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.
