What preventive Maintenace has been done so far? DCT external filter changed? DCT fluid drained and refilled? Thanks.

 

The filter was changed according to the manual.
I believe they change the fluid also at that time....the first one is free as you know.

 

Oh wow, I'm on the fence to get a 2026 Z51 but after reading all this lol.

 

A lot of people have the dealer reflash the DCT controller and it goes away.

 

So the DCT filter has been changed by the 6600 mile mark?

 

Was at the dealer today to speak to the service advisor about the 3 year DCT service. He told me they just replaced a transmission on a 2023 with 55K miles under warranty.

 

In 2023 I scored a ZL1 Camaro with a 10 speed slushbox...if ever there was an obsolete description of a modern automatic.

I was pondering a "trade up" to a Z06 Corvette. Not anymore.

 

Per your 2024 Owners Manual, "If the canister filter is replaced more than 800 km (500 mi) prior to the initial 12 000 km (7,500 mi) breakin period, the filter still needs to be replaced again within 800 km (500 mi) +/- the 12 000 km (7,500 mi) service interval."

So if it was replaced at 6600 it has to be replaced again between 7000-8000 miles to comply with the manual. GM is very picky about this, having sent a letter to almost all C8 owners reminding them of this specific requirement. Also, fluid is not normally replaced at that time - its only a top-off for the fluid lost when the filter housing was opened. Your fluid is to be changed when the fluid life monitor says so, or 45000 miles, or at least every three years, or every 24 hours of track use, whichever is first.

And finally, since you have a 2024, your free services are split. You have 2 years to claim the free oil change. You have three years to claim the "free" DCT external canister filter replacement, but according to the bulletin, you must also have at least 7000 miles to get the "free" DCT filter change service. The free service does not include fluid replacement. I think the free service split was announced after the start of the 2024 model year, so some 2024 owners may have claimed the "free" service prior to the split. And, there was no minimum mileage associated with the combined free service.

Thank-you

 

1st time I have heard driver error. I was told these DCT-8 that a driver can’t hurt them.

 

it’s not a big deal until you are part of the 5%!

 

Exactly. Paying $85 - 100k for a car and experiencing a transmission failure is A BIG DEAL. IMO GM made a big mistake going with Tremec. ZF would have been a better choice. YMMV

 

Worse part is you never know when it’s going to happen! Make sure you get an extended warranty if you purchase used, if that’s even possible.

 

I traded out of my 2022 ZR2 Silverado because of the 6.2 recall. I hadn’t even been called to have the inspection done as of the time I traded it off. I had right at 22k miles on it. That truck stickered in the 80s. It had every option. I took it in the rear getting away from it and I let GM know about it. You can send an email to the address for Mary Barra. I got a phone call within 10 minutes of hitting send. It was just an “Executive Assistant” that called. During our communications her email responses never admitted any wrongdoing in regards to the significant loss of value, of course.The C8 I traded it in for was a 21 with only 1400 miles. It’s a 3LT Z51 that was over 100k new. If I do my part and maintain the car the way I’m asked to do and this thing gives me problems I will lose my ****!

 

Epilogue on C8, 2024 Z51 Transmission Failure
(1) My car's transmission was fixed after 29 days! Isn't that interesting. GM was a significant part of the incredibly slow process.

(2) I had a chip in the windshield less than an inch. When I picked up my car it had spidered the entire width of the window.
They didn't tell me. Of course the dealership said it was NOT their responsibility. They did give me a loaner car for the month.

(3) I got an offer from GM to repurchase my car yesterday! I am going to see what they offer.
Will they include the cost of the clear bra and sales tax?

(4) I did get two extended warranty bids (pretty reasonable from rec sources on Corvette Forum) but it's a GM product! Will private mechanics be willing to jump thru hoops to take the insurance? I really do not want to get in bed with my local dealership for the next 5 years. I am having my car evaluated for PTSD after this ordeal.
Suggestions? Experiences?

 

Might be time to move along! These accounts are disturbing!

 

I am meeting the Service Mgr at the dealership closest to me this afternoon. It is City Chevrolet in Charlotte NC, the flagship dealership for Rick Hendrick. I bought a 2006 Z51 from them and they were great. I only used on service writer and developed a relationship with an experienced Corvette technician then. I want to see if that is still possible 19 years later. I don’t currently own a Corvette and never owned a C8. My main aversion to getting one is wondering if it could be maintained properly at a dealer. Am I wasting my time or is it possible. City Chevrolet has a great reputation and Rick Hendrick has a private collection of rare Corvettes, many VIN numbers 001 or 002. I hope to meet a qualified technician that makes me feel good about how a future car might be cared for here.

 

I am so interested in this as I too am in Charlotte but NW up near Mountain Is lake. Dealers change sales and service personnel constantly and what was good or bad last week may not be this week. That said I will never use Victory or Gastonia again. Not just bad service but actually lying to me about what they would or did do. I used to use Parks at the lake and if I had to go to any I would probably go there. City has never treated me well when I went in there either looking to buy a car (they usually did not have what they said they did on their web site anyway) or service, just seeming like they couldn't be bothered with me.

 

Dump it. Life is too short to deal with these aggravating issues. I seriously doubt if things will get any better in the near future. At my age I'm reducing my daily stresses. The dealer network is just not competent in servicing and repairing the C8.

 

I get the impression that sometime the dealers are trying to get you to take your problem elsewhere. It appears they do not want to work on these cars.
