1. Pontiac Aztek

Few vehicles have garnered as much notoriety as the Pontiac Aztek. Its polarizing design—a jumble of odd angles and clashing lines—became an instant target for critics and consumers alike.
Under the hood, the Aztek’s performance was just as uninspiring, with lackluster acceleration and handling that failed to excite.
Its reputation for mediocrity has been cemented by frequent appearances on “worst car” lists, making it a cautionary tale for automakers aiming to stand out for the right reasons.
