Defect Investigations

The Center for Auto Safety is the nation’s premier independent, member driven, non-profit consumer advocacy organization dedicated to improving vehicle safety, quality, and fuel economy on behalf of all drivers, passengers, and pedestrians.

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.

These complaints reveal a frighteningly large number of vehicles manufactured at the same time catching fire. Altogether, over 2.2 million of these vehicles were manufactured during model years 2011-2014. NHTSA has granted the Center’s petition to open an investigation.

[/lgc_column] [lgc_column grid=”65″ tablet_grid=”65″ mobile_grid=”100″ last=”true”]The Center has petitioned NHTSA to investigate 2017-18 Nissan Rogues based on reports of false activation of the Automatic Emergency Braking system in these vehicles. Nissan has attempted to address this defect  by issuing a Technical Service Bulletin (TSB) to dealers, but with no guarantee that owners are notified of a safety hazard or provided an opportunity to have the condition repaired.  Moreover, the services currently being offered to Nissan owners are only covered under the warranty for a limited time, rather than the far longer protection provided by a recall. Learn more.
