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 2006 Infiniti FX35/45 sits at a clear inflection point in the generation’s reliability arc. Complaints plummeted from 141 in 2004 and 105 in 2005 to just 44 for the target year, and investigations dropped from three to one, signaling that many early teething issues were resolved. Recalls remained at seven, matching the 2004 level but down from a peak of nine in 2005, while technical service bulletins held relatively steady at 67. The top complaint area for 2006 is air bags with 16 reports, but the data does not specify a root cause, and the year records zero fire complaints and only two crash complaints. This sharp decline in owner-reported problems makes the 2006 model a notably better bet than the earlier years, offering a more sorted ownership experience.
