About Infiniti QX4

This SUV launched in 1997 as an upscale version of the Nissan Pathfinder. The QX4 offers a relatively comfortable ride, supportive front seats, and predictable handling. The QX4 is a small vehicle in its class, with a low load capacity and limited cargo room. The 2000 model received significant upgrades, including a more powerful engine, stronger brakes, and better-placed controls. Except for the QX4’s selectable full-time 4WD system (available on the Pathfinder LE in 2001), there is no reason to buy it over the less expensive Nissan.

The Infiniti QX4 is a mid-size luxury SUV that debuted in September 1996 and is based on the Nissan Pathfinder unibody. Following the introduction of the Acura SLX and Lexus’ bigger LX 450, it was released. Infiniti’s initial foray into the SUV market was the QX4.

The Nissan Terrano Regulus, marketed in Japan as the Nissan Terrano Regulus and sold at Nissan’s JDM Nissan Bluebird Store, was also briefly available at Nissan Motor Store, the company’s luxury-oriented shop. The most noticeable distinctions between these vehicles and the Pathfinder are a more expensive interior and distinctive design. The Terrano Regulus, marketed as a luxury car, had off-road capability thanks to a low-range four-wheel-drive system and 8.3 inches (211 mm) of ground clearance.

The QX4 received its first major update in 2000 for model year 2001, with a new VQ series engine (also seen later in the G35 and FX35) raising power from a relatively modest 168 hp (125 kW) V6 engine to a 240 hp (179 kW) V6 engine. The displacement increased from 3.3 to 3.5 liters. The timing belt was replaced by a timing chain, and the ignition distributor was replaced by a single coil ignition system.

The QX4 received a redesigned exterior and interior body style, as well as a new dash with integrated analog clock, 17-inch (432 mm) alloy wheels, and xenon HID headlamps as part of the facelift. The Terrano Regulus trim package was no longer available in Japan. A QX4 with rear-wheel drive was also added (1997 through 2000 were only available in 4WD).

2002 Infiniti QX: The key addition for 2002 was cruise control, which was designed to keep a specified distance from other traffic. Nissan’s Intelligent Cruise Control was shared by the QX4 and Infiniti’s flagship Q45 sedan. The system, which makes use of laser sensors, was meant to autonomously speed or slow the QX4 in order to keep it a constant distance from automobiles ahead. A redesigned audio system, as well as audio controls for the optional leather/wood steering wheel, were also new for 2002. Optional rear-seat video entertainment systems included a VCR or DVD player.

2003 Infiniti QX: Curtain-type side airbags were included as standard equipment for the first time in 2003. 17-inch wheels, a driver-seat memory system, and a leather/woodgrain steering wheel with audio controls were included as standard equipment, which had previously been part of the Premium Package. Heated front and rear seats, as well as a videotape or DVD rear-seat entertainment system, were available as options. A power moonroof was included as standard.

The QX4 was retired in 2003, and the FX35/45 crossover SUV took its place in terms of price. The last QX4 was produced in November 2002. In 2004, the QX4 was replaced by the bigger QX56.
