4. Chevrolet Colorado/GMC Canyon
The Colorado was the successor to the S-10 pickup truck that GM produced for decades. While the Colorado wasn’t a bad truck by any means, there were quite a few recalls that were cause for concern. First and foremost, the Colorado was part of the famous ignition switch recall in which the GM vehicles would completely shut themselves down when the vehicle is in motion. Secondly, the five-cylinder Colorado had a notable defect that had to do with the intake manifold gasket disintegrating. This defect would cause complete engine failure and loss of power.
The Colorado wasn’t a bad truck in terms of design, and it boasted a nice big cabin and plenty of seating. But the engine defects caused a safety concern that these trucks still have to this day. Models from Toyota and Nissan are far more reliable and have taken most of the market share from this generation of the Colorado. GM has since released a new version of the Colorado to make up for most of these trucks’ shortcomings. Still, if you happen to see one of these Colorado models on the used car market, it’s best left avoided.
