Summary
The 2007 Chevrolet Silverado 2500HD, while a capable truck, can experience a range of issues. The Duramax diesel is generally robust but can suffer from fuel injector and turbo issues which can be expensive. The 6.0L gas engine has known oil consumption issues. Both automatic transmissions can present problems with slipping. Suspension wear is a common issue due to the heavy-duty nature of the truck. Electrical gremlins, such as instrument cluster failures and 4WD actuator problems, are also potential headaches. Rust on rocker panels and cab corners is another factor to consider, especially in areas with harsh winters. Overall, potential buyers should have a thorough inspection performed, paying particular attention to the engine, transmission, and undercarriage, to avoid costly repairs down the line.
