Chevrolet Tahoe won't shift problems

Filed Oct 13, 2026 · Transmission · TX

My car on the dash board said do not accelerate and was shaking and the gear would not go into reverse. When I tried the car would not move. I towed the car to local Chevy dealer and when I told them about N242454441 or related safety campaigns like N242454440 nothing came up for my VIN but was informed GM had this program specifically for my code ( check engine light on) reading P0776 and P0700. This was not covered.

I am reporting a transmission failure involving my 2022 Chevrolet Tahoe Z71, VIN [XXX]. In XXX, while driving, my Tahoe became stuck in Drive and would not shift into Reverse. The transmission then completely failed and the vehicle could no longer be driven normally. I took the vehicle to a Chevrolet dealership, where the transmission failure was diagnosed and replacement was recommended. GM’s quoted replacement cost was very high, so I had the transmission replaced by an independent mechanic in [XXX] using a certified GM replacement transmission. I subsequently became aware of the federal safety agency recall 26V085 / GM N252536750 involving certain 2022 Chevrolet Tahoe vehicles with the 10-speed transmission. The recall involves a transmission control valve that may fail and cause loss of transmission function and, under certain circumstances, rear-wheel lockup. My Tahoe’s manufacturing date is XXX, so I understand it is outside the currently identified production range for this recall. However, my vehicle experienced a complete transmission failure with an inability to shift into Reverse. I am requesting that the federal safety agency review this failure to determine whether the original transmission may have experienced the same or a related defect and whether vehicles outside the currently identified production range may also be affected. The Chevrolet dealership that diagnosed the failure may have diagnostic records, trouble codes, and transmission identification information for the original transmission. I can provide these records and the independent repair documentation if needed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On September 19, 2026, while traveling approximately 30 mph, the vehicle experienced a sudden, hard shift. The check-engine light then illuminated. I pulled over as soon as it was safe to do so. After stopping, the vehicle would not shift into reverse and entered limp mode. The transmission malfunction created a safety risk because the vehicle’s operation and available gears became restricted unexpectedly while it was being driven. The loss of reverse also prevented the vehicle from being maneuvered normally. The vehicle was not driven after the incident and was towed from the location. The vehicle and affected components are available for inspection upon request. At this time, the vehicle is awaiting inspection and diagnosis to determine the exact cause of the transmission malfunction.

2022 Chevy Tahoe went into limp mode at 62,500 miles out of the blue and check engine light came on. At the certified Chevy dealership I was told it was the transmission control valve, Code P2732, which is a known widespread factory issue in these models. Upon further inspection, was told my transmission fluid was completely black and burned and it ruined the transmission and therefore it needs to be replaced. "Consequential Damage Policy: When a control valve body fails and stays "stuck on," it forces maximum line pressure through the system. Continuing to drive under these conditions quickly destroys the internal clutch packs, burns the fluid, and melts down the transmission." This is exactly what happened and my vehicle was never put on a recall list but clearly was a ticking time bomb.

I purchased my vehicle new in 2020. It presently has around 83,000 miles. From early on, it has occasionally hesitated, then jumped when putting the car in reverse. I spoke to the dealership years ago but they said it was nothing. On July 19, 2026, my car randomly would not shift above (probably) second gear on the highway. After parking, it would not shift into reverse at all. The vehicle was towed more than 30 miles to my hometown dealership as it was inoperable. It now requires something approaching a transmission replacement costing between $2500-4500, or more. I am aware that this is a recurring problem with GM vehicles of this type and era, and it seems absurd to have so many vehicles with failing transmissions before they even reach 100,000 miles.

Driving the vehicle down the highway at approximately 65 miles per hour, the check engine light came on and the engine went into limp mode, slowing immediately. Upon getting the vehicle to the left shoulder on a busy highway, the vehicle displayed "engine overheating", "battery low", and 0% oil life. A full oil and filter change had been done less than 1000 miles ago and upon checking the oil, it was at the correct level. The engine completely failed and is not being replaced at a Chevrolet dealership. I completed the recall N252494003 on March 5th, 2026 which comprised of an engine inspection, higher viscosity oil, a new oil cap, filter replacement, and owner's manual insert. The engine still failed and required replacement despite having this done.

My vehicle would not shift into reverse. Took it into the Chevrolet service and they said the Valve body needs replaced. There are known issues with the Valve body in 2021 Tahoe but they said it is not covered under any of the GM extended warranties. It should be covered under Special Coverage N242454441 or N242454440, but they said no coverage. The vehicle only has 46,200 miles on it

Garage reports the transmission is 'bad' . Awaiting dealership input but 3 weeks before they will look at it .

I was leaving my neighborhood on Saturday night 5/16 around 5:30 and on the way out all of a sudden the dashboard started lighting up and the speed was dropping despite me being on the gas. The screens kept flashing then the car stopped and went into park and I could not get it out of park. I was at the front of my nieghborhood entrance and it made it hard for others to come in and out. I tried to restart it. My husband tried to jump it. I tow truck came about two hours later only to realize it could not tow it since the vehicle was stuck in park and could not be powered to move it to neutral. They had to call a new tow truck. I was sitting in my car stuck in the entrance of my neighborhood impeding traffic for close to 4.5 hours. A new tow truck finally arrived at close to 9:45pm. It was towed on dollies to the dealership. They inspected it today and said the starter and the engine had both failed/blown and needed full replacement. I am waiting to hear back from them on the estimated time for replacement biut could take weeks which is devastating. My vehicle is the 2025 Chevy Tahoe High Country with the 6.2 L V8 engine that I now understand has issues prior to 2025 and was recalled but nothing yet for the 2025. My car is only 9 months old and has 12,100 miles on it. I am devastated. Prior to this I had no issues and there were no sounds or issues it just happened. It was dark by the end and I was sitting in the middle of the road and the lighting in the area is limited so I had to have someone bring me lamps so other drivers could see me as the car is black and it was very dark. Someone almost hit me pulling into the neighborhood as a result thankfully I was able to get lamps.
