSA, who knows. How widespread the issue is is anyone's guess. IMO it's unquestionably big enough to be far outside the norm, but who knows exactly how much.
To be clear, I also think the C8 is the best performance buy on the market bar none. It's breathtakingly good. Sadly it just has typical GM development quality.
Absolutely I agree when it happens to you it's a very big deal and one that concerns me as my 2020 is out of warranty. But I think it is over blown and that when someone that has had a problem and keeps repeating it or has friends that keep repeating it that it seems like even more have had the issue.
You think Corvette owners are the worse at accepting issues. I think they are the biggest whinners about things...

Here is what Consumer Reports ratings show:
Other (probably more biased) quality ratings show the C8 has good reliability. The only place where the C8 has a reputation of poor transmission quality is on social media.
We'll see what happens as more and more cars come off warranty and they accumulate miles. When folks are facing a $20K transmission fix it'll certainly garner more attention and will make used C8 prices drop lower if this occurs. Gone are the days when a $2-3K transmission fix was in the cards. Or the days when you could actually fix it yourself. Hopefully the aftermarket will step up over time and provide replacments at less than an OEM price. I plan on keeping my car that I track very regularly and aggressively. I also overmaintain the DCT with yearly fluid and filter changes. I'm willing at this point to just enjoy the car and deal with any eventuallity.
Very few people post here saying how great their car is, the negative posts makes people think that all of the cars are flawed
My 2023 has been great. Only 1 warranty issue as compared to my other brand cars that typically had 2-3 issues under warranty. Yes, the negative posts always get posted, no one posts positives typically. Of all my friends who have C8s, few have had issues. Only has had a major issue on his eRay, where the electric motor went bad and took 6 weeks to repair. I have 5 Vettes, 2 new and had few problems, 9nly 1 minor issue between the 2 new ones.

You can currently get new OEM DCTs starting at less than $8K which isn't that out of line compared to other transmissions. How much less would it take to consider a remanufactured unit?
I agree it will be interesting to see how many people post that they have to pay out of pocket (or under an extended warranty) to get a DCT replaced. It seems most problems occur early on so it may be mostly garage queens.
I'll post that I've had no DCT problems but it is sort of meaningless since most people don't have problems. There is a guy on the "other" forum that has over 200K miles on his DCT without problems so that indicates there isn't an inherent design problem with the DCT (but he had other problems with the car).

$8K installed would not make me blink. $5K for a remanufactured unit with a warranty would be ideal.

I'd bet 99% of car owners don't know what the NHTSA is nor that they can report issues.
