Electrical system
Around 9/25/23, KIA service technicians confirmed that my vehicle had an engine fire rendering it inoperable. The incident appears consistent with NHTSA Recall Number 23V652: several engine compartment components melted due to the fire. For approximately 16 months, I persistently sought a resolution with KIA. Despite my efforts, KIA refused any corrective action & instead presented me with a $66,749.72 invoice for a new engine. This was alarming given I had purchased the most comprehensive extended warranty when acquiring the vehicle from an authorized KIA dealer (I am the original owner). The extended warranty company denied coverage, citing a general exclusion for overheating incidents. They classified the engine fire as overheating, voiding the warranty I had purchased for added protection. …
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. …
