24: 1984 Ford Bronco II
There’s an old saying that goes you don’t fix something that isn’t broken. Yet you couldn’t tell that to Ford in the 1980s. The automaker saw fit to downsize the popular Bronco SUV to better compete with the Jeep Cherokee. The newly-revised Bronco was lacking many features that made the original such a popular model. There was no removable top and the lack of a V8 engine was disappointing to the many Bronco loyalists (via Motor Biscuit).
The Bronco II was a sales flop largely due to the drastic changes to the already established brand. Consumers also reported that the Bronco II was not as reliable as the full-size model. Head gasket failures were common for these trucks, as well as build quality issues that pertained to the interior of the truck. By the 1990s, the Ford Bronco II was on its way out and replaced by the much more popular Explorer.
