Engine Stall 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.

While on a trip driving on an interstate at 72 mph, in busy traffic, with cruise control on, the engine stalled. I rolled to a stop on the shoulder, and the car didn't restart. Engine lights came on, but all electronics (radio, computer screens) were working. Honda towed (under warranty) to their nearest dealership. After checking out the car, and telling me it restarted and displayed no diagnostic codes, I was sent on my way. I was told it was safe to drive as there was no problem. Still on a trip, and about 500 miles later, I was again on the interstate passing a group of semi's on about a 5% grade, with cars in front of and behind me, when the engine stalled again. This time was much scarier as I was in the passing lane, and the right shoulder was blocked by a long string of semi's. It was dangerous trying to get to the right shoulder as there were cars in front of and behind me also. I was traveling at 78 mph with cruise control on when this happened. The car restarted this time, and with it being a weekend and the service department closed, I continued home the final 550 miles (in the right lane) without incident. This was the 3rd time the engine has stalled. The first was when I was in heavy traffic on the interstate, in stop and go traffic. The temperature was 109, and at the time (car had about 10,000 miles on it) I attributed it to the temperature even though the car didn't overheat. It restarted immediately this car is the 6 speed (manual), 6 cylinder, coupe model.
