Incident: Twice our Chevrolet Silverado 2020 Duramax has experienced while operating, sudden with no warning "reduced engine power" and "check engine light" the engine sounds very different and does not operate as it should and presents a safety issue when you are driving and traveling at a high rate of speed. These incidences occurred on 10-4-2026 and 10-23-2026. The vehicle experienced a sudden failure of the engine coolant control valve, triggering Diagnostic Trouble Code P1006. This component failure restricts proper engine thermal management and poses a risk of sudden engine overheating while driving. General Motors has formally acknowledged this identical part failure as a chronic manufacturing and safety defect via Special Coverage Bulletins N252508341 and N252508340, which extend warranty coverage to 15 years/150,000 miles. However, GM has arbitrarily excluded the 2020 model year from this coverage, despite the vehicle utilizing the exact same defective part assembly number as the covered 2021-2023 models. This identical component failure across model years constitutes an unaddressed defect pool that requires immediate regulatory expansion to protect consumers from unsafe engine component failure. please fix this situation TY

Truck would not start - it left me stranded. The main body to engine ground strap had rotted off. I found there is a Chevrolet Customer Satisfaction Program (N252515590) for ground straps rotting for the same make/model/year as my vehicle, but for some reason mine isn’t listed by VIN number in the program.

It said on the dash, "Brake System Failure 43MPH Top Speed," "Service ESC," and lights on were the ABS light, BRAKE light, Engine Light, and Wheel Traction light. My wife and my [XXX] son's safety were at risk while driving on a busy 75mph highway and trying to turn around and make it home as the brakes did not work and having to cross busy streets. It was not able to reproduce but my local mechanic found the bulletin from way back that had not been addressed by GM after numerous times to a dealer for other repairs. I then took it to a local GM dealer that confirmed software update was not applied and they did the repair and I was charged to pay even though this was a known GM issue that never contacted me about this potential fatal random occurrence that could happen after I have taken great care of this truck. There not any warnings before randomly losing power on the highway once she hit 60mph on the on ramp and just started failing slowly.

We were traveling at approximately 65 miles per hour while towing our Coachmen Apex travel trailer with our 2020 Chevrolet Silverado 1500 LT equipped with the 3.0L Duramax diesel engine. During travel, we heard a loud popping sound originating from beneath the hood. There were no warning/engine lights or smell. Immediately afterward, we observed substantial smoke billowing from the front of the vehicle.We pulled off the highway as quickly as possible. Smoke began entering the passenger compartment through the ventilation system, and we observed flames beneath the hood. Recognizing the immediate danger, we evacuated the vehicle and removed our dog. We attempted to extinguish the fire using a fire extinguisher; however, our efforts were unsuccessful. The fire spread rapidly, and within minutes, the truck became fully engulfed in flames. The speed and severity of the fire left us with very little time to escape. We are fortunate that we were able to get ourselves and our dog out of the vehicle. This was a frightening and traumatic experience that placed our lives at serious risk while traveling on a major interstate highway. The incident also raises serious concerns about the safety of this vehicle and the potential danger posed to its occupants, other motorists, and anyone traveling nearby. We purchased and meticulously maintained this vehicle with the reasonable expectation that it would provide safe, reliable transportation. Instead, our 2020 Chevrolet Silverado 1500 LT experienced a catastrophic fire while traveling at highway speeds and towing our travel trailer, resulting in the complete destruction of the vehicle. Although we were able to escape, this incident could have resulted in serious injuries or fatalities. The rapid progression of the fire, combined with smoke entering the passenger compartment, raises significant concerns about vehicle safety and the time available for occupants to escape.

1. Transmission Issue: Since purchasing the vehicle, I have experienced ongoing transmission problems. The transmission exhibits noticeable shifting issues, including delayed response, harsh/rough gear engagement, and erratic shifting behavior while driving. 2. Intermittent Electrical & Sound Failure: In addition to the transmission issue, the vehicle has developed a severe intermittent electrical malfunction. Without warning, all audio and electronic sounds in the cabin completely turn off ("go mute"). This includes the loss of interior warning chimes, system alerts, and the audible turn signal clicker. The system restores itself randomly ("goes back when it wants to"), making the issue unpredictable. Safety Concern: The sudden loss of audible turn signals and safety warning chimes presents a driver distraction and safety hazard while operating the vehicle on public roads.

