2021 Infiniti QX50 - Electric Vehicle Guide
The 2021 Infiniti QX50 belongs to a Infiniti QX50 lineup that Know Your Ride tracks across 4 model years, from 2020 to 2025. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion QX50 entirely. It is configured as front-wheel drive with an automatic (av-s8). The 2021 sits mid-run, with both earlier (2020) and later (2025) QX50 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 13 scheduled maintenance items for this vehicle, the earliest interval falling at 7,500 miles. Documented torque values include lug nut 80 ft-lb.
