The 2014 Kia Optima carries 7 open NHTSA recalls — most recently covering hoses, lines/piping, and fittings. Owners report 7 recurring issue clusters, led by “Steering coupler noise and play.” 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.
