Service bulletins for the 2011 Kia Sorento

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

DC_201808282018-10-09. Service bulletin. ELECTRICAL SYSTEM; ENGINE; EQUIPMENT. DEALER COMMUNICATION - RECENT KIA MEDIA REPORTS - Dear Kia Retailer, You and your customers may have seen recent media reports regarding thermal incidents in Kia vehicles or NHTSA?s announcement of the opening of a Defect Petition for fire cases involving the 2011-14 Sorentos and Optimas, and I want to update you on KMA?s response to this issue. All automobiles contain combustible materials and a vehicle fire may be a result of any number of complex factors which must be carefully evaluated by trained technicians to, if possible, determine its cause and, ultimately, determine if a defect trend exists. At Kia, customer safety is paramount and although both KMA and NHTSA have independently concluded that no defect trends exist, KMA has significantly increased its committed resources to ensure that all thermal incidents are fully evaluated.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
