What Tends to Fail First on the 2006 Infiniti FX35
The systems that tend to fail first on the 2006 Infiniti FX35, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
Severe corrosion can affect the rear subframe, lower fender wells, and rocker panels, particularly in regions exposed to road salt. This is a structural integrity concern and can lead to expensive repairs or deem the vehicle unsafe.
Common failures include power window motors/regulators, HVAC blend door actuators, dashboard display issues (fading HVAC screen), and occasional sensor faults (e.g., TPMS, ABS). These are generally nuisance failures but can be costly.
Front lower control arm bushings and rear differential bushings are prone to wear, leading to clunking noises, reduced handling precision, and accelerated tire wear. Struts can also begin to leak.

AIR BAGS:FRONTAL
Nissan North America, Inc.

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.
