Years go into preparing a new car for regulators and the fiercely competitive U.S. auto market. New cars must pass a series of safety, performance, and consumer sentiment tests long before they reach dealership lots. Despite all precautions, however, sometimes a model launch doesn’t go according to plan, and the new car exhibits safety flaws or reliability issues. Sometimes it’s simply a matter of the overall design not appealing to buyers.
To identify the worst cars introduced this decade, 24/7 Wall St. considered reviews and scores by product review organizations like Consumer Reports and J.D. Power for all new models for the 2010s decade. The models on this list received poor reviews in measures like reliability, owner satisfaction, and safety. We only considered models for which the first full year of sales was 2010 or later. Many of the models on this list are owned by brands with poor sales and reputations in the United States in recent years, including brands like Fiat, Cadillac, and Scion.
A number of the models made this list of the worst new cars of the decade because of their exceptionally poor reliability ratings. In tests by groups like J.D. Power and Consumer Reports these vehicles had an unusually high number of serious problems. These are the new cars that are most likely to break down.
For most of the models on this list, the consequences of the poor reviews were usually disappointing sales and either a major redesign or being discontinued altogether. These are the worst-selling cars of the decade.
Correction: A previous version of this piece incorrectly implied that the Fiat 500X and 500L were being discontinued by Fiat. Rather, the Fiat 500 will be discontinued but the 500x and 500L will remain in production.
