How Reliability is Scored
Every year, CR asks its members about problems they’ve had with their cars, minivans, SUVs, and trucks in the previous 12 months. This year we gathered data on 420,000 vehicles, spanning the 2000 to 2019 model years. Members reported on problems in any of 17 trouble areas, including engine, transmission, in-car electronics, and more. We use that data to calculate reliability ratings for every major mainstream vehicle.
The predicted reliability for the 2020 models on is based on each model’s overall reliability for the past three years. We do this for redesigned models by analyzing the brand’s reliability history, the previous generation’s reliability, and if applicable, the reliability of models the vehicle shares components with. These are our predictions, and reliability can change if the automaker resolves problems or creates new ones by freshening the model.
