2021 Infiniti QX80

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 QX80.

Transmission Automatic (S7)

The 2021 Infiniti QX80 is a full‑size SUV equipped with a 7‑speed automatic transmission and requiring 6.8 quarts of 0W‑20 engine oil, achieving EPA ratings of 14 city, 20 highway, and 16 combined mpg. In terms of reliability, the model year recorded 7 total owner complaints—the most common concerning the fuel/propulsion system—and was subject to 2 recalls. Within the model’s complaint history spanning 2014 through 2026, the 2021 QX80 sits between the highest‑complaint year (2014, with 20) and the lowest (2022, with 1), indicating a moderate reliability position that improved markedly from the early years but still fell short of the near‑flawless record that followed.

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; spark plugs at 105,000 mi; coolant at 105,000 mi. The big-interval services (at 105,000 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 2021 Infiniti QX80 falls within a generation-long downward trajectory in technical service bulletins, which declined from a high of 167 in 2015 to 98 in 2021 while continuing to fall in subsequent years, even as owner complaints moderated to 7 versus the 14-20 reported annually from 2014 through 2017. Against its immediate neighbors, 2021 registered one more recall than 2020 and two more than 2022, marking a localized high point in recall activity amid otherwise low complaint volumes. Federal records show the leading complaint areas as Fuel/Propulsion System (2), "Vehicle Speed Control,Engine" (1), "Power Train,Vehicle Speed Control,Engine" (1), and Visibility (1), with zero crash-related and zero fire-related complaints on file. Because the data does not specify the root cause of the recalls or the exact nature of the reported drivetrain and fuel-system concerns, the 2021 model must be evaluated on its numeric profile alone. With historically low owner complaints, no reported crash or fire incidents, and moderate recall exposure, the 2021 QX80 represents a comparatively solid used purchase, contingent on confirming that all three recalls have been completed.
