Power Steering Light On problems of the 2012 Chrysler 300

I came to a stop at a four way intersection. I accelerated to turn at about 5mph instead of the car turning the steering locked up for about 1-2 seconds. Then drove normal until I got to my destination which was a few minutes away & turned the car off. I got off the car & went into the store. Went I finished shopping I returned to the car & tried to start it up. It would not start & steering wheel & brakes were locked. The power steering light, stability control & brake lights would blink & say service engine. About an hour into this I tried to turn the car on. It turned on but the steering wheel was barley turnable I tried to move it a few inches. For the wrecker service personal once I moved it the cars steering was back to normal & working. I plan on taking it to the Dodge dealership tomorrow morning. I just really hope this does not happen again while driving at a high speed.
