Additional Notes

  • The rear differential fluid capacity across all Genesis Coupé BK configurations is 1.4 liters, a figure consistent with a service fill rather than a full overhaul, as overhaul procedures typically require additional volume to account for complete drainage of residual fluid from bearing cavities and housing passages.
  • The 2.0T from 2010-2012 carries a rear differential fluid check interval of 30,000 miles or 24 months under normal use conditions, while the 2013-2014 2.0T extends that check interval to 37,500 miles or 30 months.
  • Under severe use conditions, the 2010-2012 2.0T specifies a fluid change at 60,000 miles, whereas the 2013-2014 2.0T raises that change interval to 75,000 miles, reflecting a revision in service scheduling between those generation spans.
  • The Hyundai Genesis Coupé BK 3.8 V6 from 2010-2012 shares the same 30,000-mile or 24-month check interval as the 2.0T of the same years, with a 60,000-mile change interval under severe use.
  • Beginning with the 3.8 V6 from 2012-2015, the check interval shifts to 37,500 miles or 30 months, mirroring the same revision seen in the 2.0T's 2013-2014 update, and the severe-use change interval moves to 75,000 miles.
  • The 3.8 V6 from 2015-2016 retains the 37,500-mile or 30-month check interval and the 75,000-mile severe-use change interval, keeping the same schedule established in the 2012-2015 span.
  • Across all configurations and model years, the normal use condition carries no fluid change interval, only a check interval, meaning a fluid change is not scheduled under normal use regardless of engine variant or year.
  • The severe use condition is the only context in which a fluid change interval appears in the specifications, with the change interval set at either 60,000 miles for 2010-2012 models or 75,000 miles for later configurations.
