Trim / Codes
The 2002 Nissan Q45 introduced the model's third-generation redesign, featuring a new 4.5-liter V8 engine producing approximately 340 horsepower and a five-speed automatic transmission. A sport-tuned Q45t trim was offered, along with available features such as HID headlights and a navigation system. Common service considerations include ignition coil failures, valve cover gasket leaks, and wear of suspension bushings and control arms as mileage accumulates. The engine uses a timing chain rather than a belt, so no timing belt replacement interval applies, though consistent oil changes remain important for long-term reliability.
