Why do cars catch fire?

Answer 1

Cars can catch fire for all sorts of reasons. Most of the time, it is because of accidents. If a car gets hit in its gas tank or the engine has taken a severe hit, a slight spark or electrical impulse, such as when batteries get ruptured, can cause a fire. Poorly maintained cars can catch fire too. Leaking gas lines, head gaskets, cracked blocks, cracked radiators, leaking fuel lines, and the list goes on, are all potential fire hazards. This is the reason why you change your fluids, especially oil every so many thousand miles. Doing so helps keeps your car's seals intact a long time. Pretty much all of a car's fluids including the car itself are flammable. Usually heat and electrical sparks plus a leaking automotive fluid (doesn't matter which one) is all it takes for a vehicle fire to start.
