Got in some heavy stop and go traffic yesterday and the car just didn't drive/shift very smoothly, maybe because the car always tries to shift through 1-3 so quickly.
Is this normal or may I possibly be looking at the start of transmission problems? I have just under 1000 miles on the car. Thanks.
Bring it into your local dealership and have a Corvette specialist / technician take it for a drive. Posting on message boards is an exercise in frustration. I was experiencing harsh downshifts from 4th to 3rd and lunging/lurching forward when coming to a stop and going from 2nd to 1st. gear. So many people told me that this is normal and how the DCT is supposed to act. I finally brought mine into the dealership and received a phone call from the Corvette tech stating that the car demonstrated highly unusual shifts and this was not how this vehicle was designed to perform. After a day of evaluation of the vehicle, GM authorized a replacement of the transmission under warranty. I can't wait to get mine back and be able to truly love the vehicle I have desired to own for so long.
Brand new to corvettes and at 111 miles on my 2026 c8 my engine light came on.
I was going about 30 mph and accelerated to merge and the car seemed to shift really hard and then my light popped on.
I’m taking my car to a dealer Monday but anyone have any ideas?
I’ve been easy on it while driving while the engine breaks in but this really took the proverbial wind out of my sails.
Hard shift and CEL, hopefully they can replace DCT filter and run some cleaning procedures, but likely a valve body issue with some debris stuck in a solenoid.
Sometimes they can swap the valve body out a lot faster than having to replace the entire DCT.
2LT and 3LTs are supposed to have motorized folding mirrors. Only the 1LTs don't have motorized mirrors. The button is on the drivers side door armrest below the mirror adjustment buttons. They can be manually moved in an emergency but I don't know what regularly manually moving them does.
I have them setup to fold automatically when I park, like at work or when I go somewhere and park in the street or a public parking. I also fold them manually when I get home because I need to go through a narrow gate. When you fold them manually, you can unfold them manually as well or wait until you go 12mph an they unfold automatically. When I let them fold automatically (which they do when I cut off the ignition), they unfold when I start the engine. I find this quite convenient.

When I said fold them manually I meant physically moving them from the outside, not using the button. I don't know what physically moving them from the outside like you can do with a 1LT does to the internal mechanism on a 2LT/3LT.
2022, 2LT. 15k miles. High pitched rhythmic squeak or chirp. Doesn’t sound metallic per say. Engine runs great. Sound is in all modes idle or at rev. Car has oil. Oil at 48 % to next change.
any ideas what this sound is, and cost to fix whatever that suggestion is.
It stopped reading the left front tire after reporting it at 0 lbs. I thought I had a flat before pulling over to check the pressure. I then got this warning message. This is my 3rd warranty service in 18 months of service and only 10,000 miles. This time the sensor was in stock and it took about 2 1/2 hours as I waited. I must have used up my free loner I got the last 2 times as they said "we don't offer loners for maintenance work".
Hoping the next 18 months go better and shopping for an extended
warranty to replace the bumper to bumper. Any thoughts on that?
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
I just purchased a 2022 Stingray Z51 3LT Coupe in September and have already gone through 2 batteries. My observations are:
-Parasitic draw and GM can't figure it out
- When the sun hits the rear window it is blinding and impossible to see out the back
- Seat setting doesn't always go to correct position when starting the car
- When filling up the tank there is a large disparity on miles to empty, anywhere from 260 - 330 miles to empty. People trying to explain the rationale behind it are totally wrong.
- People say you must charge the car overnight are totally wrong. This isn't a special car
- Cheap interior
when I think of more I'll post them.
Yeah you're right! Why should I care that when I fill up once it'll say 330 miles until empty and then the next time it might say 260 miles! Why should anyone worry that there is a 70 mile difference between fill ups. I drive the exact same way so this is an issue with the algorithm or something but I don't think it's working like GM thought because either the car is controlling my fuel mileage to 70 miles less or the gauge is wrong! Which is it! I have NEVER owned a car that has ever done this. GM needs to get ahold of the Euros and ask for help. ⁰
Either an operator problem filling up the car or something wrong with the fuel sensor. I've been able to get those kind of differences in mileage until empty, but only when I've driven in drastically different mileage situations (like long highway trip for one tank and stop & go driving for the other) before the next fill-up.
Back in mid October, my brother-in-law took Museum delivery of the '26 3LT Stingray coupe that he ordered. Now at less than 800 miles, his DCT is leaking. He dropped it off last Saturday, but on Tuesday they said they wouldn't be able to get around to it until Friday. Poor guy...his first Corvette. He had stars in his eyes while he was waiting for it to come...and now, this.

How can folks deny that the DCT is a problematic transmission? Wait till owners out of warranty have problems.
I believe this was Tremec's first stab at an "automatic" (yes, I know). They're manual transmission people...and perhaps should have stuck to what they do best...
Update:
The diagnosis is in. Its a leaking axle seal...and here's a shocker: the seal is on back-order. Now we just have to hope that 1) the leaking seal is just due to a bad seal, and not to an incorrect finish on the axle's sealing surface, and 2) the new seal comes in sooner, rather than later.

Designer Imagines A Corvette That Looks More Like a Corvette Than the Corvette
Slideshow: A Jaguar designer's personal project imagines what a modern front-engined Corvette might look like if Chevrolet revisited the golden age of the Stingray.
