2013 Hyundai Santa FE cruise control problems

I was driving the vehicle on the left lane of the freeway and the acceleration suddenly gave out. The car began to slow even when I pushed on the gas. Heat gage was fine and no lights went on. I quickly got over 4 lanes of traffic to the next exit and was able to pull over to the side of the road. White smoke began to billow out of the hood on the offramp and all the emergency light indicators came on at once. I turned the car off and the smoke turned black.
