I had the 6. 2 engine replaced at 38k miles. Now at 78k miles my new engine replacement is using 1. 5qrt of oil within 4k miles. I am being told I have to watch the oil every 800 miles and report back to Chevrolet. I feel my investment is completely a loss of $60,000. 00 + . I was told by the service tech that I will probaly have to have another engine replaced again. . My resale value is no where near worth anything and I am stuck.

I am submitting this formal statement regarding a severe, recurring safety hazard involving sudden engine stalling and internal mechanical noise on my 2026 Chevrolet Silverado 1500. The vehicle has experienced multiple sudden engine stalls during low-speed deceleration, specifically while letting off the accelerator pedal to execute low-speed turns into parking lots. When the stall occurs, the engine dies completely, causing an immediate and dangerous loss of power steering and power braking assistance mid-turn. Because the vehicle shuts off completely while still in motion, I am forced to bring the truck to a dead stop, shift the transmission out of drive and into park, and completely cycle the ignition system to restart the engine. There is a distinct, audible mechanical ticking sound coming from the engine compartment during operation. Crucially, the vehicle has never illuminated a check engine light, displayed a dashboard warning message, or given any advance electronic indication prior to or during these sudden stalling events. This vehicle's build window falls directly into the scope of the national highway traffic safety administration’s (NHTSA) active engineering analysis (ea26005) investigating catastrophic valvetrain and engine failures on gm 6. 2l l87 engines. Because this defect causes an unexpected loss of vehicle control with zero diagnostic warnings, it poses an immediate highway safety risk to myself and others. I request a full diagnostic scan for hidden or pending fault codes, a physical inspection of the valvetrain/dynamic fuel management (dfm) system, and an inspection of the engine oil filter for metallic debris indicative of internal bearing degradation.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that the infotainment center intermittently went black, and there was water leaking into the vehicle through the top and lower center of the front windshield and the rear windshield. The vehicle was taken to a dealer, where the rear windshield was replaced without a diagnostic being performed; however, the failures persisted. Additionally, the side view mirrors intermittently failed to unfold when starting the vehicle. The contact stated that while driving approximately 40 mph, white smoke emitted from the exhaust, the vehicle hesitated, and it lost power. The check engine warning light illuminated, along with "service electronic stability control", "trailer brake system", "steering assist reduced", "service brake assist", and "brake system failure" messages, and the vehicle failed to exceed 40 mph. The vehicle was towed to a second dealer, arcadia Chevrolet Buick (210 s brevard Ave, arcadia, FL 34266), where it was diagnosed that the lifter and torque converter had failed. The lifter and torque converter were replaced, and the system was flushed. Approximately 800 miles later, the engine failed again. The vehicle was towed to an independent mechanic, who diagnosed that the torque converter and transmission had fractured. The torque converter and transmission were replaced; however, the warning lights and messages illuminated again, and the vehicle continued to hesitate when driven over 42 mph. After being parked for a few days, the warning lights were no longer illuminated and the mirrors opened, but the engine hesitation persisted. The vehicle was not further diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 10,000.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving at 55-65 mph, a rattling sound was heard coming from the front passenger-side of the vehicle. No warning light illuminated; however, the contact noticed that the voltage levels were between 9 and 11 volts. The vehicle was taken to the dealer, where it was diagnosed that the transmission had failed and needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure and filed a case. The failure mileage was approximately 79,000.

While driving on the road, the transmission in my truck completly neutralized all the gears (meaning it just started revving and slowing down rapidly in the middle of the road with cars in front of and behind me). And almost got me hit by several cars. I got the vehicle towed to the chevy dealership it was bought from. The mechanics then confirmed the code was for a failed valve body in the trucks transmission. Which they had recalled in all the diesels but not gas engines.

My truck suddenly stopped, received a message on the dashboard that said transmission hot. Idle engine. I was unable to remove my key. Minutes later it started up like nothing.

This vehicle is a 2024 Chevrolet Silverado 1500 featuring a 6. 2l v8 engine and a 10 speed transmission, currently at 58,136 miles. The vehicle was experiencing a severe shudder. An official gm technical assistance case (tac) engineering case was opened on July 30, 2026 confirming a verified dfm cylinder deactivation or valve train malfunction. However, on August 21, 2026 the dealership falsified the repair log by printing ‘concern not duplicated’ to the manufacturer, while physically installing an unapproved aftermarket range technology dfm eliminator module into the vehicle’s engine harness to artificially override the factory emissions and cylinder deactivation programming to mask the mechanical failure. This vehicle is part of the active NHTSA engineer analysis ea26005, and the manufacturer’s dealer network is actively using unapproved third party hardware shortcuts to evade mandatory warranty repairs before the vehicle’s 60,000 mile factory powertrain limit expires. I called gm to report and request a warranty freeze and regional field engineer to go to a different dealership and was told they can’t freeze a warranty because the tac was closed on August 28, 2026 as resolved even though it was not resolved.

