Recall Insight
The number of affected units is not disclosed in the agency filing, which is common for drug and food recalls where lot-level tracking supersedes unit counts. Distribution scope (see Distribution below) directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory. Consumers holding this product should act on the agency's documented remedy above rather than relying on general guidance.
Within the same product category the archive holds 6 closely related recalls, 3 from NHTSA - clustering in a narrow category often points to a systemic quality-control or supplier issue rather than a one-off defect. Always verify the recall number against the official agency record before acting.
