The 2004 Infiniti FX45 is a bold and stylish luxury crossover SUV that debuted for the 2003 model year. Slotting between the smaller FX35 and larger QX56, the FX45 was a premium offering. Its model years spanned from 2003 to 2008, with the 2004 model being a significant iteration. The primary trim was the FX45, powered by a potent V8 engine. What truly made the FX45 stand out was its aggressive, sports-car-inspired styling, unique rear-wheel-drive bias, and a powerful V8 engine, making it a distinctive choice in the luxury SUV segment.
The Good
The 2004 FX45 boasts a potent V8 engine for thrilling acceleration (emotional appeal), a surprisingly athletic chassis for engaging handling, and a distinctive, head-turning design. Its comfortable interior offers a premium feel, while its relative rarity adds to its desirability for those seeking something unique. Practical buyers will appreciate its robust build quality and the luxury experience it provides.
The Bad
Potential buyers of the 2004 Infiniti FX45 should be aware of its thirsty V8 engine, leading to poor fuel economy. Rear visibility can be limited due to its design, and some interior materials may show wear over time. Suspension components and electronic systems can also be sources of concern in older models.

What Problems Does the 2004 Infiniti FX45 Have?
The 2004 Infiniti FX45, while generally well-regarded for its performance and style, does have some common issues that owners report over time. One frequently cited concern revolves around the infotainment and electronic systems. Issues such as malfunctioning navigation screens, faulty climate control displays, and intermittent problems with the audio system can arise, particularly as the vehicle ages. These can be costly to repair due to the specialized nature of the components. Another area to watch is the suspension and steering components. Worn ball joints, tie rod ends, and strut mounts can lead to clunking noises, imprecise handling, and uneven tire wear. Given the FX45's sporty nature, these components are often subjected to more stress. The exhaust system is also known to develop leaks or rust over time, especially in areas with harsh winters and road salt exposure. While the V8 engine is generally robust, some owners have reported issues with oil leaks from the valve covers or oil pan. There are no widespread, model-year-specific recalls that stand out as a major red flag for the 2004 model, but routine maintenance is crucial. Long-term reliability can be good if well-maintained, but potential buyers should be prepared for potential repairs on aging electronics and suspension parts. Checking for a detailed maintenance history is highly recommended when considering a used FX45. While not a universal problem, some reports indicate potential issues with the fuel level sensor, leading to inaccurate gauge readings.
How long will the 2004 Infiniti FX45 last?
Based on owner data and typical maintenance habits, the 2004 Infiniti FX45 can realistically achieve between 150,000 to 200,000 miles or more in terms of its service life. With diligent and regular maintenance, including timely oil changes, fluid flushes, and addressing minor issues promptly, this V8-powered crossover demonstrates good long-term durability. The core powertrain is generally robust. However, weaknesses tend to emerge in its aging electronic components and suspension parts, as mentioned previously. Neglecting maintenance, especially for the drivetrain and suspension, can significantly shorten its effective service life. Owners who prioritize preventative care can expect a vehicle that holds up well, offering continued performance and luxury for many years.
What Technology & Safety Features are Included?
The 2004 Infiniti FX45 offered a respectable suite of technology and safety features for its era, blending luxury with convenience. Standard tech and entertainment typically included a high-quality Bose audio system with a CD player, often with steering wheel-mounted controls. The climate control system was dual-zone automatic, providing individualized comfort. For safety, the FX45 came equipped with standard front and side-impact airbags for the front occupants, as well as **roof-mounted side curtain airbags** for both rows, enhancing overall occupant protection. Anti-lock brakes (ABS) were standard, contributing to improved stopping power.
Optional features significantly enhanced the tech experience. A popular option was the DVD-based navigation system, which also often integrated with a rear-view camera. This was a cutting-edge feature for its time, aiding in parking and maneuvering. Some models could also be equipped with a rear-seat entertainment system, complete with a screen and headphones, making longer journeys more enjoyable for passengers. While advanced driver-assistance systems as we know them today were not prevalent, features like cruise control were standard.
In terms of crash-test ratings, the 2004 Infiniti FX series generally performed well. The National Highway Traffic Safety Administration (NHTSA) awarded the FX series with four out of five stars in frontal driver and passenger crash tests. Side-impact crash tests also yielded good results. These ratings underscored the vehicle's robust construction and commitment to occupant safety. The combination of standard and optional features made the FX45 a well-equipped luxury crossover for its time.

