While disappointing, this is why the PDI process exists.

 

What a nightmare

 

C7's had this too - it's an issue with the electronic control for the rear axle, I think it means no posi rear or locking action in the diff.
The fix for the C7 was a reprogram or reset.

 

right OFF the Bat am not a 50 year Corvette expert nor do i have the money to **** away reading these nightmarish posts is concerning 80 K for the car and Trans is leaking , or Odd and Even Gear issues been wanting a vet since i was a kid , time is now am not getting younger than what i am 58 emmmmmmm am on a list for the 2021 Convertable hate leaks Trans or Water get my drift any word of wise from older Corvette owner to calm my nerves lol

 

You have a warranty... Chevy has a large dealer network... problems are over blown in the forums.

 

am getting the extended warranty as well , Thanx for the reply , i get u are a previous or current owner , soon am going to configure this car at the dealer as the lingo goes am not going to Track this car so somwhere i read better getting a 2LT than 3LT and just add some of the options urself any thoughts on it?

 

This was not my car, but my buddy's car. we picked up 3 C8's at the museum and drove them back together. This problem did not show up until after we got back.
Dealer was not sure what the issue was so they contacted GM, The engineers wanted to know of he had been tracking it, doing donuts or launch control, none of which he has done.
GM told the dealer to add 2 quarts of trans fluid to the DCT which they did and gave back to him today. In my option this is just a band-aid and if it cures the problem, then why don't they put those 2 extra quarts in at the factory.

Time will tell.

 

Trans overfill is for track use to keep the sump submerged in high G events. It wasn't added from the factory in all cars because it reduces economy and most will never need it. Yes, it's annoying, but there is logic behind it.

 

Update: Surprise, Surprise.. The problem came back within 24 hours and the C8 is back in the shop. The dealership is doing all they can and getting GM involved to figure out what the problem is. I can guarantee you that this C8 was broken in correctly and never even driven hard.
Will post more updates as they become available..

 

I bought my 2001 after the C5s had been out for 5 years, yet it had many issues over the 13 years that I had owned it. You would think that GM would learn its "quality" lesson but it seems that they never do. As long as customers ignore the issues and keep buying, there is not much incentive for GM to focus more on this aspect.
The first surprise to me happened when I received delivery of the car. It had 3 miles on it and still had the protective sheets on various components. As I was washing the car, I noticed that the "Sail", which is the wrap around piece, the rear part of which supports the rear of the targa top, was shifted towards the passenger side so that I could see that it was not centered as it glued in place. I took it to the dealership autobody shop and was told that there was nothing they could do.

 

You had it for 13 years! Why would you even care about a C8 after all those problems?

 

Before that I had a 68 Vert for almost 22 years. I guess I'm a sucker for punishment! I have to admit that I enjoyed the experience, overall, but coming from a manufacturing engineering background, I know that what you don't fix at the root level will come back to haunt you. In some cases, quality people have their hands tied because getting things out the door overpowers the quality aspect. (Tesla, this applies especially to you.)
My 2001 example: Every 2 years, the rear smog pump check valve, which was in between the engine and firewall (requiring the intake manifold to be removed in order for the valve to be replaced) failed. This had been happening to C5 Corvettes for more than 4 years, yet it seems that the replacement valve was exactly like the failed valve. I guess no one at GM was told, "Look, you own this problem, so fix it." So the failures continued for many years without resolution. (every 5000 miles in my case)

My 68's brake light switch would fail every 4 years but when I had enough I thought for sure that the 2001 would be more reliable. Nope. But hopes springs eternal and here I am, rooting for the 2020 to be bulletproof. Sadly, it doesn't surprise me that it isn't.

 

See my posting, above. Good luck.

 

It's the luck of the draw. You can get a Monday assembled Corvette or one that was assembled on a late Friday afternoon. Based on your story I'd consider you VERY LUCKY! My C5 ran great. Only problem were the leaky seals around the windows. That was fixed in the C6 with the window cycling. HOWEVER the C6 was the most unreliable car I've ever owned. You never knew when it was going to run. The CAG on the manual was awful. Even worse was that you never knew if you'd be able to get it out of reverse w/o having to get out of the car and rock it back and forth. The list goes on. I swore off Corvettes after the C6 however now I'm back for more GM punishment. I guess I'm a masochist as heart.

At GM quality ALWAYS has and ALWAYS will take a backseat to production numbers. It's the GM way.

