| Jan 2026 | POWER TRAIN | Vehicle was brought to Payne Chevrolet(Weslaco,Tx)for Recall N242454440. After the software update, the vehicle entered 'Limp Mode' and threw a Permanent Fault Code P2817 (Solenoid 8 Stuck Off). The dealership and GM Executive Resolution (Case #86918646) have confirmed this is a mechanical failure of the valve body, but are refusing/delaying the remedy due to a branded title. The vehicle is currently grounded and unsafe to drive as it risks rear-wheel lockup. GM has failed to provide a timely remedy or alternative safe transportation. | Crash: No Fire: No | Unknown |
| Jan 2026 | POWER TRAIN,ENGINE | The Timing Chain failed. It is at the Dealership available for inspection. Vehicle was unable to accelerate correctly while driving. If it had blown a valve or locked up the engine we would have been stuck on the highway with my kids in the vehicle. Problem has been confirmed with the dealer. It is a known defect with this vehicle but my VIN was not one that was recalled. No issues had came up before it failed. Just went to accelerate and you could feel it slipping and the truck stuttering forward. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM,SERVICE BRAKES | While driving home from work the truck displayed numerous trouble codes including ebc failure, braking failure, traction control failure and trailer brake failure as well as vehicle governed to 42 mph. I took it to the dealership and they checked all of the braking system and could not find any issues. They reset the codes, and changed all 4 pads and rotors as all 4 wheels were 1/32 out of true as a precaution. I drove it home about 5 miles with no issues. The next morning I was on my way to work and the codes reappeared with me being governed to 62 mph. At the stop sign I had no braking at all. Pumping the brakes resulted in no braking or pressure in the pedal. Luckily there was no traffic and I was able to use a hill to stop. I turned around and went the mile back to my house and was unable to stop again ending up with the front end in my neighbors yard. I had the vehicle towed back to the dealership where they still have not found a cause or a solution to the issue | Crash: No Fire: No | Unknown |

| Jan 2026 | ENGINE | I pulled up to a traffic light at a busy intersection in Lubbock, TX, and the engine just shut down on approach to a red light. The vehicle still had power (radio, headlights, AC/heater, etc.) but the engine would not start or even turn over and try to start. The vehicle was towed to a Chevy dealership in Lubbock, TX, and they said they believed it was an internal engine failure but wouldn’t be able to look at it for several weeks. I had it transported to my hometown in Taylor, TX, and my certified mechanic replaced the starter and battery solenoid but the engine still wouldn’t start. They drained the oil and found metal shavings in the oil. They too believe that the engine suffered a catastrophic failure and needs to be replaced. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM | The contact owns a 2020 Chevrolet Silverado. The contact stated that while the vehicle was parked, turned off, and unoccupied, the rear of the vehicle caught fire. The fire was initially extinguished by a maintenance worker, and the fire department later applied water to the area to prevent the fire from reigniting. The fire department was unable to determine the cause of the fire, and a fire report was not provided. The contact was unaware whether a police report was filed. The vehicle was not destroyed or towed. The vehicle was taken to a dealer, where it was diagnosed that the rear wiring harness had failed and needed to be replaced.

