Is this problem acknowledged?
The most-reported problem — Engine (35.7% of complaints) — is covered by 1 NHTSA recall campaign.
Engine complaints here are 3.2× the median for that category across the 2583 model-years tracked on this site.
5 of the 6 most-reported categories on this page are backed by a recall or open investigation; the other 1 rests on 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 423 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.
