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

About 8 months to a year ago my car started losing power and started using a lot of oil without an oil leak. Now it has a loud knocking noise in the engine. I have taken it to a mechanic and they said they some vehicles have recalls.

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.

I am writing to you as the owner of a 2019 Hyundai Accent, which has recently experienced severe engine issues including low compression in three cylinders, sludge build-up, and eventual engine failure. It has come to my attention that these issues are not isolated incidents but are rather indicative of a systemic problem with Hyundai Accent models of this year. As you are undoubtedly aware, numerous reports and complaints have surfaced regarding similar engine failures and defects in the 2019 Hyundai Accent. These issues have not only caused significant inconvenience and financial burden to individual owners like myself, but they also pose serious safety concerns. Given the widespread nature of these problems, it is evident that they are not mere anomalies but rather result from inherent flaws in the design or manufacturing process of the vehicles. As such, I am firmly of the belief that these issues should be addressed as part of a Hyundai class action lawsuit.

I was driving and all of a sudden my car was shaking and I lost my traction control and I could not stop my car with brakes. I have ABS and Traction control warning lights on in my vehicle.

I am writing to bring to your attention a critical safety concern regarding the 2019 Hyundai Accent, specifically regarding the persistent issue of oil burning in the engine. This problem has affected my vehicle, as well as numerous other owners of the same model year. Despite being well within the warranty period, when I brought my 2019 Hyundai Accent with approximately 50,000 miles to the dealership for repairs due to excessive oil consumption, I was met with refusal to address the issue under warranty. Upon further inquiry, it has come to my attention that this problem is widespread among Hyundai engines, with many owners experiencing similar issues. The consequences of this oil burning problem are not only financially burdensome for owners who are forced to continuously add oil between changes, but also pose a significant safety risk. Engine failure due to oil deprivation can result in sudden loss of power, leading to potentially hazardous situations, including accidents and injury. Despite numerous complaints and reports from Hyundai Accent owners, it appears that Hyundai has failed to take appropriate action to rectify this issue and ensure the safety and reliability of their vehicles. Therefore, I urge NHTSA to investigate this matter thoroughly and take necessary actions to hold Hyundai accountable for their failure to address this widespread and potentially dangerous defect in their vehicles. Owners like myself deserve a prompt and effective resolution to this issue to ensure the safety and integrity of our vehicles. Thank you for your attention to this matter.

The engine blew with only 93,000 miles on it.

The contact owns a 2019 Hyundai Accent. The contact stated that while driving at various speeds, the oil warning light frequently blinked on the instrument panel. The contact called an independent mechanic who inspected the vehicle. The mechanic discovered that the vehicle was consuming an excessive amount of engine oil. The vehicle was taken to the local dealer where an oil consumption test was performed, and an engine cleaning was performed to correct the failure. Despite the repair, the failure persisted. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 66,000.

was driving on the highway to a friends house, while i was driving a another vehicle was telling me to pull over and that there was smoke and fire underneath the car, i pulled over and crossed the bridge where there was light, once i got across i got out of the car and saw fire coming from the hood, i tried to put it out and that didn't work, so the good Samaritan who told me to pull over told me to get my son and get in her car because there was no way to save the car. As soon as we drove away the car exploded not even two mins later. insurance has inspected and claimed it a total loss, they didn't state how the fire started besides it is a total loss, now the car is totaled, insurance is paying part of it and i am working on the gap coverage to get them all the information we need and since the loan is more than what the care is worth i have no money to finance another vehicle or able to get financing especially since interest rates are so high. I have attached some pictures, it started in the engine is what it seems, once got out of the car, looked underneath and there was something leaking underneath, lost baby stuff, carseat base, stroller, formula just got earlier in the day, diapers damaged. alot was smoke damaged that was in the trunk.

Right after an oil change the oil light came on and the engine started making noises. Took it to a mechanic and they said the car lost pressure in cylinder 3 and he had 4 other kias and Hyundais with the same exact problem in the same exact cylinder. $6000 to fix...

