The 2008 Infiniti EX35 represents a pivotal moment for the brand, marking its entry into the competitive luxury crossover segment. Introduced as a response to the growing demand for refined, performance-oriented SUVs, the EX35 promised a blend of sporty handling, plush comfort, and robust power. For owners and potential buyers today, the central question regarding this specific model year revolves around its long-term durability and overall reliability. Understanding the engineering choices and common wear points of the 2008 model is essential for assessing its current value and ownership experience.
Engineering and Platform Foundations
Reliability for the 2008 EX35 is deeply rooted in its shared heritage with the Nissan FM platform, the same architecture underpinning the legendary Infiniti G35 sedan. This connection provided a significant advantage, as the platform was already proven to offer a low center of gravity and responsive handling characteristics. The engineering focus on a balanced weight distribution contributed to a driving dynamics feel that remains a highlight of the EX35. This foundation suggested a structurally sound vehicle from its inception, capable of delivering a premium experience over the long haul.
Powerplant Performance and Durability
The heart of the 2008 EX35 is its 3.5-liter VQ35DE V6 engine, producing 303 horsepower and 253 lb-ft of torque. This powerplant is widely regarded as one of the most reliable engines of its era, provided it receives consistent maintenance. The VQ series has a strong reputation for longevity, often exceeding 200,000 miles with proper care. However, owners should be mindful of the timing chain assembly, which, while generally robust, can be a point of attention during high-mileage ownership. Regular oil changes using the correct viscosity are paramount to ensuring this sophisticated engine continues to perform smoothly well into its later years.
Transmission and Drivetrain Considerations
Paired with the V6 is a smooth-shifting 7-speed automatic transmission, a rarity in its class at the time. This transmission plays a crucial role in the EX35’s reliability profile. When functioning correctly, it delivers seamless power delivery and efficient gear changes. Yet, like all complex electronic machinery, it is not without potential issues. Some owners have reported sporadic transmission hesitation or harsh shifting, particularly if the transmission fluid has not been changed at the recommended intervals. Adhering to the maintenance schedule for the transmission fluid is a critical step in preventing these electronic control problems and ensuring the longevity of the drivetrain.
Handling, Comfort, and Common Wear Items
The EX35 is celebrated for its engaging driving dynamics, which set it apart from many of its softer-riding competitors. This sporty tuning, however, places additional stress on certain components over time. The front strut mounts and rear control arm bushings are known wear items, often requiring replacement between 60,000 and 100,000 miles. Neglecting these components can lead to noticeable clunks, uneven tire wear, and a decline in handling precision. On the comfort side, the leather-wrapped steering wheel and premium Bose audio system have proven to be durable and reliable, maintaining their quality and function throughout the vehicle's life.
