2012-2013 Infiniti JX 35 V6 (265 Hp) 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 Lexus RX. The vehicle was built on an extended version of the Nissan D platform, shared with the Nissan Pathfinder, but with Infiniti-specific styling and a more premium interior. This particular variant, equipped with the 3.5-liter V6 engine paired with a Continuously Variable Transmission (CVT), was the sole powertrain offering for the JX35 during its brief production run. It was designed to provide a balance of performance, fuel efficiency, and a smooth driving experience for families.

Powertrain & Engine Architecture

The heart of the JX35 is Nissan’s VQ35DE 3.5-liter V6 engine. This engine, a member of the highly regarded VQ family, is known for its smooth operation and reliability. It 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. The VQ35DE utilizes multi-port fuel injection and a compression ratio of 10.3:1. The engine produces 265 horsepower at 6400 rpm and 247.82 lb-ft of torque at 4400 rpm. Paired exclusively with the engine is a Continuously Variable Transmission (CVT). Nissan’s Xtronic CVT, as it was branded, aimed to provide seamless acceleration and improved fuel economy compared to traditional automatic transmissions. The CVT lacks fixed gear ratios, instead using a belt and pulley system to provide an infinite number of ratios within its operating range.

Driving Characteristics

The JX35 3.5L/CVT combination delivers adequate, though not particularly exhilarating, performance. The CVT effectively utilizes the engine’s torque, providing smooth and linear acceleration. However, the lack of distinct gear changes can feel somewhat disconnected to drivers accustomed to traditional automatics. The JX35 is not a sporty vehicle; its focus is on comfort and ease of driving. Compared to a hypothetical manual transmission version (which was never offered), the CVT prioritizes fuel efficiency and smoothness over outright acceleration. The CVT’s programming is tuned for relaxed cruising and responsive passing maneuvers, but it can sometimes exhibit “rubber band” effect under hard acceleration, where engine RPMs rise quickly without a corresponding increase in vehicle speed. The front-wheel-drive configuration contributes to decent fuel economy but limits traction in adverse weather conditions.

Equipment & Trim Levels

The JX35 was offered with a relatively generous level of standard equipment. Base models included tri-zone automatic climate control, leather upholstery, power-adjustable front seats, a rearview camera, Bluetooth connectivity, and a Bose audio system. Optional extras 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 varied, with options for woodgrain accents and different leather color combinations. The JX35 aimed for a premium feel, with soft-touch materials and a well-designed dashboard layout. The third-row seats were relatively accessible and offered reasonable space for children or smaller adults.

Chassis & Braking

The JX35 utilizes an independent suspension system at all four wheels. The front suspension employs a McPherson strut design with coil springs and an anti-roll bar, while the rear features a multi-link setup with a stabilizer bar. This suspension configuration prioritizes ride comfort and stability. 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. Steering is rack-and-pinion with electric power assist, offering light and precise steering feel. The vehicle’s relatively high curb weight (approximately 4279 lbs) contributes to a stable and planted feel on the road.

Market Reception & Comparison

The Infiniti JX35 was generally well-received by automotive critics. It was praised for its spacious interior, comfortable ride, and user-friendly technology. However, some reviewers noted that the CVT could feel unrefined at times and that the JX35 lacked the sporty driving dynamics of some of its competitors. Compared to the Acura MDX, the JX35 offered a more competitive price point but lacked the MDX’s more engaging driving experience. Against the Lexus RX, the JX35 provided more interior space and a slightly more modern design, but the RX was known for its exceptional reliability and resale value. Fuel economy figures of 21 mpg combined were competitive for the segment, but not class-leading.

Legacy

The Infiniti JX35 was a short-lived model, replaced by the QX60 for the 2014 model year. However, the JX35 laid the groundwork for Infiniti’s successful expansion into the three-row luxury crossover market. The VQ35DE engine and Xtronic CVT transmission have proven to be relatively reliable, although regular maintenance is crucial. On the used car market, the JX35 represents a good value for buyers seeking a spacious and comfortable family vehicle. Common issues reported by owners include minor electrical glitches and occasional CVT wear, but these are generally not major concerns if the vehicle has been well-maintained. The JX35 remains a practical and affordable option for those needing a seven-passenger crossover.
