Happening since 2020 random at first now permentant removal of fuse switch in order to shut off lights and the fuse switch is hot to the touch upon removal.
I've had the brakes replaced because I thought they were an issue I was having with my ABS. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.

While driving my vehicle it started producing a light smoke through defrost vent on passenger side. I stopped and opened the hood to see if something was on fire in the engine area and there was not. I got back in my vehicle and proceeded to drive it back home and within seconds I had black smoke rolling from dashboard and flames shooting from under dash on passenger side hitting passenger seat next to me I pulled over and my son and I jumped out thankfully he was in back seat and the car was engulfed in flames within seconds.
