Summary Verdict
The 2006 Chevrolet Silverado 2500, particularly with the Duramax diesel engine and Allison transmission, is generally a durable truck. However, owners should be aware of potential issues like intake manifold leaks and cracked heads on the gasoline V8, and glow plug/injector problems on the diesel. Transmission issues are less common on the Allison but can occur with the 4L80-E. Suspension components like ball joints and leaf springs may require attention due to the truck’s heavy-duty nature. Electrical components such as alternators and window motors can fail. Exterior rust is a common concern for trucks of this age, and interior wear on seats and HVAC systems are also noted. Overall, with proper maintenance and addressing these known issues, the 2006 Silverado 2500 can remain a reliable workhorse.
