2000 Infiniti QX4

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2000 QX4.

Body SUVTransmission Automatic 4-spd

The 2000 Infiniti QX4 is a midsize SUV built on the Nissan Patrol platform, paired with a 4-speed automatic transmission and requiring 4 quarts of 5W-30 API oil for service, with EPA fuel economy ratings of 13 mpg city, 17 mpg highway, and 15 mpg combined. Among the model's production run from 1997 to 2006, the 2000 model year recorded 31 total owner complaints with suspension issues being the most frequently cited problem across three recalls, positioning it between the peak complaint year of 2001 (75 complaints) and the notably improved 2004 model (just 1 complaint). This places the 2000 QX4 in a middle tier of the model's reliability trajectory—more problem-free than its immediate successor but showing more issues than the latter model years would later demonstrate.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 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 2000 Infiniti QX4 sits in a comparatively quiet interval before federal-record activity escalates across the generation. With 31 complaints, 3 recalls, 1 investigation, and 76 TSBs, it matches the moderate early-run profile and is well below the 2001 surge of 75 complaints and the 2002 peak of six recalls and two investigations. Its leading complaint categories are Suspension (5), Electrical System (4), Structure (3), and Structure/Unknown or Other (2), though the data does not specify root causes, and the single crash and fire complaints are isolated counts that do not establish a pattern. While 2000 carries one more recall than the 19971999 model years, it avoids the 2001 complaint spike and the elevated recalls and investigations that persist through 2003. That relative stability makes a well-maintained 2000 example a favorable choice within this generation, provided the three recalls have been addressed and service records are available.
