My vehicle has suffered a transmission control valve failure (stuck open). This is the exact mechanical failure detailed in gm’s nationwide recall n24245441-02. It is deeply disheartening and illogical that my vehicle—which shares the exact year, make, model, and identical mechanical failure detailed in the safety bulletin—is excluded from the recall purely due to an arbitrary VIN filtering process.

My 2017 Chevrolet Tahoe lt 4wd with a 5. 3l engine experienced sudden drivability issues related to confirmed afm lifter failure, including severe engine misfires (p0300), rough idle, shaking at stoplights, and significant loss of power while driving uphill and under load. The vehicle has approximately 140,000 miles and has been consistently maintained through Chevrolet dealerships. The condition has been diagnosed by premier Chevrolet of carlsbad. The engine experienced loss of power during operation, creating a potential safety concern when accelerating or driving in traffic conditions requiring consistent engine power. This issue appears related to widely documented afm lifter failures on gm 5. 3l engines.

Engine stopped while driving 70 mph down the highway and the car shifted into neutral. Had to cost to side of the road. Took car into dealership and even though the car was certified safe drive and the engine had no issues 5 months ago, I was told the engine was now locking up. The engine failed despite using the higher viscosity oil that chevy recommended. These greedy cunts at chevy placed me and my family's lives in danger to save a buck; they knew that the engines would fail and instead of replacing the engines, they put thicker oil in the cars to hopefully get the cars past warranty.

The engine randomly shut off while driving down the interstate and wouldn’t start back up. The car had the recall “remedy” done to it. Inspection and thicker oil. The only warning I got was to restart the engine after it shut off. My safety was compromised by breaking down on a main interstate coming through memphis with no emergency lane to pull over in.

Car got stuck between gears while driving on the road. The vehicle accelerated by itself almost causing me to crash. I immediately pulled over into a business and put the truck in park. The car stayed on. It turned on and off but would not shift gears. Would not go from park to reverse or drive. And unfortunately the “warranty” only cover 60k miles. Conveniently right before this well known issue goes out. The main issue was pressure control solenoid c stuck on. This issue is an issue many people are having and since it is a drivetrain issue this can affect many lives while on the road.

At less than 50,000 miles, my alternator went out and had to be replaced, causing the battery to need to be replaced also. Now, at only 51,000 miles, my transmission is having problems and causing the vehicle to jerk when shifting. This vehicle has had regular maintenance performed by a combination of dealers and certified service centers since it was purchased brand new. I have never had this much trouble with a vehicle and am very concerned about it's overall safety and integrity, given the severity of the problems for something that is not old and does not have high mileage.

The component at issue is the engine, which suffered a sudden and catastrophic failure due to unknown causes. At no time prior to this incident were there any warnings, symptoms, or indications of an underlying mechanical defect that would have allowed for preventative action. While operating the vehicle on the highway with my family present, multiple warning indicators activated simultaneously, including a blinking check engine light, traction control light, esc warning, and a forward collision warning. Immediately thereafter, the vehicle experienced a rapid and significant loss of power accompanied by a loud and persistent engine knocking noise, rendering the vehicle unsafe to operate and placing the occupants at risk. It is important to emphasize that traction control and esc systems are not causally related to an engine misfire condition, further supporting that this event was abrupt and not part of a progressive or diagnosable issue. A diagnostic scan performed at that time identified a misfire in cylinder 1. Upon delivery of the vehicle to the dealership for inspection, it was determined that the engine had suffered complete internal failure and was deemed “blown. ” this finding confirms the occurrence of a catastrophic mechanical breakdown. Based on the sudden onset, absence of prior warning, and severity of the failure, there is no reasonable basis to attribute this condition to normal wear and tear, operator misuse, or neglect. Rather, the facts support the conclusion that this was the result of a latent defect or internal mechanical failure beyond the operator’s control. Accordingly, this matter should be addressed under applicable warranty coverage or consumer protection standards.

My Tahoe has 108,000 miles on it. It broke down in the middle of the road and refused to go into gear with zero symptoms prior to this. We had it towed to the dealership and were told it is the transmission valve body. This is a known issue but our VIN isn't covered for some reason so we have to pay out of pocket for this costly repair that is a known problem!.

I had the car in for a message (service transmission now will not be able to shift soon). They told me there was nothing wrong with my transmission it was a parking brake sensor issue. They ordered me a new sensor and never called to tell me it was in. I followed up and they said they had the part and I could come in whenever. They said it was not a safety issue and would be a quick fix. I had an appt today and to my surprise when I went to drive to the appt my car will not let me shift out of park with a new message (service transmission, unable to shift). I am now waiting for the car to be towed. This car has had nothing but issues including the back-up camera not working properly for 2 years. These are all serious safety concerns that chevy/gm has not properly handled.

Coasted to ditch saw “service transmission” notice and so turned off and on engine . Went to derby KS and davis moore chevy in wichita where staff removed the warning service notice on driver info and we continued to molle chevy in blue springs mo. Where they did diagnostic and only showed ambient air fault!! this is scary! we had no transmission and had to get off road safely! please let public and our dealers know and recall all vehicles with this problem. We are afraid to drive this new 3,000 mile chevy Tahoe.

I was driving yesterday and noticed my transmission started to shift hard and unnecessarily. Then I received a warning that propulsion was affected and to drive with care. The check engine light came on. I was able to make it home, but the vehicle wouldn't go into reverse. I had it towed to a dealership today and they identified the issue as being related to the valve body. Apparently a recall was just issued for this on the 2022 chevy Tahoes. I'm not sure why this isn't being extended to the 2021 model.

