What Problems Does the 2007 Infiniti FX45 Have?
The 2007 Infiniti FX45, while generally well-regarded for its performance and style, does have some commonly reported issues and potential long-term concerns. One of the most frequent complaints revolves around the infotainment and electronics. Owners have reported issues with the navigation system freezing or becoming unresponsive, problems with the Bose audio system speakers failing, and glitches with the climate control display. These can be costly to repair, especially the navigation unit.
Another area of concern for some FX45 owners is the fuel pump. Several reports indicate premature failure of the fuel pump, leading to stalling and the inability to start the vehicle. This is a critical component and a significant repair.
The suspension can also present issues over time. While praised for its sporty handling, the suspension components, such as bushings and struts, can wear out, leading to clunking noises, a rougher ride, and compromised handling. This is common for vehicles of this age and mileage, but replacement parts can be expensive.
While less frequent, some owners have experienced issues with the transfer case, particularly on AWD models, though this is often linked to lack of maintenance or extreme use. The V8 engine itself is generally robust, but like any high-performance engine, it requires diligent maintenance. Neglecting oil changes can lead to premature wear.
Recalls for the 2007 Infiniti FX45 are not extensive but are worth checking with a VIN lookup. Common recalls for this generation of FX models sometimes involved issues with the front passenger airbag inflator. It's crucial to ensure any outstanding recalls have been addressed by a dealership.
Regarding long-term reliability, the FX45 is a mixed bag. Its robust V8 engine and strong chassis contribute to longevity if well-maintained. However, the complexity of its electronic systems and the potential for wear on suspension components mean that ongoing maintenance costs can be significant. Model year specific issues are less pronounced for the 2007 model, as it was part of a generation that had seen some refinements. However, due to its age, checking the specific maintenance history is paramount. The biggest hurdle to long-term reliability is often the owner's commitment to a strict and comprehensive maintenance schedule.

How long will the 2007 Infiniti FX45 last?
Based on owner data and typical usage, a well-maintained 2007 Infiniti FX45 can reasonably be expected to last between 150,000 and 200,000 miles, or even more. This translates to approximately 10 to 15 years of service, assuming an average annual mileage of 12,000-15,000 miles. The V8 engine is inherently durable, but its longevity heavily depends on regular and meticulous maintenance, especially oil changes. Weaknesses over time include potential wear on suspension components, leading to a less refined ride, and the aforementioned electronic glitches in the infotainment system. While the core mechanicals can be robust, the cost of repairing aging electronics or complex suspension parts can become a significant factor in its long-term ownership viability.
What Technology & Safety Features are Included?
The 2007 Infiniti FX45 offered a respectable array of technology, entertainment, and safety features for its era, with many desirable options. Standard tech typically included a Bose premium audio system, often with a 6-disc CD changer, and dual-zone automatic climate control. The key optional technology upgrade was the navigation system, which often bundled with a rearview camera and satellite radio functionality. The Intelligent Key system with push-button ignition was also a significant convenience feature.
In terms of driver assistance, the 2007 FX45 was ahead of its time with the availability of Intelligent Cruise Control (ICC), an early form of adaptive cruise control that could maintain a set distance from the vehicle ahead. While not as sophisticated as today's systems, it was a notable feature for the period.
Safety was also a priority. Standard safety equipment included multi-stage front airbags, front side-impact airbags, and roof-mounted curtain side-impact airbags for front and rear passengers. Anti-lock Braking System (ABS) with Electronic Brake-force Distribution (EBD) and Brake Assist were also standard. The vehicle's structure was designed for rigidity, contributing to its safety in a collision.
Crash-test ratings for the 2007 Infiniti FX45 were generally good. The National Highway Traffic Safety Administration (NHTSA) awarded it four out of five stars in frontal driver and passenger crash tests. In side-impact crash tests, it also received four stars for the front passenger and four stars for the rear passenger. The Insurance Institute for Highway Safety (IIHS) gave it a good rating in their frontal offset crash tests. However, it's important to note that these ratings are from a time when testing protocols were less stringent than they are today. Nonetheless, they indicate a solid level of safety for its time. The availability of optional features like the rearview camera and ICC added further layers of safety and convenience for the driver.

How Does the 2007 Infiniti FX45 Compare to Other Sport Utility Vehicle?
The 2007 Infiniti FX45 competed in the burgeoning luxury crossover segment, facing stiff competition. Its primary rivals included vehicles like the BMW X5 (e.g., 4.8i), Lexus RX 350/400h, and the Porsche Cayenne (base models).
Performance: The FX45's V8 engine offered strong acceleration, rivaling or exceeding the base V6 models of the X5 and Cayenne, and significantly outperforming the RX 350 in raw power. Its handling was also more engaging and sportier than the comfort-oriented Lexus RX and a more accessible alternative to the sharper, but often less powerful, base Cayenne.

- For a more engaging driving experience with similar power but potentially higher maintenance: The BMW X5 4.8i offers a similar blend of performance and luxury, though often at a higher price point and with more complex maintenance.
- For the ultimate in sporty luxury SUV driving dynamics (if budget allows): The Porsche Cayenne, even a first-generation model, offers superior handling and a more driver-focused experience, but at a significant premium in purchase price and ownership costs.
- Similar Alternative: The Infiniti FX35 (V6) offers a similar stylish package and handling dynamics with much better fuel economy, though with less potent acceleration.
Final Verdict: Is the 2007 Infiniti FX45 a Good Sport Utility Vehicle?
The 2007 Infiniti FX45 is ideal for buyers who prioritize bold styling, potent V8 performance, and sporty handling in a luxury crossover package, and who are less concerned with fuel economy or the absolute lowest long-term maintenance costs. It's certainly not worth buying new today, but as a used vehicle, it offers a unique proposition. It's a strong contender for those seeking a distinctively designed SUV with more driving excitement than many rivals, particularly if they can find one with a pristine maintenance history. A thorough pre-purchase inspection is highly recommended, focusing on the engine, transmission, and electronic systems. It's a good buy for the enthusiast looking for a head-turning vehicle with punchy acceleration, provided they are prepared for potentially higher fuel and repair bills than a more mainstream or hybrid luxury SUV.
