Thanks that is helpful. Are there other mid-engine cars that are more reliable? Porsche 911? Audi R8? IFerrari's are notorious for having a lot of issues as well in terms of maintenance. I am torn between the low entry price point for the c8 vs. paying up. In this case, is the age old adage true? do you get what you pay for?

Porsche issues stop sale due to engine issues
It happens. Don't know if Porsche is any more or less reliable, I've heard good and bad about them in that department but they definitely have their share of known issues. As to Corvettes, though generally Corvettes have a good reputation for reliability...but here we have a first-year model with all new, well, everything.
But automakers generally react to this stuff and fix it as they go, and if you order now you'd probably be getting a MY2022 model, so a lot of these issues should be worked out by then.

I’m picking up a 2020 C8 next week and it falls within that range. Hopefully the odds are against this anything like this happening. Will be driving it 2.5 hours back home. I’ve been hearing about the direct injection noise that some of my OCD brothers are hearing from the engine bay. Other than the check engine light and the motor going into limp mode does anybody know what the ticking sound difference is between a broken valve spring and just the normal sound of the ticking sound of direct fuel injection?

Wow I wish this wasn't happening, but it is nice to know GM is taking care of problems!

At least with the Corvette you will have different options to get it serviced. I owned a Porsche 911 for 15 years. Got tired of only having one dealer who scalped you since it was a monopoly. The same is true with Ferrari and Lamborghini. Their maintenance schedules are ridiculous along with their parts. If you want a car to show off in the driveway but never drive buy one of those. You’ll still have the 3 or 5 year maintenance schedule even if you don’t put any miles on it. Don’t get me started on the cost for a new clutch! The Porsche isn’t worth the $120,000 plus they are wanting these days. The Corvette is a car you can actually drive.

2020 C8 of the Year Finalist - Unmodified
Question for everyone, with the 2021 MY nearing end of production, is it safe to say that most of the major first model year issues have been addressed, (i.e. valve springs). I know there will always be unknown issues that arise but is there any logic in holding off for a 2022 or is the 2021 a stable car?

I just had my brake update done.
@semperfi1946 it was 38 cars in the first 3000 VINs. Stop the bullshit.
They replaced the entire brake booster. Has to wait on new tank as seal isn’t a serviceable item.

Starts but won’t idle
Car drove fine in evening. In the morning, car cranks a lot longer than usual and starts. Runs a few seconds, starts to stumble and then dies.
Has 7200 miles. Had oil changed a couple of days ago. Been running fine. Midway through a tank of gas. Temperature outside is about 55 Fahrenheit but wet.
Fuel filter?

These days it could be a number of things since the computer can shut the engine down if it doesn't like something.
Does the check engine light go out during the few seconds it runs? If not, there is probably a code stored that could give could give you a hint.
But it really doesn't matter, it sounds like your car is getting a ride to the dealer shortly.

Thanks. Good idea. Did that and received code P12A6. Recommended action is service within 1 day.
Went ahead and retried to start. Engine cranked longer than usual but started and idled down like normal. Problem appears to be gone but CEL on now.

Transmission
I purchased a C8 2021 and driving out of the dealers lot had the transmission fail with 8 miles on the car. The transmission was replaced under warranty, took about 3 weeks. They said that this was not the first time it had happened. Car seems to run fine now, will update if any issues.
