2023 Chevrolet Bolt Euv

The contact owns a 2023 Chevrolet Bolt EUV. The contact stated that while the vehicle was parked, the message "Service Transmission - Unauthorized Shift" was displayed. While attempting to shift into drive(D), the gear shifter failed to move to the intended selection. The contact stated that a tow truck arrived and while loading the vehicle onto the flatbed, the driver attempted to shift into neutral (N), but the transmission failed to respond. The vehicle was towed to a dealer; however, the failure could not be replicated. The manufacturer was notified of the failure. The failure mileage was approximately 28,000.

The radio amplifier is mounted in the rear trunk wheel well attached to the bottom, along with the subwoofer assembly. Under the amplifier is a small drain. My trunk leaked during the rain and shorted out the amplifier. This shut off all communication noise in car. No noise from blinkers or warnings of dangerous situations. According to AI, "The 2023 Chevy Bolt EV shares the same basic body structure and rear hatch design as earlier models (2017–2020), and there is no confirmed evidence that the trunk seal was redesigned or improved to prevent water intrusion. Despite a known issue with water leaks into the trunk—often due to voids in seam sealer or compromised tailgate gaskets—General Motors issued a service bulletin (18-NA-182) that applied only to 2017–2020 models. However, owners of 2022 and 2023 models have reported identical leaks, with water pooling in the rear cargo area and damaging components like the amplifier located in the spare tire well." Remember, when the amplifier goes out, every warning signal goes out, as well as radio and hand free operation of cell phones.

What component or system failed or malfunctioned, and is it available for inspection upon request? The door locks automatically unlock when the car shuts itself off if the key fob is inside. Yes, it is available for inspection. How was your safety or the safety of others put at risk? Twice now, once in this car, and once in my previous car (a Bolt rather than an EUV) I fell asleep at a charging station, in the Texas summer, with the A/C running, and when I woke up, the car was off and the doors had automatically unlocked. I believe this has happened to other people. See, for example: https://westchester.news12.com/police-duo-to-be-charged-after-stealing-a-car-while-it-was-charging Has the problem been reproduced or confirmed by a dealer or independent service center? No, but as I wrote, it has happened to me with two separate vehicles, a 2019 Bolt, and a 2023 Bolt EUV, and it is eminently reproducible. Get in the car, lock the doors, leave the car on and wait an hour. When the car shuts itself off, it will unlock the doors (I believe because the key fob is inside.) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. But I sent an unacknowledged email to GM's general counsel on 9/1/2019 the first time it happened in my 2019 Bolt EV. It still happens in my Bolt EUV. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

Water intrusion occurred inside the rear taillight assembly, resulting in visible moisture/condensation within the housing and subsequent taillight malfunction/failure. The affected taillight performs critical rear lighting functions, including brake and signaling illumination. The presence of water inside the sealed taillight assembly indicates a failure of the lens or housing seal. Over time, moisture intrusion caused degradation and failure of the lighting function. Loss or impairment of rear lighting reduces the vehicle’s visibility to other drivers, particularly at night or during adverse weather conditions, creating a safety risk related to rear-end collisions and improper signaling. The condition developed during normal vehicle use and exposure to rain and environmental moisture. No collision, impact, or external damage occurred prior to the failure. No dashboard warning messages or alerts were observed prior to discovering the issue. The vehicle was inspected by an authorized dealership, which confirmed the taillight failure. The dealership stated the light source is not serviceable and that the entire taillight assembly must be replaced. The manufacturer acknowledged the issue but stated the vehicle was outside the warranty period and offered only a partial goodwill assistance of approximately 20%, leaving an out-of-pocket repair cost exceeding $800. Multiple consumer reports and online owner discussions document similar instances of water intrusion and taillight failure on Chevrolet Bolt vehicles, suggesting a potential pattern related to taillight design or sealing rather than isolated damage or maintenance-related failure. The affected taillight assembly remains available for inspection upon request.

Forward collision prevention system activated unnecessarily. I was already breaking and on track to stop well behind the vehicle in front of me. I had just pulled around stopped traffic in another lane, which seems to be common in all the incidents I've had like this. The safety concern is that the vehicle stopped unexpectedly, and if traffic behind me hadn't been paying attention, they could have run into me. In the past I asked a dealer to look into it, and found nothing wrong. Deactivating the system for a time, and then reactivating it, seems to improve the problem for a while.

The camera system—including the backup cameras when you put it in reverse— more often than not produce an error on the display screen instead of a view of the rear rendering this mandated safety device unusable. It is available for inspection. The rear view camera is a mandated safety device required on all passenger vehicles. Not having it available makes it much easier to back into other vehicles or pedestrians walking behind the vehicle. This is a reproducible issue. It was inspected by a dealer and a problem was confirmed. It was repaired with a new module under warranty. Three months after the repair, the issue has reoccurred and the vehicle is no longer under warranty. The repair from the dealer did not fix the issue. It has not been inspected by anyone other than the dealer. There is no warning prior to the issue occurring. The only warning is a crossed out camera as the error occurs. An internet search shows this is a very common issue with this vehicle.