"the transmission valve body is failing, causing the rear wheels to violently lock up while driving.

Shuddering at 25 to 50 mph, harsh shifts, hesitation.

My husband was driving his 2021 chevy trailboss when it went into limp mode. It had to be towed to the dealership and it was uncovered that his truck was throwing out codes p0700 p2732 which is a known issue with this truck, resulting in internal valve body hydraulic failure. Since his vehicle is at 70k miles, and over the 60k, the dealer is pushing back and trying to say they don’t have to cover it. Gm states that we should pay and then submit a reimbursement form. This is a $3800 fix. This is not our responsibility and this is unsafe. This should be a safety recall for all vehicles of this make, model, and with this transmission. Additionally, he had to have his engine replaced on this truck (we bought it brand new in 2021) with only 10k miles on it. This truck should not be built anymore and anybody facing these issues should not be held liable for them. This is a manufacturing issue and it is only one company’s fault, general motors!.

45,000 mile 2022 chevy Silverado 1500 lt - vehicle began rough shifting, slipping gears, failing to engage into drive, and shuddering at constant acceleration. Transmission valve body failure and replacement needed - confirmed by certified chevy dealer. Awaiting receipt of warranty valve body from gm, but part has not been released by gm - estimate from dealer is 5+ weeks for receipt of the part based on recent experience with another customer requiring the same repair.

I own a 2022 Chevrolet Silverado 1500 that is jumping and jolting. There is currently a federal recall and the dealership is denying to fix it for free under recall because our VIN is not yet listed, despite the vehicle suffering from the exact transmission failure reported for the same year, make and model. This matches the exact parameters of safety recall n252516560. The vehicle is unsafe to drive.

Transmission failed at 38,000 miles. Downshifted violently while driving and couldn't keep up with the 35mph speed limit. Was luckily not on a highway or far from home. Dealership noted it's a common valve body issue in the transmission. No inspections, vehicle has a branded title (hail) and chevy claims no responsibility for the transmission failure. 0 warning signs or issues.

The contact owns a 2016 Chevrolet Silverado 1500. The contact stated that while attempting to make a left turn from a complete stop, the vehicle lost motive power while depressing the accelerator pedal and was stranded in the middle of traffic. No warning lights illuminated. The vehicle was placed in neutral(n) and pushed to the shoulder of the road. The contact's husband arrived at the scene and restarted the vehicle; however, while driving at low speeds, the failure recurred. The vehicle was towed to a dealer, where it was diagnosed with metal shavings in the transmission. The dealer informed the contact that the transmission needed to be replaced. The vehicle was not repaired due to the repair costs. The check engine warning light illuminated. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

I just purchased this vehicle on xxx and on xxx, with less than 300 miles on it, we were in a parking garage at the galleria mall in [xxx]. While driving slowly uphill in the garage looking for a parking space, the vehicle suddenly went into neutral and the engine shutoff. After verifying all was well, I restarted the truck and continued to drive. It happened two more times with the same situation, low speed going uphill. I have not taken it to a chevy dealer yet for diagnostic as there were no lights like the check engine light and no codes presented. My onstar app reports that all is well and no issues, so I know it will not be something they can find when they try to pull the codes. I did a search on the internet for this issue and found others with the same problem, no known fix, and in one case the person was able to return the truck and they purchased a different truck from a different manufacturer. That gentleman said he did try to work with gm at the regional level with a service rep. He said something is causing the voltage to drop in lower gears, causing it to invoke a safety feature to stop the vehicle by going into neutral and shutting off the engine. On an incline, with no engine, the brakes become very hard to push and the vehicle could roll back. In a parking garage, that could mean rolling back into a person or another car. When it happens there are in internal codes that do not show up, but are wiped when you re-start. There are threads on reddit and in facebook groups that discuss this issue as well for further evidence. My purpose is to get this documented outside of gm, it seems like a niche problem, but one that could be dangerous in the right circumstances.

