45. 1990 Ford Explorer
The Ford Explorer is one of the top selling cars in Ford’s stable, and rightfully so, the Explorer is a great vehicle. The reason the Explorer is on the list is due to the Ford/Firestone tire controversy. When first sold in 1990, Ford internal documents show the company engineers recommended changes to the vehicle after it rolled over in tests prior to production. Rather than follow through with these changes, ford lowered the recommended psi of the tires to 26. The lower pressure led to the tires getting hot, which led to tread separation, leading to the vehicle rolling over. Over 240 deaths resulted from these failure and over 3,000 estimated catastrophic injuries also resulted from the issue.
