The 6.6L Duramax diesel, while powerful, can be prone to issues with fuel injectors and glow plugs, which are common in high-mileage diesel applications. The Allison 1000 transmission is robust but can experience torque converter shudder or overheating under heavy use, often requiring maintenance or upgrades. Suspension components like ball joints and leaf springs may require attention due to the truck’s intended heavy-duty use. Electrical issues, such as alternator failure or BCM problems, can occur but are not overwhelmingly prevalent. Overall, the Silverado 3500 HD offers good reliability for its class, with potential issues primarily centered around the diesel powertrain and heavy-duty suspension components.