 

I get a few of your points but I disagree and know GM is not the same company by 75% since their bankruptcy. Mary B is an engineer and that is a good thing like her or not since she is running GM. It takes a long time to turn around a company, look at what Kia & Hyundai have done back in the late 90’s they were a complete joke. Today they are pumping out products that exceed Honda and many of their competitors. GM still needs to weed out that 25% but they are making the best most reliable products since they started as manufacture. I had an L82 1980 corvette in 88 and had nightmares for decades saying I would never own another POS Corvette again. I purchased a 2003 C5 Z06 and it was reliable only with a few issues, but the interior was Fisher-Price plastic garbage. I have owned over 60 cars/trucks and most of my vehicles have been European vehicles and I am extremely OCD. My C7 Z51 & Z06 both we’re well-built cars with no issues during ownership, still felt the interior quality was lacking compared to its European competition. When my C8 was built in June the line was going at a much slower pace then they are building today. Car companies get in a little trouble no different than any manufacturer when they try to meet demand and start pushing out their products at a higher rate than the employees and the process can keep up. I know Ferrari, Lamborghini, Audi, McLaren are mostly hand-built cars and their lines are much slower. Anyone who ever has held a job realizes what it’s like to be pushed to a point of quality of work that could suffer. The C8 is a completely new car, very different than the FE’s it’s replacing. When my C8 arrived at the end of June my C8 fit and finish are on par with many of the Porsche’s, Audi’s and BMW’s I have owned.

If I was skeptical and had reservations like some of your post point in that direction, I would buy a preowned C8 that is all sorted out and make sure the owner has had no issues. Most of the time if there is going to be a mechanical issue it’s going to show itself in the first 6 months of ownership if driven on a regular basis. Whoever gets my C8 when I decide to sell her will be getting at least in fit & finish a truly well-built car, she been perfect so far. I was driving a Lamborghini EVO two weeks ago and I was surprised at some of the fit and finish issues I found on the car, not horrible but at 250k + no thanks but then again I am extremely picky. The C8 is a game-changer for GM and an incredible machine that still needs a little more to push it further. I wish GM went Mid-Engine with the C7, I could only imagine what the C8 could have been by now if they did. I can’t wait for my C8 Z06 to arrive until then I will enjoy my C8 Z51 until I move to my next toy.

 

You really don't get it, these cars are on the line for four days before they are complete. Mine is a Thursday, Friday, Monday, and Tuesday car. That being the case, every single Corvette made is at the very least on a Friday or a Monday.

 

I hear what you're saying, but the "New" GM has had 11 years now to get their act together and as best I can tell by their last response to the "flying frunk" problem being a user issue all I'm seeing is the same Old GM. The same old GM is a GM where a problem isn't fixed until the problem becomes more expensive than the fix.

The other problem with the "New" GM is that it desperately needs to change the way it allows its franchised dealerships to go completely rogue and continue to prey upon customers. As the owner of the franchise GM can exercise great control on it's franchisees IF IT WANTS TO. In order to exercise real change you have to show that you actually want to change. I see no evidence that GM wants to change. If GM did exercise their control over their franchisees you wouldn't see rampant "bait and switch" tactics such as introducing a $10k premium at delivery on a C8 order that a customer waited on for a year or longer. You wouldn't see dealers charging $40k over MSRP. GM simply needs to take out the "S" of MSRP. If this type of positive change were to occur you wouldn't see hundreds of people flocking to a handful of dealers for their C8 orders.

Real positive change can be shown in a lot of ways. One way to gauge real change is how well a company is doing in terms of its long term stock performance. Look at these charts which shows that GM hasn't been able to increase and maintain its stock price above the IPO price of the New GM back in 2010. The fact that GM can't keep up with the major stock indices tells me a lot. As far as Mary B is concerned I would think she'd have a lot of more important things to do than fight a grudge match with Fiat Chrysler. As a Corvette fan I think the best thing that could happen would be for Corvette to spin off from GM.

The 01's smog pump check valve was only a small part of the issues.
Diff seal leakage (2X)
Ground connection issue
EBCM failure, almost resulting in a crash
Column lock failure
Other leaky gaskets
Wind motor making noises
HUD fading when ambient temps rose above 75F
HVAC display died
I sold the car when it had 52,000 miles on it.
You get the picture. The really sad thing is that in the early 70s, an uncle told me he would always wait a few years after an American car model change to allow the manufacture to "get the bugs out". Obviously, even today this is true, not only of American vehicles but also of German vehicles.

 

How long did you have it before this paint problem showed up?
I have the same problem as you. It seems the tolerances between the headlight and the fender/bumper is too tight. Did GM offer to fix this?

Sadly, my hood just flew open as well (non-user error) so it looks like I might have to repaint the whole front of the car. My c8 has about 1300 miles on it right now. I heard from the dealer that my car in particular was delayed at quality control for an extra 2 weeks as well.

 

Did you miss all the talk about the hoods flying open?

The paint is terrible for a brand new car. Get GM to replace it all. It is under warranty so make them take care of it and don't take no for an answer.
