Summary

The 2015 GMC Savana 4500, while generally reliable, can experience issues across various components. Engine issues, particularly oil consumption and catalytic converter failure in the gasoline engines, and DPF problems and fuel injector failures in the diesel engine, are common and can range from relatively inexpensive to costly repairs. Transmission problems, such as torque converter shudder and harsh shifting, can also be problematic. Suspension issues such as leaf spring sagging and worn ball joints affect the vehicle’s handling and ride comfort. Electrical issues like faulty door lock actuators and battery drain, as well as exterior issues with the sliding door, and interior HVAC and seat belt problems also occur. The severity and cost of these issues vary, but some, especially those related to the engine and transmission, can lead to significant expenses.
