2005 Infiniti Fx45 problems
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 2005 Infiniti Fx45 problems
The Infiniti FX45, introduced in 2003, has been a popular choice among luxury SUV enthusiasts. However, like any vehicle, it has its share of common problems. This article will focus on the 2005 model year and the issues reported by its owners.
- Fuel System Issues: Some drivers have noticed that their 2005 Infiniti FX45 is consuming more fuel than usual or experiencing a rough idle. This may be due to a faulty fuel pressure regulator or other fuel system components. To address this issue, it's recommended to have your fuel system inspected and any faulty components replaced.
- Air Conditioning System Issues: Some 2005 Infiniti FX45 owners have reported that their vehicle's air conditioning system is not cooling effectively, or that there is a musty odor coming from the vents. This may be due to a faulty compressor or other air conditioning system components. To address this issue, it's recommended to have your air conditioning system inspected and any faulty components replaced.
- Exterior Lighting System Issues: Some 2005 Infiniti FX45 owners have reported issues with the exterior lighting system, such as non-functional headlights or tail lights, or a flickering or dimming lighting system. This may be due to a faulty lighting control module or other electrical issues. To address this issue, it's recommended to have your lighting system inspected and any faulty components replaced.
- Brake Discs and Radiators: The Infiniti FX, introduced in 2003, has two weak points: brake discs and radiators. These issues can be categorized as childhood diseases or senile problems. The radiator's upper plastic tank is particularly prone to failure, and regular cleaning of dirt can extend its life. However, access to the radiator is closed by the radiator of the air conditioner, making the cleaning process difficult .
- Timing Drive: The timing drive is chain-driven, which is almost eternal among engine compartment units. However, the air conditioning compressor clutch is prone to problems due to dirt and rust .
- Transmission: The model is equipped with a five-speed Hydro mechanical automatic transmission with the possibility of manual shifting. Serious damage to the boxes was not isolated in the first years of production, and the likelihood of problems with this unit increases with mileage. External causes of gearbox failures include cracked automatic transmission oil hoses that go to an oil cooler built into the main radiator of the cooling system .
In summary, the 2005 Infiniti FX45 has several common problems, including transmission issues, fuel system problems, air conditioning system problems, exterior lighting system problems, and issues with the brake discs and radiators. It's essential to address these issues promptly to ensure the safety and longevity of your vehicle. Regular maintenance and inspections can help prevent these problems from occurring or worsening.

Second car in a year, previously a G35 Coupe. This car is great! It has plenty of room, and more than enough get up and go. The rear back-up video is an excellent idea. If you're considering one, always remember that first and foremost, this is a sports car. Don't complain later about the taut suspension and gas mileage. After all, what do you expect from a 315 hp engine?
-
This is the best vehicle I have ever had!
-
The car has been in the shop for 55 days, but I am confident that the issue will be resolved soon. Despite the noise, I am still proud to own a $50,000 car.
-
That's a great looking car that drives like a dream! I've test driven the X5, M500, and XC90, but there's no comparison. The FX feels like a real sports car - and I have high standards, having a nearly 500 HP Nissan 300 ZXTT as my other car. While the build quality could be a little bit better - I have an annoying rattle in the driver's door - I can't think of any other problems. The manual shift could be more crisp and responsive, but overall it's a fantastic car!

I love cars! Being constantly on the go, my relationship with any automobile is one of both necessity and passion. I have owned or driven many top-end makes and models, but seldom have I been so blown away as by my FX45! I have owned this car for about 6 months, and each time I turn the ignition, I still get goosebumps. Working in Europe has given me the opportunity to drive the autobahns and unleash the full potential of the 300+ horsepower, which is an absolute blast! Not to mention the looks that I get from Cayenne and Touareg owners (should have bought my V8). From bumper to bumper, this car has given me exactly what I need and expect from a true (sport) utility vehicle!
