Summary Verdict
The 2009 GMC W4500 Forward demonstrates generally good reliability for a commercial vehicle. The 5.2L diesel engine, while robust, can experience issues with its Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) system, particularly under demanding operational cycles. These are common to many modern diesel powertrains and are often manageable with proper maintenance and regeneration procedures. The transmission, suspension, electrical system (aside from occasional alternator or wiring concerns), exterior, and interior components are largely free from widespread, significant issues. Proactive monitoring of the DPF and EGR systems, along with regular checks of the electrical components, will contribute to the longevity and operational efficiency of the W4500 Forward.
