Genesis G80, RG3 (USA)

Brake fluid capacity & service interval

Genesis G80, RG3 (USA) models utilize brake fluid with a capacity range of 0,7 to 0,8 liters. Service intervals consist of 48000 miles or 48 months and 60000 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.

Additional Notes

  • The Genesis G80 3.5 T-GDI lists a brake fluid capacity of 0.7-0.8 liter for the hydraulic brake system, which represents a service fill range rather than a single fixed volume, allowing for minor variation during a fluid exchange.
  • The 0.7-0.8 liter capacity figure applies equally to both the rear-wheel-drive 3.5 T-GDI and the AWD variant, meaning the addition of all-wheel drive hardware does not alter the hydraulic brake system fluid volume in either configuration.
  • Both the 3.5 T-GDI and the 3.5 T-GDI AWD share an identical change interval of 48,000 miles or 48 months under normal use conditions, whichever comes first.
  • The G80 EV AWD, introduced from 2021, does not carry a discrete liter value for brake fluid capacity. Instead, the specification references filling between the minimum and maximum marks on the reservoir, which is a level-based fill method rather than a measured volume approach.
  • The G80 EV AWD carries a longer mileage-based change interval of 60,000 miles compared to the 48,000 miles specified for the combustion engine variants, while the time-based interval of 48 months remains the same across all three configurations.
  • All three configurations designate normal use conditions for the brake fluid change interval, meaning the stated mileage and time thresholds apply to standard driving rather than a more demanding severe-use schedule.
