Kia EV9, MV (USA / CAN)

Brake fluid capacity & service interval

Kia EV9, MV (USA / CAN) models utilize brake fluid with a capacity range defined between min and max. Service intervals include checking at 8000 miles or 12 months and changing at 48000 miles or 48 months. The data covers 3 configurations.

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

TypeSpecifications
EV9 76.1 kWh (160 kW) RWD (2023- )
  • Use: Normal
  • Between min and max.
  • Check 8000 miles/ 12 months
  • Change 48000 miles/ 48 months
EV9 99.8 kWh (150 kW) RWD (2023- )
  • Use: Normal
  • Between min and max.
  • Check 8000 miles/ 12 months
  • Change 48000 miles/ 48 months
EV9 99.8 kWh (283 kW) AWD (2023- )
  • Use: Normal
  • Between min and max.
  • Check 8000 miles/ 12 months
  • Change 48000 miles/ 48 months

Additional Notes

  • All three configurations of the Kia EV9 MV share identical brake fluid service intervals, with a check due every 8,000 miles or 12 months and a full fluid change due every 48,000 miles or 48 months under normal use conditions.
  • The 48,000-mile or 48-month change interval applies uniformly across the 76.1 kWh RWD, 99.8 kWh RWD, and 99.8 kWh AWD variants, meaning neither battery size nor drivetrain configuration alters the replacement schedule.
  • Rather than a fixed fill volume, the specification for all three configurations references a level maintained between the reservoir minimum and maximum marks, which is the standard approach for brake fluid servicing rather than a measured capacity fill.
  • The hydraulic brake system note applies to all three configurations, distinguishing the brake circuit as a conventional hydraulic setup, which is relevant on an electric vehicle where regenerative braking can reduce reliance on the hydraulic system during normal deceleration.
  • The 99.8 kWh battery is shared between two distinct powertrain configurations, one rated at 150 kW in RWD form and another at 283 kW in AWD form, yet both follow the same brake fluid check and change schedule as the smaller 76.1 kWh variant.
