Recalled = an NHTSA safety recall covers this category, so a free repair exists. Under investigation = NHTSA has an open probe but no recall yet. Investigation closed = NHTSA examined it and closed the probe — this is not a defect finding; where a closed probe led to a recall we name the campaign. Not available = recall or investigation data could not be confirmed for this vehicle — it is not a “no”. Categories are matched by NHTSA's top-level component. Check your VIN at nhtsa.gov/recalls.
Percentages are the share of the 201 complaints citing each component; one complaint can cite several components. “Unspecified / other” is NHTSA’s own catch-all category — we show it rather than hide it.
