Chevrolet Corvette transmission failure problems

Filed Oct 22, 2026 · Electrical, Fuel system · TX · crash

While operating my 2023 Chevrolet Corvette at approximately 75 mph on [XXX], the vehicle suddenly and unexpectedly lost propulsion. Moments later, the vehicle completely shut down. The instrument display went dark and the vehicle's lights went out. This occurred in active highway traffic. I struggled to maintain control of the vehicle while avoiding surrounding vehicles and narrowly avoided a potentially catastrophic collision. I managed to bring the Corvette to rest on the shoulder. The vehicle was subsequently transported approximately 20 miles to an authorized Chevrolet dealership at my expense. The dealership retained the vehicle for approximately five months. During that period, I was not provided a courtesy or replacement vehicle. The dealership replaced the transmission under the manufacturer's warranty. The replacement transmission part number may differ from the original, but this requires confirmation from repair records. Although the transmission was replaced, I do not know whether the dealership separately diagnosed and corrected the cause of the complete electrical blackout. I am concerned that the loss of propulsion followed by a complete electrical blackout represents a serious safety defect that could result in a collision, serious injury, or death. I request that the federal safety agency investigate the failure, including the relationship between the transmission malfunction, loss of propulsion, and electrical shutdown.

On 8/3/2025 I was at a stop light. It turned green. I went to go and my car would not go past first gear. Had to pull over. Waited turned the car off. Turned it back on and started driving, then I got an alert 545. Then my entire screen went blank only showing the alert. I called my dealership to explain. They said there were recalls on the 2023 and 2024 transmissions. That’s why I got the alert 545. But they said there was nothing they could do. I could bring it in for a test drive with a technician and if it pops up alert 545 then they would submit a ticket to GM. But the earliest to fix my corvette would be October. But also saying I would have to pay full price for everything. I bought my 2023 Corvette 1LT C8 stingray in 2022 and have only put 19,000 miles on it. I do not miss maintenance or anything. I’m not sure how to get GM to pay for my transmission and labor. It also would not let me acknowledge and click the button on the steering wheel. My display went off and I could not get it back on even turning the knob. This is incredibly dangerous for my safety. Transmission failure. Can’t see the speed I’m going.

I had a complete transmission failure while on a road trip over July 4th. I just read that GM was doing a recall on the Transmission Control Module but it does not include my car, which is what failed on my car at 19,000 miles. My trip was interrupted, we spent two days paying for hotel & rental car in Springfield, MO and now my car is fixed with new TCU in Springfield, but I live in DFW area. If my car had a recall I would have had it fixed before our trip and this all could have been avoided. Now I have to figure out how to get my car back home.

Transmission shuttering/noticeable vibration while cruising. Dealer replace transmission fluid and shuttering resolved. However, upon initial 1st and 2nd gear engagement on the first drive of the day, the transmission hesitates and aggressively lunges forward at a higher speed than anticipated. Not safe, normal or desirable. This is a known problem that the dealer knows about but what is the resolution/fix to the issue? No warning lights have been displayed.

Since the vehicle was new, it has exhibited a transmission shake or shudder that is especially noticeable when the Active Fuel Management is active. The vehicle was serviced by Chevrolet under warranty on Dec. 5, 2017, for a transmission shake and/or shudder repair using the flush methods described in Bulletin No. 18-NA-355, but it has continued to exhibit a transmission shake or shudder. My local Chevrolet dealership has now diagnosed the vehicle as having a torque converter with excessive slippage and recommended a replacement torque converter at a cost of $3,450 including parts and labor, or a total transmission replacement at a cost of $8,100. My vehicle currently has 24,473 miles on the odometer. A major transmission component should not fail in less than 25,000 miles on a modern flagship vehicle used for light, non-everyday driving from a leading U.S. auto manufacturer.

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.
