2008 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 2008 Infiniti Fx45 problems
The Infiniti FX45, a luxury SUV produced between 2003 and 2008, is known for several common problems reported by owners. These issues span across different model years and components, including the engine, transmission, fuel system, air conditioning, and exterior lighting system.
Engine problems are prevalent in the Infiniti FX45, with oil leaks being a common complaint. This issue may be due to worn-out valve covers or a leaking oil cooler.
Transmission issues are another area of concern for Infiniti FX45 owners. Some drivers have reported difficulty shifting gears, particularly between second and third gears, which may be due to a faulty transmission solenoid or other transmission problems.
Fuel system issues have also been reported by some 2006 Infiniti FX45 owners. These problems include increased fuel consumption and rough idle, which may be due to a faulty fuel pressure regulator or other fuel system components.
Air conditioning system problems are also common in the Infiniti FX45. Some drivers have reported that their vehicle's air conditioning system is not cooling effectively, or there is a musty odor coming from the vents. This may be due to a faulty compressor or other air conditioning system components.
Exterior lighting system issues have been reported by some owners of the 2008 Infiniti FX45. These problems include headlights or tail lights not functioning properly, or the lighting system flickering or dimming. This may be due to a faulty lighting control module or other electrical issues.
In summary, the Infiniti FX45 is known for several common problems, including engine issues, transmission problems, fuel system problems, air conditioning system problems, and exterior lighting system problems. If you own an Infiniti FX45, it is essential to be aware of these potential issues and address them promptly to prevent further damage and maintain the vehicle's performance and longevity.
What engine is in the FX45?
4.5-liter
But the FX45 comes only with Infiniti's 4.5-liter 315-horsepower V-8 (courtesy of the Infiniti Q45) and all-wheel-drive. Both vehicles are mated to a standard five-speed automatic transmission. Infiniti provided an FX45 for testing. It proved to be quite powerful.
How much HP does a 2008 Infiniti FX45 have?
320 hp
A 4.5-liter V8 making a potent 320 hp and 335 pound-feet of torque powers the Infiniti FX45. A five-speed automatic transmission with a manual-shift mode is the sole gearbox, and every FX45 channels its power through an all-wheel-drive system that features a rear bias to preserve its sporty handling capabilities.
Is Infiniti FX45 fast?
Did I mention these things had a great exhaust? The V8 was the one you wanted though. The FX45 was able to hit 60 mph in just 6.3 seconds, besting both the Mercedes-Benz ML 55 AMG and the BMW X5 4.6is; top speed was 149 mph.

I previously leased a 4.4l X5 before my Infiniti and had to get rid of it due to all of the malfunctioning electronics. However, the FX is far superior! It's faster, handles better at high speeds, and all the electronics work perfectly. Plus, it's even cheaper! :)

This vehicle is incredibly fast! The V8 engine produces great torque, and the car just shoots forward when accelerated. The AWD system keeps the power down and makes the car almost bullet-proof in the rain. The exterior looks great, and the interior is very comfortable, although not exactly well designed. I previously owned an FX35 but traded it in for the FX45 and have not regretted the decision at all. It's worth noting that this car was not made to carry a ton of stuff or more than 4 adults. However, I can still fit all my garage sale junk in the back, and my kids fit comfortably in the rear.

Hi there! I have a fun vehicle parked next to my Porsche.

The title says it all! You won't believe it, but this is the best vehicle I have ever owned. I have never had any maintenance problems and it has outstanding performance. It's so reliable and has excellent utility, while still performing like a sports car!

Hey there! I think your ride is pretty cool, but it could use a bit of work.
