Power Train Problems of Chevrolet Tahoe - part 1

The transmission began slipping at 20, 25, 35, and 45 mph by the time we hit 80k miles. The vehicle was out of warranty. We were told it was unaffected by the recalls and not related to the issues affecting other drivers. It now has 167k miles and we have tried having the transmission flushed but it still slips and needs a new transmission. Chevy knows about these issues and refuses to replace their horrible product since they also sell the cure to the problem and make money off of it.

I have a 2023 chevy Tahoe with 45k miles. Today driving two kids home from our football practice I was driving along at around 40mph and all of a sudden the transmission downshifted and almost locked the rear tires up. If it was winter, wet, or cool, there is no doubt that the tires would have locked up. Check engine light came on, and now the vehicle wont move in reverse and at around 45-50 mph the engine is running at 3,000 rpms. I volunteer to be a youth football coach and always have a car full of children. This isn't normal or safe. P. S. I should've bought the Ford expedition.

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.

My transmission completely went out at 130,000 miles. We had to buy a whole new transmission. It has had regular maintenance on it. Rpm would skyrocket the car wouldn’t move. Then it would finally go but not very fat or will. It also was making a terrible grinding noise.

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.

Out of nowhere without any warning light all of a sudden couldn’t back up when geared into reverse to reverse. Turned the vehicle off and back on, then was able to reverse. Left parking lot and was on the road and vehicle started loosing speed, then put into park with hazard lights. When attempting to get off the road for safety reasons tried putting into drive and the car then drove in reverse. Local fire department came and called in the local police dept for assistance and pushed vehicle off to the side and tow company came and took to the auto shop with information today of the transmission going out, and with that causing happening causing the fluid to smell burnt and full. The auto shop test drove and made it 30 feet and would not move. Transmission is failing and causing the concern.

This 2025 Chevrolet Tahoe has experienced three separate and recurring engine-related failures. The first failure occurred at approximately 41,350 miles and required replacement or repair of the lifters and camshaft. The vehicle remained at the dealership for approximately 15 days. The second failure occurred at approximately 54,619 miles and involved another lifter failure along with traction control problems. The third failure occurred at approximately 65,140 miles. The check engine warning light illuminated while the vehicle was being driven, and the vehicle again experienced engine-related problems. The vehicle has now been at the dealership for more than one week, and no repair or permanent solution has been provided. I am concerned that these repeated engine failures and traction control problems create a serious safety risk, particularly because the vehicle is driven on public roads and highways. Despite previous repairs, the engine problems continue to recur. I am requesting that NHTSA investigate these repeated safety-related failures.

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.

The automatic transmission on my 2021 Chevrolet Tahoe (gasoline engine, 10-speed 10l80 transmission) has been exhibiting intermittent slipping/skipping during gear changes, particularly during acceleration and deceleration. The transmission component is available for inspection upon request. The malfunction poses a safety risk as the unexpected hesitation and rough shifting creates unpredictable vehicle behavior at highway speeds and during merging, increasing the risk of a collision with other vehicles. The problem has not yet been formally confirmed by a dealer or independent service center, however a knowledgeable automotive advisor has assessed the likely cause as moisture contamination of the transmission fluid, which degrades lubrication and causes erratic shifting behavior, known issue in several gm vehicles, but the only recall related to this issue is for just diesel vehicles. I contacted general motors customer service regarding this issue and was directed to file this complaint with NHTSA, as gm stated they were unable to attach or create a related existing recall to my vehicle. The vehicle has not been inspected by police, insurance representatives, or the manufacturer at this time. I am in the process of scheduling service at a transmission specialist. No warning lamps or dashboard messages appeared prior to or during the shifting malfunction. Symptoms first became noticeable at 85,000 miles, and have continued since.

