The 2009 Infiniti M35 is equipped with Nissan’s VQ35HR 3.5-liter naturally aspirated V6 engine, producing 303 horsepower and 262 lb-ft of torque. This aluminum DOHC engine features Variable Valve Event and Lift (VVEL) technology for improved performance and fuel economy. The VQ35HR is part of Nissan’s award-winning VQ engine family and includes features like electronic throttle control, dual intake manifolds, and a drive-by-wire system. The engine is mated to a CVT automatic transmission and is available in both rear-wheel drive and all-wheel drive configurations, delivering smooth power delivery and respectable fuel economy for a luxury sedan of this size.

The 2009 Infiniti M35 shares most parts with the 2006-2010 M35 model years, as this represents the second generation of the M-series. Engine components from the VQ35HR are largely interchangeable across these years, though some sensors and wiring harnesses may have minor variations. Body panels, interior trim, and suspension components are generally compatible within the 2006-2010 range. Some electrical components and modules may require programming or may have different part numbers between early and late production years. The CVT transmission components are compatible across 2007-2010 models, as 2006 used a different transmission. Always verify part numbers and VIN compatibility, especially for electronic modules, as running changes occurred throughout production.

The VQ35HR 3.5L engine in the 2009 M35 is generally reliable when properly maintained, though it has some known issues. The VVEL system can be problematic and expensive to repair, but the core engine internals are robust. Regular oil changes every 5,000 miles are crucial, as the VVEL system is sensitive to oil quality. The timing chain and guides typically last well beyond 150,000 miles with proper maintenance. Common maintenance items include spark plugs every 60,000 miles and air filters regularly. While not as bulletproof as earlier VQ engines, the VQ35HR can provide reliable service with attentive maintenance, though repair costs tend to be higher due to the complex VVEL system and luxury car pricing for parts.
