2021 Chevrolet Silverado 1500 Power Train

A recall repair was performed on my vehicle at approximately 157,000 miles. Approximately 4,000–5,000 miles later, the transmission failed. The vehicle entered reduced power mode and became stuck in gear while driving. The dealership is recommending full transmission replacement but will not provide written explanation for why the failure is not related to the recall repair. I am concerned the recall remedy may have failed and that this condition poses a safety risk.

Not sure of exact date I believe it was right before Thanksgiving. The truck started shuttering and vibrating. It feels like we are driving on a gravel road. the manual said to change transmission fluid between 45,000 and 60,000 so we took it to the dealer. that is what we did hoping that would fix the problem. but it did not so we took it back and they kept it for 3 weeks they said no codes came up and they said the tires needed balancing so we let them do that but the problem is still there. they say there is no recall on it . we did some research and found information stating Chevy is having problems with the transmission. as of now we only have 45,608 miles on it. It is riding worse now.

2021 Chevrolet Silverado Z71 Sherrod truck with the 6.2 engine came apart (blew up) driving down the interstate at 65 mph. Had truck towed to dealership and was told needed a new motor. Truck has 89,000 miles on it. I was told truck does not meet recall because of the date it was manufactured but was acknowledged that what happened to it is what the recall is for.

CEL on. Lifter failure on cylinder 1.

On a very cold day in January I left work to head home in 4-high. Just before I got on the highway, the truck did a hard shift from 1st to 2nd and I felt kind of a clunk. Truck immediately threw a check engine light and went into limp mode (didn't seem to shift at all). Pulled into a parking lot and tried to go in reverse, but truck would not go into reverse. Truck was towed to local dealership where they diagnosed it with a failed valve body on the transmission. Dealership told me the valve body was on back order so I then towed the truck to a local transmission shop who changed out the valve body. Transmission had no issues before this. The morning this happened it was very cold (below zero) and I got a message in the truck that said, "heater performance mode active". Thought that was weird, but dealer did not seem to think it had anything to do with the failure.

Transmission began shifting hard over between 60500 and 62000 miles. Dealership test drove and confirmed it was not normal. The transmission pan was dropped and contained metal shavings and bits. Dealer replaced transmission. During late February 2026, I began noticing some hard shifts again, but am hesitant to pay another $699 diagnostic fee and replacement transmission cost because I feel I am wasting money on a poorly designed and unreliable transmission. I don’t feel confident relying on this vehicle for transportation to medical appointments anymore.

UNKNOWN. I have had issues with my vehicle since the purchase. Very subtle in the beginning, then it became more noticeable. There was a recall issue with a valve in the operation of the transmission, this issue is now affecting the shifting into different gears. The other day a vehicle ran a red light and my wife and I were in the intersection. I tried to accelerate to get out of the way, but here was a delay before the truck's transmission engaged. Luckily it did engage and the collision was avoided. This is a serious issue, an issue that shouldn't exist, an issue that the manufacturer knew about. I would like someone to investigate this and hopefully, help me with this issue. [XXX] [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On January 3, 2026, I started the truck, but it would not go into gear when I put into drive; I then attempted to put into reverse and same problem. I had to have it towed to the dealership, McCluskey Chevrolet, Kings Automall, Cincinnati Ohio, on Monday, January 5, 2026, this is where I purchased the vehicle on May 14, 2022, with 16,594 miles at time of purchase (estimated), it was towed on a flatbed, and arrived at McCluskey with 60,072 miles. Truck was looked and they found that it needed a valve body. At which time they told me GM warranty expired, over 60,000 miles, really by 72 miles. Ok there is a powertrain warranty then I had to prove oil changes, guess what I'm human and I missed two oil changes so the "extended warranty" McCluskey "gifted me" was void. I then complained I only drove the vehicle 43000 miles and for a 2021 with 60,072 miles this is an issue. Service advisor then went to management and they reduce the cost from est. 4000.00 to 585.00 plus tax through a program that GM offers. Picked up repaired vehicle on 1/30/2026, 2/1/2026 engine light came on went to have a veriscan and it found solenoid 3 stuck off & solenoid 4 (the one that was replaced) stuck on. This is an issue on gas 2021 Silverado 1500 and I wanted to report my experience because this is not "primarily" a diesel problem any longer.

