Data Attribution & Reporting Methodology: Complaints are unverified voluntary submissions to the NHTSA Office of Defects Investigation (ODI). Because multiple vehicle components can be cited within a single owner complaint submission, component-level rollups may sum to more than the unique complaint count (162). Injury and fatality entries in the detailed table reflect raw values entered by reporting consumers across individual submissions; they are not deduplicated casualty statistics and may include duplicate or unverified entries. Complaint volume is not normalized for sales volume or vehicle mileage and does not represent an audited component failure rate.

Official NHTSA Defect Investigations (1)

1 CLOSED

Formal safety defect inquiries and engineering analyses opened by the NHTSA Office of Defects Investigation (ODI)

Official Federal Inquiries: NHTSA opens a defect investigation when safety screening or consumer defect trends indicate a potential unreasonable safety risk. An open investigation is a formal inquiry and does not by itself confirm a defect or result in a mandatory recall.
