Summary

The 2008 Chevrolet Kodiak C4500, particularly with the Duramax diesel, can be prone to issues related to fuel system components (injectors, fuel filter housing) and turbocharger. Suspension and electrical problems, common in work trucks, are also noted. Interior HVAC issues are relatively minor. Repair costs can range from a few hundred dollars for smaller fixes to several thousand for major engine or transmission work. While reliable when properly maintained, potential buyers should be aware of these common issues and factor potential repair costs into their purchasing decision.
