Summary

The 2006 Chevrolet W4500 Tiltmaster is a capable workhorse, but it is not without its issues. Engine problems, such as turbocharger solenoid failure and fuel injector sticking, can be costly to repair. The Allison 1000 transmission may also experience TCM failures, leading to erratic shifting. While the suspension and electrical components have some common issues, they are generally less severe. Interior issues, such as climate control malfunction and instrument cluster failure, can diminish the overall driving experience. Rust concerns should also be considered when purchasing a used W4500. Overall, the severity and cost of the issues vary, and potential buyers should research and consider the potential risks before making a decision.
