The Infiniti QX70, formerly called the Infiniti FX until 2013, is a compact luxury crossover SUV produced by the Nissan-owned Infiniti luxury vehicle brand between 2002 and 2017. The FX replaced the QX4 as Infiniti's mid-size SUV. It shares the same FM platform as the rear-wheel drive Nissan 370Z, and it "made no claims of climbing mountains." Rather, its aggressive shape promised style and quick handling. The similarly sized Nissan Murano is based on the same D platform as the front-wheel drive Nissan Altima. The FX does not have a Nissan-branded equivalent and is not sold in Japan.

The FX introduced its second generation for the 2009 model year as the FX35 and FX50.

First generation (S50; 2003)

The nameplates FX35 and FX45 refer to the two available engines. The FX35 is available in two drivetrains, the RWD and the AWD, which are both fitted to a dual overhead cam 3.5-liter 24-valve V6 VQ35DE gasoline engine, with aluminum-alloy block and heads, electronically controlled throttle system, and low-friction molybdenum-coated pistons that makes use of the continuous variable valve timing which in part optimizes the opening of intake valves. This is also coupled with an electronically controlled super-wide ratio five-speed automatic with a manumatic shift mode that includes the option of sequentially selected manual gearshifts and downshift rev-matching.

The AWD FX45 incorporates a 4.5 L (4,494 cc) 32-valve V8 DOHC VK45DE gasoline engine with four valves per cylinder, microfinished camshafts with aluminum-alloy block and heads, low-friction molybdenum-coated pistons, titanium intake and exhaust valves, modular cylinder heads, microfinished crankshaft, lightweight pistons, super-silent single stage cam drive chain, and a Continuously Variable Valve Timing Control System that optimizes opening of intake valves. Development began in 1999 under newly appointed CEO Carlos Ghosn's NRP. Design work was completed in rapid succession in 2000, for late 2002 production. Designed prior to that, earlier on in 2000 under the "Bionic Cheetah" theme, the 2001 Infiniti FX45 Concept was introduced at the NAIAS in January 2001. From mid-2001, a new concept based on the production design was developed and completed in late 2001. Sketches were first released in late November 2001. The second-generation 2002 FX45 Concept was introduced in January 2002 at the NAIAS '02 as a thinly-veiled production FX (S50) and planned production was announced for early 2003. In January 2003, the 2003 FX45 made its debut at the 2003 NAIAS and went on sale January 24, 2003.

In 2003 for the 2004 model, changes were the addition of a standard eight-way power front passenger seat that replaced the previous four-way design, the availability of aluminum roof rails and chrome-plated 20-inch wheels. Also new were a dark silver metallic finish for the 20-inch wheels (non-chrome-plated), the addition of a standard HVAC filter for all models and the addition of a new Snow-Mode function.

In September 2004 for the 2005 model year, the FX range received enhancements such as a lane departure warning (LDW) system that helps alert drivers to an unintended movement of the vehicle out of a designated traffic lane. Infiniti's system monitored the lane markings to alert passengers via an audible buzzer that the driver is drifting unintentionally. The LDW system, which utilizes a small camera, speed sensor, an indicator, and an audible warning buzzer, was offered on models. The 2005 Infiniti FX was the first passenger vehicle to offer a lane departure warning system in the United States market. In addition to LDW, the 2005 Infiniti FX range was now equipped with standard roof-mounted curtain supplemental curtain airbags with rollover protection for front and rear outboard seat occupants.

Other changes included the addition of a dark chrome grille, headlight, and clear taillight accents to the FX45 (also available as part of the V6 Sport Package on FX35 models), a new key fob design for the Infiniti Intelligent Key system, and two new exterior colors, Sapphire and Sheer Platinum. Interior changes included a new standard etched aluminum trim.

Total 2007 sales of the FX45 were 1,598 units, about a tenth of the FX35s.

Common 2006 Infiniti Fx35 problems

The Infiniti FX35, a luxury SUV produced by Nissan's luxury division, has gained popularity since its introduction in 2003. While it offers impressive performance and handling, it is not without its share of common problems, especially in the 2006 model year. Here are some of the most frequently reported issues by FX35 owners:

Wheel Bearing Failure: The FX35 is known for its weak wheel bearings, which can wear out prematurely. This issue can lead to noise, vibration, and, in some cases, affect the vehicle's handling and safety. Replacing the wheel bearings is the only solution to this problem.
Timing Chain Rattle and Tapping Noise: Some FX35 owners have reported a timing chain rattle or tapping noise, which can be caused by a loose timing chain or worn-out guides. This issue may require replacing the timing chain and guides to resolve it.

Fuel Filler Hose Cracks and Leaks: The fuel filler hose on the FX35 can crack and leak, especially when refueling. This problem can lead to fuel leaks and potential fire hazards. Regular inspections and replacement of the fuel filler hose can help prevent this issue.

Erratic or High Idle: The FX35 can experience erratic or high idle, which can be caused by various factors, including vacuum leaks, faulty throttle position sensors, or issues with the idle control system. Diagnosing and addressing the root cause is essential to resolving this problem.

