How we score this: The score starts at 100 and subtracts points for the number of NHTSA recall campaigns and owner complaints filed for this model year, and for complaints that report crashes or fires. Newer model years get a small bonus because they have had less time to collect reports. These are raw counts and are not adjusted for how many vehicles were sold, so popular models tend to have more recalls and complaints. Complaints are unverified owner reports. This grade is not a prediction about any individual vehicle and is not an inspection: check a specific car’s VIN for open recalls and get an independent pre-purchase inspection.
Data source: All recall and complaint data is sourced directly from the National Highway Traffic Safety Administration (NHTSA) public API. Data is cached and refreshed every 7 days. Recall and complaint counts reflect data available at the time of last cache update. For the most current recall status on a specific vehicle, enter the VIN above or visit NHTSA.gov/recalls.
