When it breaks
19% of reported failures happened before 30,000 miles (median 62,000 miles, from 424 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
1 investigation covering this model year, 1 of which list a recall campaign. Owners had filed 46 complaints about this component over roughly 14 months before an investigation opened.

What owners and forums say
Not built yet. This panel is meant to carry community sentiment beside the filed-complaint data, so the two can be compared. Showing something weaker here would defeat its purpose.
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.
