Lose Power Steering problems of the 2016 Honda Accord

Last night my dashboard lost electricity for about 2 seconds and my engine stalled. I also lost power steering control. After 2 seconds, electrical components of the dashboard returned to normal, as did the power steering and engine, and everything was fine. This morning, I drove on a street & smoke entered the cabin area of the car & I pulled over immediately to a nearby gas station. I opened the hood and the battery (positive terminal) was fully engulfed in flames. A gentleman put out the fire with water from the gas station. My battery is 1/4 melted, due to the fire. Other plastic parts of the engine are also slightly melted. I called gardena Honda (in los angeles CA) and they told me my 2016 Honda Accord was not part of the battery sensor recall but the service person told me that she had seen my email and forwarded it to her supervisor, and that she would speak to him to see what they could do (given the car is apparently not part of the recall). She called me back and told me that her supervisor said to immediately bring it into the gardena, CA Honda dealership, which I did. Upon arrival (with a CO-worker who took time to help me drop off the car) the service people told me they would definitely be charging me at least $160 for a diagnosis. I then explained to them that I was misled, as when I initially called I was told that she would check to see what they could do and that she would call me back. At no time did she say I would be charged for anything. Instead, she mislead me by saying she had spoken to her supervisor and that he said to bring it in immediately. They mislead me, wasted my time, and are putting people's lives in danger as although my vehicle (2016 Honda Accord with VIN is apparently not part of the recall, my car's battery caught fire and I am sure other people's car's will also catch fire. The recall should be expanded beyond the current list.

I was driving going 45mph when the steering light came on and I lost power steering. . I pull over and restarted the car and it went away and power steering work again. . I took my car to Honda for repair . . They can't find anything wrong with it. . Got the car back after two days . . Drove it and the same issue happened . . Now I'm afraid to drive my car because if it happen on highway I'll be in big trouble. . .