Transmission Shuddering, trembling and rough shifting

Went to put the truck in gear and it will not move the Chevy dealership saids it needs a new transmission and I see that the 21 Silverado has multiple tranny issues I bought extended warranty and they are telling me it might not be covered

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle jerked unexpectedly. The check engine warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the valve body needed to be replaced. The vehicle was not repaired due to parts not being available and the VIN not being included in a recall. In addition, the part was ordered at the owner's expense. The manufacturer was made aware of the failure. The failure mileage was approximately 145,565.

The contact owns a 2021 Chevrolet Silverado 1500. The contact was aware that the VIN was included in NHTSA Campaign Number: 24V797000 (POWER TRAIN). The contact stated that while driving 75 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle pulsated before stalling. The contact was able to coast to the side of the roadway. No warning lights were illuminated. The vehicle was towed to an unknown dealer, where it was diagnosed with transmission failure. The vehicle was not repaired. The vehicle was then towed to another dealer, where the transmission failure was confirmed. The contact stated that the dealer had not inspected the transmission and used a "peephole" to inspect the transmission. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

The powertrain transmission system, specifically the torque converter, failed on my 2021 Chevrolet Silverado at approximately 66,000 miles. The vehicle was taken to and inspected by a GM-authorized dealership, Pellegrino Chevrolet, on January 7, at which time the dealership diagnosed a failed torque converter and formally recommended a full transmission replacement due to the risk that metal debris from the failed converter may have contaminated the transmission; the vehicle and affected components are available for inspection upon request. This failure presents a safety risk due to the potential for loss of power, unpredictable drivability, delayed or failed acceleration, or sudden transmission malfunction, and this vehicle is my family’s primary transportation and is used to transport three child car seats. The problem has been confirmed by the GM-authorized dealership and additionally reviewed by four independent mechanics, all of whom advised that replacing only the torque converter would be insufficient. The vehicle has been inspected by the dealership and documented under General Motors Case #87048318; it has not been inspected by police or insurance representatives at this time. Prior to diagnosis, the vehicle exhibited abnormal transmission behavior and drivability symptoms consistent with torque converter failure, which prompted inspection and worsened leading up to the dealer diagnosis.

No reverse in transmission and sporadic engagement and shifting in forward gears.

While driving vehicle pulling out into an intersection lost power do to Transmission failure (valve control body). Truck was towed to a Chevy Dealer and was confirmed transmission failure. There was no warning or symptoms prior to this incident.

My 2021 Chevy jerks and jumps into gear when putting it into drive from park. This has resulted in the truck jetting off uncontrollably. This has happend several times going back to 2021 but Chevy will not do anything about it.

6 months and 20,000 miles after purchasing the 2021 Chevy Silverado custom 4x4 with the 8 automatic transmission and the 2.7L turbo charged engine with 32,000 original miles on it from Volume Chevrolet in Forsyth GA I noticed the transmission was jerking when the truck was first crunk and warming up after about 10 minutes and once it got to 8 mph after a while when the temperature gauge was half way up it would stop and when you slowed down from 55 mph to about 5 MPH to make a turn it would suddenly jerk again, I reported the issue to the dealership service mechanic shop reps during every oil change and they assured me that it was normal and that it would stop happening when I let the truck warm up for about 30 minutes prior to driving, once the factory power train warranty ran out, they informed me that it needed a transmission service and they would have to keep it a few days and it would cost around $800 or so to get it done, the purge pump on the emissions system has a factory defect and I received a recall letter about it 6 months after purchase and they are refusing to replace the purge pump until they perform a full diagnostic first even though they have done a scan diagnostic and it shows the purge pump failed and I have just been struggling with all the cost of living and increased prices I can't afford any kind of costly repairs right now and my truck now has 120,350 miles on it and the issue is getting worse to the point that I am sure that the transmission valve body and some other sensors and control modules are failing, this is not a single issue and other dealerships have said that the transmission was starting to have problems in other trucks at around 55,000 miles and some earlier than 55,000 miles, I believe that this is an ongoing transmission issue with the 2.7L turbo charged engine in both the 4x4 and 2x4 models and with the 8 speed automatic transmission In general, I have talked with several other owners and they have had similar issues .

