Additional Notes

  • The Hyundai Tucson NX4 (USA) automatic transaxle fluid capacity varies by powertrain, with the 1.6 T-GDI Hybrid and 1.6 T-GDI Plug-in Hybrid AWD variants both holding 6 liters, while the 2.5 GDI and 2.5 GDI AWD variants hold 6.5 liters.
  • The 0.5-liter difference between the hybrid and non-hybrid transaxle capacities reflects the distinct transmission hardware each powertrain uses, as hybrid transaxles typically integrate additional electromechanical components that alter internal fluid volume requirements.
  • The 1.6 T-GDI Hybrid AWD and 1.6 T-GDI Plug-in Hybrid AWD share an identical 6-liter capacity and a 60,000-mile change interval under normal use conditions, indicating the two hybrid variants use the same transaxle specification.
  • The 2.5 GDI and 2.5 GDI AWD are both rated at a 6.5-liter capacity with a 60,000-mile change interval, and both carry a severe use condition designation rather than a normal one.
  • A severe use condition tied to a 60,000-mile interval, as seen on the 2.5 GDI variants, means the interval is already calibrated for more demanding operating circumstances such as frequent towing, stop-and-go driving, or extreme temperatures, rather than representing a shortened interval from a longer normal-use baseline.
  • All four configurations share the same 60,000-mile fluid change interval, regardless of whether the use condition is normal or severe, making the interval consistent across the entire Tucson NX4 USA automatic transaxle lineup from 2021.
