Lose Power Steering problems of the 2016 Hyundai Sonata

I had a power steering fail. While driving I lost my power steering, power steering light came on, and due I was able to get my car into the emergency lane. The traction control light came power steering. .

11/4/19 I had a power steering fail. While driving I lost my power steering, power steering light came on and due to traveling in the slow lane I was able to get my car in to the emergency lane. The traction control light came on only to indicate I was hitting the emergency grooves outside the lane. I turned the car off and while in process of contacting aaa - I started the car and the power steering light was off and I was able to drive home. I took the car to tarr huyandai the next morning and there were 3 codes present. My steering angle sensor was recalibrated. My concern is what caused the fail and no one seems to have an answer. This situation created a major safety hazard had I been driving in heavy traffic and this occurred and me unable to steer the car in manual mode. I contacted huyandai and apparently this has been a problem with 2016 Sonata models but my car was mfg at a plant that wasn't on recall. So at this point - the mfg plant where my vehicle was mfg apparently has the same problem with mine being the first reported. I feel totally unsafe in this car esp traveling on interstates, night time, etc since no one can answer why my power steering quit and reset when I turned the car off. This needs to be addressed before someone is killed. I was traveling on hwy 160 in morristown TN when this occurred - I am also concerned when I told tarr the power steering failed and the traction came on when hit the off road grids they listed traction control lamp was on and did not mention the power steering. That is important to remember with this case .
