The failure involves the powertrain, specifically the 10-speed automatic transmission and its internal Transmission Control Valve (TCV) located within the valve body. The transmission has failed, and a GM dealership determined that the entire transmission requires replacement. The vehicle is currently inoperable, and the transmission is available for inspection upon request. My safety was put at risk due to abnormal transmission behavior. GM issued a recall for this vehicle related to excessive wear of the Transmission Control Valve, which can cause abnormal downshifting and, in some cases, wheel lock-up during downshifts. Sudden or unintended downshifting at speed presents a serious safety risk to the driver and others on the road. The failure has been confirmed by an authorized GM dealership, which diagnosed the transmission failure and stated that a full replacement is required. The vehicle has been inspected by the dealership, and the recall remedy was performed in July 2025. The recall consisted of a software update to monitor excessive TCV wear, not a mechanical repair. Prior to the complete failure, there were repeated warning signs, including check engine warning lights. The vehicle was brought to the dealership multiple times in March and April 2025 for check engine warnings. After the recall software was installed in July 2025, the vehicle was serviced again in September 2025 with no issues noted at that time. The check engine light returned in November 2025, and on November 11, 2025, the transmission failed completely, rendering the vehicle unsafe to drive. Despite proper maintenance and multiple service visits addressing warning indicators, the transmission failed prematurely at approximately 74,000 miles. Given the known recall related to excessive TCV wear and the nature of the failure, this appears to be a defect-related powertrain failure rather than normal wear and tear.

My 2021 Chevrolet Camaro has experienced repeated transmission-related issues and has now suffered a complete transmission failure at approximately 74,000 miles. GM previously performed the Transmission Control Valve (TCV) recall on my vehicle, but the recall was only a software update to monitor for excessive valve wear. It was not a repair. The recall notice states that excessive TCV wear can affect hydraulic pressure, torque converter lockup, and downshifting behavior, and GM created software to continuously monitor for this excessive wear to prevent a potential wheel-lock condition. Despite this, my transmission has continued to have problems. In March 2025 I brought the vehicle in for a check engine light, and again in April 2025 for additional transmission-related issues. The service history does not clearly state what repairs were performed, only that transmission service was done. We have brought the vehicle in multiple times for check engine lights and for all recall updates.In Nov 2025, the transmission began to fail completely. The dealership has now advised that the entire transmission needs to be replaced. A transmission does not require full replacement unless significant internal wear or component failure has occurred. Excessive internal wear is the exact condition the recall software is designed to monitor for. GM has stated there are “no known failures after the recall,” but my case clearly contradicts that. The recall was primarily aimed at preventing a lock-up safety event, not mechanical deterioration. Excessive TCV wear can still cause progressive internal transmission damage over time, even after the recall software is installed. This failure affects the safe operation of the vehicle, including loss of power, unpredictable shifting, and potential inability to accelerate. GM is refusing to fully cover the repair and is only offering partial goodwill coverage despite the failure of the excessive wear condition identified in the recall.

The contact owns a 2021 Chevrolet Camaro. The contact stated while driving at an undisclosed speed, the vehicle briefly jerked and jolted before returning to normal functionality. The contact stated that the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that a software update was needed. The vehicle was repaired, but the failure reoccurred. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 25V148000 (Power Train); the VIN was included, but the vehicle was already repaired under the recall. The manufacturer was not notified of the failure. The failure mileage was 80,000.

I AM NOTIFYING NHTSA OF THIS INCIDENT FOR THE RECORD. I PURCHASE THIS VEHICLE ON 9/30/2020 ... AFTER 3 SHORT TRIPS TO KEEP FLUIDS MOVING AND THE BATTERY CHARGED DURING THE BREAK IN PERIOD THE CAR HAS BE SETTING UNDER A CAR COVER WITH 426 MILES ON IT. I AGAIN STARTED TO GO FOR A RIDE ON 1/17/2021TO DO ANOTHER BREAK IN RIDE. THE CAR STARTED WELL AND WHEN I PUT IN DRIVE I NOTICED A SHUTTERING AND THE TRANSMISSION INABILITY TO SHIFT SMOOTHLY. AFTER JUST A FEW MILES I NOTICED SHIFTING AND SLIPPING WAS STARTING TO BE MORE FREQUENT SO FOR SAFETY REASONS I BROUGHT THE CAR BACK HOME. WHILE TURNING INTO MY STREET THE CAR TRANSMISSION FAILED AND SLIPPED AND STOPED IN THE MIDDLE OF A TURN JUST NARROWLY AVOIDING AN ACCIDENT. THE TRANSMISSION IS ALL OVER THE PLACE WHEN SHIFTING, ENGAGING AND TAKING OFF. THIS CAR CAN NOT BE DRIVEN SAFELY AT THIS TIME IT IS NOT SAFE AND I FIND OUT THROUGH RESEARCH IT IS AN ONGOING PROBLEM WITH GM WITH LITIGATION IN PROGRESS ON THIS ISSUE. WHY AND HOW CAN GM STILL SELL THESE CARS WITH THIS ISSUE STILL PRESENT. I CAN NOT TAKE A CHANCE WITH THIS CARE AS IS MY LIFE AND THE LIFE OF MY FAMILY DEPENDS ON IT. .THANK YOU IN ADVANCE FOR YOUR ATTENTION AND SUPPORT WITH THIS MATTER.

The coolant thermostat is not working correctly and could possibly cause you to damage your car due to it not being the right operating temperature or over the normal operating temperature because it goes down into the 130 while I drive and goes up when I start slowing down.

there is a burning oil smell, that is so pungent it causes nausea and burning of the eyes when driving the vehicle. have taken it to 2 separate dealerships, the first told me they could not find an oil leak and i would have to deal with it. the second dealership stated that it is a valve on the back of the motor and that there is nothing they can do about it. i was told not to roll down the windows and to leave recirculate on. called and spoke to gm directly and they state take it to a third dealer and they denied my request to send a master tech to check the vehicle. i am left with driving a car that leave me nauseated and is a possible hazard to drive.

* 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 NHTSA 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.

WHEN OPERATING THE CAR IT BEGAN TO SLOW DOWN. ONCE I APPROACHED A STOP THE CAR ENGINE SHUT OFF. AFTER A FEW MINUTES I WAS ABLE TO START AGAIN. AFTER I DROVE THROUGH THE LIGHT AND PROCEEDED HOME ABOUT 2 MILES AWAY FROM THE INITIAL STOP, THE CAR SHUT OFF AGAIN. IT WAS SENT TO VANDERGRIFF CHEVROLET IN ARLINGTON, TEXAS AND THE ISSUE THEY SAID HAD SOMETHING TO DO WITH A CAM MAGNET- THIS WAS NOV 2021. TODAY- NOVEMBER 7 2022 THE SAME THING HAPPENED AS I WAS HEADED TO THE STORE. I DROPPED THE CAR OFF YET AGAIN FOR REPAIR. THE SERVICE ADVISORS DIDN'T KNOW HOW TO FIX IT AND HAD THE CAR FOR TWO WEEKS. THEY EXPECT TO HAVE IT FOR ANOTHER WEEK TO ASSESS AND DIAGNOSE THE PROBLEM BUT THE FACT THAT THE CAR HAS SHUT OFF MORE THAN 3 TIMES IS UNSAFE.

We were hit perpendicular to the passenger side door of our 2021 Camaro. The side airbag(s) did not go off. The other vehicle was going about 15-20 mph upon impact. The right side of our car was seriously smashed in. Its a good thing the passenger was not killed or injured and this is a law of physics abnormality.
