Steering Failed problems of the 2004 Kia Motor Sorento

I bought my 04 Sorento from my aunt who was the only owner. It had a power steering issue at that time which took several attenpts to fix. About a month later we we visiting family and had to turn around. Upon stopping we noticed smoke from the engine compartment so I grabbed my 4 y/o daughter out of the car and by boyfriend opened the hood to find a small fire on opposite side fro where battery is. Once fire was put out we drove . 5 miles on a city rd to family. The power steering was gone at that time as well. 10/13/19 - the directional worked all day and come night time when I came out from the store and started vehicle they did not work. The next day they worked finehowever, on 10/14/19 - I started the car in am and there was a squeaky belt. I hit the gas pedal quickly and noise went away. Then while driving, the battery and brake indicator lights came on the dash and stayed on so I pulled over and shut car off. Iwas driving my daughter to the park a mile away from home when the battery and brake indicator lights came on again. I turned car off for a few minutes and when I restarted it the lights were off. I went to turn around to go home and the steering completely failed so it was extremely difficult and dangerous. I have not driven it or started it since. My mechanic camt to my home 2 days in a row and was convinced it was crankshaft bolt that snapped. He got it into his shop the following week on Friday 10/26/19 and called a short while later informing me that it was in fact the crankshaft bolt that snapped deep in the shaft and the crankshaft would need to be replaced for a cost of around $3000. I called a few other places and they said the engine would need replacing which would coat around the same. My daughter and I now have no vehicle and are walking her to school which will be difficult come winter months.
