My 2021 Elantra SEL with only 10k mi threw up those same safety alerts a couple days ago when I came back out from running an errand and started the car. Power steering was disabled as well. It was on a Sunday so couldn't call the dealership. Was able to drive home with no problems other than it steering like a truck, and planned to call the dealership yesterday morning before going to work. Started the car in the morning to check it out, and all alerts were gone, power steering was back as if nothing ever happened. Drove to work and back with no issues. Very odd. BTW, when the alerts were present on Sunday, I checked the MyHyundai app and there was a notification that something was amiss with the vehicle and gave me four different DTC codes. When I checked the app yesterday morning, the notification was gone and the car started without all the alerts, again as if nothing ever happened. My second free scheduled maintenance of the 'free three year maintenance' is due, so set up an appointment for next week, at which time I'll speak to the service manager about this strange occurrence.
