The 2003 Infiniti FX45, part of the FX crossover SUV lineup introduced for the 2003 model year, is a bold and distinctive vehicle. Available in trims like the FX45, it commanded a starting price around $45,000 when new. Its popularity stems from its aggressive, sporty styling, powerful V8 engine, and car-like handling, setting it apart from more utilitarian SUVs.
The Good
The FX45 boasts a potent V8 engine delivering exhilarating performance for emotional buyers, coupled with a surprisingly comfortable ride and premium interior for practical comfort.

Potential buyers should watch out for less-than-stellar fuel economy, a somewhat firm ride, and occasional electronic glitches. Rear visibility can be compromised due to its design, and maintenance costs can be higher than average for a non-luxury vehicle.

What Problems Does the 2003 Infiniti FX45 Have?
The 2003 Infiniti FX45, while generally well-regarded for its performance and luxury, does have a few commonly reported issues and long-term concerns that potential buyers should be aware of. One prevalent issue involves the ABS (Anti-lock Braking System) and VDC (Vehicle Dynamic Control) lights illuminating on the dashboard. This is often traced back to a faulty ABS wheel speed sensor or a problem with the ABS modulator. Repairing this can be costly, involving replacement of these components.
Another area of concern is the infotainment system, particularly the navigation screen. Over time, these screens can develop dead pixels, fail to respond to touch inputs, or simply stop working altogether. Replacement units can be expensive, and finding functioning used ones can be challenging.
The interior plastics and trim, while attractive when new, can become brittle and prone to cracking or fading over time, especially if exposed to prolonged sunlight. This is a cosmetic issue but can detract from the premium feel of the cabin.
Some owners have reported issues with the rear hatch struts losing their ability to hold the hatch open, requiring replacement. This is a relatively minor and inexpensive fix, but it's a common wear-and-tear item.
Regarding recalls for the 2003 model year, one notable recall involved the fuel filler neck potentially corroding, which could lead to fuel leakage. Another recall addressed a potential issue with the driver's side airbag inflator. It is crucial for potential buyers to check if these recalls have been addressed on any specific vehicle they are considering.
While the V8 engine itself is robust, like any vehicle of this age, maintenance is key. Neglected oil changes or other fluid services can lead to premature wear on engine components. Overall, the 2003 FX45 has a decent reliability record for its class and era, but the aforementioned issues are the most frequently cited by owners.

How long will the 2003 Infiniti FX45 last?
Based on owner data and typical maintenance, the 2003 Infiniti FX45 can realistically be expected to last for 150,000 to 200,000 miles or more. With diligent and consistent maintenance, particularly adhering to the manufacturer's service schedule, these vehicles demonstrate good long-term durability, especially with their robust V8 engine and solid chassis. However, as it ages, expect to encounter more frequent repairs related to wear-and-tear items such as suspension components, exhaust systems, and the aforementioned electronic issues. Weaknesses over time tend to manifest in the aging of interior materials and the increasing likelihood of electrical gremlins, rather than catastrophic mechanical failures, provided it has been reasonably well cared for.
What Technology & Safety Features are Included?
The 2003 Infiniti FX45 was positioned as a luxury crossover, and its technology, entertainment, and safety features reflected this. Standard tech typically included a Bose premium audio system with an in-dash CD player, offering good sound quality for its era. Power-adjustable front seats with driver memory and a power sunroof were also standard, enhancing convenience and comfort.
Optional technology features were key to the FX45's appeal. A prominent option was the Infiniti Navigation System, which featured a touchscreen interface and voice recognition. This was a significant technological advancement for 2003. Another popular option was a rear-seat entertainment system, typically including a DVD player and a drop-down screen, ideal for keeping passengers occupied on longer journeys.
Driver-assistance features were relatively basic by today's standards but included cruise control and remote keyless entry with an engine immobilizer. While advanced driver-assistance systems like adaptive cruise control or lane keeping assist were not available, the focus was on core functionality.
Safety was a priority, and the 2003 FX45 came equipped with a comprehensive suite of safety features. Standard equipment included front-seat airbags, front-seat side-impact airbags, and curtain side-impact airbags for front and rear occupants. It also featured four-wheel anti-lock disc brakes (ABS), traction control, and stability control (VDC). The rigid body structure was designed to protect occupants in the event of a collision.
Crash-test ratings for the 2003 model year are available from the National Highway Traffic Safety Administration (NHTSA). The FX45 generally received good ratings, with four out of five stars for the driver and front passenger in frontal crash tests and four out of five stars for side crash tests. These ratings indicate a good level of protection for occupants.

