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.
