What Problems Does the 2021 Chevrolet Silverado 3500HD Have?
Frequently reported problems for the 2021 Chevrolet Silverado 3500HD include issues with the infotainment system, such as freezing or lagging. Some owners have reported problems with the diesel exhaust fluid (DEF) system, particularly sensors and injectors. Transmission issues, though not widespread, have been noted. Certain recalls may have been issued for the 2021 model year, and it is important to check the NHTSA website for the latest recall information.
Long-term reliability concerns often revolve around the complexity of modern diesel engines. The Duramax diesel is generally considered robust, but proper maintenance is essential for longevity. Issues with the high-pressure fuel system, turbocharger, and emissions control components can arise over time.
Specifically for the 2020-2021 model years, some owners reported instances of cracked pistons in the 6.6L Duramax diesel engine, though this wasn't a widespread issue. Electrical gremlins, particularly those involving the infotainment system and driver-assistance features, are also worth investigating before purchasing a used model. Always check the vehicle history report and perform a thorough inspection before buying a used 2021 Silverado 3500HD.
