Newer model years have had less time on the road, so their counts are lower partly because owners have had fewer years to report problems.

What this data can and can't tell you

These are unverified reports that owners submitted to NHTSA, counted by model year. They are not defect findings, and they aren't adjusted for sales: a best-selling vehicle collects more complaints simply because more of them are on the road. Use the counts to compare model years of the same vehicle and to see which systems owners complain about most, not to compare how reliable two different models are. See the full methodology.
