I am reporting a severe and hazardous failure involving my 2019 Hyundai Accent. On August 8, 2025, between 9:00 p.m. and 10:00 p.m., while driving on Mopac (Loop 1), a heavily traveled highway in Austin, Texas, the vehicle abruptly experienced an overheating issue without any prior warning. The engine rapidly lost power, causing the vehicle to become unstable in traffic. I managed to maneuver the vehicle to the far-right shoulder, but when I attempted to accelerate and further distance the car from the road, the engine failed completely, emitting a severe sound resembling an explosion followed by an immediate shutdown, rendering the vehicle inoperable. This failure posed an immediate safety hazard. The vehicle was disabled in a dark and high-speed traffic environment, significantly increasing the likelihood of being struck by other vehicles. During the incident, I encountered difficulty releasing my seatbelt, briefly confining myself inside. The sudden breakdown caused me severe distress, leading to a panic and an asthma attack. Although I did not seek medical attention, the physical and emotional consequences were substantial. Since the breakdown, the vehicle has remained completely undrivable and incapable of restarting. The issue has not been replicated due to the vehicle’s inoperability. Prior to this occurrence, I had maintained regular oil changes and performed necessary maintenance, and no warning lamps, error messages, or symptoms manifested before the failure occurred. The manufacturer has been notified, and I am awaiting review by a case manager. The vehicle hasn’t been inspected by a dealership yet. Following the towing of the vehicle to my residence, a mechanic was dispatched to conduct an inspection. The mechanic indicated that the engine may require replacement. However, insurance representatives subsequently arrived and were unable to provide assistance. They asserted that the issue was of a technical and electrical nature and deemed the vehicle a tot

This car overconsumes oil rapidly. I have always taken it for oil changes when due. I put hardly any miles on my car (10k or less annually) and every time I take it for an oil change they say it is extremely low. The oil light never comes on to alert me that it is low. About a week or two ago it started making a clicking noise and it was due for an oil change so I took it for one and the technician said that this is a common issue with Hyundai cars and that there is permanent engine damage due to the overconsumption of oil. I am only halfway through paying this car off and it will cost as much as it is worth to repair it.

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.

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.

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).

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.

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