Gas Recirculation Valve (egr Valve) problems of the 2018 Honda Odyssey

We came home from the movie theater (which was only 5 miles away) and parked our car in the our driveway. When my husband turned off the car, we immediately smelled something burning. We see smoke coming up from the hood of the car. My husband, kids and I immediately got out of the car and see wafts of smoke rising from the hood. We see fire at the under bed of the car. Within 3 minutes fire was coming up through the hood of the car. The entire hood of my car was up in flames (4-5ft tall) within 5 minutes from smoke to full fire. Firefighters thankfully put out the fire within 8 minutes from when it started. The hood had disintegrated and the entire engine and all the parts in the hood were burnt and melted. My windshield shattered from the heat. This car was less than 2 years old, 37,000 miles on it. It was bought and service los regularly at the dealership. There is no reason why the car would just combust out of the blue. Called Honda of America with no avail. And refusal of any investigation. The entire incident was captured on our security camera.