What failed: The automatic transmission on my 2020 Chevrolet Silverado 1500 Custom 4WD, 2.7L turbo (VIN [XXX]). It has an intermittent shudder, a stuttering vibration felt through the truck, under light throttle and under load. The truck is in my possession and available for inspection on request.…
What failed: The automatic transmission on my 2020 Chevrolet Silverado 1500 Custom 4WD, 2.7L turbo (VIN [XXX]). It has an intermittent shudder, a stuttering vibration felt through the truck, under light throttle and under load. The truck is in my possession and available for inspection on request. Safety risk: The shudder happens during acceleration and under load, when smooth power delivery matters most, such as merging or climbing grades. I tow a 20-foot camper in the summer, which puts the transmission under heavy load, and a driveline problem while towing raises the risk. No crash or injury has occurred. Confirmed by a dealer: Yes. On XXX, at 44,934 miles, Serra Chevrolet in [XXX] confirmed the transmission concern under GM service bulletin 20-NA-142, which the dealer confirmed applies to my VIN (repair order XXX). The technician performed a transmission fluid exchange as the recommended repair. I will update this report if the shudder returns. The technician confirmed the contaminated fluid from the factory. Manufacturer or others: The dealer submitted a goodwill request to GM, which GM declined, so I paid for the diagnosis and repair myself. No police or insurance inspection, since there was no incident. Warning lamps and symptoms: No transmission warning lamps or messages appeared. The only symptom was the shudder itself, which first appeared around XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

GM Corporate Legal has formally denied a repair for a known design flaw (TSB 18-NA-383) that has caused progressive structural corrosion and water intrusion underneath the cab carpets near vehicle electrical routing since 2024. The certified GM technician explicitly identified GM Technical Service Bulletin #18-NA-383 as the governing bulletin for this exact issue. The technician’s diagnostic notes state word-for-word: "...i inspected the truck and the rear window is leaking i can see water stains on the window and the head liner has a big water stain. the floor is not rotted out but the rear of the rockers and the cab corners are rotting and bubbling under the paint." This proves the structural rot is being caused from the inside out by a factory defect, not environmental road salt. I have a duplicate large packet that I sent including +15 dated photos to GM corporate/legal back in August.

I received a notice via OnStar of a P129 code of a critical issue with engine or transmission system on my 2020 Silverado pickup after I pulled on to the highway. Vehicle reduced engine power warning and engine light came on. I was forced to put vehicle in neutral and restart vehicle several times. This code indicates fuel pump control module being defective. After researching, there seems to be issues with this on the the following; General Motors has issued voluntary emission recalls (such as bulletins N252516900 and N262558690) for the fuel pump power control module on select 2021–2023 Buick, Cadillac, Chevrolet, and GMC vehicles. The issue with my vehicle is the same.

My transmission was shuttering from about 10,000 miles to 67,000. I reported it multiple times to the dealership and they did nothing about it until the 67,000 mark when they finally replaced it. the new transmission started to downshift very hard as soon as I got it back from the dealer and it just got worse I took it back and they had diagnosed that it was bad. They are in the process of replacing the transmission, a second time which would be my third transmission They’ve had my truck for 36 days. Clearly, General Motors and the dealership cannot figure out how to get my transmission to work properly. It’s a danger to my family and those on the road if it fails while on the highway.

I was driving down the highway doing 70mph when my check engine light started flashing. I had to pull over and turn off my truck and turn it back on in order for it to go away. I brought it to the dealership and they explained that I had a misfire on the entire driver side of the engine and I would need to replace it. I have kept up on all of my vehicle maintenance but it still requires a new engine, costing $11,000 if not covered under warranty. This is a known problem with the Chevrolet 6.2L V8 engine and is now a class action lawsuit with the company.

