My 2026 Chevrolet Silverado 3500 with the 6.6L Duramax diesel has experienced three separate P2463 Diesel Particulate Filter excessive soot accumulation events at approximately 4,300, 5,500, and 10,280 miles. Each event required a Chevrolet dealer to perform a forced regeneration to restore normal operation. The most serious event occurred while towing an approximately 15,000-pound loaded dump trailer on a public county road. While climbing a hill, the truck entered reduced-power/limp mode associated with the emissions/DPF system. Power was reduced so severely that the truck could no longer continue uphill and came to a stop in the travel lane. This created a safety hazard because the road was narrow and winding, with no safe place to pull off. I had to back the truck and loaded trailer several hundred yards downhill while traffic was present behind me. Before the event, the truck displayed “Continue Driving, Cleaning Exhaust Filter.” The warning did not state that severe power reduction or loss of towing capability was imminent. I did continue operating the vehicle, but the truck was being used for normal commercial towing/work operations where immediate highway-speed driving was not practical. The issue has been confirmed by Chevrolet dealers through DTC P2463 on multiple visits. The only correction performed has been forced regeneration. I was advised that no failed component was identified and no permanent repair has been performed. The vehicle is available for inspection, and repair records are available. My concern is that the emissions-related derate strategy can cause sudden and severe loss of motive power while towing on public roads, leaving the vehicle unable to maintain forward movement or safely clear the travel lane. This has occurred repeatedly during normal work use, not as a one-time event, and the warning provided did not give a clear indication that the truck could soon become unable to tow or maintain forward movement.

What 2026 Chevrolet Silverado 3500 owners say
Most recent owner complaints, unedited.
I purchased a brand-new Chevrolet dually truck from Bomnin Chevrolet Dadeland in Miami, Florida. Since delivery, the vehicle has had serious unresolved defects and safety concerns. The truck has ongoing alignment issues that the dealership has been unable or unwilling to properly repair. The vehicle does not drive correctly and there are concerns regarding safe operation while hauling. In addition, a major issue has now developed involving the rear passenger door. The rear door does not properly close and latch securely. This creates a serious safety concern because the door may open unexpectedly while driving. I brought these issues to the dealership under warranty, but the problems remain unresolved. I was also informed that the dealership could not properly perform the alignment on the dually truck. This vehicle was sold new and should not have these defects. I am filing this complaint due to concerns about vehicle safety, defective components, and inability to obtain proper warranty repairs.
