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.

I am filing this safety complaint regarding the sudden and unexpected transmission failure of my 2023 Chevrolet Tahoe at approximately 110,000 miles. My transmission failed without any warning, creating a serious and frightening safety concern. There was no advance indication that I was about to experience a major mechanical failure. A transmission failing unexpectedly creates the potential for an extremely dangerous situation, particularly when traveling at highway speeds, navigating intersections or driving in heavy traffic. I purchased this vehicle brand new and have consistently had it serviced at bergstrom Chevrolet of madison. My maintenance history includes approximately 20 dealership visits between January 2023 and July 2026. Despite this extensive service history, the transmission failed less than four years after I purchased the vehicle. I am extremely concerned that such a critical component could fail without warning. An unexpected transmission failure can put the driver, passengers and surrounding motorists at risk, particularly if the vehicle suddenly loses its ability to accelerate or maintain speed. The Chevrolet dealership diagnosed the transmission failure and provided an estimate of approximately $7,500 for replacement. I contacted general motors to report the failure and request assistance. Gm denied my request solely because the vehicle had exceeded its warranty mileage. When I asked whether the decision could be appealed, I was told no appeal was available. My primary concern is the safety implications of this unexpected failure. I believe this incident warrants investigation to determine whether other owners of 2023 Chevrolet Tahoes may be at risk of experiencing similar transmission failures without warning. I am requesting that NHTSA review this incident and determine whether a potential transmission safety defect exists.

Vehicle began making loud knocking sound xxx towed to dealer 9/8 after holiday. They found metal in the oil and believe it needs an engine replacement. A week later I have no answers, there's no loaners available, so I am just without a car. We bought car from zimbrick chevy in [xxx]. It was never disclosed to us that the vehicle had an engine replacement right before we purchased. New engine lasted about 16,000 miles. Only once we saw the history of the car in the current dealership's service app did we learn about the engine replacement. This is beyond unacceptable! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On September 5, 2026, at approximately 7:18 p. M. Pacific time, a 2025 Chevrolet Tahoe high country equipped with the 6. 2l l87 v8 engine and approximately 18,000 miles experienced a sudden catastrophic failure while the engine was running. There were two occupants. A distinct pop was heard. The engine immediately lost power and multiple dashboard warning lights/messages began flashing. Within approximately 20-30 seconds, smoke and an electrical-burning odor were noticed. The vehicle was shut off manually and both occupants exited. Flames were first observed toward the rear of the engine compartment. The fire spread extremely rapidly, and the vehicle was substantially engulfed within approximately two minutes and completely destroyed. The sudden loss of propulsion created a crash risk, and the rapid fire placed both occupants at risk of serious injury or death. No physical injuries were reported. The precise failed component and fire origin have not yet been determined. The vehicle had received an oil change from an independent service facility within approximately 30 days before the incident. The cause has not been confirmed by gm, a dealer, or an independent fire expert. The vehicle is involved in an active insurance total-loss claim; inspection should be coordinated promptly before the salvage is released, dismantled, sold, or destroyed. More than 100 photographs and several videos taken during and after the fire are available. A fire department report is pending. Because NHTSA engineering analysis ea26005 includes 2021-2026 gm vehicles equipped with the l87 engine and later-produced engines outside recall 25v-274, please associate this complaint with that investigation and evaluate whether an l87 engine failure initiated the fire.

Driving on the highway the engine failed at highway speeds and the Tahoe experienced a complete shutdown, we could not restart the vehicle nor shift to neutral. We had the vehicle towed and was told by the dealer that it needs a engine replacement at 14,000 miles.

Our Tahoe keeps burning through oil. About 2/3 of the way through an oil changes I have to add 2 more quarts to get to the next oil change. Our Tahoe was not part of the initial recall I am not sure why.

Water pump failed. The part is on back order with an eta of October 29. Vehicle is currently at the dealership. I received no alerts before failure.

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 vehicle had a pop and loss of power on the highway. After pulling over, I did not have a check engine light but did connect my code reader and found a p308. I felt unsafe to drive so I had it towed to a shop. I later found out the dod system or lifter on valve #8 has failed and needs replacement. Factory recommends oil change at every 7k miles, I did them at 4k. My oil pressure was up to par with the small window of real time allowable oil pressure. The design was great on paper but one of the worst engines gm has ever made. I sincerely hope there is enough people complaining about these 2021 gm 6. 2 & 5. 3 engines!!.

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.

[xxx] diagnose on xxxx vehicle shudder dealer stated felt some tire vibration. Back to the dealer in August same issue. Tahoe shudder and misfiring first seen by [xxx] chevy of [xxx] on xxx stated it the dfm and its very pronounced. There is no correction that can be made to change this shudder. Xxx service transmission, not able to shift soon warning light came on while driving down the road multiple times. Dealership stated caused by low voltage charged battery and sent me on my way. Went back and gm had them to check battery over again and again and they finally replaced my battery. Xxx back in the shop at bentley Chevrolet florence al. Kept 2 weeks. Stated shudder is a normal operation from the gm tech. Also received a misfire code as it clearly is missing while at idle it almost acts as if its going to go dead at a red light. Tach case # xxxbentley tech stated that gm reviewed data their response was this is a normal operating condition. This vehicle has only 23,000 miles its a 2023 Tahoe z71 and still under the powertrain warranty, but they refuse to fix the misfire acting like its going to go dead at a red light.

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.

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!!.
