Additional Notes
- The Hyundai Genesis BH hydraulic brake system holds 0.7–0.8 liter of brake fluid across all listed engine configurations, a range that reflects the reservoir capacity rather than a full system flush volume.
- A capacity expressed as a range rather than a fixed figure is common with brake fluid reservoirs, as the usable volume sits between a minimum and maximum mark on the reservoir body.
- The 3.8 GDI V6 covering 2012-2014 shares the identical 0.7–0.8 liter capacity and 30,000-mile or 24-month check interval with the earlier 3.8 MPI V6 covering 2009-2012, despite the difference in fuel delivery technology between the two engines.
- Both the 4.6 MPI V8 spanning 2009-2012 and the 4.6 MPI V8 spanning 2012-2014 carry the same 0.7–0.8 liter capacity specification, indicating no reservoir design change between those production periods for that engine.
- The 5.0 GDI V8 covering 2012-2014 also falls within the 0.7–0.8 liter capacity figure, meaning the larger displacement engine does not correspond to a larger brake fluid reservoir in the specifications listed.
- The service interval across all five configurations is stated as a check at 30,000 miles or 24 months under normal use conditions, whichever comes first, with the dual-trigger format accounting for both mileage-driven and time-driven fluid degradation.
- Brake fluid absorbs moisture over time through a process called hygroscopic absorption, which lowers its boiling point and is the primary reason a time-based interval of 24 months accompanies the mileage-based threshold in the specifications.
