Available adjacent years span 626–678 reports. This year has more reports than 2020.
Before you buy
- Check open recalls using the vehicle identification number (VIN).
- Review the linked NHTSA reports for symptoms that match the vehicle you are considering.
- Ask for maintenance records and arrange an independent pre-purchase inspection.