The failed components are available for inspection upon request. How was your safety or the safety of others put at risk? The A/C failure causes the driver's side to blow warm air, creating severe window fogging and reducing visibility in extreme weather, while the electrical/battery failure compromises vehicle operation and safety features. Has the problem been reproduced or confirmed by a dealer or independent service center? The A/C issue matches General Motors Technical Service Bulletin PIT5767A, caused by an internally bypassing condenser due to a mispositioned block-off plate. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has not yet been officially inspected by a manufacturer representative, but the defect aligns with known GM manufacturing specifications under bulletin PIT5767A. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Symptoms appeared suddenly with the air conditioning losing performance (driver's side blowing significantly warmer than the passenger side) alongside concurrent battery and electrical system failures.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).

- Air Bag Malfunction
On April 9, 2021, the Office of Defects Investigations (ODI) opened PE21-010 to investigate instances of air bag malfunction indicator light (MIL) illumination and potential for frontal air bag non-deployment in several vehicles manufactured by General Motors (GM). The vehicles included model year (MY) 2020 through…
On April 9, 2021, the Office of Defects Investigations (ODI) opened PE21-010 to investigate instances of air bag malfunction indicator light (MIL) illumination and potential for frontal air bag non-deployment in several vehicles manufactured by General Motors (GM). The vehicles included model year (MY) 2020 through 2021 CT4 and CT5 passenger cars, Sierra and Silverado trucks (1500/2500/3500 models), XT4 and MY 2021 Escalade, Suburban, Tahoe, Yukon SUVs.Technical Service Bulletin (TSB) 21-NA-005, issued in March 2021, addresses air bag MIL illumination with diagnostic trouble codes (DTCs) B0001-1B or B0012-0D. It cites rust particles in the connection terminal interface of the driver air bag inflator housing as the cause of the air bag MIL illumination. Illumination of the air bag MIL under these circumstances may result in a non-deployment of the frontal driver air bag during a frontal collision and increased risk of injury to the driver.GM stated a correlation exists between production delays due to the pandemic shutdown and premature corrosion initiation on the surface of the air bag inflator housing, which, in some cases, caused rust development during a seven (7) month period of vehicle production. In the rare instance when a rust particle dislodges from the driver air bag inflator housing and enters the air bag connector prior to assembly, an intermittent resistance spike at the air bag connector may result. The condition generates excessive resistance in the air bag electrical system when the steering wheel horn cover is manipulated or the steering wheel is turned. This excessive resistance is momentary. A crash commanding air bag deployment would need to occur exactly when the momentary excessive resistance occurs. Thus, there is a very low likelihood the hazard will present a risk during a crash of sufficient severity to warrant a commanded deployment. This failure mechanism occurs early in life and results in an air bag MIL illumination that corresponds to a DTC warning the driver that the vehicle requires service. The vehicle's air bag remains functional while the MIL is illuminated, and the DTC is present.Once the connection of the driver air bag module to the clockspring is made at the plant, or at the dealership for service, there is no longer an opportunity for rust migration into the connection point. The connector is sealed and has gold terminals, eliminating the expectation of fretting corrosion. All subject vehicles passed standard corrosion validation testing for extensive corrosion with no issue of air bag non-deployment.There is a low rate of occurrence: 1.41 incidents per thousand vehicles (IPTV) for all related occurrences, and 0.04 IPTV for occurrences with a mention of visible rust and/or corrosion on the air bag inflator housing. The average occurrence mileage for the subject vehicles is approximately 2,100. Every occurrence related to the alleged defect experienced an air bag MIL illumination and there are no verified allegations of air bag non-deployment within all data sources.To date, there have been no reported fires, crashes, injuries, or fatalities related to this issue. In view of the low rate, and the nature of early-life failure, the high detectability of failures, and low potential hazard to drivers, this Preliminary Evaluation (PE) is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.Review the ODI reports cited above at nhtsa.gov under the following identification numbers: 11537927, 11528888, 11525020, 11521401, 11506057, 11493107, 11486767, 11441525, 11433146, 11425658, 11423440, 11385267, 11376429, 11373466, 11366995.
