This page covers 10 recalls and 98 owner complaints for the 2020 Chevrolet Silverado 2500.
Powertrain complaints dominate what 2020 Silverado 2500 owners report, with the 3.0-liter Duramax diesel drawing the most attention. Owners describe coolant ingestion leading to hydrolocked engines, gear selector failures where the transmission doesn't recognize park, leaving the truck unable to restart, and general drivability concerns. Tires and service brakes each generate a smaller but notable share of complaints. Brake-related reports often involve the electric trailer brake controller triggering a service warning, sometimes persisting even when no trailer is connected. A few owners also describe unintended tailgate opening while towing. Tire complaints tend to center on premature wear or failure rather than a single consistent failure mode.

By System
The 2020 Chevrolet Silverado 2500 has 10 recalls, the most serious involving a transmission control valve that can cause the rear wheels to lock up without warning, raising the risk of a crash.
Prior repair attempts for the transmission issue did not fully resolve the problem for some vehicles, so the defect spans multiple campaigns. A separate drivetrain concern involves a driveshaft joint that can separate while driving, cutting propulsion. The hood latch striker wire can fracture and allow the hood to fly open at speed, and again, an earlier repair did not cover all affected trucks. On the fire and restraint side, the front seatbelt pretensioners on vehicles with carpet flooring can vent hot gas when they deploy, potentially igniting the carpet. The front-row center seat belt bracket may not be secured to the seat frame, leaving that occupant without proper restraint in a crash. The roof-rail curtain airbag inflator has a diffuser component that can break free during deployment, reducing the airbag's effectiveness. Vehicles equipped with a 17-inch spare tire paired with larger accessory road tires can lose anti-lock brake function at the rear wheels. The power-unlatching tailgate can short circuit from water intrusion and swing open while driving, spilling cargo into traffic.
