Summary Verdict

The 2007 Chevrolet T6500 demonstrates reasonable reliability for its class, with the Isuzu 5.2L diesel engine being a generally dependable unit, though issues with the EGR cooler and turbocharger can arise. DPF clogging is a common concern for diesel vehicles of this era and requires diligent maintenance. The Allison 1000 automatic transmission is robust, but torque converter problems can occur. Electrical system issues, particularly related to wiring harness corrosion and alternator failure, are noted. The suspension, exterior, and interior components are largely free of widespread critical failures. Proactive maintenance, especially concerning the emissions system and electrical connections, is key to maximizing the longevity and operational efficiency of the T6500.
