Defect

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.

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.
