Just as Tesla Motors provided a weak earnings forecast but better-than-expected third-quarter income, federal regulators are looking into a third electric car fire, this time near Smyrna, Tenn. Regarding an accident and subsequent fire that took place on Wednesday involving Tesla’s Model S car, the National Highway Traffic Safety Administration said in a statement that it "will contact the local authorities who are looking into the incident to determine if there are vehicle safety implications that merit agency action."
