Total loss of steering control which happened suddenly without warning. Traveling at 70 MPH on US 75 20 miles south of Naples Florida. Car suddenly steered hard right. Unable to control steering. Collided with guard rail, then car turned hard left, crossed 3 lanes of interstate and came to stop in grass median. Turned off engine, turned it back on, then car was able to steer normally. It was lucky that there were no cars around me at the time. Accident happened at 12:30 PM 10/11/21. There were 2 people in car. Passenger side airbags deployed. Neck soft tissue injury to one person. Travelers insurance unable to arrange towing in timely fashion, so I pried the right rear fender away from the tire, with a Jack handle. Drove slowly to Honda in Naples, FL. They sent me to Supreme Auto Collision in Naples, where the car is located now. They have asked Honda to inspect it.
