The 2004 QX56 was the first year of Nissan's full-size luxury SUV, replacing the QX4 and sharing its platform with the Titan pickup and Armada. It came with a 5.6-liter V8 engine paired with a 5-speed automatic transmission, with rear-wheel or four-wheel drive available. Common service items include the timing chain and tensioners, transmission fluid condition, rear suspension components, and electrical system checks. Regular oil changes and cooling system maintenance are recommended given the engine's size and typical towing use.