| Jan 2026 | POWER TRAIN | Rear wheel lockup due to transmission valve body issues. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM | The component that failed was the wiring harness installed in the engine area. the harness was installed right next to a dip stick. The dip stick has a sharp metal piece welded to it and it punctured the harness cutting wires on the inside. This could have been a potential fire hazard. The problem was able to be reproduced, inspected and confirmed by a certified chevy mechanic at Philips Chevy in Frankfort, IL. The mechanic also showed me the failure point on the vehicle upon a visit. The dashboard lights were flashing randomly, headlights were very dim which it very difficult to see, android auto stopped working and not able to use hands free, so that became a safety issue, cruise control stopped working, and was receiving errors for a failed fuel pump. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | What happened: In mid-December 2025, my 2020 Silverado 1500 (VIN: [XXX] ) suffered a catastrophic failure of the DEF Tank Assembly (P/N 84914535) at 29,354 miles—less than 30% of its warranted life. This is a latent design defect involving undersized terminal pins that suffer thermal degradation and melt the connector during high-amperage heater operation in arctic conditions (Ref: GM TSB 21-NA-006). Component Availability: The failed assembly is held at the dealership. I have submitted a "Part Preservation Request" to ensure it is available for forensic inspection by federal regulators. Safety Risk: The failure triggers an EPA-mandated "Limp Mode," initiating a software-forced reduction in speed. Unexpectedly losing speed on high-speed, icy Alaskan highways—where roadside snowbanks prevent safe egress—creates an extreme risk of rear-end collisions. Furthermore, a vehicle restricted to 5 MPH or rendered inoperable in temperatures of -30F to -50F poses a direct, life-threatening risk of cold-weather exposure in remote areas. Confirmation: Failure was confirmed by Lithia Chevrolet GMC of Fairbanks on Jan 7, 2026. GDS2 diagnostic verified DTCs P20B9, P20C1, P205D, and P204C. Data was reviewed by the GM District Manager of Aftersales (DMA) and GM Customer Assistance (Case #[XXX]). Warning Symptoms: Check Engine lamp and "Service Emission System" message appeared in mid-Dec 2025, followed by a "Speed Limited" countdown. The electrical disconnect was abrupt due to terminal pin melting, as documented in my forensic engineering report. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Jan 2026 | POWER TRAIN | Transmission bucks and truck just stops for no reason. | Crash: No Fire: No | Unknown |
| Jan 2026 | ELECTRICAL SYSTEM,ENGINE AND ENGINE COOLING | The contact owns a 2020 Chevrolet Silverado 1500. While operating in negative (-41°F) degree winter conditions, the "Service Emission System" entered an EPA-mandated speed limitation in LIMP Mode messages were displayed. Dealer diagnostics confirmed DTC: P20B9 (Heater Control Circuit Open) and P20C1. The failure was identified as the melting of the Diesel Exhaust Fluid (DEF) tank electrical connector due to undersized terminal pins overheating (Joule heating). The contact stated that it was a latent design defect that posed a fire risk and a safety hazard due to sudden loss of motive power in arctic climates (-45°F). General Motors acknowledged the defect in 2500HD models, Special Coverage: N212342980; but excluded the 1500 models. The failure mileage was 29,354. | Crash: No Fire: No | 29,354 |
| Jan 2026 | POWER TRAIN | I own a 2020 Chevy Silverado 1500, the truck currently has 51,400 miles on it. I started noticing a vibration while driving home from work that continued to get worse. After some quick online research I learned that the torque converter on the newer Chevy and GMC trucks is a weak point in their assembly. This is a very common issue and complaint for owners. The manufacturer has done nothing to resolve it or honor repairs on the defective product. My truck was one month out of the 5 year/60,000 mile warranty, they would not honor repairs because it was outside of the time window. The internal parts break up and destroy a transmission. Luckily i caught it early enough before it caused my transmission to fail while driving. I do not have the part with me. I took the truck to a shop for repairs and they did not return the defective part. No warning lights came on the dash. | Crash: No Fire: No | Unknown |
