Additional Notes

  • The rear differential capacity across all Kia Sorento MQ4 AWD configurations is specified as a range of 0.53-0.63 liter. A range rather than a fixed value reflects the typical fill-to-level method used in differentials, where fluid is added until it reaches the fill plug opening rather than measured to an exact volume.
  • The 0.53-0.63 liter capacity figure applies equally to the 1.6 T-GDI Plug-in Hybrid, the 2.5 GDI, and the 2.5 T-GDI, indicating a shared rear differential housing across all three AWD powertrain variants.
  • Under normal use conditions, none of the three configurations carry a fluid change interval for the rear differential. The specification for normal use is limited to a periodic check, with no drain-and-refill requirement listed.
  • Under severe use conditions, both the 1.6 T-GDI Plug-in Hybrid and the 2.5 T-GDI share a rear differential fluid change interval of 72,000 miles, while the 2.5 GDI specifies a longer change interval of 75,000 miles under the same conditions.
  • The check interval for the 2.5 GDI under normal use is 37,500 miles or 48 months, which is slightly longer than the 36,000-mile interval assigned to the 2.5 T-GDI under the same conditions, despite both engines sharing the same rear differential capacity.
  • The 1.6 T-GDI Plug-in Hybrid carries the longest check interval among the three configurations at 40,000 miles or 48 months, applicable under both normal and severe use conditions.
  • All three configurations apply the same 48-month time-based check threshold regardless of use condition, meaning the calendar-based limit remains constant even when the mileage trigger differs between normal and severe service.
