I took my truck in to have a bad fuel pump module looked at. During the inspection they found some metal in the oil and it was confirmed by more being in the oil filter. This truck had previoulsy been cleared on the NHTSA campaign 25v-274, but now it appears that it is a part of that recall. The dealer has initiated the work with the chevy corporate offices and I am working to secure a rental/ loaner car. I am filing this in the event there are any issues getting the new replacement engine.

2026 6. 2l engine loud and oil filter is filled with bearing glitter. I know you have recently opened an investigation into 2025 and 2026 gm 6. 2l engines also failing. The salesman lied and told me the issues were all fixed. How is a company allowed to lie and put my family at risk with a faulty engine. I am driving and engine that is shedding bearing material for 3 oil changes. This will fail and leave me stranded or create an accident. 1st oil change at 1500, second at 6000, 3rd at 10,500 and oil is full of bearing material. Pics attached.

Engine is the 6. 2l v8. Engine has started consuming oil. Consumed approximately 3 quarts of oil over 4k miles. 0 signs of external leakage.

My truck started skipping and over time the check engine light came on. I took it in and they are saying it is the lifters, which is costly. I know this truck was built during covid and I know a lot of the manufacturers were dealing with skeleton crews. I heard this was an issue with the 2021 silverado trucks, and a recall. Can you please advise?.

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving 45 mph, the vehicle lost automotive power. The vehicle was restarted within seconds and the message "push to start" was displayed. The vehicle was taken to the dealer to be diagnosed, and the contact was informed that the failure was not duplicated. The manufacturer was notified of the failure. The failure mileage was 30,000.

Statement for NHTSA subject: safety complaint – 2021 Chevrolet silverado unexpected jerking/harsh transmission engagement I am submitting this complaint regarding my 2021 Chevrolet Silverado 1500 2. 7l turbo with approximately 128,000 miles. My vehicle has developed a recurring problem involving harsh/jerking transmission engagement, hesitation, shuddering and abnormal shifting. The truck can jerk when engaging or changing gears and has also experienced a hard engagement when shifting from reverse into drive. During normal driving, the vehicle can hesitate or feel as though it is repeatedly fluttering/shifting instead of providing smooth and predictable acceleration. The vehicle has produced diagnostic trouble codes including p0700, u0100 and p0420. I am concerned that this condition could create a safety hazard, particularly if the vehicle unexpectedly jerks, hesitates or fails to respond normally when accelerating or changing gears in traffic. I am requesting that NHTSA document this complaint and review whether there is a pattern or potential safety-related defect involving transmission engagement, shifting or drivetrain control on 2021 Chevrolet silverado vehicles. Gm has published service information concerning delayed and harsh transmission engagement on certain silverado applications, including 2019–2021 models, which makes me concerned that my vehicle may be experiencing a related issue. I am retaining my repair records, diagnostic information, receipts, videos and mileage/date information documenting when the problem occurs. I am willing to provide this information if requested. Please help me get my truck corrected, I love my chevy truck. Thanks sincerely michael fields.

While driving this 2026 chevy silverado, the engine has shut off while driving it. While driving down the road the engine will shut off and a message on the display will show "return to neutral" and "press start". This is very dangerous to have a vehicle shut off while driving down the road as it affect my family and other drivers on the road. The vehicle need to be completely stopped to shift to park, in order to start the vehicle again. There are no signs or warnings that this is going to happen, it just happens randomly. The dealer can not reproduce the problem but did confirm to me this has happened to several other same make/model vehicle that have been reported at the same dealership. On another unrelated safety issue with this same vehicle, the gas tank over flows when filling it up. Dealer was able to reproduce this problem, but doesn't know how to fix it yet. Is waiting to gm to approve what should be replaced, under warranty. This is dangerous for me and other people at gas stations. I can't fill my vehicle up all the way with fuel, otherwise it runs down the side of the vehicle and on to the ground where it is very flammable.

Vehicle is hard shifting and has the following error codes. Engine p0700 transmission control moduel requested, test not passed transmission p0747 transmission control solenoid valve 1 stuck on- test failed. Warning indicator requested. Very concerned to be driving this vehicle.

We were sold a 2022 zr2 1500 chevy pickup on 8/14/2026. The dealer disclosed "unknown" on the used car buyer disclosure form. By admission of service department this truck's engine seized in March 2026. A replacement engine was ordered, placed on back order, and arrived to the dealership in August 2026. The service department believed that the repair was done and finished on 8/14/2026, the same date as the purchase. On 8/30/2026, the truck was not running properly, not moving forward despite pressing on the gas, and lots of instrument panel lights. The truck was towed to the dealership and "fixed" they claim it was a fuel injector and separate from the issue regarding the engine.

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 company had a complimentary repair of the known issue of bad oil cooler lines. It oblast short period. I now own the vehicle and it still has leaking oil cooler lines why should it not be replaced by gm since the lines leaking or coming apart and possibly blowing up and engine is a known problem. Would like gm to replace it under the program they already had offered.

