N/A indicates that we did not receive a large enough sample size to provide data for a specific year. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Based on this data and further analysis, we predict reliability for the latest year. Extra weight is given to the more serious areas such as major engine or transmission problems. The results are presented relative to the average model that year. 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 reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey.
