Summary Verdict
The 2005 Chevrolet Silverado 3500 is a capable workhorse with a generally solid reputation for reliability, particularly its powertrains. The Duramax diesel engine, while robust, can experience issues with glow plugs, injectors, and the EGR system, which are common for diesel engines of this era. Gasoline V8s are generally dependable but can suffer from intake manifold leaks. Automatic transmissions, especially the 4L80-E, may require torque converter attention. Suspension components like ball joints and leaf springs are subject to wear due to the truck’s heavy-duty nature. Electrical gremlins, such as alternator failure or BCM issues, can occur. Rust is a significant concern for vehicles in corrosive environments. Overall, with proper maintenance and addressing specific known issues, the 2005 Silverado 3500 can remain a reliable truck.
