2023 Chevrolet Corvette problems

POWER TRAIN

While driving normally, I was in the middle of a busy highway/intersection when the vehicle suddenly lost power and came to a complete stop. The vehicle shut itself off without warning, leaving the Corvette disabled in the roadway and causing a complete blockage of the road/intersection. Traffic was actively traveling around me, creating a serious safety hazard and putting both myself and other motorists at risk of a collision. After the vehicle stopped, it would not restart. The instrument cluster displayed a theft-deterrent/immobilizer warning and a lock/security symbol, along with a message stating that there could be a problem with the theft-deterrent system and referring to Immobilizer Operation. The vehicle has full electrical power, but when attempting to start it, it only clicks and the engine does not crank or start. I placed the key fob in the designated backup location as instructed in the owner’s manual, but the vehicle still would not start. The exact failed component has not yet been diagnosed or confirmed. The vehicle is available for inspection. The sudden and unexpected loss of power while I was in the middle of a busy highway/intersection caused an immediate and serious safety concern because the vehicle became completely disabled and blocked the roadway.

WHEELS

At 23000 miles the right rear wheel cracked. I have a 2023 Corvette stingray HTC with the 20" wheels. The option code for this original GM wheel is Q8Q, "20" rear carbon flash painted aluminum wheels with machined edge". This is a common problem and has been reported by many corvette owners on several corvette forums. I do not track my car and have new tires. GM again ignores this safety item. I had the problem on my C7 and again on my C8. I did complete the GM refund paperwork for my C7 cracked rear rims, however, GM never did any refunds or tried to correct this safety issue.

POWER TRAIN

On 10/13 after refuling my 2023 Chevy Corvette. I was cruising on a freeway when the car started showing signs of staying in 5th gear. The rev limiter was going from 500 to 2500 rpm rhythmically at a cruising speed of 65mph. At this time, I noticed the loss of response from the gas pedal. The car was then placed in manual shifting mode so that i can attempt to regain population control and maintain the flow of traffic as this was a high crash area. Unfortunately, this attempt did not work and the dash cluster illuminated with the following alerts "rear axil system offline" "idle creep disabled," "service transmission" at this time. The gear indicator on the dash that shows the mode and gear, for example: D3 (drive 3rd gear), completely disappeared and the gas pedal completely went unresponsive. At this point i used the momentum of the car in motion to exit off of the freeway into a parking center. The vehicle proceeded to not respond in regards to going into park, reverse, or drive. The only thing that worked was the electronic parking brake. This was a very scary situation that, without my federal law enforcement driving training I may not have coasted safely out of traffic.

SUSPENSION

Shortly after purchasing the vehicle at the local Carson City,NV CHEVROLET dealer on 5/18/2025 my passenger started to hear a muffled “thumping noise” from the right front foot well? I am a disabled veteran USAF pilot with hearing loss and did not immediately hear it. The car had 29,129 miles on it when purchased and was a “certified vehicle” with some remaining original warranty as well as an extended warranty given its great condition(I was told!) After a few hundred miles of driving the sound became much louder and VERY noticeable when even on rough roads I discovered when removing the “frunk” trim to investigate a weak battery up front that an aluminum upper suspension right front shock mount was only being retained by a single bolt of the FOUR designed to secure it! Two had sheared the aluminum mount off and one bolt had broken off and was missing! The car has been in possession of the dealer since I had it towed in 6/27/2025 I have had NO RESPONSE from the dealer as to the cause.other than to indicate that it had been a rental car company acquisition No other external body/suspension/tire/fender damage was visible The dealer has confirmed the failure and has to my knowledge not repaired it although they did indicate that GM engineers were advised?

POWER TRAIN

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.

SEAT BELTS

The passenger seat belt locks and pins the passenger down. It will not release unless it’s released from the release button. If there’s an accident, my passenger would be seriously injured.

UNKNOWN OR OTHER

Normal driving conditions while in Z-mode in moderate traffic, an audible bang was heard, however there was no immediate issue. A few minutes later the Check Engine Light, ABS, Traction Control and other lights appear on dash. Once lights appear, brakes fail and no longer slow the car down, the gas pedal only revved the car and could no longer accelerate. The car was still on and “driving”, I just didn’t have acceleration or brakes. I put my turn signal on and eventually was able to safely pull off the road and stop the vehicle utilizing Neutral and the Emergency Parking Brake. I was in genuine fear of crashing due to not having brakes or acceleration and felt that if the parking brake and/or neutral failed, then I’d have to crash to stop the vehicle. Not having brakes or acceleration put myself, my passenger, and every vehicle around me when it occurred at risk of injury. This has occurred twice in less than 1 year of ownership with this vehicle and I’ve taken it to two dealerships, Mike Reichenbach Chevrolet and Rick Hendrick Chevrolet. When it first occurred in December 2023, I was also in Z-Mode in light traffic, after it occurred, I drove slowly to the dealership with the hazard lights on. The second time I brought it to a dealership was after the first dealership couldn’t find the cause nor replicate the issue. The codes were cleared by the first dealership, but the car was still operating roughly and not as designed. The third time, in July 2024, it was brought to Rick Hendrick Chevrolet where the service invoice says “GOOD POSSIBILITY THE AFTERMARKET GPS UNIT PLUGGED INTO THE DLC PORT IS SHORTING OUT THE VEHICLE COMMUNICATION CIRCUITS AND CAUSING INTERMITTENT ELECTRICAL ISSUES. MAY BE ALSO CAUSING BATTERY DRAIN ISSUE.” The device referred to is called Bouncie, I got it AFTER this first occurred and the service team there is blaming both of these occurrences on the device. No repair was performed as the issue couldn’t be replicated.
