Where each agency publishes its recalls
Updated October 1, 2026. Read from National Highway Traffic Safety Administration recall data. Public domain (U.S. government work). Recalls are as the agencies published them: the CPSC, FDA (food enforcement reports) and NHTSA. A firm is one firm only when its exact name and country match; the CPSC and FDA print no firm ID. Stores are listed only when the agency's sold-at text names them, and an agency often adds that more stores sold the product.
