I have a 2020 with about 6500 miles on it. No problems except the dealership service was below par so I am going to another. I realize that I have been lucky with this car and do not plan to give it up. I have thought about getting an Eray but just dont have enough faith/trust in GM
to take another chance.
I'm not sure there is enough vehicles out yet to warrant such a thread. All the issues so far are fluke incidents until proven otherwise via incident reports en masse. And the axle breaking was a result of a big shot of nitrous so I'm not sure that even counts.
I'm finding this very interesting. Getting ready to sign on a new one in the next couple of days.
Every time I ride a bit I get this flare on both headlights. They quickly disappear after leaving the car idle for a bit but it does seem strange. Is this problem with the lens? There are not other problems with headlights e.g I haven't notice any moisture after raining/washing.
Two mechanics told me it's normal but I want to hear your opinion and potential advice. thanks!
It might have been due to wheel hop on launch, but regardless you actually want the axle to snap before the DCT has internal damage.
An axle / half shaft is an easy fix.
i just purchased a new 2024 LT3. I have had it about 3 weeks. Has anyone else had an issue with the top not closing correctly? The smaller back panel will not latch. I get a message that the top is not secure. It is going in on the 24 of this month. Just wondering if anyone else has had an issue.

Is there a thread somewhere that lists all of the software/firmware updates? My C8 was built on 5/14/24 and it doesn't show any software/firmware updates nor has any pending; however, I thought other folks have received updates in the last ~2 weeks or so. Were those just delayed updates? I'm wondering what updates correspond to which features and which build dates/etc. If one doesn't already exist, does anyone know of a website/page that documents them?
Just started getting a "Service Parking Assist - Soon" message. I have an oil change in about 3 weeks at dealership. Was wondering if anyone dealt with this issue.
1. Rear/front cameras are working
2. Beeping sounds work as well
2021 C8 Leather lifting and bubbling on passenger side
[QUOTE=MauiC8;1601129782]Now that C8s are starting to roll out, I thought it might be good to start a single thread of issues people have noticed, however big or small they may be, to raise awareness for what other members should look for and what GM can continue to improve upon. I’m hoping this can be made into a “sticky” to find it easily and requesting everyone to please keep it positive and not bash GM, Chevy, or the dealers and not to compare any issues to other manufacturers as that wouldn’t be helpful to any of us.
Some issues that have been noted so far...
Passenger window started going up and down by itself while driving. Crazy. Any idea what going on . Goes back to service tomorrow. Vehicle is sweet though
Transmission leak?
Weak axle?
Granted it broke drag racing with nitrous, so maybe well deserved, but a warning to those who are considering mods
Seats
Dash
Same issue on several locations on the passenger side dash of my 2021 C8. Being replaced by Chev but only 2 weeks before my factory warranty due to expire.
Also told by the dealership they’ve replaced at least 5 with the same issue this year.
Obviously a systemic problem and note a fluke…
as for the rest of the childish rants in the threads….best of luck!
C8's fans running constantly after new Borla Exhaust
Hey everyone, I just had my borla atak exhaust installed on my C8 stingray and ever since, the fans have been running constantly. Even during nice weather and gentle driving. Any feedback on this?

I have had 3 dashes changed out due to the leather not adhering. Now, just after 37,000 miles, it needs changing out again! I'm sure they will resist due to being out of warranty now. In my opinion Chevrolet, it is a defective product issue not a warranty problem. Hopefully the Dealer will have some advice. One thing is for sure - this will be my last corvette - not worth the hassles dealing with the same issues again and again. BTW, I'm also on my 3rd transmission! Definitely not the experience I expected.

Very sorry to hear this. Nobody likes issues. You, however, are an anomoly.

Wow you have had some issues. I have been fortunate so far with no issues at all. My 3LT dash appears to be holding up great, knock on wood. I check it every time I get in the car. Transmission seems to be fine at 11,000 miles. A friend of mine had a cable snap on his HTC and he couldn’t raise it up. It was fixed under warranty and I believe he said the cable was actually a Ferrari part. I thought that was strange. I wonder if GM licenses the HTC option from Ferrari. Sam

Does the car sit outside a lot? Do you live in an extremely hot region? I like many others are curious why some cars have this issue and others don’t. You would think that with 3 replacement dashes the odds are that you would get a good one. Sorry to hear this. I don’t blame you for never buying another Corvette again. Sam

Second Transmission Replacement Needed: 2022 Stingray with 31,000 miles.
First transmission was replaced in May 2022 at 3,500 miles due to a porous case; now at 31,500 miles GM has deemed I need another new transmission due to extreme gear noise.
The replacement transmission was always "noisier" than the original and I was told to see if the noise diminished as it was broken in. At the 7,500 mile mark I formally complained with the dealer and after some back and forth with GM the noise was classified as "normal" and I was told to monitor it and advise if it got worse. And over the past 28,000 miles it got noticeably worse until it sounded like a screaming banshee under certain driving conditions! Had this been a normally configured car, I would have diagnosed a failed pinion bearing as being the noise source. The dealer did the FICO procedure - that file is in MP4 format and the forum does not permit that format to be uploaded otherwise I would post it - and finally sent it to GM for review.
I honestly expected a battle with GM but they came back within an hour to say "new transmission needed". So now I am waiting to hear when a replacement trans will be available - a couple of days to a few months is the dealers guess at this point and no guarantee that it will be the latest design. At least the vehicle is still usable so the wait will be tolerable; I'm just glad all this occurred before my soon-to-be-required 3-year DCT fluid change was needed!

I wonder if these replacement trannies are new or remanufactured. And if they are remanufactured, who does the remanufacturing, GM or Tremec? What a fiasco!
