As auto sales hit their first slow period in years and margins are down, automakers must rely more on their reputations for quality and reliability to keep sales at current levels. According to the latest results of a highly regarded poll on auto industry customer satisfaction released Tuesday, some brands are better able to deliver a positive customer experience.

These findings come from the 2018 American Customer Satisfaction Index, which surveys car owners on their overall service and product experience with specific auto brands. Scores range from 1 to 100. According to the latest edition, the experience of owning an automobile has improved. The industry-wide score for 2018 is 82, up from 81 in 2017.

The best-rated brands this year are a make that held the spot last year and one that moved up several spots. At the other end of the list, one brand holds the unfortunate distinction of being by far the worst-rated in the ACSI. Notably, three of the five worst-ranked makes are Fiat Chrysler brands.

24/7 Wall St. reviewed the 2018 ACSI rankings to determine the best and worst car brands of 2018.
