During the incident in question, the vehicle’s lane‑assist system malfunctioned in a manner I have never previously experienced. As I approached an area with multiple lane markings, the system appeared to become confused—possibly due to low‑light conditions—and abruptly pulled the steering wheel with significant force. This deviation was severe enough that I temporarily lost control, causing the vehicle to drift toward the left-side ditch. When the steering suddenly released and became limp, I attempted to correct the trajectory, but the response window was too narrow to avoid impact. The vehicle struck a wooden signpost, resulting in damage to the right headlight assembly and the complete detachment of the right fog light. No lane‑departure warnings were issued at any point. Under normal circumstances, the vehicle provides audible alerts regardless of whether lane assist is active, and I am familiar with the areas where such alerts typically occur. Additionally, the forward‑collision warning system failed to activate, despite its usual tendency to trigger even in non‑hazard situations. This inconsistency has been present since I acquired the vehicle. Prior to this event, I had also been experiencing intermittent electrical issues. I attempted to seek service at the nearest Kia dealership; however, reaching it requires traveling through a national forest during winter conditions, which is unsafe unless absolutely necessary. I attempted to file an incident report with local law enforcement, but was informed that a report could only be taken if another motor vehicle was involved. I then attempted to file a report with the DMV, but the online system requires an Oregon‑issued driver’s license. I currently hold a valid Oklahoma license and have been unable to update it due to financial constraints and an anticipated move later this year. I have experienced neck pain between my shoulders since the incident.
