I suspect its even worse than that. The body of the article doesn't make any claims about a tesla catching fire. It only uses EV: "a series of electric vehicle (EV) fires tied to Hurricane Ian." So there may be 0 tesla fires.

I really feel like the article buried the lede though. I really think the bigger story is that the EV can catch fire for weeks after the water damage with (I assume) no warning/diagnostic errors.

"“Lithium-ion vehicle battery fires have been observed both rapidly igniting and igniting several weeks after battery damage occurred,” Jack Danielson, executive director at NHTSA, wrote in the letter to Patronis."
