Additional Notes

  • The INFINITI QX50 J55 2.0 AWD transfer case holds 0.31 liter of fluid, a notably small capacity consistent with the compact transfer box design used in crossover-based AWD systems.
  • A check interval of 7,500 miles or 12 months applies to the 2018-2022 configuration under normal use conditions, meaning the fluid level and condition are inspected on an annual basis before a full change is due.
  • The change interval for the 2018-2022 configuration is set at 20,000 miles or 24 months under normal use, placing a full fluid replacement on a two-year cycle.
  • The 2022- configuration carries identical specifications to the 2018-2022 entry, with the same 0.31-liter capacity, 7,500-mile or 12-month check interval, and 20,000-mile or 24-month change interval under normal use.
  • Both configurations are designated for normal use conditions, meaning the stated check and change intervals are not adjusted for severe driving cycles such as frequent towing or off-road operation.
