    Air bags: air bag/restraint control module

    Kia Motors America (Kia) is recalling certain 2010-2013 Kia Forte, Forte Koup, 2011-2013 Kia Optima and 2011-2012 Kia Optima Hybrid and Sedona vehicles. In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying.

    Risk: If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.

    Remedy: Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector. For all other affected vehicles, Kia will instruct dealers to install the extension wire harness kit. The recall began September 28, 2018. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC165.
