Overview

The 2009 Infiniti FX35 is a midsize luxury crossover SUV built for drivers who want sporty handling, strong V6 power, and premium features without stepping up to a full-size SUV. It belongs to the second-generation FX (introduced for the 2009 model year), which brought a bolder design, upgraded technology, and a more refined cabin compared to earlier FX models. The FX35 competes with models like the BMW X5 and Acura MDX, leaning more toward performance and style than maximum cargo space. It’s ideal for commuters and small families who value road feel, acceleration, and upscale comfort.

Key Features

- 3.5L V6 engine (VQ35HR) with strong horsepower and a sporty character; most models are paired with a 7-speed automatic transmission for smoother acceleration and improved highway cruising. - Available rear-wheel drive or intelligent all-wheel drive (AWD), giving buyers a choice between a sportier feel (RWD) and added all-weather traction (AWD). - Sport-oriented chassis tuning for a luxury crossover, with confident cornering and responsive steering compared to many softer-riding competitors. - Premium interior options typically include leather upholstery, power front seats, Bose audio, and available navigation, with a driver-focused cockpit design. - Distinctive exterior styling and a higher-end market position, making it a standout choice for shoppers who prioritize design and performance in a luxury SUV.

Common Issues & Reliability

Shoppers researching “2009 Infiniti FX35 problems” and “2009 Infiniti FX35 reliability” will find the FX35 can be a solid long-term vehicle when maintained, but a few “2009 Infiniti FX35 common issues” show up regularly. 1) Oil consumption and minor oil leaks: Some owners report higher-than-expected oil use as mileage climbs, often becoming noticeable around 80,000–120,000 miles. Valve cover gasket seepage can also occur, leading to burning-oil smells or oil on the engine. 2) Suspension wear (control arms, bushings, shocks/struts): Because the FX35 is tuned for sporty handling and often runs larger wheels, front suspension components can wear faster than on softer SUVs. Clunks over bumps, uneven tire wear, and steering vibration can show up around 70,000–120,000 miles depending on road conditions. 3) Exhaust and heat-related issues: Exhaust leaks or noisy exhaust components can develop with age, and some owners report heat-related wear in under-hood plastics and rubber. Symptoms may include rattles, ticking sounds, or exhaust smell, especially on higher-mileage vehicles. 4) Electrical and convenience feature glitches: As these vehicles age, issues can appear with power door locks, window regulators, backup camera or infotainment functions, and intermittent warning lights. These tend to be more “annoyance” problems than drivability failures, but diagnosis can take time.
