Action Status Component Subject Opened Related recall
DP22005 Closed ELECTRICAL SYSTEM:PROPULSION SYSTEM Pedestrian alert sounds
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition. 		Jan 2023

DP22003 Closed ENGINE Loss of Motive Power
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing.  There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov. 		Sep 2022

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. 		Aug 2022

(DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements.

Apr 2026 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. 11032523

Dec 2025 Other ELECTRICAL SYSTEM 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. 11026704
