19: Ford Firestone Debacle
There’s no denying that the Ford Explorer became a massive success. But there was also controversy that drivers dealt with in the 1990s. The rollover incidents of that decade caused many deaths related to the Explorer. Part of the trouble was with the Firestone Tires on these vehicles. The entire situation became a billion-dollar problem for Ford (via WSJ).

Not to mention the adverse publicity centered around the popular Explorer. In many ways, the brand never truly recovered from the Firestone debacle. When all was said and done, Ford spent almost a billion dollars paying out settlements to the victims. The Explorer survived into the new millennium, albeit with a now-tarnished reputation.
