2008 Infiniti Fx35 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 Fx35 problems
The Infiniti FX35, produced between 2003 and 2008, is a popular luxury midsize SUV known for its competent engine and smooth performance. However, like any vehicle, it can develop certain problems over time. Here are some of the most common issues reported by owners:
- Timing chain problems: One of the most prevalent issues with the Infiniti FX35 is abnormal rattling or tapping noises due to timing chain problems. These noises usually occur when the vehicle reaches higher mileage, and they can be a sign of premature wear or failure of the timing chain. It is recommended to clean the throttle body every 12,000 miles without tampering with the flap to help prevent these issues.
- Wheel bearings: Prematurely worn-out wheel bearings are another common problem in the Infiniti FX35. These components may need to be replaced to resolve the issue, and it is essential to use high-quality auto parts from trusted manufacturers to ensure the best performance and longevity.
- Fuel leaks: Fuel leaks are another concern for FX35 owners. These leaks can be caused by various factors, including worn-out fuel lines, faulty fuel injectors, or damaged fuel tanks. It is crucial to address these leaks promptly to prevent potential fire hazards and ensure the vehicle's safe operation.
- Airbag defects: Defective airbags have also been reported in the Infiniti FX35. These issues can lead to malfunctions during deployment, potentially compromising the safety of the vehicle's occupants. It is essential to have any airbag-related problems addressed promptly by a qualified professional.
- Suspension issues: The rigid suspension of the Infiniti FX35 can be inexpensive to maintain, but certain components, such as struts and stabilizer bushings, may need to be replaced periodically. These parts can wear out faster on Russian cars due to the softer suspension setting, and it is crucial to monitor their condition to ensure safe and comfortable driving .
- Electrical problems: The Infiniti FX35 can suffer from various electrical issues, including malfunctioning fuel gauges, tire pressure sensors, and rearview cameras. These problems can be caused by worn-out sensors, damaged wiring, or other electrical faults. It is essential to address these issues promptly to maintain the vehicle's safety and functionality .
- Interior quality: While the Infiniti FX35 offers a luxurious interior, some owners have reported issues with the quality of the materials used. Over time, the interior may show signs of wear, including creaking seats, tapping in the steering wheel mechanism, and electrical problems with the music system .
In summary, the Infiniti FX35 is a reliable luxury midsize SUV, but like any vehicle, it can develop certain problems over time. Regular maintenance and prompt attention to any issues can help ensure the vehicle's longevity and safe operation.

Hi there! I'm so glad to hear that you're enjoying your second FX35! It sounds like you've had quite a few luxury and sports cars in the past, but the FX35 really stands out to you as the most comfortable, fun, and stylish one. As a big guy myself, I totally understand the importance of finding a car that feels comfortable and spacious. Thanks for the recommendation to check out the FX35 - I'll definitely keep it in mind!

I really liked the look of this vehicle on the road, but unfortunately my experience with it was not as positive as I had hoped. On the first day, I was disappointed to find that I could feel every bump on the road and that the steering wheel was quite tight, making it difficult to maneuver. Additionally, I had trouble finding a comfortable seating position and experienced back pain until I got used to it. It's worth noting that this car may not be the best fit for shorter individuals, so moms should be aware of that. Installing a car seat was also a bit of a challenge due to the deep metal anchors. However, I have grown accustomed to the car and now appreciate its Bluetooth, tech pack, back-up camera, and keyless entry. Although I will be looking for a different car soon, I still think this one has some great features.

One month in and I have no complaints. The car is everything it is built to be. The handling is heavy and stiff, yet nimble, and the ride is great with the spot package. It turns on a dime with a decent radius and has great 30-60 pickup. As noted, it is thirsty, but it's important to know what you're buying. This isn't a Prius. The interior is sharp and sophisticated, and it really only compares to the MDX, CX7, LR2 and Lexus RX. It stands apart from the rest and I believe it will still look great 10 years from now. This car is well ahead of its time.
Paul Halvorson 2024-08-10
Owned for 30 days. Great car! However, I must say that the front seating could use some improvement. As someone who weighs 215 pounds, I found the seating area to be too narrow to ever get comfortable. On the bright side, everything else is well thought out. The ride is quiet and the car has performed very well so far, with no trips to the dealer!
Alford Keeling 2024-08-03
The FX35 AWD is a fantastic vehicle. The sport suspension is firm, but not unbearable. The FX handles exceptionally well. The steering is precise and provides excellent feedback. I appreciate the 350Z's smaller thick leather steering wheel in the FX. The interior quality has improved drastically from the early 2003-2005 models. Plastic and leather are now much softer. I have driven the GX, RX, X5, XC90, ML, GL and Cayenne, but I believe that the FX offers the best overall value in the midsize crossover segment.
