NHTSA lists 2 safety recalls and 54 owner complaints for the 2015 Kia K900. Most complaints involve exterior lighting (18) and air bags (14). The EPA rates it 18–21 mpg combined.
Kia America, Inc. (Kia) is recalling certain 2010-2019 Borrego, 2014-2016 Cadenza, 2010-2013 Forte, Forte Koup, Sportage, 2015-2018 K900, 2011-2015 Optima, 2011-2013 Optima Hybrid, Soul, 2012-2017 Rio, 2011-2014 Sorento, and 2010-2011 Rondo vehicles. The Hydraulic Electronic Control Unit (HECU) may experience an electrical short, which can result in an engine compartment fire while parked or driving.
Kia Motors America (Kia) is recalling certain model year 2015-2016 K900 vehicles manufactured December 18, 2013 to January 11, 2016 and equipped with LED headlights. In the affected vehicles, when using the multi-function light switch in "AUTO" mode, electrical resistance may build in the switch and result in the headlights flickering or turning off when driving.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“The contact owns a 2015 Kia K900. The contact stated that while driving at an undisclosed speed, the headlights and taillights were flickering or turning off unexpectedly. The contact associated the failure with NHTSA Campaign Number: 16V210000 (Exterior Lighting); however, the VIN was not included. The dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 73,000.”
“The dash is warping and the leather is rolling up across the passenger side airbag. The leather around the center channel speaker is rolling back as well and going to cover the daytime running lamp sensor if it shrinks much further.”
“My 2015 Kia K900 developed a no-start condition and displayed a “Check Brake Fuse” warning starting July 4th 2026. The vehicle will not start, and the cause of the failure is currently unknown. It was perfectly fine. I took the vehicle to an authorized Kia dealership for diagnosis and paid a diagnostic fee. The dealership inspected the vehicle but told me they were unable to determine what is causing the problem. The dealership advised me that all recalls on my vehicle are currently up to date. However, I am concerned because this model has previously been subject to a safety recall involving the Hydraulic Electronic Control Unit (HECU)/ABS electrical system and fuse due to the possibility of an electrical short and engine-compartment fire. At this time, I do not know whether my current failure is related to that system or recall. I am reporting the issue because the vehicle is displaying a brake-fuse warning, will not start, and an authorized Kia dealership has been unable to identify the cause. The vehicle is available for further inspection if requested. I would like NHTSA to document and evaluate this failure in case other 2015 Kia K900 vehicles are…”
