Additional Notes

  • The Hyundai KONA OS (USA) transfer case fluid specifications cover two distinct engine configurations in AWD form: the 1.6 T-GDI and the 2.0 MPi. The 1.6 T-GDI transferbox holds 0.47–0.52 liters, while the 2.0 MPi transferbox holds 0.4 liters across 2018-2021 model years, rising to 0.5 liters for 2022-2023.
  • A range value such as 0.47–0.52 liters for the 1.6 T-GDI transferbox reflects a tolerance band rather than a single fixed fill point, which is common in transfer cases where fluid level is verified through a fill plug rather than measured by volume alone.
  • Both the 1.6 T-GDI and 2.0 MPi AWD configurations carry a separate coupling capacity of 0.48 liters across all listed model years. The coupling is a distinct fluid chamber from the transferbox itself, so both figures apply simultaneously to a fully serviced AWD unit.
  • For the 1.6 T-GDI AWD in 2018-2019, the normal-use transferbox service interval is a check at 48,000 km or 24 months. The 2019-2021 and 2022-2023 specifications shift to a check interval of 8,000 miles or 12 months, indicating a more frequent inspection schedule in later model year documentation.
  • Under severe use conditions, the 1.6 T-GDI AWD (2018-2019) transferbox specifies a fluid change at 72,000 miles. Severe use typically encompasses conditions such as frequent towing, off-road operation, or repeated short-trip driving, which accelerate fluid degradation relative to normal use.
  • The 2.0 MPi AWD transferbox carries a normal-use check interval of 30,000 miles or 48 months for both 2018-2019 and 2019-2021 configurations. At 48 months, the time-based trigger is notably longer than the mileage-based one, meaning low-mileage vehicles would still reach a service point on the calendar interval alone.
  • Under severe use, the 2.0 MPi AWD transferbox specifies a fluid change at 75,000 miles for both 2018-2021 model year groups. A change interval, as opposed to a check interval, means the fluid is replaced rather than simply inspected for level and condition.
  • The 2.0 MPi AWD for 2022-2023 specifies only a normal-use check interval of 8,000 miles or 12 months, with no severe-use change interval listed for that model year range, unlike the 2018-2021 entries which include both normal and severe use rows.
  • The 2022-2023 2.0 MPi AWD transferbox capacity of 0.5 liters is higher than the 0.4-liter figure specified for the same engine in 2018-2021. A capacity difference between model year groups on the same engine platform can reflect a revised transfer case unit with a larger fluid sump.
