EXTERIOR LIGHTING, VISIBILITY/WIPER
"Both front headlamp assemblies have internal moisture condensation and permanent residue/streaking on the interior lens surfaces. This is a known manufacturing defect documented across 2020-2024 C8 Corvette model years. GM issued TSB 01-08-42-001P acknowledging this defect. Cox Chevrolet documented both headlamps as 'DEFECTIVE HEADLAMP LENSES' on repair order #428778. The vehicle has only 3,700 miles. GM's own Policy Evaluation Tool confirms zero miles driven out of warranty. GM offered only $250 in rewards points in response to a formal Magnuson-Moss Warranty Act demand for $5,050 in repair coverage. GM Case numbers: 91145522 and 105260981. This is a safety concern as defective headlamps reduce nighttime visibility."

UNKNOWN OR OTHER
The vehicle has the dash lifting started to happen a month after I bought the vehicle that a bubble formed and now it’s peeling off it’s a common issue on all Corvette 3Lt’s and Chevy is aware of it and charge customers $3,000 to replace it and don’t think it’s right to do that and should own up to mistake but forums of Corvette owners show how common of a issue it is on the 3Lt trim since it’s leather.

POWER TRAIN
Noise from the rear of the vehicle. Took vehicle in to dealership. The determined that it was a left side loose axle nut. This is clearly a safety issue. It may not have been torqued properly at the factory. The vehicle is a 2021 with only 5500 miles. They did the repair/tightened the axle nut and the noise is gone.

ELECTRICAL SYSTEM
I cannot believe the Corvette does not show that the alternator does not show that the car is not charging. I have a thirty year old corvette that will show you when the alternator does not show the car has an under performing alternator. If you do not have it showing on the display it will not show you that the alternator is defective. You have to show it on the display you never know you have a problem. It is an issue that is not a problem unless you know. I bought a battery and it was the alternator. They need to do a software upgrade to show you when a system goes out. My 1992 Corvette show you when there is a problem. Pathtic support on the part of General Motors.

POWER TRAIN
At under 3000 miles car started sputtering sporadically and stopped driving while in motion. We were able to get the car home. Tried to start the car back up and it violently surged. Car had no idea what gear it was in. Transmission service now light came on and car sent me an email stating to take it to the dealership. Had car towed to dealer and used tow company they requested me to use.. Dealer says valve body flooded and replaced it. Still not working correctly and dealer says transmission is being flooded. Gm engineers not sure why. Car has been at dealer over a month and have no clue when it can be fixed. When you shifted from park to reverse car would lunge violently like you threw the transmission into park while the car was moving down the street. Car is not safe to drive as it just started to have issues during regular use. Dealer has confirmed and recreated the problem. I was told if valve body didn’t fix it that gm would overnight a new transmission. Now I’m being told they want to continue to debug the issue and they have no clue on what the issue is or when it can be fixed. I’m out a vehicle I count on and am still paying for a car that I can’t have use of. Dealer is dodging my calls now. Here is my open case with Chevrolet asking about lemon law protections since it may be another month before I get my car back. [SR:9-7132169239 Car has under 3200 miles on it and is their flagship product.

POWER TRAIN
At approximately 700 miles, my check engine light came on and the car produced an error message that said "Idle Creep Temporarily Disabled". Soon after that the car would lurch, buck on acceleration, and would only drive in even numbered gears. I felt the car was extremely dangerous and unpredictable to drive in this state since the car was unpredictably bucking and lurching forward and not shifting smoothly as usual. The dealer ran an OBDII poll and found five codes relating to transmission issues. GM has admitted to me that my vehicle is one of several that have "Assembly Debris" in the TREMEC supplied DCT. This "Assembly Debris" made the transmission filter completely black in appearance at 750 miles in addition to triggering the check engine light and dangerous driving behavior.