2004 Infiniti FX45 Prices and Market Value
When new, the 2004 Infiniti FX45 had a Manufacturer's Suggested Retail Price (MSRP) that typically started in the high $40,000s, positioning it firmly in the premium luxury SUV segment. Today, its used market prices vary significantly based on condition, mileage, and location, but you can often find them ranging from $5,000 to $12,000. The FX45 experienced a moderate to steep depreciation curve, as is common with most luxury vehicles. Factors affecting its resale value include its distinct styling (which can be polarizing), its V8 engine's fuel consumption, and the potential for higher maintenance costs on older luxury vehicles. Well-maintained examples with lower mileage and desirable options will command higher prices.
2004 Infiniti FX45 Cost of Ownership
Owning a 2004 Infiniti FX45 is generally considered costly rather than economical. Insurance premiums will likely be higher than average due to its luxury status and performance. The V8 engine is a significant factor in fuel costs, with owners reporting low MPG figures that result in substantial spending at the pump. Maintenance costs are also elevated, as parts and labor for luxury vehicles are typically more expensive. Repairs, especially for specialized electronic components or suspension issues, can be particularly high. While a rewarding vehicle to drive, the long-term ownership costs of the FX45 should be carefully considered by prospective buyers.

How Does the 2004 Infiniti FX45 Compare to Other Sport Utility Vehicle?
The 2004 Infiniti FX45 competed in a niche segment of luxury crossovers that prioritized performance and style. Its key rivals included vehicles like the BMW X5 4.4i, the Porsche Cayenne (though often more expensive), and to some extent, the Lexus RX 330 (which was more comfort-oriented).
Performance: The FX45's V8 engine and rear-wheel-drive bias gave it a distinct advantage in driving dynamics over many rivals, particularly the more comfort-focused Lexus RX. It offered a sportier, more engaging driving experience than the typical luxury SUV of its time. The BMW X5 4.4i offered comparable or even superior performance, while the Porsche Cayenne was a performance benchmark but at a significantly higher price point.
Features: The FX45 was well-equipped for its price, offering a good mix of luxury and technology. However, rivals like the BMW X5 often offered more sophisticated optional features and a more extensive driver-assistance suite. The Lexus RX 330 prioritized comfort and refinement, excelling in interior quietness and ride quality.
Reliability: This is where the FX45 can be a mixed bag. While its core mechanicals are robust, like many luxury vehicles of this era, it can be prone to costly electronic and suspension issues as it ages. The BMW X5 also has a reputation for higher maintenance and repair costs. The Lexus RX 330 is generally considered more reliable and less expensive to maintain in the long run, making it a more practical choice for budget-conscious buyers.
Price: The FX45 offered a compelling value proposition, providing V8 power and sporty styling at a price point often lower than comparable German rivals when new. On the used market, it remains a relatively affordable way to get into a V8-powered luxury crossover.
Alternatives: If performance and a distinctive style are paramount, the FX45 is a strong contender. However, if long-term reliability and lower running costs are higher priorities, a well-maintained Lexus RX 330 would be a more sensible choice. For those seeking ultimate driving dynamics and willing to accept higher maintenance, a used BMW X5 4.4i is a comparable alternative. The Acura MDX also offered a good blend of performance and reliability in this segment.

It's a vehicle for those who appreciate a less conventional, sportier approach to the SUV segment and are willing to accept the associated fuel and potential maintenance costs.
