Steering Column problems of the 2020 Hyundai Elantra

I started to hear a gridding noise that was progressively becoming louder when turning left or right while driving, fast or slow, highway or street, does not matter. I took the car in and the dealership had it for a week while replacing the steering assembly column (not 100% sure on exact names of parts replaced). I get the car back and the steering problems are worse. Now the steering wheel is moving around while driving. That lever that allows you to adjust the steering wheel does not work. I call Hyundai and am told they are booked and can not get my car in for almost a week. It gets to the point that driving is almost impossible so I decide to take the car in a few days early. As I'm driving on the highway going about 70mph the steering wheel drops and is flopping around and all power to the car goes off making steering even worse than what I thought was the worst it can get. Now the car is in the shop for the second time for steering problems and now an electrical problem.
