Power Train Problems of Chevrolet Tahoe - part 1

Chevrolet has a recall on some vehicles for a bad transmission valve body, but my vehicle isn’t a part of the recall and I’m having the exact same issues. Currently my only vehicle that I have to transport my 7 month old is a complete safety risk. My check engine light is on and the code its throwing is to replace transmission valve body assembly. My Tahoe is shifting very harshly when driving normally, it feels like it slams into gears causing the whole car to jerk. When sitting at a red light that turns green, Tahoe is slipping, barely wanting to move through an intersection with vehicles all around me. I’ve been advised to not drive my Tahoe at all because if I do I will certainly have severe drivetrain damage and rear wheel lock up. Like I said, Chevrolet already has a recall for this issue on some of their vehicles, but my specific Tahoe does not. This is my only vehicle for myself and my baby and I cannot drive it due to its safety issues.

On June 12, 2026, while operating my 2025 Chevrolet Tahoe, I experienced an apparent powertrain or transmission-related issue. At the time, the vehicle was already exhibiting another defect involving the air conditioning system, with the driver's side blowing hot air and the passenger side blowing cold air. While attempting to accelerate and pass another vehicle, the engine rpm suddenly increased to approximately 6,000 rpm. The rpm remained elevated momentarily before gradually decreasing. The vehicle's response was abnormal and inconsistent with normal acceleration. Because I was close to home, I continued driving but remained concerned about the vehicle's operation. Since that incident, the same condition has occurred approximately two to three additional times. The problem is intermittent and does not occur every time I accelerate, making it difficult to predict when it will happen. This condition creates a safety concern because sudden, unexpected increases in engine rpm while attempting to accelerate can affect vehicle performance and driver confidence, particularly when passing other vehicles or merging into traffic. The vehicle is being returned to the dealership for evaluation, and the defect remains unresolved.

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.

I recieved this message after bringing my 2019 chevy Tahoe to the dealership today for regular maintenanceand to check out a slight noise coming from under my hood: rotational noise in your engine compartment had to remove the belts to be able to isolate where the sound was coming from. The noise is coming from the camshaft inside your engine so we know that is going bad. He also noticed that the engine mounts are worn out, oil cooler lines leaks and water pump leaking. I have kept up all required/recommended maintenance on time and didnt have any reason to believe I needed anything more then belts replaced and fluids changed when I took my truck to the dealer. After recieving that message, I spoke with the manager at the dealer and he said its a common issue. I've loved on my vehicle and value it as it is my only vehicle that transports my 2 children and myself around. Therefore im confused how this could happen outside of a manufacturer defect. There werent any warning lights, just a slight chirp coming from under the hood which sound like maybe a belt was going. The truck is at boniface chevy melbourne florida where I purchased it from.

My vehicle started having stuttering/shifting issues back in August 2025, I was advised the vehicle did not need new engine but upgraded oil. I continued to have the issues and have continued to bring back to dealer for constant software updates - cannot duplicate issue meanwhile the stop sale order was issued and I was not advised. The vehicle then experienced very hard jerking- stall- that lead to the dealership putting an awd in 2wd calling it a fix! just got vehicle back again after a complete stall at a stop sign- causing vehicle to roll back and cut back on! dealer stated the vehicle showed the stall/shutter but could not duplicate on road test. This is a serious safety issue!!.

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.

My 2017 Chevrolet Tahoe equipped with a 6l80 transmission began experiencing transmission-related drivability issues at approximately 130,000 miles. The vehicle jerked on takeoff, had delayed/slow shifting, produced a whining noise, and later had intermittent shuddering/surging while driving. During service, metallic debris/shavings were found in the transmission fluid. The transmission ultimately required replacement at my expense. I am aware of gm technical service bulletin 20-na-142, “shudder/surging while driving,” which includes 2015–2022 Chevrolet Tahoe models equipped with myc/myd transmissions and discusses conditions that may be identified as torque converter shudder. My vehicle’s 6l80 transmission corresponds with gm rpo myc, and the symptoms/repair findings appeared consistent with the bulletin. I am filing this complaint to document the transmission failure and related safety concern, as the jerking, delayed shifting, and shuddering affected normal vehicle operation.

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.

***safety/danger*** on April 12th at around 5:30 p. M. My family of five, to include three minor children were returning home from visiting family which live about an hour and a half away and as we're traveling on the freeway at highway speeds, in traffic, our new Tahoe unexpectedly and without warning went into reduced power mode and cut speed down to approximately 35 mph in active traffic, which out my family and every other car around me in danger and in jeopardy of causing a collision and even worse, a multiple car pile-up as I dodged full speed traffic in front and behind me while traveling at approximately half their speed. I managed to exit the freeway and heard a loud knocking noise from the engine and saw the reduced power mode indicator, all of which had not happened before but again, the Tahoe is relatively new and was just over 5 months and at 8,889 miles at failure. I proceeded to contact gm roadside assistance. They sent a tow truck and I had to make arrangements for my family to return home, an hour away. I made it to the dealership with the tow truck driver after 9 p. M. ***catastrophic damage**" after the dealership inspected close to a week later they did determine that the entire engine and turbocharger had to be replaced, which they did in a little over a month, the dealership did their part but confidence is lost. Now I am hesitant to drive the Tahoe as it's the family vehicle but really put my kids, wife, myself and everyone around us on the road in danger as it, out of nowhere, cut speed drastically in active highway traffic.

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.

We have a 2021 chevy. Tahoe, and we just had an inspection done because a light kept coming on saying that our engine might fail. The shop initially said it needed cam shaft replacement, but now are saying the entire engine needs to be replaced. The care has ~ 67,000 miles on it and is 5 years old.

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.

Rear end makes noise when turning, been flushed based on current bulletin. Still makes noise but not as bad. Now transmission is jerking at multiple gears.

While driving down i35 south of wellington KS in our new 2026 chevy Tahoe we experienced a vehicle shift to neutral and no transmission correction available. 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.
