How to read this

Each row counts what official sources have on record for that model year: recall campaigns and owner complaints filed with NHTSA, and how many of those complaints mention a crash, a fire or an injury. We do not rate reliability. Fewer complaints can also mean fewer cars sold or a newer car, so open the year before you decide. 🇺🇸 Local data