2003 Infiniti FX45 Prices and Market Value
When new, the 2003 Infiniti FX45 had a Manufacturer's Suggested Retail Price (MSRP) starting around $45,000, positioning it firmly in the luxury crossover segment. Due to its age and the general depreciation of luxury vehicles, current used market prices for a 2003 FX45 typically range from $3,000 to $7,000, depending heavily on mileage, condition, and trim level. Factors affecting its resale value include the rarity of well-maintained examples, the presence of desirable optional features like the navigation system, and the overall reputation for reliability despite its age. High mileage and evidence of poor maintenance significantly reduce its value, while a comprehensive service history can command a premium. Depreciation has been substantial, as is typical for most vehicles after two decades.
2003 Infiniti FX45 Cost of Ownership
Owning a 2003 Infiniti FX45 is generally considered more costly than owning a mainstream sedan or SUV. Insurance premiums can be higher due to its luxury classification and V8 engine. Fuel costs are significant, with its thirsty V8 averaging around 15-16 mpg combined. Maintenance, including oil changes and regular service, will align with luxury vehicle pricing. Repair costs, especially for specialized components or electronic issues, can be substantial. Therefore, the FX45 is not an economical vehicle to own long-term; it leans towards a more costly ownership experience, requiring a budget prepared for potentially higher upkeep.

How Does the 2003 Infiniti FX45 Compare to Other Sport Utility Vehicle?
The 2003 Infiniti FX45 competed in a burgeoning luxury crossover segment against rivals like the BMW X5, Mercedes-Benz ML-Class, and Lexus RX 330.
Performance: The FX45's 315-hp V8 offered superior straight-line acceleration compared to many of its competitors, particularly the standard six-cylinder offerings from BMW and Mercedes. While the X5 could rival its performance, the RX 330 was generally more comfort-oriented and less performance-driven.
Features: Infiniti equipped the FX45 generously with standard luxury features like leather, heated seats, and the Bose audio system. Optional navigation and entertainment systems were competitive. BMW often offered more advanced technology, while Lexus focused on refined comfort and a user-friendly interface.
Reliability: In terms of reliability, the Lexus RX 330 generally held the crown, known for its bulletproof mechanicals and lower long-term repair costs. The BMW X5 and Mercedes ML-Class, while offering sophisticated driving dynamics, were often more prone to expensive repairs as they aged. The FX45 falls somewhere in the middle; its V8 is robust, but it can suffer from specific electronic and ABS issues.
Price: When new, all these vehicles were similarly priced in the luxury segment. In the used market, the FX45 often presents a compelling value proposition for its performance and style, typically being more affordable than comparable BMW or Mercedes models. The RX 330 might retain its value better due to its stellar reliability reputation.

Alternatives:
- For ultimate reliability and comfort: The Lexus RX 330 is a strong contender, offering a smoother ride and generally lower ownership costs.
- For driving dynamics and sportiness: The BMW X5 (E53 generation), especially with a V8 engine, can offer a more engaging driving experience, though at the risk of higher maintenance bills.
- For a more utilitarian luxury option: The Acura MDX (first generation) offers a more spacious interior and Honda's reputation for reliability, though it lacks the V8 punch of the FX45.
Final Verdict: Is the 2003 Infiniti FX45 a Good Sport Utility Vehicle?
The 2003 Infiniti FX45 is ideal for buyers who prioritize bold styling and V8 performance in a luxury crossover package and are not deterred by potentially higher running costs. It's worth buying if you can find a well-maintained example with a thorough service history, as its unique character and power offer significant bang for the buck on the used market. New purchases are obviously not applicable. Focusing on the FX45 trim is essential as it represents the peak of its offerings. Buyers should be prepared for above-average fuel consumption and potential repairs related to its age and electronic systems. It's a purchase for someone who appreciates its distinctive qualities and is willing to invest in its upkeep.