Component is transmission. Stutter vibrate shift while driving. There is a recall on the 2021 Chevy 1500 Silverado which is exactly the issue we are having from our 2021 Silverado. The VIN for our truck is falling under the current recall. Chevy wants to charge to even diagnose the problem which has to be done with a dealer and not a private place. That is absurd and puts our safety at risk should the vehicle stop functioning while driving it. The dealer ship has inspected the vehicle for the yearly inspections which is interesting since this has happened and been complained about since purchase.

I was stopped at a stop light and all of a sudden, the engine just revved amd revved and no drive only reverse, and it happened 4 times until tonight, 11/11/25 @ 8:38pm I am stuck at another red light and have to back my truck up to Home Depot and get a tow. Only a 5 year old truck with 71122 miles and ALWAYS WELL MAINTAINED WITH PAPERS AND GOES OUT ON ME. NOT ACCEPTABLE GM! You make things and used to be solid, like a rock trucks but now I feel robbed as a long time Chevy fan/enthusiast but I may have to change manufacturers unfortunately.

The transmission is making a clanking noise during the lower gears. The local dealer said the transmissions is "done for". The truck has around 125,000 miles on it. The truck is available for inspection. When checking for recalls, i saw the GMC were being recalled for the same issue.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the transmission shifted hard while depressing the accelerator pedal. There was no warning light illuminated. The vehicle was taken to the dealer and the TCM was reprogrammed; however, the failure worsened, and the vehicle hesitated while depressing the accelerator pedal. Upon investigation, the contact discovered NHTSA Campaign Number: 24V797000 (Power Train) and linked the failure to the recall. The vehicle was taken back to the dealer and the contact was informed that the vehicle was not under recall. The contact was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The manufacturer was notified of the failure and a case was filed. The failure mileage was approximately 120,000.

The transmission either shifts hard or momentarily locks up when downshifting and then shifting back up into high at 50+ mph. Check engine light comes on, tow haul mode is not available, engine rpm's increase dramatically. Transmission will begin shifting normally after a engine stop, but check engine light stays on, and tow haul mode is not available. Cycle continues. The hard shift before the check engine light comes on and transmission upper gears are locked out is very unnerving, especially with a travel trailer behind you at 65 mph. I no longer fell safe driving the vehicle. I am requesting assistance from the dealership on this truck with less than 49000 miles. The "flash for the transmission" recall was done several thousand miles ago. It only masks the situation. This is not acceptable, nor safe.

I experienced a locking up or no power to the rear wheels. It was raining and the rear wheels would spin. I had no traction. I had to take a few turns and had to be careful or I would have fishtailed into other vehicles. When I stopped at a stop light/or sign then proceeded forward the rear wheels would spin in place. The tires wouldn't grab the pavement. This is the best way I could explain it.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle shuddered and hesitated while shifting into gear. No warning light was illuminated. The vehicle was taken to a local dealer, where the transmission was flushed due to a possible torque converter failure; however, the failure progressed. The vehicle was taken back to the same local dealer, where it remained for further investigation; however, no cause for the failure was found. The manufacturer was not made aware of the failure. The failure mileage was approximately 62,265.
