When it breaks

21% of reported failures happened before 30,000 miles (median 80,000 miles, from 296 complaints that recorded one).

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

What NHTSA did

3 investigations covering this model year, 1 of which list a recall campaign. Owners had filed 28 complaints about this component over roughly 69 months before an investigation opened.

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.
