What Problems Does the 2002 Infiniti QX4 Have?
The 2002 Infiniti QX4, while generally considered a reliable luxury SUV, does have some frequently reported issues and areas of concern for potential buyers. One of the most commonly cited problems revolves around the transmission. Many owners have reported premature failure or significant wear and tear on the automatic transmission, especially as the vehicle approaches or exceeds 100,000 miles. This can manifest as slipping gears, harsh shifting, or a complete loss of drive. Regular transmission fluid changes and maintenance are crucial to mitigate this.
Another area to watch is the power window regulators, which can become weak or fail, leading to windows that are difficult to raise or lower. The electronic climate control (ECC) system is also known to have its quirks; issues with the blend door actuators can result in uneven heating or cooling within the cabin, or a complete failure of the system to regulate temperature.
Regarding recalls, while specific to model year, owners should always check the NHTSA website for any outstanding safety recalls. For the 2002 model year, recalls might have been issued for various components, but significant widespread, model-defining recalls are less common compared to some other vehicles.
Long-term reliability concerns often center on the wear and tear of interior components. The leather upholstery can show signs of aging, and plastic trim pieces, particularly in high-traffic areas, may become brittle or scratched over time. The exhaust system can also be a point of concern, with potential for rust or leaks, especially in regions with harsh winters. Despite these issues, many owners find the QX4 to be a durable vehicle if properly maintained, with its robust 3.5-liter V6 engine being a strong point. Addressing minor issues proactively can help extend its lifespan considerably.

Addressing minor issues proactively can help extend its lifespan considerably.
How long will the 2002 Infiniti QX4 last?
Based on owner data and anecdotal evidence, the 2002 Infiniti QX4 is capable of achieving an average of 150,000 to 200,000 miles, and even exceeding 250,000 miles with diligent maintenance. The longevity of this SUV hinges significantly on the owner's commitment to regular servicing, especially for the transmission and drivetrain components. The robust V6 engine is a testament to its long-term durability. However, without consistent fluid changes and attention to potential early warning signs, weaknesses like transmission failures and issues with electronic climate control can significantly shorten its service life. Rust, particularly on the undercarriage and exhaust system in rust-belt regions, can also be a factor in its long-term viability.
What Technology & Safety Features are Included?
The 2002 Infiniti QX4 offered a respectable suite of technology, entertainment, and safety features for its era, reflecting its position as a luxury SUV. Standard entertainment typically included a premium Bose audio system with a single-disc CD player. Higher trims or optional packages could further enhance this with a navigation system, which was a significant tech feature at the time, offering guidance on a color screen.
In terms of driver-assistance features, the 2002 QX4 was relatively basic by modern standards. It generally lacked advanced electronic aids like adaptive cruise control or lane departure warnings. However, available features often included a rearview camera (especially on later models or as an option) and parking assist sensors, which were considered cutting-edge for the time. Cruise control was standard.
Safety features were a strong point. The QX4 came equipped with standard front-seat airbags and available side-impact airbags for enhanced occupant protection. Anti-lock braking system (ABS) was standard, providing improved stopping power and control in emergency situations. Traction control was also available, particularly on the all-wheel-drive models, to help maintain stability on slippery surfaces. A robust body structure contributed to its crashworthiness.
Crash-test ratings for the 2002 Infiniti QX4, as with many vehicles from this period, can be found through organizations like the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS). Generally, SUVs of this generation performed reasonably well, with the QX4 typically receiving good ratings in frontal and side-impact crash tests. For instance, NHTSA ratings often showed good performance in frontal and side impacts for both the driver and front passenger. Owners should consult the respective safety organizations' archives for the most detailed and specific crash-test data for this model year.

2002 Infiniti QX4 Prices and Market Value
When new, the 2002 Infiniti QX4 had an original MSRP ranging from approximately $36,000 for the base rear-wheel-drive model to over $42,000 for a fully equipped all-wheel-drive Limited Edition. Like most vehicles, the QX4 experienced significant depreciation in its early years. Currently, the used market prices for a 2002 QX4 vary widely based on mileage, condition, trim level, and geographic location. You can typically find these SUVs ranging from $2,500 to $7,000. Factors significantly affecting resale value include maintenance history, the presence of rust (especially in colder climates), and the overall condition of the interior and exterior. Models with lower mileage, comprehensive service records, and in excellent cosmetic condition will command higher prices.
2002 Infiniti QX4 Cost of Ownership
Owning a 2002 Infiniti QX4 can be moderately costly. Insurance rates will likely be higher than for a non-luxury or smaller vehicle, reflecting its premium brand status and potential repair costs. Fuel costs are also a consideration due to its V6 engine and all-wheel-drive option, averaging around 13-17 mpg combined. Maintenance costs are typical for a luxury SUV; regular oil changes, tire rotations, and fluid checks are essential. However, repairs can be more expensive due to the use of premium parts and potentially more complex systems. Potential buyers should budget for possible transmission repairs, which can be a significant expense.

How Does the 2002 Infiniti QX4 Compare to Other Sport Utility Vehicle?
The 2002 Infiniti QX4 competed in the luxury mid-size SUV segment against strong rivals such as the Lexus RX 300/330, Acura MDX, and the Volvo XC90. In terms of performance, the QX4's 240-horsepower V6 offered robust acceleration and adequate towing capability, often matching or slightly exceeding the RX 300 but generally falling short of the more powerful offerings that emerged later in the segment.
Features-wise, the QX4 was well-equipped for its time, boasting leather upholstery, premium audio, and available navigation. However, rivals like the Volvo XC90 often offered more advanced safety features and a more contemporary interior design. The Lexus RX series was renowned for its smooth ride and refined interior, often perceived as more luxurious.
Reliability is where the QX4 can be a mixed bag. While the engine is generally robust, the transmission has been a known weak point, an area where the Lexus RX series historically excelled with superior drivetrain reliability. Acura also had a strong reputation for dependability. The QX4's reliability is often seen as good, but potentially less stellar than its Japanese luxury counterparts in specific critical areas.
Regarding price, the QX4 was generally positioned as a slightly more affordable entry point into the luxury SUV market compared to some of its direct competitors when new, and this trend often continues on the used market.

Alternatives to consider include:
- Lexus RX 300/330 (2000-2008): Often a superior choice for reliability, comfort, and a more refined driving experience. If ultimate dependability is the priority, the RX is hard to beat.
- Acura MDX (2001-2006): Offers a sportier driving feel and often better handling than the QX4, with a solid reputation for reliability.
- Volvo XC90 (2003-2014): If safety is paramount, the XC90 is a standout, though it might be slightly more expensive and less powerful than the QX4 in earlier years.
Final Verdict: Is the 2002 Infiniti QX4 a Good Sport Utility Vehicle?
The 2002 Infiniti QX4 is ideal for budget-conscious buyers seeking a comfortable, capable, and relatively luxurious SUV that offers a smoother ride than many truck-based alternatives. It's a good fit for individuals or small families who prioritize a refined interior and a capable V6 engine for daily driving and occasional light off-roading or towing. It is worth buying, but strictly as a used vehicle. Buying new in 2002 would have been a different proposition. When considering a purchase, prioritize models with impeccable maintenance records, especially those showing regular transmission fluid changes. The all-wheel-drive (AWD) variant is recommended for those living in areas with inclement weather. Avoid high-mileage examples with a history of transmission issues. If a well-maintained unit can be found at a reasonable price, it can still offer good value.
