2004 Infiniti QX56

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 QX56.

The 2004 Infiniti QX56, as presented in this overview, features an engine oil capacity of 6.6 qt and calls for a 5W‑30 API SL viscosity. During the 2004‑2013 model span it recorded the highest number of owner complaints—106 total, with service brakes the leading concern—and was subject to two recalls. This peak places the 2004 model year at the low end of the QX56’s reliability history, in stark contrast to the markedly lower complaint count of just seven seen in 2009.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 27F · 710 CCA battery, OE oil filter 152089E01A. Note the factory battery is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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 30,000 mi. The big-interval services (every 30,000 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 2004 Infiniti QX56 generated 106 federal complaints, two recalls and 104 technical service bulletins, a complaint volume that exceeds the 80 complaints recorded in 2005 and the 79 complaints recorded in 2006, while its recall count aligns with the four‑recall pattern seen in those years. In contrast, the following year 2007 saw a sharp drop to 21 complaints and two recalls, and the low complaint levels persisted through 2009 before rising again, positioning 2004 at the height of an early‑generation complaint peak. The primary complaint categories — Service Brakes (28) and Service Brakes, Hydraulic (25) — account for the majority of the 106 complaints, though the data does not specify a root cause. The model also recorded five crash‑related complaints and one fire complaint, but these represent a small fraction of the overall record. Given the elevated complaint volume and the lack of a clear safety‑related recall pattern, the 2004 QX56 is not the optimal choice for a used‑vehicle purchase compared with later model years.
