Ratings Methodology

At J.D. Power, our independent and unbiased ratings, reviews and awards are based on detailed survey feedback from hundreds of thousands of verified car owners and their experiences throughout the first 3 months of car ownership through 3 years of car ownership.
Our surveys are comprised of hundreds of questions covering vehicle attributes such as quality, dependability, performance and the car owner's experiences at the car dealership.
Once the survey responses have been collected and categorized into specific price (premium vs. non-premium) and car size (compact, small, midsize and large) groups, ratings are calculated based on the range between the specific model attribute or service with the highest score in its segment and the one with the lowest score within the same segment.
From the collection, categorization and formation of ratings comes the J.D. Power 100-Point Score, Red Blade Ratings and award winners.
Our J.D. Power 100-Point Score is an overall rating given to each model per year. This score is comprised of sub categories including reliability, performance, depreciation and dealership experience with a 1-10 point scale depicted in the Red Blade Ratings. For those seeking a deeper level of detail, the Red Blade Ratings are further broken down into categories of more finite attributes defined below.
