Additional Notes

  • Brake fluid level for all four Hyundai Sonata DN8 configurations is specified as "between min and max," which refers to maintaining fluid within the reservoir's marked minimum and maximum indicators rather than filling to a fixed volume.
  • The 1.6 T-GDI carries a brake fluid check interval of 12,000 miles or 24 months under normal use conditions, with no separate change interval listed in the specifications.
  • The 2.5 GDI holds the longest check interval among the four configurations at 15,000 miles or 24 months under normal use conditions, also with no separate change interval listed.
  • The 2.0 Hybrid and 2.5 T-GDI share identical service schedules, requiring a brake fluid check every 8,000 miles or 12 months and a full fluid change every 48,000 miles or 48 months under normal use conditions.
  • The 48,000-mile or 48-month change interval on the 2.0 Hybrid and 2.5 T-GDI reflects a periodic replacement requirement, meaning the fluid is drained and refilled on a fixed schedule rather than monitored by level alone.
  • The 8,000-mile or 12-month check interval on the 2.0 Hybrid and 2.5 T-GDI is notably shorter than the intervals on the 1.6 T-GDI and 2.5 GDI, indicating more frequent inspection is specified for those two powertrains.
  • The 2.5 T-GDI specifications apply from the 2020 model year onward, while the 1.6 T-GDI, 2.0 Hybrid, and 2.5 GDI specifications begin with the 2019 model year.
