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.
