2018 Kia Forte Recalls, Issues & Maintenance

The 2018 Kia Forte carries 3 open NHTSA recalls — most recently covering air bags and latch. Owners report 6 recurring issue clusters, led by “Trunk latch failure and unintended opening.” 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.

AIR BAGS

Campaign #22V031000 · Jan 25, 2022

Issue: Kia Motors America (Kia) is recalling certain 2017-2019 Sedona, Soul, Soul EV, 2017-2018 Forte, and 2017 Forte Koup vehicles. The Air Bag Control Unit (ACU) cover may contact a memory chip on the printed circuit board and damage the electrical circuit. Circuit damage may result in deactivated air bags that will not deploy in a crash.

Risk: Air bags that do not deploy as intended can increase the risk of injury in a crash.

Fix: Dealers will inspect the ACU, and either update the software or replace the unit, as necessary. Repairs will be performed free of charge. Owner notification letters were mailed March 21, 2022. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC226.

Issue: Kia Motors America (Kia) is recalling certain 2016-2018 Forte 4-door, Forte Koup 2-door, and 2018-2019 Rio 4-door vehicles.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."

Risk: A damaged engine may stall, increasing the risk of a crash.

Fix: Kia will notify owners, and dealers will replace the oil pan, free of charge. Owner letters were mailed August 16, 2021. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC210.
