2015 Kia Sorento Recalls, Issues & Maintenance

The 2015 Kia Sorento carries 3 open NHTSA recalls — most recently covering hoses, lines/piping, and fittings and control unit/module. Owners report 8 recurring issue clusters, led by “Excessive oil consumption between oil changes.” Kia uses Hyundai Motor Group's powertrains, so service intervals mirror Hyundai's. Kia Promise covers the first 3 years / 36,000 miles of complimentary maintenance. Kia owners with the Theta II 2.0L/2.4L (Optima, Sorento, Sportage 2011-2019) should adhere strictly to oil intervals due to known oil-consumption issues in Kia TSBs.
