DEALER COMMUNICATION - RECENT KIA MEDIA REPORTS, OCTOBER 26 2018 UPDATE - Dear Kia Retailer, We wrote to you in late August to provide you with an update regarding news reports regarding non-collision fires in Kia vehicles and NHTSA?s announcement of the opening of a Defect Petition for fire cases involving the 2011-14 Sorento and Optima vehicles. Since that time, we have been working cooperatively with NHTSA to analyze the safety performance of these and all Kia vehicles and added additional resources to quickly and effectively address any incidents. Recently, a non-profit consumer advocacy group called the Center for Automotive Safety (CAS) has asked for a recall of Kia vehicles for fire risk and members of the Senate Commerce Committee have asked Kia for additional information related to non-collision fires in Kia vehicles. These actions have generated additional media reports so we are providing you with additional information to assist you and your teams in addressing customer concerns.
