6. Ford Pinto
The Ford Pinto was created to be an affordable, no-frills option for American families. Its engineering reflected a relentless focus on cutting costs, resulting in a car that was honest about its basic, utilitarian mission. However, this approach backfired spectacularly when safety shortcuts—most notably, the infamous fuel tank design—led to tragic accidents and a major scandal. The Pinto’s transparency about prioritizing price above all else became a liability, severely damaging both the model’s and Ford’s reputation. History.com
