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 the federal safety agency 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 the federal safety agency to review whether the recall adequately addresses this condition

Vehicle is doing a hard shift from first to second, severe shuddering, sometimes when braking vehicle acts like it wants to surge forward took to a transmission shop I have a bad torque converter and was told this is a problem with the 8 speed transmission from GM. This is a known issue with these transmissions that GM /dealership knew and refuse to fix. The vehicle stalled on me on a road at night where there's no stores, I'm a female alone on a dark road for about 30 minutes trying to get car to start. Luckily it did. This could've caused an accident and my safety was at risk being stranded alone at night. I was told to not drive the car until fixed. I do not have the funds to fix this issue and GM does not respond to requests, Chevrolet is not helping either.

Transmission Failures.The issue initially presented as intermittent trasmision shuddering, hesitation during accelaration, harsh and delayed shifting, and noticeable vibration, particularly at low speeds and during gear changes. These symptms progressively worsened over time and affected drivability and safty. Prior the failure, there were no warning lights or dashboard messages displayed. Based on professional diagnosis, they are consistent with internal transmission defects commonly reported for this model.(GM's-8 speed automatic transmition 8L45/8L90)Technical Service Bulletins TSB18-NA-335 and TSB16-NA-175.

* Initial Transmission Failure: -In February 2025 my vehicle began experiencing severe and rough shifting, which was quickly followed by a "Check Engine" light. I immediately took the vehicle to dealer for inspection. * Dealer Diagnosis and Repair: -The dealership diagnosed the issue as a worn-out transmission solenoid and valve body. They informed me that they had to install a newly redesigned valve body and replace the solenoid. The repair was completed at my expense, and I paid approximately [$3000]. The dealership had my car for over six weeks, during which I was not provided a courtesy vehicle. As a result, I incurred thousands of dollars in rental car fees. * Denied Reimbursement Claim: -The recall notice included information about reimbursement for out-of-pocket expenses. I was told by the dealership's service advisor that I would receive a reimbursement form, which I did. I meticulously filled out the form and submitted it with all the required documentation, including my repair invoice and proof of payment. The dealership rejected my claim, stating that my specific repair was not covered by the recall and that the recall was only for a software update. This is demonstrably false, as the recall notice itself links the software issue to premature component wear, exactly what I experienced. * Ongoing Safety Concerns: -To make matters worse, I am now experiencing new transmission issues, including slipping, just months after the "repair." I am terrified to take the vehicle back to the dealership, knowing I may have to pay thousands more for rental cars and another repair that may not even solve the problem. I am concerned for my safety and the safety of others on the road, as a failing transmission can pose a serious hazard. I am requesting that the federal safety agency investigate this matter. It appears that GM and its dealerships are misleading consumers and failing to honor their responsibility to reimburse owners for expenses directly caused by a known defect.

The camber plate nut fell off inside the shock causing me to lose control and go through a field. The camber plate is the only thing holding the strut to the vehicle and should have had a locknut from the factory as it's nothing more than a ball joint. It is available to inspect. It caused me to lose all control when it separated. I own a garage and confirmed failure myself. No i called Chevy about it and even asked if they wanted to send a factory rep out to look at it. I was told no and the only way they might be able to do anything is if i take it to the dealer for repairs. It was giving a small clunk at times that i thought was normal characteristics of the aggressive suspension. I do have pictures showing the failure as well if you would like them.

The component that failed is the 8-speed automatic transmission and torque converter on my 2016 Chevrolet Camaro SS. The system experienced shuddering, slipping, and overheating, leading to unsafe driving conditions. The defective parts are no longer available for inspection because they are being replaced through a dealership service center, but the vehicle and records of prior repairs are available upon request. My safety and the safety of others were put at risk because the transmission caused hesitation, loss of power during acceleration, and unpredictable shifting. This created dangerous situations in traffic where the car failed to respond as expected. The problem has been confirmed and reproduced by authorized GM dealers during multiple visits. They have identified overheating and failure codes related to the transmission and torque converter. The vehicle has been inspected by the manufacturer’s authorized service center (Chevrolet dealer) but not by police or insurance representatives. There were warning symptoms before the failure, including: Noticeable shuddering during acceleration Hard shifting, particularly in lower gears Transmission overheating codes detected by the dealership These symptoms first appeared at approximately 35000 miles and have recurred despite prior repairs under warranty.
