The 2006 Infiniti FX45 is a luxury crossover SUV that debuted in 2003 as a 2004 model year. Built on a rear-wheel-drive platform shared with the Nissan 350Z, it offers a distinctive blend of sports car performance and SUV utility. Key trims primarily revolve around the FX45 designation. Originally priced in the mid-to-high $40,000s, its popularity stems from its bold, aggressive styling and powerful V8 engine, setting it apart from more conservative luxury SUVs.

What Problems Does the 2006 Infiniti FX45 Have?
The 2006 Infiniti FX45, while generally considered a robust vehicle, does have some reported issues that potential buyers should be aware of. One of the more common complaints revolves around the infotainment system and its associated electronics. Owners have reported issues with the navigation system freezing or malfunctioning, as well as problems with the audio system and Bluetooth connectivity (if equipped). The climate control system, particularly the blower motor and its resistor, can also be a source of trouble, leading to intermittent or non-functional heating and air conditioning.
Another area of concern for some FX45 owners is related to the suspension. Worn bushings, ball joints, and tie rods can lead to noise, imprecise handling, and premature tire wear. The power steering system has also been cited for occasional leaks or stiffness. Given the vehicle's performance-oriented nature, brake components may also require more frequent replacement than in a typical crossover.
While there haven't been widespread, catastrophic mechanical failures frequently reported across all 2006 models, specific to the FX45 generation (which spanned from 2003-2008), some owners have experienced issues with the fuel pump and its associated sensors. Premature wear on the exhaust system components has also been noted. Regarding recalls for the 2006 model year, some vehicles may have been subject to recalls related to potential issues with the airbag system or fuel tank filler neck, though these would have been addressed by now if a vehicle was properly maintained.
Long-term reliability can be impacted by the vehicle's more performance-oriented design. Drivers who push the vehicle hard may experience faster wear on components like tires, brakes, and suspension parts. However, with regular and diligent maintenance, many FX45 models continue to serve their owners well into higher mileage.

How long will the 2006 Infiniti FX45 last?
Based on owner data and typical maintenance habits, a well-maintained 2006 Infiniti FX45 can reasonably be expected to reach 150,000 to 200,000 miles or more. Its V8 engine is generally robust and capable of extended service life. Long-term durability is significantly influenced by proactive maintenance, particularly regular fluid changes (engine oil, transmission fluid, coolant) and addressing minor issues promptly. Weaknesses that tend to appear over time include potential wear in the suspension components, such as bushings and ball joints, and the aforementioned electronic gremlins within the infotainment and climate control systems. Rust can also be a concern in areas with harsh winters if the undercarriage isn't regularly cleaned and protected.
What Technology & Safety Features are Included?
The 2006 Infiniti FX45 offered a respectable array of technology, entertainment, and safety features for its era, blending luxury with practicality. Standard tech highlights often included automatic climate control, power-adjustable and heated front seats, a power moonroof, and a premium Bose audio system, typically with an in-dash 6-disc CD changer and SiriusXM satellite radio capability.
Entertainment options could be enhanced with an optional DVD-based navigation system, which also often integrated a rearview camera for improved parking assistance. This system was a significant tech upgrade at the time, providing real-time traffic updates and voice recognition. Intelligent Key keyless entry and push-button start were also standard, adding a touch of modern convenience.
In terms of driver-assistance features, the FX45 was ahead of many competitors with its available adaptive cruise control, which could maintain a set distance from the vehicle ahead. This system was part of a more comprehensive technology package that sometimes included features like lane departure warning (though less common and less sophisticated than today's systems).
Safety was a priority for Infiniti. Standard safety features included front-seat airbags, front-side impact airbags, and roof-mounted curtain airbags for front and rear occupants. Anti-lock brakes (ABS) with electronic brake force distribution (EBD) and brake assist were also standard, designed to improve stopping performance. Traction control and stability control systems (Vehicle Dynamic Control) were also typically included to help the driver maintain control in slippery conditions.
Crash-test ratings for the 2006 Infiniti FX45, while specific ratings from organizations like the NHTSA or IIHS for this exact model year can be hard to pinpoint as they evolved, generally reflected good performance for its class. Early indications and reviews suggested solid structural integrity. The combination of advanced safety features and a sturdy chassis contributed to a secure cabin environment.

How Does the 2006 Infiniti FX45 Compare to Other Sport Utility Vehicle?
The 2006 Infiniti FX45 occupied a unique niche, blending performance and style. Its closest rivals often included the BMW X5, Lexus RX 330 (later RX 350), and the Porsche Cayenne.
Performance: The FX45's 315-horsepower V8 offered superior acceleration and a more engaging driving experience compared to the more comfort-oriented Lexus RX 330. The BMW X5, particularly with its optional V8, could rival or surpass the FX45's performance, while the Porsche Cayenne, especially in its more potent variants, was in a league of its own for outright speed and handling prowess, but at a significantly higher price.
Features: At this price point, the FX45 was well-equipped with luxury amenities like leather, heated seats, and a premium sound system. The BMW X5 often offered more advanced technological features and a wider array of optional performance packages. The Lexus RX 330 was known for its exceptional build quality, quiet cabin, and user-friendly technology, though it lacked the FX45's sporty edge.
Reliability: The Lexus RX series historically boasts excellent reliability, often surpassing both the Infiniti FX and the European rivals like BMW and Porsche. While the FX45's V8 is generally robust, potential buyers should be aware of the reported electronic and suspension issues mentioned previously. The BMW X5 and Porsche Cayenne, while offering thrilling performance, can be more expensive to maintain and repair in the long run, with a higher propensity for complex mechanical and electrical issues.
Price: The FX45 generally offered a more compelling performance-per-dollar value compared to the BMW X5 and especially the Porsche Cayenne when new. In the used market, this trend often continues, making the FX45 an attractive option for those seeking V8 power and distinctive styling without the premium price tag of its German counterparts. However, the Lexus RX series often holds its value well and can be a safer bet for long-term, lower-cost ownership.
Alternatives:
Similar: 2006 BMW X5 4.4i (for performance-oriented luxury SUV).
Better (if reliability is paramount): 2006 Lexus RX 330/350 (for a more comfortable, reliable, and efficient luxury SUV).
Higher Performance/Price: 2006 Porsche Cayenne S (if budget allows for ultimate performance and luxury.

Final Verdict: Is the 2006 Infiniti FX45 a Good Sport Utility Vehicle?
The 2006 Infiniti FX45 is ideal for drivers who prioritize bold styling and potent V8 performance in a luxury crossover package and are willing to accept slightly higher running costs. It's perfect for those who want a vehicle that stands out from the crowd and offers an engaging driving experience, rather than prioritizing maximum cargo space or fuel efficiency. While buying new would have been a statement, it's now best considered on the used market.
It is worth buying for the right individual, particularly if found in good condition with a well-documented maintenance history. Opting for the FX45 trim is the only engine option for this year. Potential buyers should thoroughly inspect for common issues like suspension wear and electronic glitches. If you're a mechanically inclined individual or have a trusted mechanic familiar with Infinitis, and you value performance and distinctive design over absolute practicality, the FX45 can be a rewarding purchase.
