The second-generation Infiniti FX, codenamed S51, launched for 2009 with even more aggressive 'bionic cheetah' styling than its predecessor. It came with two primary engine choices: the FX35 used Nissan's venerable VQ-series V6, while the FX50 introduced a powerful 390 hp 5.0L VK50VE V8. The platform was renamed QX70 starting with the 2014 model year, but the core vehicle remained the same until it was discontinued after 2017.
Collectors are drawn to the FX's dramatic design and its uncommon blend of performance and utility. The V8-powered FX50 is particularly desirable for its muscle-car soundtrack and surprising agility, offering a unique Japanese alternative to the Porsche Cayenne and BMW X6 of the era. With its rear-drive-biased AWD system and sport-tuned suspension, it drives more like a tall sports sedan than a traditional SUV.
The market for the second-gen FX is still developing, with an average sale price around $18,428 reflecting its current status as a used performance vehicle rather than a blue-chip collectible. The price spread is significant, indicating that low-mileage, well-cared-for examples, especially V8 models with the Sport package, command a substantial premium. These top-tier examples are the most likely candidates for future appreciation.
Buying Tips
- Check the dashboard for bubbling or cracking, a common and costly issue caused by sun exposure on earlier models.
- The VQ37VHR V6 is reliable but listen for timing chain noise, which can indicate failing oil gallery gaskets. The VK50VE V8 is robust but has high fuel and maintenance costs.
- Test all electronics thoroughly, including the infotainment screen, cameras, and driver aids. Infotainment system failures are common and can be expensive to fix.
- On FX50 models, inspect the large Akebono brakes for wear. Rotors and pads are more expensive to replace than on the V6 models.
- Verify the ATTESA E-TS all-wheel-drive system engages smoothly without hesitation or warning lights. While durable, repairs can be complex.
Based on 23 recent sales, prices range from $4,995 for high-mileage examples to $35,555 for well-preserved, low-mileage models.
