Stranded with My Dog: Need Repair Help

*THANK YOU GUYS SO MUCH!!!*

I had posted my situation on TikTok and was blessed to receive help. I am currently homeless and living in my car with my dog, after leaving a very toxic environment. I’ve been homeless for a little over 2 months now. I was blessed to purchase another vehicle after my last vehicle was damaged due to flooding. I assumed I was okay…that I now had reliable transportation, only to find out that the person that sold it to me wasn’t upfront about all of the issues the car has. They assured me that the car was reliable and had no mechanical issues. A day after purchasing the car from them, I noticed that the “Service Engine Soon” light is on in the dash and the car is behaving funny. I reached out to them regarding the issues and they then admitted that they were told that the car needs a new radiator. Also took the car to O’Reilly’s so they could use their code reader, and there’s apparently an issue with the spark plug and a cylinder. Car needs radiator replaced and other issues examined. I feel at a loss here. Now I am needing to put it in a shop, and also a place for me and my dog to stay until it’s out of the shop. I have funds for none of this, and feel very defeated right now. I put a majority of the funds I had raised towards this vehicle. Today the car stopped 3 times on me while I was in the middle of traffic. Blessed I was able to receive help each time to get it out of the way of traffic. Any help at all means so much to me right now. Thank you.
