Fiat is an enormous Italian conglomerate that includes all of the Chrysler brands in its portfolio. The Fiat brand was reintroduced in the U.S. in 2011 with the diminutive, retro-styled 500. Despite attractive looks and a fun driving experience, various crudities limit its appeal. The 500L proved unimpressive in our tests and is routinely among the least-reliable new cars in our reliability survey. While the 500X is stylish, it likewise had a rather mediocre performance in our testing. One bright spot is the 124 Spider, an engaging roadster that is based on the Mazda MX-5 Miata and uses a Fiat engine. Reliability and owner satisfaction are quite low for the Fiat-sourced models.
