These problem counts come directly from verified NHTSA complaint data. They represent all reported owner experiences — from simple part failures to more complex electrical, drivetrain, or safety-related problems. Higher numbers don’t always mean unsafe; they can reflect model popularity and transparency in reporting.
A pre-purchase inspection (PPI) is a comprehensive evaluation of a vehicle’s overall condition performed by a qualified, independent mechanic before you buy. It goes beyond what you can see or feel on a test drive — inspecting the engine, transmission, suspension, brakes, electrical system, and body structure for signs of damage or poor repairs.
A good PPI can even uncover hidden issues not reported on a CarFax or vehicle history report, such as unreported accidents, flood damage, or frame repairs. By revealing problems that could cost thousands to fix later, a PPI helps you avoid costly mistakes and gives you leverage when negotiating the final price.
Problems in major systems — such as the engine and cooling system, transmission and drive system, electric motor, and EV battery — count more heavily because they are more likely to take the car out of service and are usually expensive to repair.
Less critical issues, like broken trim pieces or minor in-car electronics glitches, still count toward the score but carry a smaller weight. Any problem can be annoying, but the rating focuses most on issues that affect safety, drivability, and repair costs.
🟢 Excellent: Much fewer serious problems than similar-age vehicles.
🟢 Good: Fewer problems than average; issues are typically less severe or easier to fix.
🟡 Average: Roughly typical number and severity of owner-reported problems.
🟠 Below Average: More problems than most similar-age vehicles; pay close attention to known issues.
🔴 Poor: Significantly more serious or costly problems; consider avoiding this model year.
