No NHTSA investigation covers this model year.

That is not a clean bill of health, and not a criticism of the agency: investigations open for many reasons and complaint volume is only one of them.

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.
