Engineering Analysis (EA)
In-depth technical evaluation that may include testing, data collection from manufacturers, and detailed defect analysis.
Recall Query (RQ)
Evaluation of the effectiveness of a previously issued recall remedy, often triggered when complaints persist after a recall.
Investigation Outcomes
Investigations may result in a voluntary recall by the manufacturer, a mandatory recall order, or closure if no defect is found.