Fuel Gauge and Tire Pressure Sensor Issues: The fuel gauge and tire pressure sensors in the FX35 can malfunction, leading to inaccurate readings or complete failure. These issues may require replacement of the affected components to resolve them .
Electric Door Lock Drive Failure: Over time, the electric door lock drives in the FX35 can freeze due to mechanical wear, causing them to malfunction. Regular maintenance and replacement of worn-out components can help prevent this issue .
Rear View Camera and Music System Failure: The rearview camera and music system in the FX35 can fail due to poor contact in the wiring or heating damage from prolonged exposure to the Sun. Regular maintenance and protection from extreme temperatures can help prevent these issues .

While the Infiniti FX35 has above-average reliability scores, it is essential to be aware of these common problems and address them promptly to ensure the vehicle's longevity and safety. Proper maintenance and regular inspections can help prevent many of these issues and ensure a smooth and enjoyable driving experience.

Negative 2006 Infiniti Fx35 car reviews

Cleveland Corkery 2025-01-24

The car has some great power and features, and I particularly love the back-up camera. The controls are very easy to use, which is a plus. However, I did find that the rear seat belts are quite difficult to buckle, as they are jammed down practically into the seats. It took my 6-year-old months to be able to do it, and even I found it challenging at times. Additionally, I noticed that the A/C has a moldy smell, which is a bit disappointing given that the car only has 8K miles on it. The headlights don't shine out far enough, despite adjusting them, which is a bit of a letdown. The gas mileage is not great either. Lastly, the window squeaks when rolling down, and although I have complained twice already, it still squeaks. Overall, it's a good car, but I'm not sure if I would buy it again.
Fredrick Oberbrunner 2025-01-13

I wrote a review 2 years ago when I leased the car, but now after 2 years 30k miles later I've changed my opinion. The FX is purely eye candy and has no uses as an SUV. It lacks in space (trunk area is half of any other SUV & passenger leg room is minimal) and my family of 4 barely fits in the car (can't even take road trips because it's so small). The snow feature sounds like a tonka truck falling down stairs when it activates. Services cost more than my BMW M3 and parts are very expensive. If the weather gets below 32 degrees the car's performance and driver-feel becomes sub-par. After I hit 20k miles the car started to feel like it had 80k miles. I would not purchase this car again!
Jovanny Kihn 2024-03-12

Hi there! I hope you're doing well. I wanted to share that I recently purchased a car about a month ago. Unfortunately, after just two weeks, the engine light came on. I took it to the dealership, but they couldn't find the problem causing the light to stay on. As a result, I've been driving around in a loaner car for the past two weeks.
Selmer Hansen 2024-02-01

I love the exterior design, and the engine performance is very sporty. The ride can be a bit rough, but overall it's a great car!

I rarely write reviews, but I just had to share my thoughts on this amazing car. I had the pleasure of leasing a 06 Black Obsidian on Wheat FX35 AWD w/ Sport/Tech Packages and it was an absolute joy to drive. The handling, seating position, height, exhaust note, Bose system, and Navigation were all perfect. The seats were incredibly comfortable and I always looked forward to getting behind the wheel. Even after all these years, I'm still on the lookout for a 06-08 FX35 because it was truly the perfect car for me. The car held its resale value well and I was impressed with the buy price they offered me after my lease was up. I've owned and driven many cars, including a 745i and a Z4 3.0si, but nothing compares to the happiness I felt driving my 06 FX35. I recently test drove a 2016 QX70, which was nice, but it just wasn't the same. While I would love to look into the FX50S, for now, I'm more than happy with my 06-08 FX35. I highly recommend this car to anyone looking for a great driving experience.
Avery Yundt 2025-01-14

I've owned my FX for two months now and I'm still having a difficult time getting used to the ride. The ride is very rigid and the steering wheel vibrates when hitting a bump. However, if you're looking for a sporty ride, this car might be perfect for you. If you're looking for a more comfortable ride, you might want to consider another vehicle.
Ari Block 2025-01-14

I'm so glad to hear that you're enjoying your 2006 FX! The growl of the exhaust and the acceleration sound amazing, and the exterior styling is unbeatable. It's great to hear that the FX35 has exceeded your expectations and that it was the perfect choice for you. You did a great job researching other SUVs, and it's clear that the FX had the best balance of performance, price, and design. I'm thrilled to hear that you're extremely pleased with your purchase and have no regrets!
Jaren Erdman 2025-01-04

I turned in my G35 sport coupe (shed a tear) and got my FX35 because I needed more space. However, I didn't want to give up the feel that Infiniti builds into its vehicles. The FX has all the power and feel of a sports car packed into the shell of a crossover SUV. Driving the FX does not feel like you're driving a truck, unlike when I test drove the Pilot, Rav4, and Forrester. The FX is in a whole different class, but I love the solid feel of this vehicle. I got the space I needed, and the unique styling, performance, and reliability that I felt only Infiniti knew how to combine.
