Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 3,750 mi; spark plugs at 105,000 mi; coolant every 3,750 mi. The big-interval services (every 3,750 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2005 Infiniti FX35/45 sits at a transition point in the first-generation federal record. Complaints declined from 141 in 2004 to 105 in 2005, then fell sharply to 44 in 2006, suggesting the 2005 model was part of a broader reliability-improvement arc. However, 2005 carried the highest recall count in this window at 9, versus 7 in 2004 and 7 in 2006, even though complaints were already decreasing. The leading 2005 complaint categories were Air Bags (22), Unknown or Other (12), Latches/Locks/Linkages (10), and Structure (9), with 5 crash-related and 0 fire-related complaints, though the data does not specify root causes. Given the elevated recall activity relative to surrounding years and still-moderate complaint volume, 2005 is not the cleanest year of this generation, but it is a notable improvement over 2004. A prospective buyer should verify all recalls are completed and focus on air-bag and latch/lock function during inspection.
