When it breaks

Failures arrive late and spread out, which looks like wear. Service history matters more than model year here.

Limits of this figure. It counts safety complaints filed with the federal government, which is a floor on failures and not a census: problems that only cost money are under-reported. Complaint rates also reflect how likely a brand’s owners are to file, which cannot be separated from how often the car fails. Sales are calendar-year and the denominator for this nameplate is automated checks only, not verified against an external source.
