Why Raw Complaint Counts Are Not a Score

NHTSA complaint counts are self-selected reports. They are not normalised for sales volume and they are not a reliability score. YearTell does not publish stars, “best year” lists or advice to avoid a vehicle.

A high complaint count can mean a popular vehicle, an old vehicle, a well-publicised defect, or a year that owners bother to report. It cannot, by itself, mean the year is unreliable.

YearTell does not divide by vehicles sold, because there is no public sales series that matches the NHTSA nameplate file at the same grain. Without that denominator a ranking would be a story about volume, not about risk.

That is why titles say “problems” and “complaints” and why the site will not say “years to avoid”. The useful page is the year-page with the table, the recalls and the narratives.

If two adjacent years both have enough on file, open the equal-exposure comparison. That window asks a narrower question: in the first months on the market, did one year collect more reports than the other? It still is not a reliability score.