-on the date of Monday June 22,2026 at approximately 4:30 pm est I was traveling on s cedar st in holt michigan and transmission felt like a possible slip happened in transmission. At approximatively 4:45pm est I made it home tried to back vehicle into parking space and reverse was lost. Vehicle didn't and wouldn't shift into reverse. I had to push vehicle in spot backwards. No check engine or warning lights were displayed on dash. - on Tuesday June 23, 2026. I contacted feldman cheverlet of lansing michigan approximately at 8:30 am est. Mark callahan answered. I explained the symptoms and asked if I could bring in within the hour or so. He stated it would be fine to bring in. - at approximately 9:10 am est my girlfriend and 22-month-old daughter got in vehicle. Started vehicle no service lights were on, but had no reverse still no reverse. My girlfriends mother was following us to pick us up at dealership as we dont have a 2nd vehicle. We started out driveway to 2455 aurelius rd holt michigan. I had no problems at 1st then prior to the intersection of dell rd holt michigan the vehicle lost control on its own. The sequences happened fast and abrupt. 1. Vehicle downshifted roughly to about 3 gear 2. Lost power steering 3. Engine over revved 4. Vehicle pulled right. During this time as a professional trained driver. I removed us off aurelius rd off road way on to dell rd (to the right) to avoid being in an accident. I would say that the speed was roughly 20mph at turn as I was avoiding the accident that could of potentially happened. I was not on asphalt the whole time to make turn as I had a limited vehicle (not properly functional). I was able to stop at brigantine dr to stop. Stopped on brigantine is when I pointed out to my girlfriend that the lights just came on. In the meantime, we received a phone call from jolynn (girlfriends mom) asking where we went as she didn't see us. We explained to her situation, and she met on brigantine and followed us to dealership.

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.

Date: 06/17/2026 the engine shuts off without warning while I am driving, recurring roughly every 10 miles. When it stalls, the dashboard and electrical accessories stay on, but the vehicle loses motive power, along with power steering assist and power brake assist, which is extremely dangerous at road speed and in traffic. This began immediately after dealer service completed on 6/18/2026. During that visit the dealer performed two safety recalls (n252494000, the "l87 engine loss of propulsion" picoscope inspection with oil change; and n252510321, ecm software reprogramming) and a valve lifter replacement that required removing both cylinder heads. The vehicle was running and fully drivable when I dropped it off, and was returned stalling repeatedly while driving. It never did this before the service. At first the engine would not restart after stalling. The dealer replaced the starter; it now restarts but continues to stall every ~10 miles. A dealer diagnostic scan recorded numerous "lost communication" codes across nearly all control modules, plus control-module input-power codes showing low voltage and power-circuit correlation faults (e. G. , u3505, u3018, u3007) and an active loss-of-communication code for the power steering module — consistent with an intermittent loss of electrical power or ground affecting engine control. The engine passed the recall's connecting-rod/crankshaft (picoscope) inspection, so this is not the recalled bearing failure mode. The vehicle is currently at the dealership and is undrivable. The dealer has ordered a new engine and apparently also a new radiator for reasons unknown. No crash or injury has occurred to date, but the vehicle lost power while on the freeway at speed multiple times. A gm customer assistance case is open. Repair orders and the diagnostic scan are available on request.

The engine's dynamic fuel management (dfm) lifter failed and damaged the camshaft at around 70,700 miles. The broken components are available for inspection upon request. This failure put occupants at risk because the vehicle suddenly lost power, began shaking violently, and could not accelerate safely in traffic. This unexpected loss of propulsion created an immediate collision hazard. The problem was officially diagnosed and confirmed by a repair service center. It has not been inspected by police or insurance representatives. There were no advance warning signs. At the exact moment of the failure, the check engine light started flashing, the car began shaking heavily, and the engine made a loud knocking sound.

My transmission failed, yes it is available for inspection. The failure occurred without warning. I was driving my truck on the highway, suddenly it began to hesitate and making a loud winding out noise. The truck was hesitate on going forward. Yes, I had the vehicle towed to banks chevy, I was told the torque converter blew metal shavings into the transmission and it was a common problem with these vehicles. No warning at all, I just had my oil changed at the dealership, it was running great, out of nowhere this happened.

Unexpected acceleration.

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.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at 40 mph, a warning message advising to reduce acceleration was displayed, the check engine warning light illuminated, and the vehicle stalled. The contact was able to pull over safely. The contact stated that the failure was recurrent. The dealer was notified of the failure and diagnosed the vehicle with a valve failure. No further information was available. The manufacturer was notified of the failure. The failure mileage was approximately 57,000.

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 transmission failed and it has been in a shop for 2 months. The pistons in the transmission failed not sure why but made it not go in reverse. The parts were on backorder for atleast a month. The warranty is out and my extended warranty will not pay because chevorlet dealership failed to flush my transmission when it was in for service. The transmission is a known problem on these models and was recalled for the diesel models but not the gas models.