Had the motor replaced under recall / warranty at a certified chevy dealer. ~41k miles. 6. 2l l87. Graff chevy of chesterton indiana. After long lead times and getting the run around, the truck was "done". Picked it up and many things were still wrong/incorrect. They were able to take care of it. A day later, the truck died in the road. Towed to another graff dealer. 2 days later it was found to be a bad ground. Fixed. Fast forward ~3k miles later. The transmission went out and locked up on a main roadway. Towed to another dealer (west herr chevy orchard park NY). They found the root cause was due to transmission cooler lines coming loose from faulty installation during motor swap. There were also many other items found that were broken or loose under the hood of the vehicle from faulty workmanship. I am being told it is not covered under warranty because of the previous dealer's workmanship (graff indiana) I was able to get the truck put of the roadway and to a safe place, but this very well could've caused an accident, and I would like to document it.

I have a 2022 silverado ltd with the 6. 2. I purchased the truck about a month and a half ago the previous owner had the 40 weight oil recall completed prior to my purchase. I had the oil changed when it said 45 percent life remaining far before it was due a certified chevy dealer completed the oil change with the 40 weight correct oil. Well about 8 days ago I went out and started the truck and heard a clunk sound like a failing starter would make. So later that day I notice a ticking noise as well as a chirping noise. Coming from engine bay. I made note of it. Ever since the noise began I have kept close eyes on it the ticking and chirping rise and fall when I give it gas. Yesterday when I started it the clunk noise happened but this time I felt a shudder or stutter I looked at the rpms and they didn't move at all with the shudder. I have an appointment Monday morning to take it to the dealer I looked into the recall for the thicker oil. And learned that this motor is pretty much junk and multiple issues I haven't driven it since yesterday because the issues I'm having correspond with complete engine failure at any point and I do not want to be on the highway and it happen that would put me and other motorist at risk injury. There has been no warning lights no engine light just the initial clunk the first time and since that it's just been getting worse.

My truck has been shuttering when accelerating and hard shifts periodically. The engine is also tapping. I have right at 74000 miles. Regular oil changes and maintenances.

I was driving my 2019 chevy silverado trailboss with 81,000 miles at 65mph on I-80 east in omaha, ne, when 3 warning lights came on. The first was the service parking brake. The second was service esc. The final was a flashing check engine light. My truck started backfiring/misfiring, making a loud ticking noise, and running extremely rough. I was trying to merge off the interstate, but it was running so rough that it made it very difficult to do so safely. Eventually, I just had to finish going where I was headed and park it in the lot. I did some research and called my local shop. They said to stop driving immediately and have it towed to them for inspection. They used a diagnostic tool and diagnosed the issue as a dfm lifter failure. But they could not fix it there and recommended I take it to a different shop. I had it towed again, and they did their own diagnostics and have the same idea, but without taking the engine completely apart, they can't tell for sure. They want to charge me $1,250. 00 to inspect it further. I called the dealer where I purchased the truck back in 2019 and am working with them on next steps. The last shop quoted me $7,800 repair if it is indeed the dfm lifters. Based on what I know, this is a known issue with these trucks. Gm has an "out of warranty policy assistance" in place just for these know lifter issues. This is very concerning that gm hasn't done a recall on these parts as it has shown to be a safety issue when driving the vehicle in traffic on the interstate. I just hope that gm assists me with the repair costs because it is not guaranteed and I cannot afford $7,800 right now.

Vehicle bucks upon acceleration in the rear end. Dealer recommends replacing the transmission.

Third transmission failure in 10 months on this vehicle (8-speed automatic). (1) oct 2025, 67,885 miles: transmission shuddering; dealer replaced the complete transmission with a gm remanufactured unit under extended warranty (ro 240481, nucar lannan Chevrolet of woburn, MA). (2) Jul 2026, 82,439 miles: vehicle would not shift on the highway while driving; dtc p2824 stored; dealer replaced the transmission valve body under warranty (ro 248929). (3) Aug 3, 2026, approx. 82,500 miles — three days after the valve body repair was returned to me — the transmission locked up and the vehicle would not shift gears while in traffic. Loss of gear engagement while driving creates risk of a crash from sudden loss of propulsion. Vehicle is back at the dealership now for the third repair. This vehicle's 8-speed transmission (8l90/8l45 family) is the subject of known shudder/valve-body defect litigation covering 2015–2019 silverado models.

In reference to 2024 Chevrolet pickup, 6. 2l engine, 10 speed transmission. The vehicle is available for inspection upon request. I believe the transmission is going into "partial lock-up" at full/highway speed. When traveling on highway with cruise control engaged, the vehicle suddenly acts as though the brakes are being strongly applied, slowing the vehicle at a very rapid rate, down as low as about 40 mph. The vehicle slows quickly enough that the driver and passengers are thrown forward to the extent allowed by the seat/safety belts. The issue terminates itself at various times. The vehicle has been inspected by gm mechanics several times, but they cannot find the problem. There were no warning lamps, messages, service engine lights, etc. This has occurred on at least five (5) different occasions. The first occasion was at approximately 7000 odometer miles. The vehicle now has 25,100 miles. All incidents have been reported to gm dealership mechanics.

