The 2004 Nissan Maxima is a midsize four-door sedan that blends near-sport-sedan performance with everyday comfort and practicality. It’s part of the fifth-generation Maxima (2000–2003) with a refreshed look and updated features for 2004, positioning it as Nissan’s “four-door sports car” alternative to family sedans. Ideal for drivers who want strong V6 power, a roomy cabin, and an upscale feel without premium-brand pricing, it competes with models like the Honda Accord V6, Toyota Camry V6, and Acura TL of the era. For shoppers researching “2004 Nissan Maxima reliability” and “2004 Nissan Maxima problems,” it’s a solid car when maintained, but there are several well-known trouble spots to watch.

1) 3.5L V6 (VQ35DE): The 2004 Maxima is powered by Nissan’s 3.5-liter V6, known for strong torque and smooth acceleration, typically rated around 265 hp depending on trim and transmission. It delivers quick passing power and a sportier feel than many midsize sedans from the same time. 2) Transmission choices: Many 2004 Maximas came with a 5-speed automatic, while some trims offered a 6-speed manual for drivers who want more control and engagement. 3) Sport-tuned driving character: Steering response and chassis tuning are more performance-oriented than typical family sedans, especially on higher trims with upgraded wheels/tires. 4) Comfort and convenience upgrades: Depending on trim, you may find leather seating, heated front seats, power-adjustable driver’s seat, premium audio, and a sunroof, giving the Maxima an entry-luxury vibe. 5) Safety and structure: Strong body structure and available features for the time made it a competitive option for daily commuting and highway driving, especially when equipped with properly maintained brakes and tires.

For shoppers searching “2004 Nissan Maxima common issues,” these are some of the most commonly reported problems. Not every car will experience them, but they’re worth checking closely—especially above 100,000 miles. 1) Ignition coil and spark plug-related misfires: A frequent complaint is rough running, hesitation, or a flashing check engine light due to failing ignition coils. This can show up around 80,000–140,000 miles, often triggered by heat and age. If ignored, misfires can damage the catalytic converters. 2) Oil leaks and oil consumption concerns: The VQ35DE can develop valve cover gasket leaks or seepage over time, sometimes noticeable around 100,000+ miles. Some owners also report higher oil usage as mileage climbs, so consistent oil level checks matter. 3) Suspension wear and front-end noises: Worn struts, sway bar end links, control arm bushings, and engine mounts can cause clunks, vibrations, or loose steering feel. Many owners encounter front suspension refresh needs somewhere between 90,000–150,000 miles depending on road conditions. 4) Catalytic converter and O2 sensor issues: Check engine lights related to efficiency codes or oxygen sensor faults are common on higher-mileage cars, particularly if the engine has been run with misfires or oil burning. Repairs can be costly, so catching misfires early is key for long-term 2004 Nissan Maxima reliability.