| Jan 2026 | ENGINE AND ENGINE COOLING | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while his son was driving 75 MPH, there was a knocking sound coming from the vehicle. The driver pulled over and turned the vehicle off, but the vehicle failed to restart. The check engine warning light was illuminated. Upon researching the failure, the contact associated the failure with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The vehicle was towed to the local dealer, where it was diagnosed and determined that the engine had seized. The vehicle was not repaired. The manufacturer was contacted and confirmed that there was no recall coverage on the VIN for the failure. The failure mileage was approximately 165,000. | Crash: No Fire: No Towed | 165,000 |
| Dec 2025 | UNKNOWN OR OTHER | 6L80 transmission shift flared when shifting from 2nd to 3rd gear and shuddered when driving at 45 - 50 mph and about 1400 rpm’s. The Torque Converter Clutch was spasming out causing the the torque converter to shudder which caused the torque converter to overheat at 250 degrees therefore exploding the torque converter that shot metal inside of the transmission blowing it up. | Crash: No Fire: No | Unknown |
| Dec 2025 | POWER TRAIN,ELECTRICAL SYSTEM,UNKNOWN OR OTHER | Bad shuttering, slow acceleration, clunking noise, check engine light flashing all started while driving home. Took it to a transmission shop and they said it was the TC and transmission. I then called the dealership to see if there was a recall, and looked up any recalls. Since I have had fluid flushed and changed, and still have the problems. This has been an on going problem for a couple of years now. It was just out of warranty for dealership to fix. It started while I was on a highway and had very poor acceleration control. | Crash: No Fire: No | Unknown |
| Dec 2025 | ENGINE | The 6.2L engine failed. The same as the 2021-2024 recalls. | Crash: No Fire: No | Unknown |
| Dec 2025 | ENGINE AND ENGINE COOLING | The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving approximately 65 MPH, the vehicle started to hesitate with several unknown warning lights illuminated. The contact stated that there was a misfire in the engine, and her husband pulled off the roadway and turned off the vehicle. The vehicle was restarted and driven back to the residence at speeds no greater than 50 MPH. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the left engine lifters had collapsed and needed to be replaced. The contact was advised by the dealer that the right-side engine lifters should be replaced while the engine was disassembled. The vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 96,000. | Crash: No Fire: No | 96,000 |
| Dec 2025 | ENGINE | The truck had a lifter failure which caused the pushrod to bend damaging the camshaft as well. I spent $5000 dollars just for the problem to happen again. I’ve have spent nearly $10000 on this issue. This not something you expect from a truck that you pay nearly $60000 for. | Crash: No Fire: No | Unknown |
| Dec 2025 | STEERING | Intermittent and sudden loss of power steering. The only message displayed briefly then went out was “service trailer brake controller”. Brought vehicle to Dealership. The grounding strap behind the front right wheel that goes to the frame (Earth Strap) was rotted. This seams to be a very common problem with this model truck and is dangerous. | Crash: No Fire: No | Unknown |
| Dec 2025 | ENGINE | Driving on highway truck lose power, engine lights start to flash and cracking noises start to come from engine. The lose of speed almos cause another vehicle to rear end me, Truck gave no signs or warnings before.

| Dec 2025 | ENGINE | Engine Failure 6 Nov 2025 Yes, engine is available for inspection. Possible loss power, unable to control the vehicle. Vehicle engine failure has been confirmed by dealership, Ruben Milton Chevrolet and Jim Hudson Cadillac in Augusta Georgia. Vehicle has not been inspection by manufacturer, police, insurance representatives. No warning light, no knocking noise, no messages on dashboard. | Crash: No Fire: No | Unknown |
| Dec 2025 | ENGINE | GM declared my original engine as unfixable and decided to replace my engine luckily with 2 weeks remaining in warranty. It had similar clicking noise to everything else I've seen related to this 6.2L having issues. It currently has a new engine that can be inspected if need be. As well as receipt given to me from Klein Chevy from engine replacement. My engine could've failed while driving if I didnt notice the clicking noise prior to getting it looked at. Putting other in danger if driving on a public roadway. Yes the noise/defect was reproducible upon dealer looking at it. Unsure if the vehicle was inspected by the actual manufacturer but they removed my motor and sent it back to the factory. Was never inspected by police or insurance that im aware of There was no check engine light or warning lamps, only thing I noticed was a clicking noise that the common layman would have probably missed, they appeared roughly around 46,000 miles. | Crash: No Fire: No | Unknown |
