| EA25005 | open | DTN Air Bag Inflator Rupture | AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE | 2025-10-21 | · | · | The Office of Defects Investigation (ODI) has become aware of eight vehicle crashes in which a rupture of a Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN) air bag inflator occurred during the deployment of the driver side air bag. All eight drivers in these crashes sustained serious or fatal injuries that appear linked to the ruptures. Six of those drivers sustained fatal injuries and two sustained severe injuries. In all eight incidents, the subject inflators had been installed as replacement equipment after the vehicle was involved in a previous crash. Information gathered during NHTSA’s initial analysis of these incidents indicates that the inflators were potentially imported illegally into the United States. In conjunction with this safety investigation, NHTSA is also working with appropriate authorities to address any illegal activities associated with the importation of these inflators. As a result of the significant safety concerns relating to these inflators, as well as extensive information already obtained by ODI relating to their field ruptures, ODI is moving directly to the Engineering Analysis (EA) stage of its investigative process rather than first opening a Preliminary Evaluation. NHTSA has taken a variety of actions to address the risks posed by the importation of substandard or counterfeit air bag components. However, until recently, these risks appeared spread across a variety of components and manufacturers. As part of ODI’s continuous monitoring of this issue, the agency has obtained information to suggest that at least eight incidents involve ruptures of inflators manufactured by DTN. In parallel with this dedicated investigation into DTN inflators, ODI will continue to monitor reports of field incidents to evaluate risks from other substandard imported air bag components. In 2012, ODI first became aware of substandard or counterfeit air bag modules sold through online marketplaces, such as auction sites. NHTSA obtained examples of these air bag modules and conducted testing. None of the inflators equipped in these modules were manufactured by DTN. This testing revealed that the inflators consistently malfunctioned during deployments, such as by failing to deploy the air bag or expelling metal shrapnel due to a rupture. This led NHTSA to release a consumer advisory in October 2012 to alert the public and repair professionals to the potential dangers of substandard or counterfeit air bag modules. ODI also worked with major vehicle manufacturers, who released advisories and notifications concerning the use of such air bag modules. Since then, NHTSA has continuously monitored for reports of malfunctioning air bags that may be associated with substandard or counterfeit components. These monitoring efforts have been supported by the increased visibility the advisories have brought to the issue, and by several standing general orders in place as part of separate investigations into Takata and ARC inflators, which require certain manufacturers to report any alleged or suspected inflator field ruptures to NHTSA. Until 2017, ODI was not aware of any field incidents involving an abnormal deployment of an imported substandard or counterfeit air bag module. In September 2017, ODI became aware of a crash involving a model year (MY) 2009 Honda Civic where the air bag ruptured during deployment, killing the driver. After inspecting the vehicle and air bag parts, ODI determined that the air bag inflator was not original equipment and that the air bag module was likely a substandard import. Insufficient information existed to determine the manufacturer of the inflator in this incident, however, it does not appear to resemble those manufactured by DTN. On June 16, 2023, ODI received a Vehicle Owner Questionnaire (VOQ #11527380) alleging that the rupture of a driver side air bag caused fatal injuries to the driver of a MY 2020 Chevrolet Malibu. ODI’s assessment of the rupture indicated that the air bag in |
