- [DTN DL](/bulletins/11032523.md), 2026-05-08, Other: AIR BAGS. The National Highway Traffic Safety Administration \(NHTSA\) has identified the presence of substandard and dangerous driver’s\-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. \(DTN\). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non\-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non\-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self\-inspection by vehicle owners and recommends inspection by trained technicians.
- [DTN DCS](/bulletins/11032522.md), 2026-05-08, Other: AIR BAGS. The National Highway Traffic Safety Administration \(NHTSA\) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. \(DTN\), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.
