A warning light illuminated as the driver was pulling into a bank parking lot. The vehicle was left running while the driver briefly stepped away to use the ATM. When he returned, he saw smoke coming out of the glove compartment. When the glovebox was opened, an active fire was already burning inside the dash cavity behind it. The fire grew rapidly and resulted in full cabin flashover, destroying the interior, melting wiring, and causing structural damage. The burn pattern clearly shows the fire originated inside the passenger-side dash/glovebox area, not the engine compartment. Photographs taken immediately after the incident show melted and fused copper wiring, arc beads, vaporized insulation, and connectors burned from the inside outward. Harness bundles were burned from the inside out, consistent with electrical arcing. A torch lighter stored in the glovebox did not ignite and played no role in the fire. Chlorine stored in the truck bed is a non-combustible oxidizer and cannot ignite or melt wiring. These facts eliminate external ignition sources. The area behind the glovebox contains multiple electrical components with known failure modes, including the body control module, fuse block, HVAC blower motor resistor, and airbag wiring harness. The warning light appearing shortly before the fire and the fire beginning while the vehicle was left running strongly indicate an internal electrical failure. The manufacturer inspected the vehicle and issued a denial but has refused to release photographs, diagnostic logs, investigator notes, or the third-party report, preventing independent verification of the cause.

Intermittent complete loss of all audio output on a 2026 Chevrolet Silverado 2500HD (VIN [XXX], purchased new XXX). When the fault occurs, the vehicle produces no sound of any kind for the entire drive cycle. This includes the audible turn signal confirmation, the seat belt reminder chime, door and key chimes, and the audible alerts for the driver assistance systems (forward collision alert, lane departure, blind spot, park assist). All audible warning capability in the vehicle is lost simultaneously. The failure is intermittent and occurs without warning. It has recurred on multiple dates, most recently XXX during normal highway driving. The dealer performed a global reset per GM's instructions; audio returned, then the fault recurred approximately two weeks later. The reset provides temporary masking, not a repair. This is a known, unresolved GM defect. GM bulletin PIT6406 has covered this condition since XXX replacing two earlier bulletins on the same symptom, and has been revised approximately nine times through XXX. It remains classified as "Preliminary Information" rather than a finalized TSB. GM's own text states engineering is still investigating and instructs that the customer continue driving the vehicle in the interim. The bulletin covers 2022-2026 Silverado and Sierra 1500/2500/3500, Tahoe, Suburban and Yukon. GM has previously treated this same failure mode as a safety defect. the federal safety agency recall 16V084 and 16V422. Safety consequence: this is a heavy-duty truck used regularly for towing. When the fault is active, the driver receives no audible indication that a turn signal has been left on, no audible collision or lane departure warning, and no seat belt reminder. The vehicle gives the driver no indication the audio system has failed until a warning is needed and does not sound. Operators have no way to know their audible warning systems are inoperative at any given moment. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This vehicle was delivered new without a printed owners manual. There are multiple open recalls for other 2026 model year Chevrolet Silverados that were also delivered without printed owners manuals, however my VIN was incorrectly omitted from the recall population. I only became aware this week that my vehicle was incorrectly excluded from these campaigns.

The contact owns a 2026 Chevrolet Silverado 2500. While driving 65 MPH, the vehicle lost motive power and the steering wheel seized, and the brakes failed to stop the vehicle. White smoke with a burning odor was coming from the engine compartment. The vehicle was on an incline, which helped the vehicle to decelerate. The contact pulled off the road and came to a stop with smoke billowing under the hood. A Sheriff driving by called the fire department. The fire fighters arrived and determined that the smoke had become extinguished. The vehicle was towed to the dealer, who determined that the fuel line had ruptured and there was diesel fuel collecting inside the engine compartment. The contact was informed that the fuel system had a catastrophic failure and the engine needed to be disassembled for further diagnostic tests. The manufacturer was notified of the failure by phone and a case was filed. The failure mileage was approximately 9,100.

Two steering issues on the same 2026 Silverado 2500 HD LTZ Trail Boss Z71, 6.6L gas, truck has about 11,000 miles as of 09/29/2026. 1. Mechanical clunk heard and felt through the steering wheel over bumps and when the wheel is at full lock. Assist is still present; the wheel does not spin free. This matches wear/lash in the upper intermediate steering shaft (the collapsible shaft between the column and the steering gear), not the tilt mechanism. Fluid is not low and there is no visible leak. 2. Separate hissing / hydraulic-flow noise heard inside the cab from the column area when tension is applied to the wheel. There is no hydraulic fluid in the column; the noise is conducted up the shaft from the hydraulic steering gear / Digital Variable Assist (NV8) system. I am reporting both so they stay on one VIN record. 3. Both symptoms were present when I purchased the truck new on 11/25/2025 and Chevrolet dealer checked it before delivery, they said it was normal. On my first service, the truck was taken to a GMC dealer where they also stated this was normal. Now both symptoms have gotten worse and the hiss has gotten louder.

The contact owns a 2026 Chevrolet Silverado 2500. The contact stated that while operating the vehicle and depressing the brake pedal, there was a grinding sound coming from the front passenger's side wheel. Later, while driving slowly toward a stop sign, the brake pedal was depressed; however, the vehicle failed to respond and traveled through a four-lane intersection. The vehicle was driven to a local service center where the failure recurred while reversing into a parking space, and the vehicle struck a curb. Upon removing the front passenger's side wheel, an independent mechanic discovered that the inner brake pad was missing and the brake caliper was lodged against the brake rotor. The vehicle was towed to a local dealer, where it was diagnosed that the front brake pads and calipers had failed and needed to be replaced. The cause of the failure was not determined. The failure mileage was 24,052.

I am reporting a serious and extremely concerning brake failure involving my 2026 Chevrolet Silverado 2500 Diesel. Traffic ahead of me began to slow down. I saw the traffic slowing and immediately began applying the brakes to slow my vehicle. Although I was pressing the brake pedal, the truck was not slowing or stopping as it should have. When I realized the vehicle was not going to stop, I pressed the brake pedal as hard as I possibly could. The brake pedal went completely down to the floor, yet the vehicle still failed to stop, resulting in a collision. I want to be very clear: I saw traffic slowing, I applied the brakes, and when the truck failed to respond properly, I applied maximum pressure to the brake pedal. Despite this, the brake pedal traveled all the way to the floor and the vehicle did not stop. Because of the seriousness of the incident and our concern regarding the braking system, we had the vehicle towed from the scene rather than driving it. This was an extremely dangerous incident involving a 2026 vehicle. A braking system that fails to respond when the driver is actively attempting to stop presents a serious safety concern and could result in severe injury or death. I am requesting that this incident be formally documented and thoroughly investigated as a potential vehicle safety defect. I also request that all relevant vehicle data, diagnostic information, braking-system data, and electronic crash data related to this incident be preserved and reviewed.
