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.

In response to this trend, we engineered a software upgrade that addresses the social media theft method and made it available to owners of eligible models free of charge at authorized Hyundai dealers since early 2023. In addition to the anti-theft software, we’ve developed a new zinc-reinforced ignition cylinder protector hardware upgrade that can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because your Hyundai vehicle with the VIN listed above (“Subject Vehicle”) was not factory-equipped with an engine immobilizer and was previously eligible for the software upgrade, you are now eligible until March 31, 2027 to have the ignition cylinder protector installed — if you request it — at no cost to you through an authorized Hyundai dealership.
