That sux, I have been a shop owner and technician for 36 years and we are having part quality issues like never before, even gaskets.
Example, I did a oil pan gasket on a 4.0 explorer for a good customer 8 months ago, it came in leaking last week. When i did the job all surfaces were cleaned with alcohol, i used the oem gasket, even used a new pan from ford and torqued it all to spec and it still failed, just a bad gasket. But this is an example of the crap out there.

They didn't diagnose it as a timing chain cover leak, which there is a TSB out for that. I just assumed it was an oil leak since I was down 1.5 quarts of oil(which seems to be more of my driving habits than an issue with the car) and there was fluid on the aluminum belly pan. It didn't smell like oil but it's hard to tell sometimes. So, when I finally got it to the service department and got the covers off, he found it to be the transmission filter housing leaking. I don't know what parts are required for the repair, one of which will be a new filter since he'll have it all opened up anyways. They didn't have any filters, or the parts needed to perform the repair. So he buttoned it up for now. It will still leak but it's more of a slow seeping leak. He put a little extra fluid in it for now. It most likely won't be repaired till spring as I'll be putting it away for the winter very soon, unless the parts come in quicker. There was no ETA.

Not much you can do except drive it until it fails. Technically there is nothing wrong with it, it just doesn't sound like you want it to. I think it sucks for you but maybe just sell it or trade it in?

Sorry to hear about everyone’s issues and I can empathize with your frustrations. A couple of thoughts. First, it’s not just Corvettes, I bought a new 2022 GT500 Heritage and while driving it home from the dealer (Key West to Orlando) it leaked 3.5 quarts of oil. Smoked like it was on fire. Took it back to Ford 3 times but was never repaired and continued to leak. Ford finally issued a warranty recall that required the front of the engine to come off (bad gaskets on valve covers, front engine gasket and spark plug gaskets). I bit the bullet and ended up selling the car for a loss before the recall was issued. Secondly, The regular Corvette, ERay, Z06 and soon the ZR1 are very technical machines. The engineering and electronics are state of the art. Everything has to work perfectly and the parts are made in numerous countries around the world. Unfortunately, wether it’s the Corvette, the Ford GT, the new GTD, a Ferrari or any other high Tech sports car, you can and will experience some issues as time goes on. The sad part is that Chevrolet and Ford do not train their technicians to handle the level of complexity found in modern sports cars. From experience, Ferrari tech are usually highly trained to work on their cars. US manufacturers need to catch up. Good luck to all of you working on getting issues resolved.

That hasn't been my experience. More than once a Ferrari tech has almost destroyed my car. I let them work on it twice in 24 years. The first time, complete incompetence that I had to fix. They couldn't figure out what was wrong and gave the car back to me with loose lug nuts. 2nd time was a seatbelt recall and they almost blew up my engine. I got in the car to leave and when I went to shift from 1st to 2nd the throttle stuck the floor. Needless to say F mechanics will never work on my F car again. They are no better than the guys at Grease Monkey.

Totally agree. So bad in fact I’ll never buy another Ferrari (plus the new models are an assault on the eyes). Two different dealers damaged my F8, the second caused me to forever part ways with the marque.

I can be added to the list of engines coming out.

Check engine light with the following codes:
P0020
P0021 (pending)

Shop said the Cam actuator isn't moving when commanded by the computer.
Equinox loaner is nicer than I expected, just have to ignore losing about 480 HP....

Please post up and let us know how it is. The shop looks clean and well-equipped with all the right stuff for the job at least.

Criswell? Nice to see they can do the work only removing the trunk lid and not the roof or tonneau. Please tell me they put a blanked on the roof to lay the trunk lid on? Nice to see they didn't break the rear brake line circuit at all and spearated the lower balljoint. That's the way to do it, seen some not do it that way for some odd reason.

Default Bad ignition coil, cylinder #5 misfiring, car shudder

Let me say my 2023 HTC Z06 has been largely trouble free and included 3 trips to VIR without incident. Car now has 8000 miles or so. I love the car and it has exceeded my expectations. Roughly 3 weeks ago when my family was in town I was taking my sister for a ride when the car stared to have a slight shudder and check engine light was blinking. Got a text on my phone that read something like engine/trans problem detected have car serviced. I live in Apex NC so Hendricks Chevrolet in Cary is where I have my service done. Sadly the car has been there now for 3 weeks and I have had to escalate the issue with GM. I will try to explain what is happening as best I can (I am not a mechanic).

The car was flat bed towed to the dealership on November 4 and there it has remained. They diagnosed the problem fairly quickly (within a couple of days) as a bad ignition coil. At first, they couldn’t order the part without authorization from GM engineers it was a “restricted part”. After making the tech check several other things on a TSB about a loose ground wire they agreed a new coil was needed and released the part. UNFORTUNATELY they did NOT send the two specialized bolts that are also needed that include an insulator. There are two of these specialized bolts needed to affect the repair, an upper and a lower. The tech even resorted to trying to remove the existing to see if they could be reused without success (it just started damaging the part and this s a knowledgeable tech and service shop). Finally 3 weeks later the upper bolt has finally arrived at the dealership without explanation but still no lower bolt and the part cannot be ordered (problem with the parts catalog this has been verified as being true by separate top dealership. So my F ing car stuck in purgatory over a $30 part. Dealership service manager has escalated with GM division rep, dealership parts dept escalated it as well weeks ago. Finally, I opened a case with GM myself a couple of days ago. The dealership has limited space inside but they were pulling it in every night until the tech told them car was running so bad not to do it anymore so now the car just sits outside instead of my garage where it normally is.

I live in NC so don’t know what the lemon law is regarding time they have the car without being able to affect a repair. In a few days we will be over a month. I don’t regret getting this car at all and I will never sell but if lemon law becomes an avenue I would just buy a new one - to me - the car is that good. Sad this repair situation is being handled so badly by GM. I am putting it more on them than the dealership at this point

That sucks, but it appears NC has a very friendly lemon law. As long as you haven't had the car more than 2 years or 24k miles, its eligible for the lemon law after a mere 20 days out of service. So you can already go that route if that is what you want to do.

Mine has been out of service more than 30 business days in five months. Exploring options including lemon law as it qualifies for it by a wide margin. It’s really disappointing to spend so much on a car with issue after issue. Debating on taking the money and running or getting a 2025. I can let you know my experience if
you decide the lemon law is your path. Its in GMs interest to work with you as in lemon law cases, Gm typically has to pay your attorneys fees as well.

The chances of getting two lemons in a row is pretty small. I'd vote for the 2025. Will GM work with you to get a replacement, or has that not been discussed yet?
