I made the right decision. This thread wasn't started by me, it was started by people curious if the C8 is a reliable platform or not. It's awfully funny how quickly public opinion turns from sympathy to animosity when you purchase something else, then point out the issues and the reliability of the previous product and try to warn others so they don't make the same mistake.
God forbid the C8 isn't the golden goose we all thought it was.
This is pretty much my final post on the subject. It's perfectly obvious that you all are so emotionally invested in the C8, you'll deny the platform is faulty, then cry foul when others like me have had horrific experiences like mine. In the two decades I've been buying cars, I have never had such a nightmare like this. People will take the information from the forums and make their own opinions.
Trying to paint someone as "manic" when the stress and the anxiety not to mention the lost PTO and time (4+ months) dealing with this is just inexcusable. No one should have to go through this. No car is worth this kind of headache. Period.

Are there transmissions that fail? Yes - Does that somehow make the whole car faulty? No - it makes the transmissions faulty. As far as assuming they all will eventually fail? That is just crazy and you either know that deep down or you’re delusional.
Based on volume of the c8s on the road it’s at worst 10% and likely much lower. Just accept that you had extremely bad luck and a sh*tty dealer and stop annoying everyone here.

You definitely are manic and need to stop saying batsh*t crazy things like the “platform is faulty” or implying that literally 100% of these transmission are going to fail.

40+ cars in 2 clubs, one Z06 had an issue, one C8 had an issue. Bot were fixed, but the owners lemon lawed them - and purcased another C8 go figure
*..
One dealer here screwed up 2 other cars.. both replaced by newer C8s.

And here lies the issue. I purchased a second C8. I loved the car and the platform. It was my dream car I wanted for 5 years ever since they announced the C8. I've owned a C7 and drove it for years and 3 Camaro's too. It's not like I suddenly flipped on a dime, found a different car and am now bashing the C8 just for the sake of doing so. It's taken 4 months and a lot of hell and heartache to admit that the C8 is just not right for me, and it's not the right time to own one and too great a risk with the DCT issues. No matter how many times you get in one, once a DCT fails it's always always in the back of your mind that it'll happen again.

Please don't buy another one, or even go for a ride in a friends C8. Switch dealers, switch brands, switch forums, maybe a fresh start would be good for you.
Just trying to help. If I had all of the bad luck you had, I would move to a different city and change careers also.

If I compare the C8 to neighbors daily drivers, the C8 has less issues.
Toyota Lexus and Fords - all issues. the Geep's don't even think about one.. Wifes Subaru = pure junk.
A few C8s have over 30k miles and no issues.
But the car is not for everyone, based on my daughters Lexus and the issues I would never own one.
I bought my 2023,12-23, museum delivery, 19 hour ride home, 15k+ miles no issues. I have the extended warrantee for 9 years, so no worries. If it breaks, they fix it or I lemon law it and get another. I'll drive my 67 or 72 while I wait for repairs, and daily drive the20 year old HHR with 150k miles that has been trouble free.

you seem to find fault in everything: The dealer, the sales transaction, the down payment, the car, the warranty, the dct. I think you said it best here. "c8 is just not right for me"
please don't buy another one, or even go for a ride in a friends c8. Switch dealers, switch brands, switch forums, maybe a fresh start would be good for you.

Oh yes the DCT is so incredible it shat itself at 8 miles on my first car and then almost stranded myself and my Partner on New Years on another brand new C8 at 3000. These DCT's won't even make it past the power train warranty before shitting themselves, and no garage queen's that don't get driven do NOT count. Actually drive the car and watch the transmission blow up and then good luck fighting with GM.
You've all been warned multiple times. But if you want your down payment/cold hard cash held hostage go right ahead and pull the trigger. It's not a question of if the DCT will fail, but when.

My 25 Z06 transmission failed with 625 miles on it. It has been in the shop since Dec 19th. Customer service is useless, as they can’t help with anything. All I get from them is that they are waiting to hear from the dealer. Parts take weeks to get, and when they arrive, the technician has to wait on GM to review and approve each step. This car is a nightmare. Never had issues that take so long to fix with other cars. GM held all the 25s for a QA hold at the beginning of the production year, yet I have heard of many other 25s having the same problems.

I think what really rattles people is that the DCT issue is obviously systemic and there have not been any 'new' parts to possibly fix the issues as far as we know. Only new case. Also, we can only speculate if the design is flawed or if there's manufacturing defects. The latter can be excused and then you just play the statistics but if the design is flawed then the DCTs are basically a russian roulette. In the abscence of real information, there will be questions.

The pan redesign was nothing to do with the issues a few are having with the DCT. I personally think it's blown out of proportion (the % of people with the issue, not the severity of it to those that have had it happen). Look at how many have had cable problems with the HTC.
