The Ford Explorer was a completely new project for the Ford Motor Company. Positioned to compete with the Jeep Cherokee and the Chevy S-10 Blazer, it was a four-door SUV.

The Explorer was caught in the crosshairs of controversy due to a faulty roof design. When the Firestone tires were part of a multimillion-dollar wrongful death lawsuit, the reputation of the Explorer suffered. There were more capable off-road SUVs that were more compelling than the Explorer.
