About Defect Investigations
The National Highway Transportation Safety Administration and its Office of Defect Investigations (ODI) are responsible for investigating potential vehicle safety defects.
The investigation process covers a variety of aspects from an initial collecting and analysis of data to an evaluation, whether a defect presents an unreasonable risk motor vehicle safety or not. This process can be divided into three main phases:
1. Preliminary Evaluation (PE) – to screen the problems quickly,
2. Engineering Analysis (EA) – to determine the character and scope of the defect,
3. Formal Investigation (Case) – the final defect determination.
During each phase, the ODI decides if it is necessary to take further action and upgrade the investigation to the next phase.
As a part of this process, most recalls are initiated voluntary by the manufacturer. In some cases, a recall will be mandated by the NHTSA or the case closed without further action.
