    AIR BAGS

    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.

    Remedy: 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.

    ELECTRICAL SYSTEM:WIRING

    Kia Motors America (Kia) is recalling certain 2015-2018 Sedona vehicles equipped with manually-adjusted front passenger seats. Over time, the Occupant Detection System (ODS) wiring harness located underneath the front passenger seat may break from the seat being occupied.

    Risk: If a child is in a child seat in the front seat, a broken ODS wiring harness will not prevent the front passenger air bag from deploying in the event of a crash, increasing the risk of injury to the child.

    Remedy: Kia will notify owners, and dealers will remove the wire harness clip to prevent the wiring harness from breaking. If the harness is found damaged, the front passenger seat cushion will be replaced. These repairs will be performed free of charge. The recall began March 19, 2019. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC175.
