2023 Chevrolet Corvette Electrical System Problems

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.

Component/System: Fuel System – Fuel Filler / Left-Side Radiator and Cooling Fan Assembly (subject to NHTSA Recall 25V536). What happened: On June 15, 2024, I was refueling my 2023 Chevrolet Corvette Z06 at a BP gas station in Phillipsburg, New Jersey. As I removed the fuel pump nozzle from the vehicle, a violent explosion occurred. I was immediately engulfed in a fireball. My clothing caught fire and was burning me. I jumped clear of the flames and extinguished the fire on my clothing. I saw that the vehicle remained fully engulfed in flames with the pump nozzle still lodged in the filler. I ran to the adjacent pump island where a station attendant was attempting but was unable to open a locked fire extinguisher cabinet. I broke the glass with both of my bare hands to remove the fire extinguisher. I sustained a severe laceration to my forehead that was approximately 3 inches long and required plastic surgery of over 50 stitches to close. I then ran to the car that was burning with approximately 10 foot flames and I used the fire extinguisher to put out the fire on the vehicle and pump. I then pulled the pump handle from the fuel filler opening and called the police. The police and fire department arrived and confirmed the fire was extinguished. The flames singed the hair on my head and legs. Component availability: Documentation including photographs, police report, and medical records are available. Safety risk: A fuel-fed explosion at an active gasoline pump created an extreme and immediate risk of death or serious injury to me the station attendants and others. Dealer/manufacturer confirmation: GM subsequently issued NHTSA Recall 25V536, acknowledging the defect — fuel spillage during refueling can contact the left-side radiator cooling fan, which remains active even with the ignition off, causing ignition. This recall directly confirms the defect that caused my incident. Insurance inspection: The police and Geico inspected the vehicle. No warnings at all.

This is a 2023 Corvette 70th Anniversary Edition. Button to open door from drivers side doesn’t activate, needing to pull manual handle. Electric button to open hard top convertible doesn’t activate. Vehicle taken to dealer and inspected. According to inspection results, there is major components which controls these functions was ordered and received. Vehicle is at the dealer for repair.

The reverse camera works intermittently, but fails more often than it works properly. Able to reset by shutting car off and leaving door open for 90 seconds, then restarting. Works for that ignition/drive cycle but then becomes unreliable again after next startup. Car is a week old. Have not brought to dealer yet for warranty claim, however as this is a required safety system I am reporting it.

The vehicle has had rear and front camera failure within 72 hours of me buying it (91 miles); and I let my sales guy know, we decided to bring it by the dealership one day when it is malfunctioning. I got it to act up that Saturday 3/18/23 with 123 miles, and it showed 2 DTC's (B1A62 and U0131), but with a limited staff, they had no one to look at it. Still not upset, I said whatever and figured I would just drive it and bring it back during the weekdays It happened again this morning on the way to work, and I took it right in; they were able to scan it again and show the fault codes. This is where it gets really upsetting; the tool/adapter they need to test the AV cable is showing June 16th ship date. I sell cars for a living also, and this is something I would never expect a customer to just deal with and wait. I literally can't drive the car in and out of my driveway without the camera system. My wife almost ran into the door because the camera does not work. My fear is a child could be hit or run over, and I can't believe General Motors is ok with a new vehicle being sold, failing immediately after delivery, and having no way to fix the problem. I have contacted someone at GM corporate, and they also instructed me to wait for diagnostic. This is a concern on other Corvettes, and not the first instance of this happening.
