Built from official NHTSA complaint and recall data · data through 07/14/2026
Source: U.S. NHTSA complaint & recall data. Complaints are unverified reports from vehicle owners — a complaint is not a confirmed defect.
The most-reported problem — Engine (15.9% of complaints) — has no NHTSA recall or open investigation on file.
Engine complaints here are 2.5× the median for that category across the 2583 model-years tracked on this site.
None of the 6 most-reported categories on this page have a recall or open investigation on file — they rest on unverified owner reports alone.

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 258 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.
