The contact owns a 2018 Kia Sorento. The contact stated that while driving at 55 MPH, the vehicle lost all power while depressing the accelerator pedal without warning. The contact also stated that white smoke began to emit from underneath the hood of the vehicle. Upon inspection of the vehicle, the contact saw flames coming from underneath the vehicle as oil began to leak from the vehicle. The flames eventually dissipated and authorities were not called to the scene. Due to the failure, the vehicle was towed initially to the contact's home and later to the dealer. Once in the dealer's possession, the contact was informed that there was a hole in the engine block which had led to engine failure. The manufacturer was notified of the failure but had yet to offer any assistance. The vehicle remained in the possession of the dealer and had yet to be repaired. …

The vehicle's ignition system began malfunctioning immediately after a recall-related service (Campaign CS2312 - ignition cylinder protector installation) performed on January 9, 2026. Prior to this service, the vehicle had no ignition or electrical issues. After the repair, the ignition key became difficult to turn, and the vehicle intermittently failed to start. Additionally, multiple electrical components began to fail intermittently, including the infotainment screen shutting off, the air conditioning system stopping, and windshield wipers not operating at times. These failures create a safety concern, as they may affect visibility, driver awareness, and vehicle operability while driving. The issue was reported to the dealership, and their own inspection confirmed that the ignition key cylinder is sticking. The vehicle remains available for inspection, and the condition persists.
Having intermittent issues with the headlights turning of while driving at night. The headlights were set on "Auto". I have had this happen multiple times! Went to local dealer to report the problem & was told that they would have to drive it at night to replicate the issue. I asked if I would be charged for this & was told that if the technician could find anything that I would be charged for the technician's time. I found online that Kia had this same issue with 2015-2015 K900 vehicles & issued a recall to replace the multi-functional light switch. Losing headlight rumination can reduce visibility and increase the risk of a crash. Kia dealerships should replace this multi-function switch free of charge to the owners of Kia vehicles. There should be a recall issued for this issue because it is a huge safety issue.
