“Brake fluid leaking from the master cylinder reservoir cap had been reported to enter the vehicles’ automatic braking system (ABS) wiring harness electrical connectors, causing short-circuits, melting, and fires,” the NTSB reported. By 2012, the National Highway Traffic Safety Administration knew of at least 260 vehicles that experienced a non-crash related fire.

Last i checked EVs also use brake fluid and they could end up exploding the same way. Please post a link to an ICE vehicle spontaneously combusting while off due to spontaneous combustion of the gasoline contained in its tank.