Transmission failure at 127,000 miles. Multiple flairs in transmission resulting in total rebuild.

Transmission failed. Only warning was check engine light on 10 minutes prior to failure. At 30 mph on city road car was suddenly coasting, engine rpms revved to 7-8k, no driving power available for approximately 30 seconds. 'drive' reingaged but apparently in limp mode enough to get a few hundred yards more to parking lot. No reverse gear available and warning on dash 'catastrophic failure' imminent. Garage reports the transmission is 'bad' . Awaiting dealership input but 3 weeks before they will look at it .

The contact owns a 2009 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the contact noticed oil leaking from the vehicle with the transmission warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the jb weld and the driveshaft had failed, causing the transmission to fail and needed to be replaced. . The vehicle was not repaired. The dealer was contacted;. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was not available. The VIN was not available.

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.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving approximately 15 mph uphill in the mountains, the transmission started slipping, followed by a loud banging sound. The contact stated that later, while fishing, there was an abnormal metallic sound like bbs hitting a tin can coming from the vehicle. The contact stated that previously, while driving at an undisclosed speed, the vehicle lunged forward, followed by grinding and banging sounds. There was no indication of a fluid leak coming from the vehicle. The contact stated that shortly afterwards, the vehicle stalled. The vehicle was restarted and resumed normal operation. No warning lights were illuminated. An unrelated warning light for the oxygen sensor was illuminated. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and informed that there was no recall coverage or assistance available for the vehicle. The manufacturer referred the owner to the NHTSA hotline for assistance. The failure mileage was approximately 181,000.

While traveling out of town on the highway,we had a sudden loss of power. My vehicle wouldn’t accelerate or shift. My check engine light came on and a message displayed that said something about reduced power. After limping to a dealership while in another city, I managed to wait hours for my husband to pick me and my children up. We waited several days for the dealership to tell us it was the valve body that needed replaced. My vehicle was not in the original recall for the valve body, although we experienced the exact same issues that the recalled vehicles experienced. This entire experience was horrifying. Along a stretch of highway that I was unfamiliar with, speed limits of 80mph, and a sudden, complete loss of motor power and speed, this could have someone. I had a vibration while staying at any constant speed for months prior to this, I had taken the vehicle in numerous times but was told the only thing to fix it was a software repair and that wouldn’t take care of the problem entirely. This vibration was and still is so bad that my phone will fall from the magnetic mount if I don’t let off the accelerator or increase acceleration. My vehicle still doesn’t seem to run properly but I am unable to get it to reproduce any issues when at the dealership. Extremely unnerving to travel with my family out of town or state and wonder if my fairly new vehicle will make it.

Rear wheels suddenly lock up momentarily during downshift at 30-50 mph (most reproducible 35-40). Transmission in a high gear (8th-10th); any throttle input commanding a downshift can trigger as the downshift executes, rear wheels briefly stop, skid with an audible chirp, vehicle jerks violently. Reproducible on demand, multiple times per drive, on video. Highest-speed event ~50 mph, family aboard. No advance warning: no check engine light, no message, no stored code, no gradual onset. Traction control sometimes activates at the instant of the skid, sometimes not — always reacting to traction already lost, never before. A driver has no opportunity to anticipate or react. This is a loss-of-control hazard. It is especially dangerous in a turn, on wet pavement, or in traffic. Onset may 2026. Pursued repair since, across three shops: an independent, twice (no codes/leaks/abnormal findings; maf replaced; unresolved; referred to dealer), then a gm dealer 3 days (test drove 34+ miles, no codes, fluid good, all shifts correct; declined recommended control-module recalibration, cause unconfirmed). Lockup recurred within 5 miles of leaving, same day; I returned immediately, asked for a tech ride-along while fresh — did not occur. Next day, a second gm dealer: tech note said fluid was low, though the same ro's inspection passed that fluid and found no leak; no leak ever identified anywhere. Paid $672 for a fluid exchange — unresolved. Days later, same dealer measured 265f on a 30-mile road test and condemned the transmission. Full replacement underway, largely out of pocket. Symptom matches recall 26v-085 (momentary rear wheel lockup, worn control valve, 10-speed/etrs) covering 2022 models. My 2023 is not included. I am not asserting a diagnosis — no one has established the cause — but I ask odi to consider whether that campaign should include additional model years. The failed transmission is available for inspection; videos available on request.

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.