Vehicle: 2020 Chevrolet Silverado 1500 4x4 lt (5. 3l v8 engine) component: engine (piston rings, lifters, and motor assembly) / powertrain component availability: yes, the failed components/vehicle are available for inspection upon request. What happened and safety risk: while operating the vehicle on prince street in clovis, nm, the engine suddenly began knocking violently without any prior warning or symptoms. Immediately following the mechanical failure, dashboard warning lights illuminated (including the check engine light, abs, and traction control) and the vehicle dropped into "reduced engine power" mode. This caused an immediate and hazardous loss of acceleration on an active roadway, forcing an emergency maneuver to navigate out of traffic and pull over safely. This sudden powertrain failure poses an unreasonable and severe safety risk to the driver and surrounding traffic. Confirmation and inspections: the mechanical failure has been confirmed and diagnosed by hamilton chevy in portales, new mexico, and sanders repair services in portales, new mexico. The vehicle and components have not been inspected by the manufacturer, police, or insurance representatives. There were no warning lamps, messages, or symptoms of any kind prior to the sudden failure.

Hard shifting, shuddering, clunking sound when shifting between drive and reverse. Was informed by ken ganley chevy in brookpark , ohio that the valve body inside the 8speed transmission is faulty and is on a nationwide backorder.

2021 chevy silverado 5. 3 trail boss lifters has failed on this driver two times while driving on highway engine lost power with my family in the vehicle. Dealer warranty fixed lifter the first time lifter went out at 1100 miles. The vehicle has failed again with multiple lifters going out and camshaft needing being replaced also on my extended warranty at 73000 miles. I do not want to take this vehicle back in my possession as it has put me and my family at risk twice being stuck on highway with no power.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving approximately 30 - 60 mph, the transmission failed to shift properly, and the vehicle hesitated while depressing the accelerator pedal. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and the contact was informed that the valve body needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA hotline to report the failure. The approximate failure mileage was 105,000.

I have been having issues with my vehicle for the last 1,000 miles or so where it appears to be losing power while accelerating normally, I'm not sure if the issue lies with the engine or powertrain/transmission. I took to dealer last week and they were unable to reproduce. The issues have been getting more frequent and intially were only occuring after the vehicle warmed up, now it has started while vehicle is cold. Feels like the power drops (rpms drop) during a normal acceleration. As of 7/16 I now have a check engine light on, onstar indicates an issue with my engine, transmission, electrical. This is putting myself at safety risk along with others as during my normal drive the engine is losing power and could either leave me stranded or cause an accident.

Transmission needs to be replaced at 77000 miles!! a known problem with this make/model/year and nothing is being done!!!!!!!!!!!!!!!!.

About 2 months after bringing the truck in for the engine recall, my oil cooler blew up and I required that to be replaced, along with the radiator and hoses.

July 11, 2026 I experienced a lifter failure. Towed to gm dealer on July 13th. Dealer comfirmed lifter failure and camshaft damage and metal contamination throughout engine. Dealer installed replacement engine using my mechanical breakdown policy since I was out of factory warranty. Picked up truck one month later with new engine and the transmission started slipping and shuttering. Took back to dealer who claimed metal fragments in fluid and said transmission needed to be replaced. I then made a second claim on my mechanical breakdown policy and the dealer replaced the transmission. All of these issues are known issues with the engine and transmission.

On xxx I was driving from [xxx] to my sister's house in [xxx]. I was relocating to [xxx] for a job. I was pulling a u-haul trailer (6x12) that contained significantly less weight than the truck can handle. About halfway there, on back roads, the truck suddenly slowed significantly and the gas pedal was unresponsive. The light in the dashboard read reduced acceleration - drive with caution. Pulled over, turned off truck, opened driver side door, to reset the truck (read this on google). We had to do this a couple times, because it would just go back to that behavior after a bit. We made it to my sister's house to stay the night. In the morning, xxx, I called the local chevy service dept in [xxx] and asked if I could bring it in, I described the problem. During the drive to the shop, the same issue occurred. Upon arriving at the service dept, the trailer app was giving a warning that the load may be heavier than max. Which cannot be true. The dealer techs said they had never seen anything like it before, but they seemed to know what to look for. They then informed me that they could not loan me a car because I was traveling out of state. I had a deadline, so my only option was to rent a u haul box truck, unload the back of my truck into it, hitch the trailer I already had to it, and drive to [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
