The reliability charts are based on responses on more than 640,000 vehicles from our latest Annual Auto Survey conducted by the Consumer Reports National Research Center. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below.
The scores in the charts are based on the percentage of respondents who reported problems in each of the 17 trouble spots. Because high-mileage cars tend to encounter more problems than low-mileage cars, problem rates are standardized to minimize differences due to mileage. The 2017 models were generally less than six months old at the time of the survey, with an average of about 3,000 miles.
