Overview

The 2012 Infiniti FX35 is a midsize luxury crossover SUV known for sporty handling, aggressive styling, and a premium feel that leans more performance than utility. It’s ideal for drivers who want a powerful V6, rear-biased driving dynamics, and upscale features without stepping up to a larger, heavier SUV. For 2012, the FX35 remains part of the second-generation FX (introduced for 2009), positioned as a style-forward alternative to more traditional luxury crossovers. It competes with models like the BMW X5 and Acura MDX, but stands out with its coupe-like profile and road-focused character.

Key Features

1) 3.5L V6 PERFORMANCE: The 2012 FX35 uses a 3.5-liter V6 (VQ-series) producing around 303 horsepower, paired with a 7-speed automatic transmission for strong acceleration and smooth highway passing. 2) RWD OR AWD DRIVETRAIN: Available in rear-wheel drive for a more sporty feel, or with AWD for better all-weather traction—helpful for rain and light snow climates. 3) SPORT-TUNED LUXURY FEEL: A firm, controlled suspension and responsive steering give it a more car-like driving experience than many SUVs, especially compared to comfort-first rivals. 4) PREMIUM TECH AND COMFORT OPTIONS: Many FX35 models are equipped with leather seating, a power moonroof, xenon/HID headlights, and available navigation and premium audio depending on trim and packages. 5) DISTINCTIVE STYLING AND WHEELS: Signature Infiniti exterior design cues, wide stance, and commonly equipped 18- or available larger alloy wheels contribute to its “sport crossover” identity.

Common Issues & Reliability

Owners searching “2012 Infiniti FX35 problems” and “2012 Infiniti FX35 common issues” often report a mix of typical luxury-SUV wear items and a few repeat concerns. Overall, “2012 Infiniti FX35 reliability” is generally considered solid when maintenance is kept up, but these are common areas to watch: 1) TRANSFER CASE LEAKS (AWD MODELS): Some AWD FX35 vehicles develop transfer case fluid leaks, sometimes showing up around 60,000–100,000 miles. Symptoms may include fluid spots under the vehicle or a burning gear-oil smell. Catching it early can prevent internal damage. 2) COOLANT LEAKS AND PLASTIC COMPONENT AGING: As mileage climbs (often 80,000+ miles), owners may see coolant seepage from aging hoses, clamps, or plastic tanks/neck fittings. Overheating risk makes this one worth addressing immediately if you notice a sweet smell, low coolant, or temperature fluctuations. 3) SUSPENSION AND TIRE WEAR: The FX35’s sporty alignment and heavier curb weight can accelerate tire wear, especially if alignment is off or if larger wheels/low-profile tires are fitted. Some owners also report front suspension wear items (bushings, links, or wheel bearings) becoming noticeable around 70,000–120,000 miles with clunks or vibration. 4) INTERIOR/TECH NIGGLES: Like many vehicles of this era, minor issues can pop up with power accessories, infotainment controls, or intermittent sensor warnings. These are usually more annoyance than deal-breaker, but diagnostics can add cost.
