I recall some 35 years or so ago there was an outcry because some then current models of trucks and cars sometimes caught fire after a rear end collision. As I recall, the cause was a design problem, the tank got ruptured by other parts of the vehicle during the collision. My recollection is a bit vague on all this, but it was a compact car and a pick up truck that were most often named? Neither were GM products. Does that ring a bell with anyone else?
