1. Pontiac Aztek (2001-2005)
The Pontiac Aztek quickly became infamous for its polarizing aesthetics, often described by critics as one of the ugliest cars ever produced. Its unconventional design—a confusing blend of SUV, minivan, and hatchback—left consumers bewildered and frustrated. Beyond its questionable appearance, the Aztek suffered from impractical design choices, including poor rear visibility due to awkwardly angled windows and cumbersome rear hatch access. Inside, confusing controls and cheap interior materials further alienated drivers, making it difficult to appreciate even its few redeeming qualities. Ultimately, the Aztek earned a reputation as a vehicle seemingly designed with deliberate disregard for driver satisfaction.
