About NHTSA complaints
NHTSA's Office of Defects Investigation (ODI) collects safety-related complaints from vehicle owners. A pattern of similar complaints can trigger a formal investigation and — if a defect is confirmed — a recall. Each complaint receives an ODI number you can reference at /complaints/{odi-number}.
Complaints are user-reported and unverified by NHTSA. Use them as early signal alongside recall campaigns and defect investigations, not as proof of a defect.
