2012-2013 Infiniti JX 35 V6 (265 Hp) AWD CVT

The Infiniti JX35, produced for the 2013 model year (with initial production beginning in February 2012), represented Infiniti’s entry into the burgeoning three-row luxury crossover segment. Positioned as a more practical and family-oriented alternative to the smaller EX and FX models, the JX35 aimed to compete with established players like the Acura MDX and Buick Enclave. This particular variant, equipped with the 3.5-liter V6 engine producing 265 horsepower and paired with a Continuously Variable Transmission (CVT) and all-wheel drive (AWD), was the sole powertrain offering for the JX35 during its brief production run. The JX was later replaced by the QX60 in 2014, receiving significant styling and feature updates.

Powertrain & Engine Architecture

The heart of the JX35 is Nissan’s venerable VQ35DE 3.5-liter V6 engine. This engine, a member of the highly-regarded VQ family, is known for its smoothness, reliability, and respectable power output. The VQ35DE features a 60-degree V-angle, aluminum alloy block and cylinder heads, and dual overhead camshafts (DOHC) with Continuously Variable Valve Timing Control System (CVTCS) on both intake and exhaust valves. This system optimizes valve timing for improved performance and fuel efficiency across the engine’s operating range. Fuel delivery is handled by a multi-port fuel injection system. The engine produces 265 horsepower at 6400 rpm and 247.82 lb-ft of torque at 4400 rpm.

The engine is mated to a Jatco-sourced Continuously Variable Transmission (CVT). Unlike traditional automatic transmissions with fixed gear ratios, a CVT utilizes a belt and pulley system to provide an infinite number of gear ratios within its operating range. This allows the engine to operate at its most efficient rpm for any given speed and load, contributing to improved fuel economy. The AWD system employs an electromagnetic clutch to seamlessly engage the rear wheels when traction is needed, enhancing stability in adverse weather conditions.

Driving Characteristics

The JX35 3.5L AWD CVT delivers adequate, though not exhilarating, performance. The CVT, while contributing to fuel efficiency, can sometimes feel less responsive than a traditional automatic transmission, exhibiting a “rubber band” effect during hard acceleration. The 265 horsepower is sufficient for everyday driving and highway merging, but the JX35 doesn’t feel particularly quick. The CVT is programmed to mimic stepped gears under heavy acceleration, attempting to provide a more conventional driving experience. The AWD system provides confident handling in slippery conditions, but the JX35 is primarily geared towards comfort and practicality rather than sporty driving dynamics.

Equipment & Trim Levels

The JX35 came standard with a generous array of features, including tri-zone automatic climate control, leather upholstery, power-adjustable front seats, a rearview camera, and a Bose audio system. Available options included a navigation system, a dual-screen rear entertainment system, and advanced safety features like blind-spot monitoring and lane departure warning. Interior trim levels were relatively simple, with options for wood or metallic accents. The third-row seats were relatively easy to access and offered reasonable space for children or smaller adults.

Chassis & Braking

The JX35 utilizes an independent McPherson strut suspension in the front and an independent multi-link suspension in the rear. This setup provides a comfortable ride, effectively absorbing bumps and road imperfections. Stabilizer bars are fitted to both axles to reduce body roll during cornering. Braking duties are handled by ventilated discs on all four wheels, providing adequate stopping power. The JX35 is equipped with an Anti-lock Braking System (ABS) as standard equipment.

Market Reception & Comparison

Critics generally praised the JX35 for its spacious interior, comfortable ride, and user-friendly technology. However, some reviewers found the CVT to be less engaging than traditional automatic transmissions, and the overall driving experience lacked the sportiness of some competitors. Fuel economy was considered average for the segment. Compared to the base V6 Acura MDX, the JX35 offered a slightly lower price point and a more luxurious interior, but the MDX provided a more engaging driving experience. The JX35’s reliability was generally good, though some owners reported minor issues with the CVT.

Legacy

The Infiniti JX35, despite its short production run, established Infiniti as a viable contender in the three-row luxury crossover market. The VQ35DE engine proved to be a durable and reliable powerplant, and the CVT, while not universally loved, contributed to reasonable fuel economy. On the used car market, the JX35 represents a relatively affordable option for families seeking a spacious and well-equipped crossover. Maintenance costs are generally reasonable, and parts availability is good. However, potential buyers should be aware of the potential for CVT issues and ensure that the transmission has been properly maintained.
