According to Au7o's analysis of 0+ owner reports, the 2008 Infiniti FX35 has 5 documented known issues, with 1 rated critical. The most serious is Radiator Crack and Coolant / Transmission Cross-Contamination ($400-$5,500 repair). Across all issues, repair costs range from $150 to $5,500. DIY maintenance guides at au7o.io.
On the 2003-2008 Infiniti FX35, on first-generation FX35 models with the automatic transmission cooler integrated into the radiator, internal radiator failure can allow coolant and ATF to mix. Owners report radiator tank cracking or internal cooler failure, which can quickly damage the transmission if not caught early.
Diagnosis includes checking the radiator and overflow bottle for oily residue, inspecting ATF for a milky appearance, and pressure-testing the cooling system. Repair typically requires replacing the radiator and thoroughly flushing the cooling and transmission systems; if contamination was severe, transmission repair or replacement may also be needed. Costs range from about $400 for early radiator replacement to $5,000+ if the transmission has been damaged.

On the 2003-2012 Infiniti FX35, the FX35 commonly develops intermittent failures of the camshaft position sensors and sometimes the crankshaft position sensor, causing stalling, hard starts, or limp operation. Heat and age degrade the sensor electronics, and this issue is widely reported across Nissan/Infiniti VQ applications of the era.
Diagnosis is done by scanning for correlation or sensor circuit codes and monitoring live RPM/cam signals during crank and road test. Repair usually involves replacing one or both cam sensors and sometimes the crank sensor, preferably with OE-quality parts because low-cost sensors often cause repeat faults. Typical repair cost is about $150-$450 depending on how many sensors are replaced and labor rates.

On the 2003-2012 Infiniti FX35, the FX35 is well known for front-end clunks, loose steering feel, and uneven tire wear caused by worn front lower control arm bushings, compression rod bushings, and sway bar end links. The vehicle's weight and sporty suspension tuning accelerate bushing wear, especially on rough roads and higher-mileage examples.
Diagnosis involves checking for play in the lower control arms, tension/compression rods, ball joints, and sway bar links while the suspension is loaded. Repair usually means replacing the worn arm assemblies or bushings and then performing a four-wheel alignment. Typical cost is about $300-$1,000 depending on whether one side or multiple front suspension components are renewed.

On the 2003-2012 Infiniti FX35, many FX35 owners report steering wheel shake or pedal pulsation during braking, usually traced to front rotor thickness variation and heat-related brake judder. The heavy curb weight and sporty driving style of the FX35 can accelerate front rotor wear, especially with lower-quality replacement pads and rotors.
Diagnosis includes measuring rotor runout and thickness variation, checking caliper slide movement, and inspecting pad deposits. Repair generally involves replacing front rotors and pads together, cleaning and lubricating slide pins, and torquing wheels properly to prevent repeat distortion. Typical cost is about $250-$700 depending on parts quality and whether calipers or hoses also need service.

On the 2003-2012 Infiniti FX35, a common Nissan/Infiniti issue on this era of FX35 is inaccurate fuel level readings caused by wear or contamination of the fuel level sending unit inside the tank. Owners report the gauge sticking, dropping suddenly, or showing empty with fuel still in the tank, sometimes accompanied by a check engine light.
Diagnosis involves comparing scan-tool fuel level data with actual tank fill amount and checking for sender-related codes. Repair typically requires replacing the affected fuel level sender or pump module assembly through the access panel under the rear seat/cargo area, depending on configuration. Typical cost is about $300-$800 using quality parts and new tank seal hardware.

AIR BAGS:FRONTAL
Nissan North America, Inc. (INFINITI) is recalling certain 2003 INFINITI FX35, 2006-2008 FX35 and FX45 vehicles that previously received a replacement front passenger air bag assembly under recall number 20V-008. The air bag cushion was folded incorrectly, which could increase internal pressure and tear the air bag cushion during deployment.
AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE
Nissan North America, Inc. (Nissan) is recalling certain 2001-2003 Maxima, 2002-2006 Sentra, 2002-2004 Pathfinder, 2007-2011 Versa Sedan and Versa Hatchback, 2001-2004 Infiniti I30 and I35, 2002-2003 Inifiniti QX4, 2003-2008 Infiniti FX35 and FX45 and 2006-2010 M35 and M45 vehicles. The vehicles are equipped with non-desiccated, frontal passenger air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.

Nissan North America, Inc. (Nissan) is recalling certain 2012 Nissan Versa hatchbacks originally sold, or ever registered, in Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan) and the U.S. Virgin Islands, or "Zone A". Additionally, if not included in "Zone A" above, Nissan is recalling certain 2009-2010 Infiniti M35 and M45 and 2009 Nissan Versa sedans and hatchbacks originally sold, or ever registered, in Arizona, Arkansas, Delaware, the District of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia, or "Zone B". Additionally, if not included in "Zone A" or "Zone B" above, Nissan is recalling certain 2005-2008 Infiniti FX35 and FX45, 2006-2010 Infiniti M35 and M45, and 2007-2008 Nissan Versa vehicles originally sold, or ever registered, in Alaska, Colorado, Connecticut, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wisconsin, and Wyoming. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
STEERING:COLUMN
Nissan North America, Inc. (Nissan) is recalling certain model year 2008 Infiniti EX35 vehicles equipped with the power tilt/telescope option included in the premium package, manufactured June 29, 2007, to April 25, 2008, 2009 Infiniti FX35 and FX45 vehicles manufactured October 31, 2007, to April 16, 2008, and 2009 Nissan GT-R vehicles manufactured March 14, 2007, to April 25, 2008. The steering column outer tube may not be round, resulting in extra stress being applied to the upper steering bearing. This stress may cause the bearing retainer to fracture, creating extra play in the steering wheel or a possible loss of steering.
