2021 Hyundai Accent

On August 8, 2022, the Office of Defects Investigation (ODI) opened this Recall Query (RQ) based on 3 incidents alleging front seat belt pretensioners that may rupture during deployment, on model year (MY) 2020-2022 of various Hyundai and Kia Models, resulting in 3 injuries (note: one incident occurred outside the U.S. and its territories).Between October 2021 and March 2023, Hyundai and Kia have filed the following 11 safety recalls for pretensioner rupture: NHTSA Recall No. 21V-796, 22V-069, 22V-123, 22V-127, 22V-218, 22V-354, 22V-447, 22V-458, 22V-816, 23V-094, and 23V-210.Hyundai/Kia have stated that the abnormal deployment of the pretensioners is due to over-pressurization of the pretensioner pipe that can cause metal fragments to enter the vehicle occupant compartment, which can result in injury to vehicle occupants.The various makes/models covered by the above recalls include approximately 405,900 certain 2020-2022 Hyundai Accent, 2021-2022 Hyundai Elantra and Elantra HEV, 2021-2022 Hyundai Santa Fe HEV, 2022-2023 Hyundai Santa Fe PHEV, 2020-2022 Hyundai Venue, 2021-2023 Genesis G80, 2023 Genesis G80 EV, 2023 Genesis G90, 2023 Genesis GV60 EV, 2022-2023 Genesis GV70, 2021-2023 Genesis GV80, 2021-2022 Kia Sorento HEV, and 2022 Kia Sorento PHEV.In response to ODI's investigation, in December 2022, Hyundai notified ODI that they would be conducting testing to validate subject vehicle seat belt pretensioners. This evaluation included sled testing and software testing which was performed by Hyundai and its suppliers. The tests were intended to evaluate pretensioner deployment characteristics based on the unique deployment signature of the subject and peer vehicles. ODI met with representatives from Hyundai on several occasions during the investigation to discuss testing progress and data. As a result of the testing, Hyundai was able to simulate the pretensioner failures. It was determined by Hyundai during testing, the front driver-side and/or passenger-side seat belt pretensioners may explode upon deployment in the event of a crash which can cause metal fragments to enter the vehicle occupant compartment.Hyundai thus notified ODI of their decision to proceed with a safety recall, to expand the scope of the previous safety actions.In view of the recall actions taken by Hyundai and Kia, ODI concerns have been addressed. The agency reserves the right to take additional action if warranted by future circumstances.

During a tire swap, another lug nut broke off while trying to remove it. This issue has occurred before, and it seems that the faulty lug nut problem is still present. The car has only been serviced at Hyundai dealerships, and the tires were last rotated during a service at an authorized Hyundai dealership before this incident. The affected lug nut this time was on the front passenger side.

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.

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.

Upon customer's request ONLY, the Technical Service Bulletin (TSB) 25-01-089H provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti-theft decals on the front windows. This repair procedure is being provided in addition to the previous Anti-Theft software provided under Service Campaign 993 (TSB 24-01-009H-1).

This bulletin provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti-theft decals on the front windows.

In addition to the Anti-Theft software provided under Service Campaign 993 (TSB 24-01-009H-1), a zinc reinforced ignition cylinder protector hardware upgrade is being made available to customers upon request. This supplemental security measure is to be installed at the ignition switch location and provides additional protection against the social media theft method. Vehicles not equipped with an immobilizer during production at the factory are eligible. The repair procedure shall be performed and claimed upon customer request only. Any future repairs to these vehicles in which an installed ignition cylinder protector impacts required parts and/or labor, shall be covered by HMA. Please see TSB 25-01-089H for details.
