I experienced a known issue with my transmission with the MIL code P2812. The TSB PIP5799 which has to do with the Electrical fault in Transmission Control Solenoid Valve 7 (Line Pressure Solenoid). I took it to the dealership and left it there for a week only for them to be unable to figure out the root cause and fix it. So I had to pay a $180 diagnostic fee, only for the same exact problem to occur not even a week later.

The contact owns a 2021 Chevrolet Camaro. The contact stated that while driving at an undisclosed speed, the wheels locked up and the vehicle stopped abruptly. There was no warning light illuminated. The vehicle lost electric power and shut off. The vehicle was restarted. The contact attributed the failure to the internal transmission control valve (TCV). The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 25V148000 (Power Train). The vehicle stalled on several occasions while driving. The contact initially dismissed the intermittent stalling because the vehicle temporarily returned to normal operation. The contact stated that the check engine light occasionally illuminated, and the vehicle was taken to an independent mechanic where it was diagnosed with transmission control module failure. The vehicle restarted independently, and the code was erased. The manufacturer was notified of the failure. The vehicle was not repaired. The contact was informed that the transmission needed to be replaced.

On XXX my 2021 Camaro developed excessive transmission whine and intermittent harsh shifts. Capital Buick GMC ([XXX]) diagnosed “worn internal fluid pump” and quoted $8,263.46 for complete transmission replacement. This vehicle is subject to NHTSA Recall 25V148 (GM N242480630) for 2020-2022 Camaro 10-speed transmissions where the control valve “may be susceptible to excess wear… causing harsh shifting” and potential wheel lock-up. GM TSB 22-NA-232 also specifically lists pump noise as a known diagnostic condition for this transmission. Despite the recall, the dealer attributes my failure to internal pump wear and GM has denied warranty coverage, offering only 25% goodwill. This is the 5th major powertrain failure on this vehicle in 32k miles (engine replaced at 45,172 mi, cylinder head replaced after 36 days out of service in 2025). I am reporting because a worn pump causing pressure loss is the exact failure mode described in the recall, and presents a safety risk of sudden loss of propulsion.

I own a 2021 Chevrolet Camaro SS equipped with an automatic transmission. Before the recall for “Momentary Wheel Lock-Up” was performed, my vehicle began experiencing harsh shifting, harsh engagement into Drive and Reverse, and the transmission would occasionally lock up while backing up, making it feel like the brakes were suddenly applied. On one occasion, the vehicle also attempted to move forward while still in Park. I brought the vehicle to a Chevrolet dealership because these symptoms were similar to the recall description. The dealership completed the recall software update, but the symptoms did not improve. The dealer later diagnosed the vehicle as needing a complete transmission replacement due to internal transmission damage and stated that the failure was not related to the recall. The dealership recommended replacing the transmission at my expense. My concern is that the safety-related symptoms existed before the recall repair, continued after the recall was completed, and still create a potential safety hazard. The vehicle can unexpectedly engage harshly, lock up in reverse, and behave unpredictably during low-speed maneuvering. I am submitting this complaint because I believe the recall remedy did not resolve the safety concern, and I would like NHTSA to review whether the recall adequately addresses this condition
