Whether it is a dead car battery discovered at the beginning of a commute to work or broken air conditioning in the middle of summer, unreliable vehicles can create unpleasant experiences for owners. Prospective buyers are increasingly avoiding unreliable vehicles, adding pressure to the brands that consistently underperform in dependability.

24/7 Wall St. listed the most and least dependable car brands, reviewing J.D. Power’s 2017 Vehicle Dependability Study. The study gives long-term dependability scores to 31 vehicle brands based on problems reported by the original owners of 2014 model-year vehicles. A brand’s final score is the total problems experienced per 100 vehicles in the past 12 months.

The industry averages 156 problems per 100 vehicles. Lexus and Porsche tie for the best score with only 110 problems per 100 vehicles. By contrast, Fiat owners reported 298 problems per 100 vehicles, the worst score of any measured brand. Among individual models, the Toyota Camry is the most dependable vehicle.

The top two problems reported in the study were bluetooth pairing and connectivity, as well as subpar voice recognition.
