Additional Notes

  • The GMC Hummer EV hydraulic brake system capacity of 1.4 liters represents the fluid volume held between the minimum and maximum marks on the reservoir, rather than a total system fill or overhaul quantity.
  • A 60-month change interval applies to the brake fluid across all three configurations covered by these specifications, meaning the fluid is serviced on a time-based schedule rather than a mileage or usage-cycle basis.
  • The 60-month interval is tied to normal use conditions, which in brake fluid servicing generally reflects standard driving without the elevated thermal or moisture-absorption demands associated with severe or track-oriented use.
  • Both the Hummer EV Pickup and the Hummer EV SUV variants share an identical brake fluid capacity of 1.4 liters, with no difference recorded between the two body styles.
  • The two Hummer EV SUV configurations, rated at 466 kW and 619 kW respectively, carry the same 1.4-liter reservoir capacity and the same 60-month change interval despite the difference in power output between the two variants.
