There seems to be two camps on the DCT issue:
1. People who still justify their purchases and think "it can't happen to me" so, they try and marginalize the wide spread DCT issue as a "bad" experience or "bad" luck.
2. The rest of us who have had DCT issues and see no long term solution or traction on this issue aside from dumping the platform altogether and getting into something else like I had to.
Mind you, I have spoken with so many car people and vette people I run into and the #1 topic is the transmission and the other horror stories I get to hear.
Just because people might be Vette fanboys does not excuse GM from building a faulty product and making the consumers suffer for it.

Not sure what this means, but doing research before buying a car is not wearing a tinfoil hat, especially for those who are spending close to $100k on a car. After owning many cars, this is the only car that has left me stranded in its first few hundred miles. I’m sure if you have to replace a transmission in or out of warranty you’ll enjoy the experience. I don’t sit and worry, but I also don’t minimize anyone’s concerns because they are valid.

Literally. Every single time I took the cars in for this problem there was Z06's and non Z06 C8's at Fremont for DCT replacements. And you've only driven your 2020 4000 miles in 5 years on average. I actually drive my cars and daily them. Again, "bad" experience doesn't begin to fing describe it. The C8 is a bad product end of story. Or feel free to roll the dice, I hope you have an extended warranty for the powertain because boy are you going to need it. It's only a cool 20 grand for a DCT replacement. Again, it's only a "bad" experience for someone else until it is YOU that has to deal with it.
You're not taking this well at all. It's just a car, assembled by humans who often make mistakes.
You're in the minority on this one. I hope you're no longer driving a Corvette.

Stop apologizing for a shitty product and shitty dealerships. People who have had this happen to them are shouting from the mountaintops trying to warn you all so it doesn't happen to YOU.
Consult a Therapist indeed. When your vette takes a dump don't come crying to me. You've all been warned. Roll the dice and see how long it takes till you get burned.

Would you take it well if a dealership stole part of your down payment? Would you be taking it well if you were dealing with the same issue on a car you bought 4 months ago? Please by all means pay for the Therapist, and I am no longer nor will I ever drive another ******* Corvette. You see how well you take it when there's over 60 grand in your money tied up in lemon cars and buybacks and the dealership ***** you on the first buyback to the point to where GM even has no explanation and you have to consult a fraud attorney.

That **** is messed up. I don’t blame you one bit for being angry, if that happened to me or anyone else here, they would likely feel the same way.

Again, I'm not trying to get into a pissing match with other C8 owners, I'm trying to warn people so they are not out their down payments and dealing with the hell I've had to go through. Had I'd known just how wide spread the DCT issue was on these cars back in October, I would have never bought a C8 to begin with. The car started as my dream car I wanted for 4-5 years, and mind you I've already owned a C7 and 3 Camaro's prior to this. I won't purchase another GM product ever again.

There’s no harm in making your situation public for information to guide others in making their decision.
There is a problem with condemning every product produced because you experienced a problem.
Get rid of the problem and move on.

Yeah two camps and due to your experience you feel everyone is out to get you. I get it and I had sympathy through your experiences. But not anymore. I'm tired of both the negativity towards GM, Chevy, Corporate, the Dealers and us as owners that have not had any issues. Also tired, got tired very quickly, about your Toyota.
Two camps, those that haven't had issues and those that have. Don't marginalize us and we won't marginalize you.

Good on you to feel like you don't have to wear the oh my god what if "tin foil" hat. So which is it then? Are all C8 owners with DCT problems conspiracy theorists now? Or do all of you still refuse to acknowledge this platform has glaring issues that GM refuses to fix?

And with regards to the $20K DCT replacement cost, that is another internet rumor started by people guessing the cost. Someone actually posted the DCT replacement invoice and the total DCT replacement cost was around $12K (it was a little fuzzy since the total invoice was higher but he had other things done). The actual DCT cost was around $7K with the rest being labor.

Pick any car, built by any manufacturer and find a forum or discussion group for that car. I guarantee there's a version of "jazyjason" there.
Here's the thing....the car comes with a warranty. All new cars do. You can either let them fix whatever the issue is and sell it or decide to keep it. Eventually they all have some unexpected issue. I had bad experiences with a BMW M440 and a Lexus IS500. Neither of them caused me to go online to tell everyone to avoid the products. They were repaired and I moved on. And yes, I now have a 2024 Corvette that has had zero mechanical issues to date.
By the way, having your down payment tied up with the dealer has absolutely nothing to do with the vehicle. I hate that you had to go through that. Sounds like your issue is with GM.

Also, lol I love how the second you say someone's car might be "faulty" or have issues, people suddenly turn on you. I get you all are trying to convince yourselves that you too won't be burned on your 100k purchase, but personal biases has nothing to do with the systemic issue C8 owners have had since 2020 regarding these transmission issues.

You must be blind as a bat if you cannot find the two discussion threads I started months ago regarding the first C8 and then the second. You can find all the history and reasons why the car is "shitty". Plenty of explanation.

Call me blind then. I was responding to your post directed at me asking how I would feel if my down payment was stolen by a dealer. Again, that has nothing to do with the actual car.
I'm not about to read every post you make about the issues you had with your car. But I commend you for buying a second car after you were "burned". I can't say that I would do the same.
Again, get it fixed under warranty and make your decision. This simple logic will save you from stressing about things you can't control.

It's time to just move on and enjoy your Toyota. It's perfectly acceptable to post reasonable responses but your threads are full of manic posts where you freaked out and decided to quickly lemon two different C8's rather than just getting them repaired. Then you find out your dealer screwed you over after the second buyback. Your problem with your dealer is not the problem of the C8. I am sure the majority of C8 owners are sympathetic to your situation until you become belligerent with the slew of nasty posts in any thread you can find. Get a lawyer to sue your dealer for negligence in how they handled the buyback and refund of your money and move on to the supra forums for reassurance that you made the right decision.
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.

I bought the second car as a replacement for the buyback, and was lied to. The dealership assumed the new C8 would be problem free. It only came to light after the second C8's DCT failed and GM agreed to the second buyback. When GM was writing the buyback offer and wanted me to sign, that is when we all noticed that the dealership did not follow the buyback protocol. You telling me to get it fixed under warranty is just a cop out to GM, when people who have had replacement DCT's have had those fail too. One poor guy had a 2020 that has been in the shop for 5 separate issues and that was after the DCT replacement.
No cop out to GM. I have no loyalty to any brand. I'm loyal only to my accounts.
Over 150,000 cars are on the road and a few have had transmission replacements done. Would I feel the same way if I were you? No! I'd get it fixed under warranty and move on.
Another post mentioned you have a Supra now. Nice cars; I enjoyed one for a while and later decided to sell it after dealing with Toyota dealerships inability to obtain the "BMW required" oil to do simple oil maintenance. I hope things are better on that side these days.
Good luck.
