Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1999 QX4.
The 1999 Infiniti QX4 is an SUV built on a platform that carries a 4‑qt oil capacity filled with 5W‑30 API‑rated lubricant and paired with a 4‑speed automatic transmission, delivering EPA‑rated fuel economy of 13/17/15 mpg. Its design emphasizes a straightforward mechanical architecture, yet the model year logged 43 owner complaints, a figure that sits closer to the lower tier of the 1997‑2006 complaint history, where the most severe year (2001) reached 75 complaints and the most reliable year (2004) recorded only one. This pattern suggests that while the 1999 iteration is generally dependable, owners should monitor suspension‑related issues, which constitute the predominant complaint area and account for the two recalls documented.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
In 1999 the Infiniti QX4 recorded 43 complaints, matching the 1998 level and falling well below the 1997 peak of 46 complaints, but still higher than the 2000 average of 31 complaints. Recalls remained steady at two for 1997‑1999, increasing to three in 2000 and peaking at six in 2002, indicating a rising trend in recall volume after the target year. Investigations stayed at one each year from 1997 through 2001, then doubled to two in 2002, suggesting a slight uptick in scrutiny. The 1999 model’s top complaint areas—six each in Suspension and Structure, and four in Steering and Fuel System—mirror the broader pattern of mechanical and structural concerns that persisted throughout the generation. Given that 1999 sits near the middle of the recall and complaint trajectory and shows no significant spike in issues, it is a reasonable year to consider, provided the vehicle has been well maintained.
