Know if a used car is a lemon before you buy it.

Yes. Grading any car is free with no account: engine, transmission and overall grades, plus the #1 problem owners report. The premium report (from $1.99) adds every reported problem with what to check, a deal score, miles remaining and full recall data.

From complaints owners file with the National Highway Traffic Safety Administration (NHTSA), the federal agency that tracks vehicle defects and runs recalls. We've analyzed more than 800,000 of them across 121 popular models and every model year from 2000 to 2024.

Not necessarily. A grade describes how that model year did across thousands of owners. A well-maintained car from a weak year can be fine, especially if recall repairs were done. Use the grade to know what to check, and always get a pre-purchase inspection.

Yes. Rate your car with its mileage, engine and any problems you've had. We combine ratings from many owners, and once 20 owners of the same model year have rated it, their results show next to the grade. Your first car earns a free full report.

You'll get the model's overall grade across its recent years instead of a year-specific one. Brand-new model years haven't collected many complaints yet, so we label those grades as early.
