No evidence. This is not even abnormal. Melted aluminum components were noted in the California "Camp Fire"" https://weather.com/en-GB/international/videos/video/camp-fires-flames-so-hot-aluminum-wheels-melted-into-liquid and the Tennessee wild fires https://www.autoweek.com/news/a1858946/tennessee-forest-fires-liquefy-aluminum-rims/ The cars are sitting in a patch of scorched earth, so there was obviously a fire footprint there. Combustion of the gasoline in the cars' fuel tanks---and the rubber in the tires---were sufficient to cause flames hotter than the melting point of aluminum and glass, When it is above its melting point, aluminum is a very mobile fluid, not like sluggish syrup. As long as there is a draft of fresh air, a fire beneath an automobile would be like a fire in a stovebox, where the radiant intensity would be amplified and the flame temperature would be close to the theoretical maximum. The engine compartment would be like a chimney, with the hot gases escaping through the hood joins and the radiator. (Think about it. The same features of an engine compartment to facilitate the flow of cooling air would work in reverse to facilitate the escape of fiery air.)

You have to get over the supposition that these events in Maui are a "first." They are found at other wildfires, and we don't need to invoke DEWs to explain their occurrence, either.
