so my 2024 Z06 is at the dealership with a seized engine at 2600 miles. they are going to be putting a new engine in it. My question to the group is will the value of the car still be the same ? If there were 2 for sale side by side mine with a nonfactory engine and one that has had no repairs done which would you buy?

It wouldn't bother me since the motor is being replaced by GM.

There's no numbers matching like back in the day. If it didn't show on Carfax and the engine is replaced there would be no way for the new owner to know unless they did a VIN check or the owner shares the info.

I'm guessing you have to do the 500 mile break-in over again? That would be the worst part!

Both engines were built and tested at the same place, and are identical, it is only the installation that will be done by different people. I wouldn’t think that a Corvette specialist with experience is significantly different than an assembly line worker. Plus, the engines are not serial number matched to cars, so how would a buyer even know about it?

Probably wouldn’t even know. Either way, does it matter? By that I mean she’s worth A LOT less as she sits, so it’s not a question of if you are going to get the engine replaced or not. I doubt lemon law is a factor since they are going to such great expense to fix her.

Years ago, my wife and I bought our first “family car” for her, a used 300M. It was a factory rebuilt / replaced everything under the hood. It was at a discount and disclosed because it had been a manufacturer buy back. Anyways, she was bullet proof. Changed the oil on her and that was the only thing we ever had to do to her.

I doubt it’ll matter resale wise, I had one replaced on a GT350 and I still got the market rate when I traded it in. I would ask for a long bumper to bumper warranty, never know, they might do something like that for compensation for the car being down.

I can tell you this, a local dealer to me has replaced over 15 C8 Z motors already! That is a scary car to buy for me right now!

Wouldn't affect value to me in the slightest.........new engine, original engine, wouldn't matter as long as it works.......

hamta

i have an extremely hard time believing that statistic. Who is the Dealer and where did you get that information?

Ask them for the opportunity to build your new motor. Tell them you can be at Bowling Green with a weeks notice. It's the least GM can do for you in this situation.

Would not impact me buying your car at at all with a new motor.

The real issue is reliability of the car, in general, from the transmission and engine standpoint. I have 2 '23 Z06s and one is going to the dealer with a dreaded P0700 Transmission Control Module tomorrow. My car was "bricked" and would not start after getting it off the Road Atlanta racetrack on Saturday and filling gas at the gas pump at the track. It took me two hours to get it started so I could get it on my trailer and drive home 650 miles. Looks like the codes show it has something to do with emissions within the TCM module. The dash message was "Drive to a safe place as your car won't start". This must be a programmer joke! Makes no sense at all. When the car runs--it is awesome! But when something goes wrong--holly heck it goes wrong so it seems.

The issue is the competency of the technician and if they take the time to do things right. The job isn't rocket science, but most techs are about speed to make money and don't torque things to spec and they don't worry when clips or electrical retainers break. Many love to say they only use a torque wrench on torque converters and cylinder head bolts, but as someone who tracks my cars, torque values on driveline/suspension are just as important. Leaving the rear UCAs loose, or conversely nuking them into the aluminum frame holes are both unacceptable outcomes, but most tech's just run them in with an impact gun... that kind of stuff.

Mark2021C8

Don't know if that number is correct or not but I believe the failure rate of the LT6 and DCT tranny are higher than I would like. But these cars are an absolute blast on the track! So much so that I am now buying a third C8 Z06--yes I will own three as the higher failure rate does not bother me because the car is awesome. Atleast under warranty GM will replace motors and trannies. And they are acting like Porsche since I know a person that seized a Porsche motor at COTA on the track this year and Porsche is replacing the motor with no questions asked.

ATC399

Did you buy it for the resale value or to enjoy?...idk side by side I would take the one with the engine installed at the factory...period...most dont trust the dealer techs to change the oil...jmho...God speed OP

hamta

The true failure rate we'll NEVER know. But I agree, even 1 failure is too many, especially if you're the one! All I know for a fact is my 2021 C8 SR was flawless after three years and 25,000 miles. I only have approximately 2,000 miles on my 2024 Z06 and they have been perfect, with absolutely no problems. I couldn't be happier (at the moment). Here's to good tidings to all with their C8's and hope that they have plenty of trouble free miles!

If I were in the shoes of a buyer, if the new motor had enough miles on it to prove itself/shake out any issues, I would have zero concern buying a car with a replaced motor.

Will not happen for several reasons.

BigVette427

PBC couldn't handle the volume it sounds like.

Last used car I bought had the engine replaced. I had no idea as it wasn’t in the carfax yet. I figured it out during the first oil change I did.

I was annoyed for about a day. Then I realized that overall it was a positive thing and was fine with it.

Im more afraid of carfax reports that have regular entries for “electrical system checked, battery replaced” several times a year than a replaced engine.

Racingswh

A replacement engine wouldn't matter to me at all. I have had 3 so far and it's never mattered as it pertained to the resale value of any of those vehicles.

I have been asking this question to myself lately and don't know the answer and wondered if anyone here might have some idea. How many engines and/or transmissions will GM replace until they say "we aren't doing that again?"

The only thing I really use a car for is HPDE at the track. I use trucks and SUV's as my daily transportation. Can I pop an engine or two in a C8Z and will GM just smile, cover it under warranty and tell me to bring it back when it happens again?
