What is a NHTSA consumer complaint?

A consumer complaint is a free-form report filed by a vehicle owner directly to the National Highway Traffic Safety Administration (NHTSA) describing a safety concern about their vehicle. NHTSA collects these reports through its Vehicle Owner Defect Report (VOQ) system and publishes them publicly. Each complaint includes the affected component, the date and circumstances of the incident, whether the failure caused a crash or fire, and any reported injuries or deaths. The owner's full narrative description is included verbatim — NHTSA does not edit or moderate the descriptions.

The database below contains over 2,215,138 individual complaints. NHTSA's investigators monitor it for clusters of similar reports — when enough owners describe the same failure mode on the same vehicle, NHTSA may open a Preliminary Evaluation that can lead to a recall. Many of the largest recalls in U.S. history, including the Takata airbag recall and the Hyundai/Kia engine fire recalls, started as patterns visible in this complaint database years before they became formal recalls.

How to interpret what you read

A few principles for reading consumer complaints usefully:

  • One complaint is anecdote; a hundred similar complaints is data. NHTSA does not investigate the truthfulness of any individual report — that's the job of the Office of Defects Investigation, which looks at the full pattern. When evaluating a vehicle, look for whether multiple owners describe the same chain of events.
  • Crash, fire, injury, and death flags are owner-set. They are not verified by NHTSA. They are still useful as a filter, because owners who tick those boxes are typically reporting more serious incidents than those who don't.
  • Component categories are NHTSA-assigned, not owner-assigned. NHTSA standardizes the component field so that complaints can be aggregated. The owner narrative often goes into more detail than the component category captures.
  • Complaint volume scales with sales volume. A best-selling model will accumulate more raw complaints than a niche model even at the same defect rate. To compare across vehicles, look at complaints per 100,000 units sold, not raw counts.

If you've experienced a defect

File a complaint. NHTSA's investigators rely on this database to detect emerging defects, and useful complaints — specific, concrete, with dates and mileage and clear descriptions of what happened — feed directly into the agency's pattern detection. The form takes about 10 minutes and is at nhtsa.gov/recalls under "Report a Safety Problem." Your complaint becomes part of the same public record that this page is built from. Owners filing detailed VOQs are how recalls get triggered.