Transmission issue -while driving 55 mph the rpm’s revved up and the vehicle felt as it it was in 2nd or 3rd gear. Warning lights came on stating “rapid deceleration use caution” and the engine light came on. The vehicle was able to go into park but upon shifting back into drive, it did not change gears. Sounds as if it is being driven in 2nd or 3rd gear with rpm’s elevated.

Driving down the highway and I lost all the gears it went from driving speed then wouldn’t go over 30 mph. When I got pulled into a business on the side of the road then tried to restart it it then wouldn’t go into reverse. It was dangerous because there was cars behind me going the speed limit then my car just lost speed. No warnings it’s not throwing any codes. Looking on the internet it seems it’s the transmission or valve body.

At 64000 miles my 2019 chevy Tahoe has to be replaced due to lifters failing. Gm/chevy wants to charge me $17000 to install a new 6. 2l - v8 engine. (same engine that had the lifter problem). That engine has been recalled on earlier and later models. What do I do to fight the cost of new motor ?.

I was driving when I noticed my vehicle lagging and possibly misfiring, and then the "service four-wheel-drive" warning appeared. I was just down the road from my house, so I pulled into the driveway and put the car in park, but it wouldn’t turn off. I realized the parking brake was engaged and wouldn’t release either. I was stuck in two-wheel drive and couldn’t switch to four-wheel drive, and the emergency brake wouldn't disengage when I pressed the button, so the vehicle still wouldn't shut off. I had to put it in reverse physically step on the gas, which is the only way the parking brake finally disengaged and allowed the vehicle to shut off.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle lost motive power, and the transmission slammed into gear, and it felt like the vehicle was rear-ended. No warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with transmission valve body failure. The contact was informed that the transmission valve body needed to be replaced. The contact was later informed that the transmission needed to be replaced. The vehicle was being repaired. The contact stated that the failure was a known failure with the vehicle. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the NHTSA hotline to report the failure. The failure mileage was approximately 62,000.

While driving my 2021 Chevrolet Tahoe at highway speeds (approximately 60 mph), the transmission suddenly malfunctioned due to what the dealership is telling was a valve body failure. Without warning, the vehicle lost proper propulsion and began to decelerate rapidly in active traffic. I did not receive adequate warning before the failure occurred. The sudden loss of power at highway speed created a very dangerous situation. Vehicles behind me had to brake abruptly, and I was nearly rear-ended. This presented a serious safety risk to me, my three children, and surrounding drivers. The issue was later diagnosed as a transmission valve body failure. A failure of this nature should not occur on a relatively new vehicle, and there is currently a recall on other 2021 Tahoe’s for this same issues. My car is sitting at the chevy dealership waiting for a full valve body replacement, which the dealership said they are having issues getting the part and will take over 2 weeks. The cost is around 5k to fix.

The manufacturer was informed of the failure and a complaint was filed. The failure mileage was approximately 48,000.

Lifter failed on my chevy Tahoe 6. 2l engine at ~75k miles in September 2025. One lifter bank was replaced. No reason for lifter failure was given. Less than 5 months later the other lifter bank has failed and damaged the cam shaft. Again, no reason for failure was provided. Failed lifters can cause catastrophic engine failure, which is incredibly dangerous when the vehicle is in motion. No check engine lights or and warnings occur with the lifter failure, it is only identified by the driver through the tapping noise from the engine. Even a cursory review of forums and complaints reveals that lifter failure is widespread on this engine and that manufacturing defects have caused issues with this power train dating back to 2019, not just the recalled 2021-2024 models.

Transmission has had a failure to shift problem on several occasions resulting in deceleration and a decreased ability to accelerate. This has occurred on most occasions at highway speeds while passing a vehicle causing a very unsafe condition. Dealer has evaluated and determined the transmission valve body is defective and needs replaced. Upon researching the problem, many similar gm vehicles are experiencing the same issue.

My transmission just randomly went out. I had my car evaluated in December of 2025 and nothing was reported on the transmission at all and as Jan 2026 my transmission went out.

Truck bucked twice in high-speed lane of the highway, gas pedal went soft and we luckily were able to coast the truck to the side of the highway without getting hit. The truck put itself in neutral when we lost the engine and the truck would not restart. It had to be towed, while me and my two kids stood on the side of a dangerous highway for 45 minutes in the snow. The truck has 52,000 miles, engine was already replaced at 10,000 miles. It just passed the recall inspection and had the upgraded oil that was recommended.

* sudden catastrophic engine failure. * the car lost power in the middle of a high traffic, very dark country road, forcing her to stay in the middle of the (undivided) road in the dark hoping cars didn't slam into her. A collin county sheriff was dispatched to keep her safe until the tow truck arrived almost two hours later.

2021 Tahoe with 3. 0l diesel engine and 139k miles recently began overheating when on interstate but temp would jump up quickly then quickly back down. Reduced acceleration mode is triggered and ac is turned off automatically. Diagnostic report shows coolant control valve error code and it was explained to me that valve is sticking then as engine pressure rises, it knocks it loose again explaining the quickly jumps and dips in temp. Fan runs constantly from moment it is started too. When looking for the part online to get an idea of repair cost, there was a bulletin about this being a known issue in the 2021 Tahoes with the diesel engines and bulletin states gm extended special coverage for 15yrs/150k miles. When I called dealer to schedule service, I was told this bulletin doesnt come up under my VIN number despite it having the same issues, error codes, year, make, model, and engine.
