Car Reliability Histories

How are cars holding up? The reliability history charts, included on each car model page on CR.org, give you the most comprehensive reliability information available to consumers. (To find our ratings & reliability information go to our main Cars page and select a vehicle by make and model).

The reliability data comes from our annual auto reliability survey of Consumer Reports members. In all, we received responses on over 420,000 vehicles in our latest survey, detailing 2000 to 2019, and some early introduced 2020 models.

Consumer Reports members reported on any 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. 

How to Read the Model Page Charts

To check on the reliability history of a particular year's model, start with the Overall Reliability Verdict Score. This score shows whether the model had more or fewer problems overall than the average model of that year, calculated from the total number of problems reported by members in all trouble spots. Because problems with the engine major, engine cooling, transmission major, and drive system can be serious and expensive to repair, our calculations give extra weight to problems in those areas.

More on Car Reliability

To see how the model that's currently on sale is likely to hold up, look at the New Car Predicted Reliability in the model Overview. For this rating, we averaged a model's Overall Reliability Verdict Score for the newest three years, provided the vehicle did not change significantly in that time and hasn't been redesigned for 2020. We have found that several model years' data are a better predictor than the single most recent model year. We also we include a prediction for a model that has been redesigned or is new, based on its reliability history, the manufacturer's track record, and our expert knowledge of similar models and/or one that share components.

To see a model's individual strengths and weaknesses, look at the individual scores for each of the 17 Trouble Spots. The "Average Problem Rates" chart below shows the average problem rates for models in the survey in each trouble spot by model year. Scores are based on the percentage of survey respondents who reported problems for that trouble spot, compared with the average of all vehicles for that year.

Models that score a  are not necessarily unreliable, but have a higher rate of problems than the average model. Similarly, models that score  are not necessarily problem-free, but had relatively few problems compared with other models.

Because problem rates in some trouble spots are very low, we do not assign a  or a unless the model's problem rate exceeds 3 percent. If a problem rate is below 2 or 1 percent it will be assigned a  or a  respectively. In the charts, a model year an * identifies the year of a major redesign or introduction.

Average Problem Rates

The chart below shows the average problem rates for all models in the survey in each trouble spot. For example, on average, the 2012 models have 2% problems for Engine Major, 4% for Brakes, 4% for Climate System, etc.
