In a recent reliability study conducted by Consumer Reports, a survey of over 140,000 vehicles revealed significant insights for potential used car buyers. The study ranked 26 auto brands based on the reliability of their models from 2016 to 2021, with Tesla receiving the lowest score of 31 points out of 100.
Leading the rankings, Lexus, Toyota, and Mazda achieved average reliability ratings of 77, 73, and 58, respectively. Following them were Honda and Acura, with scores of 57 and 53. This ranking is consistent with Consumer Reports' findings for new vehicles, which also highlighted the reliability of Japanese brands.
European brands generally occupied the middle of the list, with many scoring around 50, while several American manufacturers, including Jeep and Chrysler, were at the bottom, all scoring below 40. Notably, some brands like Porsche and Infiniti were not ranked due to a lack of sufficient data.
