Trim / Codes

The 2001 Nissan Q45 was the final year of the second-generation flagship sedan, carrying over its 4.5-liter V8 engine and four-speed automatic transmission with only minor equipment and trim revisions. It was offered in base and Q45t trims, with the t model featuring a sport-tuned suspension and additional standard equipment. Common service considerations include timing belt replacement, suspension component wear, and attention to aging electrical systems. Regular transmission fluid service and monitoring for oil consumption are also recommended on higher-mileage examples.
