My Z51 HTC with all the electronic features has run flawlessly so far after 1 year.
I could never really figure how JD Power reports can be so different from Consumer Reports ratings. I think perhaps JD Power has an industry bias versus an impartial data based approach. Interestingly Consumer Reports rates the C8 with poor reliability but very high consumer satisfaction.
No problems with my new 2022 HTC so far, but only 200 miles on it right now.

From the article. After waiting more than a year for delivery, Consumer Reports finally got its 2021 Z51 model in May and ended up giving it 97 points in the road test, five out of five points for owner satisfaction, and two out of five points for predicted reliability.“We can’t recommend the new Corvette because of its inconsistent reliability history,” Consumer Reports concluded."

I believe the JD Power reliability ratings are for the first 90 days of ownership. Consumer Reports is evaluating longer term ownership.

What I found interesting is Consumer Reports rated the '15, '19, & '21 as having much worse than average reliability but the first year C8 isn't on the list. A lot of people said they would never buy a first year C8 because of reliability problems...

My '22 Stingray has been at dealer for over week now due to an engine misfire , cylinder 6 - they say it is the fuel injector but do not have an ETA (backordered) , do you have any more inside info? or Am I in for a long wait ...
NY has a 30 day threshold for Lemon Law , I'm already at day 8 , would rather not have to start over with another car but if the biggest car company on the planet can't get me a new fuel injector not sure I'm good with the car in the long haul...
My injector problem was also on cylinder 6. Took initial delivery on 12-15-21, returned vehicle to dealer same day. Received full refund with first right of refusal to purchase once replacement injector was obtained. 3-19-22 and still no injector from factory. Glad I got my money, will not be purchasing car if/when replacement injector arrives.
Is there any chance these injector delays are working out just the way the dealerships are hoping? Any chance the injectors will show up exactly one day after the guys walk away? And I wonder if the cars will be available for sale the following day? With market adjustment prices? Nah, that would never happen.
Sorry to hear the news on the injectors...I just clocked the first 500 miles on my 2022 z51 2LT coupe....and the red line limiter on the tach has jumped from 5000 upto the 6500 mark...and I must say this is my 3rd vette (c6,c7 & now c8) and the car performs flawlessly, and delivers as promised by chevrolet...it is a completely different platform from the c7...and I would have to say the car is worth every penny...and to those who went before us and had problems with the earlier model c8s..I hope they didn't get discouraged and they get all the issues resolved to their satisfaction and they are enjoying their cars...it took a year to get it and was worth it...Kudos the chevrolet for getting this one right

My sales guy/dealership is being useless as expected and wanting to "hold tight" to see if GM sends the part ... we'll see
Did you try calling GM and opening a case? Im going to call tomorrow and see if they may be able to help expedite. In my experience with other manufacturers they don't like open corporate cases and its usually able to light a fire...

Thinking out loud... I wonder if there's an aftermarket supply for an injector? That might be a viable alternative.

Generally speaking, it's a good rule of thumb not to by a first-year run from *any* manufacturer. Statistically speaking, they can't run enough test mules to catch very low-likelihood issues (i.e. if they run 100 test mules and the issue is only likely in 1/2000 cars, they could easily miss it), so you're usually safer waiting 1-1.5 years.

But the data isn't supporting that. Notice that 2014 was the first year of the C7 and it had better reliability than the 2015.
While I agree that some things can pop up that weren't discovered in the test fleet there are also things that can creep into the process.
I used to work in development. When we transitioned to production we initially kept the development people involved since they had the knowledge. It was more expensive initially because of the extra scrutiny involved but that was part of the plan. Eventually they moved on to other development programs. We often had more problems with later components than with the earlier components.
I’ve always rated Consumer Reports as poor reliability, as it does not seem to have experts doing the ratings.
I like Consumer Reports because they are data based and do the testing with product they buy, as opposed to being sponsored or testing samples provided by manufacturers. To each thier own I guess.

Yes, I said *general* rule, not *absolute* rule. Anecdotally, you can always find exceptions. For example, my first-year C8 needed and got a transmission replacement.

The new Annual 2022 Consumer Reports Magazine edition is now out.
My 22 HTC has been at the dealer for going on 6 weeks this Friday with a “Top not secure” error message. The dealership has been in communication with GM and specialists have been there to assist. The have performed adjustments, sensor checks, electric motor replacement, carriage assembly replacement (the first arrived freight damaged), videos sent to big wigs in GM for analysis, and it is still not fixed it. The dealer says GM is planning to do something to ease my pain for the inconvenience, but this is ridiculous. I’ve only had the car 14 weeks and 6 have been in the shop. I managed to get 800 miles on it before I had to take it to dealer. Very saddened to see other C8’s on the road when I’m not in mine to smile and wave!🤪

I don't think they think that far ahead TBH
Probably still makes more sense to make happier customers become repeat customers than orchestrate some conspiracy with GM parts
