Hyundai IONIQ, AE (EU)

Brake fluid capacity & service interval

Hyundai IONIQ, AE (EU) models require brake fluid with a capacity of 0,7 to 0,8 liters. Service intervals consist of checks every 15000 km or 12 months and changes every 30000 km or 24 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Hyundai IONIQ AE (EU) brake fluid capacity for the 1.6 GDI Hybrid (2016-2022), the 1.6 GDI Plug-in Hybrid (2017-2022), and the Electric 28 kWh (2016-2019) is specified as 0.7-0.8 liter, reflecting a service fill range for the hydraulic brake system rather than a single fixed volume.
  • The IONIQ Electric 38 kWh (2019-2022) does not carry a stated volume figure. Instead, the capacity specification reads "between min and max," meaning the reservoir level is verified against the markings on the reservoir itself rather than a measured fill quantity.
  • Across all four configurations, the brake fluid check interval under normal use conditions is set at 15,000 km or 12 months, whichever comes first.
  • The change interval for all four configurations under normal use conditions is 30,000 km or 24 months, placing a full fluid replacement on a two-year cycle regardless of powertrain type.
  • The check interval is exactly half the change interval in terms of both distance and time, meaning a fluid check falls at the midpoint between each scheduled change.
  • The 1.6 GDI Hybrid and the Electric 28 kWh share an identical specification set, including the 0.7-0.8 liter capacity range and the same check and change intervals, despite differing in powertrain architecture.
  • The 1.6 GDI Plug-in Hybrid carries the same 0.7-0.8 liter capacity and identical service intervals as the standard hybrid, with coverage beginning from 2017 rather than 2016.
