Defects Investigations

investigation iconNHTSA conducts investigations concerning the identification and correction of safety-related defects in vehicles and vehicle equipment. Information about potentially defective products can come from a variety of sources including manufacturers, consumers, law enforcement agencies, media and online sources. NHTSA looks at all available data to assess the relative frequency and potential severity of any possible safety defect using an established risk-based process. Complaint information submitted to NHTSA is continuously reviewed to identify potential safety issues that warrant follow up. NHTSA may also use resources, such as the agency’s Vehicle Research and Test Center and Special Crash Investigations, to assist with defect investigations. If NHTSA determines a safety-related defect trend exists, the agency may open an investigation to determine if the defect presents an unreasonable risk to safety that may warrant a recall by the manufacturer. 

There are several types of defect investigations that NHTSA conducts: Defect Petition, Preliminary Evaluation, Recall Query and Engineering Analysis. NHTSA works to complete a Defect Petition within four months, Preliminary Evaluation within eight months, Recall Query within eight months and Engineering Analysis within 18 months.

Compliance Investigations

check iconNHTSA tests vehicles and equipment that are available for sale to consumers to ensure that they meet Federal Motor Vehicle Safety Standards. We do this by purchasing vehicles and equipment from dealers and retailers, then testing them. If an item fails to meet federal safety standards when tested, NHTSA notifies the manufacturer. Test failures or other evidence of not meeting standards may lead to a compliance investigation.
Vehicle and equipment test results are available on our website

Vehicle Importation 

checklist iconNHTSA works with Customs and Border Protection to monitor the importation of vehicles and equipment to prevent goods not meeting U.S. standards from entering the marketplace. The agency reviews requests to allow importation of non-U.S. market vehicles under certain exceptions. Also, the agency acts to ensure that vehicles that are modified to meet U.S. standards by registered importers meet requirements and do not have safety defects.
