Additional Notes

  • The Hyundai Sonata LF/LFA (EU) 1.6 T-GDI uses a semi-automatic transaxle rather than a conventional automatic, setting it apart from all other engine variants in the 2015-2019 lineup, which are paired with fully automatic transaxles.
  • The 1.6 T-GDI semi-automatic transaxle has a notably small fluid capacity of 1.9-2 liters, which reflects a service fill volume typical of a dual-clutch or similar semi-automatic unit rather than a traditional torque-converter automatic, where capacities are considerably higher.
  • Under normal use conditions, the 1.6 T-GDI semi-automatic transaxle carries a check interval of 48 months or 60,000 km with no fluid change specified, while severe use conditions add a fluid change requirement at 90,000 km alongside the same check interval.
  • The Sonata Hybrid automatic transaxle holds 6 liters of fluid, the lowest capacity among the fully automatic units in the range. Under severe use, a fluid change is specified at 90,000 km, and a check is required at 60,000 km or 48 months.
  • The 2.0 T-GDI automatic transaxle has the largest fluid capacity in the lineup at 7.8 liters. Under severe use, a fluid change is specified at 90,000 km, while normal use carries no change interval.
  • Both the 2.4 GDI (138 kW) and 2.4 MPI (126 kW) variants share an identical automatic transaxle fluid capacity of 7.1 liters across their respective normal and severe use specifications, despite differing in output and induction method.
  • The 2.0 MPI automatic transaxle has a fluid capacity of 7.3 liters and carries only a severe use specification, with a fluid change interval of 90,000 km.
  • Across the 2.0 T-GDI, 2.4 GDI, 2.4 MPI, and 2.0 MPI automatic transaxle variants, the severe use condition consistently specifies a fluid change at 90,000 km, while normal use conditions for the same variants carry no change interval in the specifications.
  • The Sonata Hybrid shares the same check interval structure as the 1.6 T-GDI semi-automatic, with a 48-month or 60,000 km check under normal use and a 60,000 km or 48-month check under severe use, making these two configurations the only ones with a defined check interval in the specifications.