Not that anything has happened to my truck but im genuinely worried that something bad will happen with my motor. With it being the 6. 2l l87 motor. My truck was manufactured July 2024 which is 2 months after gm's cut off. I love the truck but im worried about going to and from work, what if I was to turn and this truck dies and I go into oncoming traffic? what about everyone else driving their own vehicles? I hope something is done because im really thinking about getting rid of this truck in fear of something bad happening. Thank you.

Multiple instances of engine shutting off while driving and switches to "park". Most recently the truck suddenly lost power, shut off, stopped immediately, went into park, jerked extremely hard, and displayed the message “service transmission. ”.

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.

Took it to the dealer for the l87 recall back at the end of April 2026. Gm stated that my truck passed the inspection and “upgraded” my oil to the new 0w-40 oil. Now 8-27-2026, 6500miles after the inspection. Driving to work in the morning, and my engine failed. What I believe happened was a lifter got stuck and the engine shook and all lights on the dash were flashing. Vehicle is currently at the dealership and they are saying the “special” warranty does not cover this failure. Which to me is completely unacceptable. Because for 72,900 miles I never had an issue with the truck. But 6500 miles after they changed the oil to the thicker oil now I have an engine failure.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, all warning lights illuminated and the vehicle stalled. The contact stated that after several seconds, the vehicle was restarted and shifted into park(p). The vehicle was taken to a dealer to be diagnosed; however, the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 300.

My 2022 Chevrolet Silverado 1500 high country with the 6. 2l l87 engine suffered a sudden catastrophic engine failure after passing the inspection for recall 25v274 at approximately 70,000 miles and being returned to service. While I was pulling into my driveway, the engine abruptly shut off as though the ignition had been turned off. It would crank but would not restart. The sudden loss of propulsion while the vehicle was moving created a safety concern; a similar shutdown in traffic could cause a crash. The Chevrolet dealership disassembled the engine and documented multiple lifters stuck in their bores, requiring excessive force to remove, and deep cylinder-wall scoring that could catch a fingernail. The dealer determined that the block damage required complete engine replacement and replaced the engine. The dealer attributed the failure to lack of oil or improper maintenance and denied recall-related coverage, stating that the failure involved the upper engine rather than the crankshaft or connecting-rod bearings covered by the recall. I strongly dispute the poor-maintenance conclusion. Oil changes were performed regularly. The dealer told me the oil was somewhat low but still within the operating range when the truck arrived after the failure. I ask NHTSA to review this sudden engine failure following completion of recall 25v274 and whether the recall inspection/remedy adequately addresses the risk of subsequent engine failure. I am not asserting that a particular manufacturing defect caused this failure; the underlying cause remains disputed. Availability of the failed engine for further inspection is unknown.

The engine in my 2023 silverado zr2 (6. 2l l87 v8) failed. It is available for inspection at rick hendrick Chevrolet ([xxx]). On xxx at about 67,000 miles, and the days leading up to it, the truck repeatedly struggled to start due to metal on metal contact, almost leaving me and my family stranded multiple times. Driving the vehicle produced a loud rattling noise at 2200 to 2700 rpm, and felt unsafe to drive. Especially with my family. The problem was reproduced and confirmed to be an engine failure by the rick hendrick chevy dealership a week after being dropped off with an appointment. I have been told the engine needs to be replaced under the special coverage program (n252494003). The l87 recall inspection and oil change was completed on xxx also by rick hendrick chevy. There were not warning lights or other symptoms leading up to this engine failure. The symptoms of struggling to start and the ticking noise as 2200 to 2700 rpm started that weekend before I brought to dealership. They got progressively worse. Dealership has said I will receive a new engine under warranty but no timeline for completion. Additionally I have not been furnished with a service loaner or option for one. Leaving me with no vehicle to replace it. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My head, my transmission in my Silverado 1500 6 speed has had rough shifting since I bought it had 29,000 miles on it. It also has been looked at for the rough and they said it was normal now at 100,000 miles by train ships out of gear while driving and coming to an idle at random spots, took it into a train shop westland transmission. They said I need all new transmission which I think this should've been fixed a long time ago with the rough shifting the recall and lawsuit needs to add the six speed trans to the eight speed intense speed that gm is officially getting served on.

Dfm failure caused major engine damage and loss of power on interstate.

Coolant control valve is malfunctioning. Check engine code p1098, running fans loud cooling fans running at full blast shortly after turning off the engine. General motors issued special coverages n252508341 extending coolant control valve warranty protection up to 15 years or 150,000 miles for select 3. 0l duramax vehicles. Unfortunately, gm says my VIN isn’t covered by the extended warranty even though it has all the same issues as those that are covered down to the check engine code notes on their bulletin n252508341.

