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
