The 1998 Infiniti QX4, based on the Nissan Pathfinder platform, is a luxury SUV that bridged the gap between rugged capability and upscale comfort. Produced from 1997 to 2003, it offered a single, well-equipped trim.

Its initial pricing ranged from approximately $35,000 to $40,000.
The Good
The 1998 QX4 excels in its robust performance with available 4WD, reliable engineering derived from the Pathfinder, and a comfortable, luxurious cabin.

The Bad

What Problems Does the 1998 Infiniti QX4 Have?
The 1998 Infiniti QX4, while generally considered reliable, does have some commonly reported issues that potential buyers should be aware of. One of the most frequently cited problems is with the automatic transmission. Specifically, the transmission valve body can develop issues, leading to rough shifting, delayed engagement, or complete failure. This can be a costly repair, often requiring a rebuild or replacement. Another area of concern for older QX4 models is the exhaust system. Due to age and exposure to elements, rust and corrosion can lead to leaks or premature failure of exhaust components, including the catalytic converter. The suspension system is another common source of wear and tear. Bushings, ball joints, and struts can degrade over time, leading to noise, poor handling, and a less comfortable ride. Interior components can also be a weak point. Power window regulators are known to fail, leaving windows stuck in place. The climate control system, including the blower motor and its resistor, can also develop problems, leading to inadequate heating or air conditioning. While specific model year recalls for the 1998 QX4 are not extensive, it's always advisable to check the National Highway Traffic Safety Administration (NHTSA) website for any applicable safety recalls that may have been issued. Long-term reliability is generally good if the vehicle has been well-maintained, but owners should anticipate some of these common repairs as the vehicle ages. Addressing these issues proactively can help maintain the QX4's dependability.
How long will the 1998 Infiniti QX4 last?
With diligent maintenance, the 1998 Infiniti QX4 can comfortably achieve 200,000 miles and beyond. Many owners report reaching or exceeding 250,000 miles, showcasing its robust build. Long-term durability is a strong suit, thanks to its solid truck-based chassis inherited from the Nissan Pathfinder. However, as highlighted in other sections, certain components like the transmission valve body, suspension parts, and exhaust system are known to require attention over time. Consistent fluid changes for the engine and transmission, along with regular inspections of the suspension and exhaust, are crucial for maximizing its lifespan and mitigating potential costly repairs. Proper care allows the QX4 to remain a dependable vehicle for many years and miles.
What Technology & Safety Features are Included?
The 1998 Infiniti QX4 offered a respectable suite of technology, entertainment, and safety features for its era, aiming to provide a premium experience. Technology and Entertainment: Standard on the 1998 QX4 was a Bose premium audio system, often featuring a multi-disc CD changer or a single-disc CD player. This system was lauded for its sound quality, a significant upgrade over many competitors. Automatic climate control was also a key feature, allowing for precise temperature management. Power windows, power door locks, and cruise control were standard amenities for convenience. Driver-Assistance Features: In terms of driver assistance, the 1998 QX4 was relatively basic by modern standards. It featured Anti-lock Braking System (ABS) as standard, which is crucial for maintaining steering control during hard braking. There were no advanced electronic stability or traction control systems available in this model year. Safety Features: Safety was addressed with standard dual front airbags for the driver and front passenger. The vehicle's robust construction, derived from a body-on-frame design, contributed to its structural integrity in a collision. Optional Features: While the QX4 was well-equipped, optional features could have included a power-operated sunroof, and in some cases, a rear-seat entertainment system, though this was less common for the 1998 model year. Crash-Test Ratings: Specific crash-test ratings for the 1998 Infiniti QX4 from organizations like the NHTSA or IIHS can be difficult to find as comprehensive data from that period is not always readily available. However, vehicles of this era with body-on-frame construction generally performed adequately in frontal and side impacts, though without the advanced crumple zones and safety structures found in modern vehicles.

How Does the 1998 Infiniti QX4 Compare to Other Vehicle?
The 1998 Infiniti QX4 competed in the luxury SUV segment against notable rivals such as the Lexus LX 450, Acura SLX (a badge-engineered Isuzu Trooper), and the Land Rover Discovery. Performance: The QX4's 168-hp V6 offered adequate performance for daily driving and modest off-roading, especially with its available AWD. The Lexus LX 450, with its Land Cruiser underpinnings, offered superior off-road capability and a more powerful V8 engine, but at a higher price. The Acura SLX, sharing the Trooper's robust chassis, also provided good off-road prowess. Features: Infiniti typically equipped the QX4 with a generous list of luxury features, including leather and a premium sound system, often matching or exceeding rivals in standard amenities for its price point. Lexus, however, was known for its meticulous build quality and refined interiors. Reliability: The QX4 generally held up well, benefiting from Nissan's Pathfinder platform. However, common issues like transmission problems could arise. The Lexus LX 450 is legendary for its bulletproof reliability, often considered the benchmark. The Acura SLX, while capable, could have more complex electrical issues inherited from its Isuzu roots. Price: The QX4 offered a compelling value proposition, often priced below its primary luxury competitors like the Lexus. Alternatives: For similar value and ruggedness, consider a well-maintained second-generation Nissan Pathfinder (without the luxury badge and price). If superior off-road capability and legendary reliability are paramount and budget allows, the **Lexus LX 450** is an excellent, albeit more expensive, choice. For a more European flavor with significant off-road capability, the **Land Rover Discovery Series II** could be an option, though its long-term reliability is often a concern. The **Toyota 4Runner** from the same era also offers significant capability and reliability, though in a less luxurious package.
Final Verdict: Is the 1998 Infiniti QX4 a Good Vehicle?
The 1998 Infiniti QX4 is ideal for buyers seeking a capable, comfortable, and relatively luxurious SUV from the late 90s that offers a good blend of on-road refinement and off-road potential, without the premium price tag of some competitors. It's certainly worth buying if you find a well-maintained example with documented service history, particularly if it has fewer than 150,000 miles. It's best purchased used, as new examples are long gone. Given that it was offered in a single, well-equipped trim, focus on condition and maintenance rather than specific trim levels. Be prepared for potential maintenance costs associated with older vehicles, especially regarding the transmission and suspension. This QX4 is a solid choice for those who value durability and a classic SUV experience over cutting-edge technology.
