At a stop light after 10 min of normal driving on country and city roads my truck started smoking from front passenger wheel well. Smoke intensified and quickly turned black. Immediately pulled over and found flames burning through front passenger wheel liner and from around passenger side battery and intake filter. Fire was put out with fire extinguisher and engine bay sprayed down by fire truck when they arrived on scene. Fire melted through battery case leaking battery acid, parts of the intake filter housing, all surrounding electrical wiring and completely through wheel well. Was building in intensity until put out with fire extinguisher. Truck was purchased in June 2021 and had 0 active recalls. Truck was completely stock.
