2016 Kia Optima Recalls, Issues & Maintenance

The 2016 Kia Optima carries 5 open NHTSA recalls — most recently covering hoses, lines/piping, and fittings and inflator module. Owners report 7 recurring issue clusters, led by “Excessive engine 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.

Risk: If the second stage air bag does not deploy it increases the risk of injury or death.

Fix: Kia will notify owners, and dealers will replace the driver's frontal air bag module, free of charge. The recall began on May 6, 2016. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC131.
