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.

ELECTRICAL SYSTEM, ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:UREA INJECTION SYSTEM (DEF)
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.

ENGINE, ELECTRICAL SYSTEM, 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 -30°F to -50°F 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.

My vehicle was part of the recall N25494000 L87 Engine loss of propulsion. Vehicle went in for recall on Sep-30th 2025, PicoScope Inspection was done and vehicle passed. Oil was changed to 0W 40 with new oil filter. Dec-26/27 of 2025 vehicle started stalling, for no reason but no Engine light. The dealer said there was no problem because there was no engine light, so there was no way to find out what was wrong. January 11th 2026 vehicle lost propulsion 7 times on the freeway, vehicle had a hard time re-starting and started smelling oil burning smell. Vehicle Engine light stayed on, 1/11/2026 vehicle was running a little rough with abnormal tapping noise but made it to the dealer for inspection.

POWER TRAIN
While driving, the 10l1000 transmission in the truck attempted to shift from 6th gear to 7th gear. The transmission locked up causing a violent "buck" from the rear end of the truck. The road was icy and could have caused the truck to lose control due to the lock up of the rear wheels. After getting the truck to a repair shop, valve body was deemed the cause of the failure. A complete transmission replacement is needed. Had I lost control of the vehicle due to the lock up, my family and other motorists would have been put at risk of severe injury or worse. No warning lights were illuminated prior to failure.

ENGINE, FUEL/PROPULSION SYSTEM
Driving south on I95 under normal condition. After driving for about a hour truck started smoking under the hood. I pulled over and turned off vehicle. I released the latch to open hood. When I got out of the vehicle to lift the hood there were flames coming from both sides of the hood. I did not lift the hood. I moved away from the vehicle and called 911. Police and fire department responded and extinguished the fire. Vehicle was a total loss. GM indicates they will not investigate the cause and I should work through my insurance company for compensation.

On December 12th, while on interstate 10, my engine started making clanking noise, it started to stall and jerk. I had try to get over to the shoulder of the interstate. I had to restart the truck to try and get off the interstate. It died out. I tried to restart and it did, just enough for me to get it off the interstate. It was finally towed to the dealership. The mechanic said it wasn’t under warranty. They say the rocker atms are bent and 2 pistons were damaged the charge The mechanic also said that my engine in my truck was too small for my truck. He doesn’t know why they use it …. They want $8700 to make the repairs, GM will not assist in cost off to r repair. I’ve come to find out this is a common problem in this model of my truck.

While driving on Highway 35 in Austin, Texas, my vehicle's transmission unexpectedly failed, which placed myself and my passengers in a precarious situation. The vehicle became inoperable on the side of the highway, necessitating that my passengers and I manually push it while traffic was actively flowing. This mechanical issue occurred without any prior indication. Through my subsequent research, I have observed that this particular problem appears to be a recurring concern with this model of vehicle.

FUEL/PROPULSION SYSTEM, ENGINE, POWER TRAIN
My pickup truck has a Duramax diesel engine with a CP4 diesel injection pump. That pump has not failed yet in my truck. However it has been known to fail in numerous other GM vehicles with Duramax engines and when it does fail the engine comes to a complete stop and cannot be restarted. This is a potentially hazardous even fatal situation. Repair if the pump fails is very expensive - $12,000 to $14,000 in some cases. I would like GM to replace the injection pump at my dealership to ensure this known failure does not occur. My pickup truck is otherwise in excellent condition.

ENGINE AND ENGINE COOLING
The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that the vehicle was consuming an excessive amount of engine oil. The vehicle was taken to an independent mechanic, who informed the contact that similar vehicles were known for excessive oil consumption. The contact was adding oil every 500 - 1,000 miles driven, because the message "Engine Oil Low - Add Oil" would be displayed on the instrument panel. The contact was later alerted by a friend that, upon leaving his residence, oil from the vehicle had leaked out onto the driveway. The vehicle was taken to another independent mechanic, who discovered that a line in the engine oil cooler was leaking oil from a detached crimp joint. Upon investigation, the contact discovered Customer Satisfaction Program: N212326940; for the failure. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in the CSP. The contact was referred to the NHTSA Hotline to report the failure. The vehicle was repaired. The failure mileage was approximately 105,000.
