Understanding NHTSA Investigations

Preliminary Evaluation (PE)

Initial assessment of a potential safety defect, typically opened after receiving multiple consumer complaints about similar issues.

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.
