Lose Power Steering problems of the 2011 Hyundai Santa Fe

While driving at a rate of less than 5-10 mpg in heavy traffic on the 105 west freeway. The car suddenly lost power steering abilities and all power in the vehicle without notification lights or any other strange peculiarities. Both the check engine and oil lights went on. I managed to pull over with whatever residual power remaining as not to impede traffic but it was a terrifying struggle. The gears were also locked and unable to shift. I turned off the ignition and restarted the car. All the lights on the dashboard cleared and there are no diagnostics on the computer that reflect this problem. It is unknown what is causing the issue. Months prior (6 months) I was driving at a higher rate of speed (approx 30 mph) on the same freeway, early morning, and the same problem also happened. This could have caused me to be rear ended badly or worse.
