A design flaw in a vehicle usually isn't going to cause a car fire on its own, because there's no on/off switch for lighting a vehicle ablaze. Design flaws, however, can make conditions really ripe for a fire, and sometimes even create conditions in which an eventual fire is inevitable. Usually, the manufacturers catch on to these situations before incidents become widespread. They issue recalls to get the dangerous cars off the street and fix the problems, because no carmaker wants to be known for combusting its customers. Like all automobile fires, a design flaw is only the first step leading to a blaze. Not all design flaws result in a fire, but any number of problems can make a fire a lot more likely. Though some recent incidents will be used as specific examples on the following pages, it's worth noting that every major auto manufacturer (and plenty of the smaller ones, too) has recalled a vehicle due to a fire hazard [source: Chandler Law Group].