The contact's husband owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving approximately 35 mph, the check engine warning light illuminated but disappeared the following day. The contact stated that approximately four days later, after refueling the vehicle, while stopped at a red light and attempting to make a right turn, the vehicle stalled. The vehicle was pushed to the side of the road and towed to the residence. The vehicle was then towed to a dealer where it was diagnosed and determined that the fuel pump module needed to be replaced. The contact stated that dtc: p129f was retrieved. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 23,600.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving 55 mph, the vehicle suddenly began to shake, vibrate, and lose speed. An abnormal knocking sound was heard coming from the engine, and the check engine warning light illuminated. The vehicle was towed to the contact's residence, where the contact, a master mechanic, examined the vehicle. The contact diagnosed that the fuel management system, lifter springs, camshaft lifters, engine push rods, and rocker arms needed to be replaced. The vehicle was not repaired. The local dealer was notified of the failure and informed the contact that the VIN was not included in NHTSA campaign number: 25v274000 (engine and engine cooling). The contact stated that the vehicle experienced the same failure described in the recall. The manufacturer was not notified of the failure. The failure mileage was 11,450.

Truck started violently shaking while driving 70 mph on highway. Check engine light, service electric parking brake warning light, tcs/esc warning light, started flashing on tachometer. Check engine light remained on when truck was restarted later. Chevy dealer service department reproduced problem and found broken bits of metal in the oil filter. Engine is shot. Likely caused by truck's dynamic fuel management system. Dealer advises only option is to replace engine. Truck was up to date on all service maintenance.

I did the 0w-40 oil swap and now my truck is having more issues than before the recall, doing a “oil consumption test”.

Number 2 cylinder lifter failure. Metal found in oil. Need to replace the engine.

I purchased this vehicle brand new and have experienced a recurring issue when coming to a stop. The forward sensors activate indicating I am too close to an object (even though nothing is in front of the vehicle), and the engine stalls. Everything shuts off except the driver information screen, which displays the prompt "shift to neutral and press start again. " following this prompt does nothing; I have to shift into park and press the ignition again to restart the vehicle. I have taken the truck to the dealership multiple times. After the first two visits yielded no solution, the maintenance team contacted chevy engineering, and a hard reset was performed. However, today (8/24), a similar issue occurred. While at a complete stop with a full car length between my truck and the vehicle ahead, the sensor warnings activated. The engine did not stall as it had before, but the issue seemed entirely random.

Afm causing engine tick. I am reporting a radiator failure on my 2019 Chevrolet Silverado 1500 equipped with the 6. 2l v8. The vehicle developed an active coolant leak from the radiator assembly. The coolant reservoir level dropped significantly after normal driving, and coolant was visibly leaking and collecting underneath the vehicle. The truck initially began running warmer than normal, approximately 215–220°f, before the leak was fully identified. After topping the system with the correct dex-cool coolant, the coolant level continued to drop and an external leak became clearly visible. The vehicle was subsequently parked to avoid engine overheating or further damage. The original radiator carries gm part number 84152439. I have since been advised that the current gm replacement radiator is part number 85575815. I was also informed by gm dealership personnel that radiator failures involving this application are currently being investigated. My concern is that a sudden radiator failure can result in rapid coolant loss and overheating, potentially causing engine damage or vehicle disablement while driving. This is particularly concerning because the temperature gauge may initially remain near normal even while coolant is being lost. I am requesting that NHTSA review radiator failures on 2019 Chevrolet Silverado 1500 models, particularly vehicles equipped with the 6. 2l engine and heavy-duty/enhanced cooling package, to determine whether there is a pattern of premature radiator cracking, tank/seam failure, or other coolant-loss defects that warrant a safety investigation, service campaign, or recall.

This complaint is in relation to the investigation into the gm l87 (6. 2l engine) investigation. I own a 2024 Chevrolet silverado with the l87 engine. I had my truck inspected through the recall a few months ago and the engine passed at that time. The engine oil was changed by the dealer per the recall at that time. On August 23, 2026, I was traveling at highway speeds on an interstate highway when my truck began to lose power, downshifted hard three times and died in the middle of the highway. The truck shifted to nuetral and I was able to coast off the highway into a rest area. I attempted to start the struck but nothing happended. I had the truck towed to a dealer. They inspected it on August 25, 2026 and determined the engine had a catastrophic failure and needed to be replaced. I am currently waiting on a replacement engine.

My lifter failed in my chevy Silverado 1500 on the highway, causing severe shaking while driving and an array of dash lights. After taking it to a local. Chevy dealer, they confirmed a lifter collapse and possible damage to my cam shaft. I have been up to date on all oil changes with premium synthetic oil, and there were no prior dash lights indicating a problem.

Lifters are failing. Engine is making horrible engine noise. Mechanics said it was lifters.

Lifter and cam shaft failure rendering vehicle unable to run on the side of the road 5 hours from home.
