I turned the car off, it had difficulty turning back on and the brake pedal got really hard. I had to wait about 30-45 minutes and then I was able to get the car started and brake pedal back to normal and no lights. Recently, I left the car on to run into a shop real quick and come back out. When I got back to the car, the power steering light, battery, and warning light?(amber triangle with ! In the center of it) were all on. I rev the engine and the issue went away for a quick second but then came back on. To avoid turning my car off and being stuck, I just shift to reverse and tried to leave. I’m backing out of the spot and now the backup camera is going in and out lights flashing on the dash and I’m trying to brake but the brake pedal isn’t registering and next thing you know, I’ve backed into a guard rail. On the way to drop my kids off at the babysitter, I was coming to a stop sign, and my car wouldn’t brake, i went through oncoming trafic and had to run off the road. KIA did a multi point inspection a few months apart from one another. One the car tested fine, then the second time they are saying a brake booster and no engine oil in the vehicle and that the car is basically trash. The oil light goes on and off and I can smell burning oil. I still owe 7 grand on this car and I just bought it last year and it was seamingly fine.

I drove the car to the park about 6 miles round trip with family. I came back home and started having lunch for about 25 minutes. I then attempt to start the engine to go to my appointment but then car didn't turn on. On third attempt I had a weird noise coming out of the hood and I went back inside the house to get my gloves. When i came outside of the house, the hood of the car was in flames. I called 911 to turn off the fire. The car is now at a total loss.

My vehicle is under a engine / oil consumption recall, I have contacted kia multiple time in regards to this issue as the vehicles are having engine fires due to this. I was advised by kia that my vehicle is under recall and has lifetime warranty but they will not fix or swap the motor until it goes out. This is a huge safety risk I am literally scared to drive my vehicle due to not knowing if the engine is going to go out at anytime or start on fire in the middle of the expressway.
