I am submitting this complaint regarding a suspected safety defect involving a 2025 Kia K4. On XXX, the vehicle was involved in a single-vehicle crash in the Town of [XXX]. According to the driver, the vehicle unexpectedly steered off the roadway when the Lane Keeping Assist/Lane Centering steering system appeared to intervene. The driver attempted to maintain control but was unable to keep the vehicle on the roadway. The vehicle entered a ditch and struck a utility pole, causing significant damage to the passenger side. The front and rear passenger-side airbags deployed. The front passenger window shattered, sending broken glass onto the front and rear passengers. My daughter was seated in the front passenger seat, and my [XXX] granddaughter was properly restrained in a rear child safety seat. Both sustained injuries and required medical evaluation following the crash. After the collision, I began researching similar incidents and found other owners reporting concerns involving the steering assistance and lane-keeping systems. While I cannot determine the exact cause of this crash, I believe the possibility of an unintended Lane Keeping Assist or steering system intervention should be investigated because it may present a safety risk to other motorists. I respectfully request that the National Highway Traffic Safety Administration review this incident, along with any similar complaints involving the 2025 Kia K4, to determine whether a defect exists in the vehicle's stee
