Reviews On 2009 Nissan Maxima

The 2009 Nissan Maxima marked a significant shift for the nameplate, moving it further upscale and attempting to recapture some of the "4-Door Sports Car" magic of its earlier iterations. As an experienced DIYer, understanding the intricacies of this particular model year is crucial, especially if you're considering purchasing one, maintaining one, or even thinking about modifications. This article delves into the technical aspects and common reviews, providing you with the knowledge to make informed decisions.

Powertrain & Drivetrain: The Heart of the Maxima

At the core of the 2009 Maxima lies the VQ35DE engine, a 3.5-liter naturally aspirated V6. This engine, part of Nissan's widely acclaimed VQ engine family, is known for its robust performance and relative reliability. However, even a well-engineered engine has its quirks.

Technical Specifications:

Displacement: 3.5 liters (3498 cc)
Configuration: V6, DOHC (Double Overhead Camshafts), 24 valves
Horsepower: 290 hp @ 6400 rpm
Torque: 260 lb-ft @ 4400 rpm
Compression Ratio: 10.3:1
Fuel Delivery: Sequential Multiport Fuel Injection (SMFI)

The VQ35DE in the 2009 Maxima features continuously variable valve timing (CVTCS) on both the intake and exhaust camshafts. CVTCS, or Continuously Variable Timing Control System, optimizes valve timing based on engine load and speed, improving both fuel economy and performance. This technology, while generally reliable, can sometimes be a source of issues. Listen for any rattling or unusual noises on startup, which could indicate a problem with the CVTCS actuator or oil pressure to the system.

Transmission: The sole transmission option in 2009 was an Xtronic CVT (Continuously Variable Transmission). This is perhaps the most controversial aspect of the car. While CVTs offer seamless acceleration and can improve fuel economy, they are often criticized for their driving feel and long-term reliability compared to traditional automatic transmissions. Nissan has refined their CVT technology over the years, but the early versions still have a higher failure rate than traditional automatics. Pay close attention to the transmission's behavior during a test drive. Look for smooth, consistent acceleration without any slipping or hesitation. A properly functioning CVT should provide a different experience than a stepped-gear transmission; it's a constant, uninterrupted power delivery.

Important Note: CVT fluid changes are critical to the longevity of the transmission. Use only Nissan NS-2 CVT fluid (or a compatible, high-quality synthetic CVT fluid) and follow the recommended service intervals. Neglecting this will significantly shorten the life of the transmission. Many failures can be traced back to improper or infrequent fluid changes. Consider doing a drain and fill more frequently than the manufacturer's recommendation, especially if you drive aggressively or live in a hot climate. And remember, there is no transmission filter to change.

Suspension, Brakes, and Steering: Handling and Control

The 2009 Maxima boasts a four-wheel independent suspension, with struts up front and a multi-link setup in the rear. This configuration provides a good balance of ride comfort and handling, contributing to its sporty feel. Here's what you should be aware of:

Front Suspension: MacPherson struts with coil springs and stabilizer bar.
Rear Suspension: Multi-link independent suspension with coil springs and stabilizer bar.
Brakes: Four-wheel disc brakes with ABS (Anti-lock Braking System), EBD (Electronic Brakeforce Distribution), and Brake Assist.
Steering: Vehicle-speed-sensitive power steering.

Common Issues:

Strut Mounts: The front strut mounts are prone to wear and tear, especially on vehicles driven on rough roads. Listen for clunking or rattling noises when going over bumps.
Rear Suspension Bushings: The various bushings in the rear multi-link suspension can dry rot and crack over time, leading to sloppy handling and increased tire wear. Inspect these bushings carefully for any signs of damage.
Brake Rotors: The brake rotors can be susceptible to warping, especially if the brakes are frequently used aggressively. Look for pulsations in the brake pedal when braking. Resurfacing or replacing the rotors may be necessary.
Power Steering Pump: The power steering pump can develop leaks over time. Check the fluid level regularly and look for any signs of leakage around the pump and hoses.

Electronics and Interior: Comfort and Technology

The 2009 Maxima offered a range of electronic features, depending on the trim level. Here are some common areas to inspect:

Navigation System: If equipped, the navigation system can become outdated. Updating the maps may be costly or unavailable. The screen itself can also fail over time.
Audio System: The Bose audio system, if equipped, can experience speaker failures. Test all the speakers to ensure they are working properly.
Climate Control: The climate control system can develop issues with the blend doors, which control the flow of hot and cold air. Listen for clicking noises behind the dashboard when adjusting the temperature.
Power Windows and Locks: These systems are generally reliable, but the window regulators can fail over time, causing the windows to operate slowly or not at all.
Key Fob: The key fobs can be prone to battery drain or malfunction. Ensure the fob is working properly and that you have a spare key.

Common Problems and Reliability: What to Watch Out For

Here's a summary of the most common problems reported by owners of the 2009 Nissan Maxima:

CVT Transmission Failure: As mentioned earlier, this is the most significant concern. Proper maintenance is key to mitigating this risk.
Oil Consumption: Some VQ35DE engines can exhibit excessive oil consumption. Check the oil level regularly and monitor for any signs of blue smoke from the exhaust, which indicates burning oil. This can be caused by worn piston rings or valve stem seals.
Timing Chain Tensioner: While not as common as some other VQ engines, the timing chain tensioner can fail, leading to engine noise and potential engine damage. Listen for a rattling noise on startup.
Catalytic Converter Failure: Catalytic converters can fail, especially if the engine is burning oil. This can result in poor performance and a failed emissions test.
Oxygen Sensors: Oxygen sensors can fail, leading to poor fuel economy and a check engine light.

Overall Reliability: The 2009 Maxima can be a relatively reliable car if properly maintained. However, the CVT transmission is a potential weak point. Thoroughly inspect the car before purchasing, paying close attention to the transmission's behavior and service history.

Modifications and Performance Upgrades: Unleashing the Potential

The VQ35DE engine is a capable platform for performance upgrades. Here are some common modifications:

Cold Air Intake: A cold air intake can improve airflow to the engine, resulting in a slight increase in horsepower.
Exhaust System: An aftermarket exhaust system can improve exhaust flow and give the car a sportier sound. Consider a cat-back system for a good balance of performance and sound.
ECU Tuning: A custom ECU tune can optimize the engine's performance for specific modifications and driving conditions. This requires specialized knowledge and equipment.
Suspension Upgrades: Lowering springs or coilovers can improve handling and give the car a more aggressive stance.
Brake Upgrades: Upgraded brake rotors and pads can improve braking performance, especially for aggressive driving.

Important Note: When modifying your car, always ensure that the modifications are compatible with each other and that they do not compromise the car's reliability or safety.

Final Thoughts: A Considered Choice

The 2009 Nissan Maxima offers a blend of performance, luxury, and practicality. However, potential buyers should be aware of the common problems, particularly the CVT transmission. A thorough inspection, a detailed service history review, and careful maintenance are essential to ensure a positive ownership experience. If you are comfortable with potential CVT repairs and understand the specific needs of this model, a well-maintained 2009 Maxima can be a rewarding vehicle.
