2021 Infiniti QX80 - Electric Vehicle Guide
The 2021 Infiniti QX80 belongs to a Infiniti QX80 lineup that Know Your Ride tracks across 4 model years, from 2020 to 2026. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion QX80 entirely. It is configured as rear-wheel drive with an automatic (s7). The 2021 sits mid-run, with both earlier (2020) and later (2026) QX80 model years also documented.
The high-voltage battery is covered for 8 years or 100,000 miles, separate from the bumper-to-bumper warranty. Routine upkeep centers on tire rotation, DOT 4 brake fluid, Long Life battery/cabin coolant, cabin air filters and brake service rather than engine oil. Know Your Ride lists 14 scheduled maintenance items for this vehicle, the earliest interval falling at 7,500 miles. Documented torque values include lug nut 80 ft-lb.
