What is the RepairPal Reliability Rating?

The Reliability Rating by RepairPal is a measurement of vehicle dependability based on the cost, frequency, and severity of unscheduled repairs and maintenance. RepairPal combines an extensive proprietary database including millions of vehicle repair invoices with additional automotive statistics and predictive data science to develop the most genuine reliability metric in the industry. The Reliability Rating allows you to research dependability and ownership costs related to unscheduled repairs and maintenance in addition to comparing reliability factors against other vehicles and industry averages. Individual factors contributing to a vehicle's composite Reliability Rating include cost, frequency, and severity.

Cost

The average total annual cost for unscheduled repairs and maintenance across all model years of a vehicle. Higher average cost alone does not necessarily mean a vehicle is less reliable. For example, parts and labor for your vehicle may be expensive, especially if it is a European luxury car, but if severe issues and annual average visits to the shop are low, that's a good indicator of a reliable car.

Frequency

The average number of times the vehicle is brought into the shop for unscheduled repairs and maintenance in a single year. This metric is calculated by tracking millions of unique vehicles over multiple years to determine an average number of visits per year for each make and model. Controls were included to omit small routine visits to shops such as for oil changes.

Severity

The severity component to reliability measures the probability that a repair will be a major issue. An issue is considered severe if a repair requires immediate service, is prohibitively expensive, or presents a situation that is potentially dangerous or damaging. RepairPal combines multiple disparate data sets to identify and flag these issues and then rates the severity component for each vehicle relative to that of other models in our database.
