While driving my 2025 Honda Civic Touring, the electric steering system suddenly malfunctioned without warning. While entering/navigating a roundabout, the wheels forcibly straightened out on their own, overriding steering input and causing the vehicle to crash directly into the roundabout curb/barrier. Prior to this sudden steering lockout/binding event, there were no known performance or handling issues with the car. Following the impact, the steering remains unsafe to operate, experiencing binding, severe misalignment, and persistent inability to steer smoothly. Mechanics have replaced the passengers lower control arm, ball joint, sway bar link, the passenger side strut tower, and two front tires because of the camber caused damage to the tires, but the vehicle's camber remains out of spec and the underlying steering binding/stiffness remains unresolved. I believe an internal defect or electronic lockup in the Electric Power Steering (EPS) system caused the vehicle to lose steering control prior to the impact.
