Warning problems of the 2017 Hyundai Sonata

I purchased a brand new Hyundai Sonata se in 2017. After 1. 5 years, I took a 3-4 hour road trip from houston to longview, TX. During that trip, my steering wheel locked and I could not turn the wheel as my traction and steering wheel light lit up on my dashboard. To remedy the problem, I had to turn the engine off and back on. There was no accident but there could have been since I was driving amongst other vehicles on the interstate. This was the first of many scary incidents with my locked steering wheel. I've reported and submitted this complaint to Hyundai but they have done nothing to remedy the problem. The Hyundai dealership explained they cannot do anything unless there diagnostic machine can detect the problem. I explained that it normally happens while I'm driving and that there are several online and youtube reviews of other 2017 Hyundai Sonata vehicle owners with the same issue. I also showed the traction and steering wheel lights that come on when the steering wheel locks. Still there was nothing they could do. The vehicle is getting increasingly worse as I now must turn it off and on three times before the steering wheel unlocks. This is a danger to myself, my children, pedestrians, and other drivers. The steering wheel locks unexpectedly and without warning. I facilitate large groups and happen to mention my issue with the 2017 Hyundai Sonata today. They were alarmed about the dangers to myself and others while driving the 2017 Hyundai Sonata se. I explained that it was previously reported to Hyundai and NHTSA but nothing was done to remedy the problem. The group encouraged me to report it again. I'm doing so with little to no confidence that mentioning it will do anything. It may take someone or people being killed or seriously hurt before anything is done. I can't afford another vehicle and need it for transportation. Otherwise I would have purchased another brand of vehicle.
