Why wont my car start after decelerating while driving then turning off the car?

What is your question?

I was driving down the road in my 2012 Kia Forte and it suddenly started to make a knocking sound and stopped accelerating. I pulled to the side of the road and turned the car off. I tried to restart it but it would not turn over. It made no noise at all when I turned the key even after trying multiple times. What could be the cause of this? Please help!!!

How long has your 2012 Kia Forte had this problem?