Airbag control module is faulty code B162000

my vehicle had a fuel injector lock open flooding the car until it damaged the O2 sensor and also contaminating the engine oil. the car went through about two and a half gallons of gas in 3 minutes. during the repair process I mentioned to the dealership that the engine oil smells like gas and was a quart and a half higher than what it was after the last oil change 5 days prior. I'm believing the Quart and a half was most certainly all gas. the dealership informed me they could not repair the oil as it was not covered under warranty. if I wanted to dispute the warranty I had to contact Hyundai customer service. That was April 25th 2023 and as of May 23rd 2023 despite repeated phone calls Hyundai customer service they have never called me back. there are 2 safety issues in regards to this 1. when the fuel injector locked open dumping two and a half gallons of gas vapor in 3 minutes could easily have led to a fire or worse. 2. refusing to replace the contaminated engine oil is a safety issue because gas in the oil will cause the engine to fail. if this happens on the interstate which I drive all the time it could lead to a catastrophic accident involving me and other cars. eventually because I didn't have the money the dealership comped the oil change (I do not have the money for the change because had I changed the oil 5 days prior to the breakdown). the dealership recognized the safety hazard from contaminate engine oil but Hyundai motor company of America refuses to even call me back and if they had it their way would I would have just had me drive in a vehicle that represented a danger. the repair invoice has the oil change listed as warranty but it was not likely to be covered by warranty as the service customer service manager informed me they're going to have to fight with Hyundai and will probably end up competent in the long run. this was after 2 weeks of fighting with Hyundai to get them to pay for it and still they have never called me back.

The 2019 Accent runs amazingly well, oil changes on point and no light have gone on since purchase date. 2 weeks ago on a thursday, it started knocking and took to have checked and was told to take to Hyundai of Inland Empire/tow it/do not drive. Mr. Bushey at Hyudai verifed I need a new motor/engine and it will cost from 6k-8k . I now have a case number and the dealer is communicating with Hyundai of America/not sure what department. The car has 84k miles and the motor should not be faulty. I have been renting a car for 2 weeks, have no vehicle as a loaner and very concerned about why this original engine would just stop? The Dealer did verify it is the motor and I am still pending feedback ***** I have provided all service records to Hyundai of Inland Empire ******

The engine has been consuming excessive amounts of oil since the vehicle was purchased used in Aug 2022. Eventually during normal highway driving the engine made a loud knock, lost all power, and all of the oil began spilling out of the engine creating a large oil slick on the highway. The sudden lose of engine power led to difficulty steering and braking to move the vehicle to the shoulder of the road.

My air bad light has been displayed for several days and won’t go away. Another friends 2017 accent is doing the same thing. I am concerned for others who own these vehicles and their safety.

My 2019 Hyundai Accent engine failed at 65,004 miles. I've taken my car to a local Hyundai dealership from December 2020 up until it failing in December 2021, I've had an appointment at least once a month for my check engine light being on. They scheduled me my first appointment December 2020 and later told me they fixed the issue only for it to come back on a couple days later. I call them again letting them know and the schedule me again, same thing happens and the light comes back on a week later. This was an ongoing issue, the dealership kept telling me they fixed it and to make sure the gas cap was tightened but they could never stop my check engine light from coming back on. They told me back in September of 2021 that I had a large evap leak. When it came to finding this leak they were never successful. Fast forward to December 2021 my car started making these weird noises and I immediately brought it up to the same local Hyundai that I've been taking it to since day one. They tell me there is nothing they can do for me since they are booked up until Feb. 2022 and so were all the other dealerships near me. I understood and left then a week or two after this my car completely stops in the middle of the expressway. I had to get my car towed to Hyundai for them to tell e my engine seized, coincidental right? After an entire year of Hyundai not being able to find the issue and fix it my engine magically seizes, a 2019 Hyundai at that meaning the car is still fairly new. The entire time I was taking it there I was under warranty up until 5,004 miles ago. The powertrain warranty for a used car ends at 60,000 miles and now Hyundai expects me to pay for something I had no fault in. I have emailed, complained and spoke to almost everyone I can about this issue. I just want justice to be rightfully served and for Hyundai to cover all expenses towards my new engine replacement.

My connecting rod blew out of my engine I have a Hyundai Accent 2019, I have 65000 miles in the vehicle and have done some research as well and have seen that Hyundai vehicles for at least almost 10 years have had similar problems with their engines at around the same mileage. Maybe it’s possible that it was the same problem with my vehicle.

PULLING TO THE LEFT, AND ON THE FREEWAY AT FREEWAY SPEEDS, I HAVE TO MAINTAIN CONSTANT PRESSURE TO KEEP THE CAR TRACKING STRAIGHT. LES SCHWAB CHECKED THE ALIGNMENT AND SAID IT WAS IN FACTORY SPECIFICATIONS. THEY SWAPPED THE RIGHT AND LEFT FRONT TIRES, AND IT STILL PULLS TO THE LEFT. THIS IS A SAFETY ISSUE. MY CAR HAS 19, 000 MILES ON IT AND IS STILL UNDER FACTORY WARRANTY. THIS IS AN ONGOING PROBLEM.

WHEN YOU MADE A CLOSED TURN TO THE RIGHT, MADE A STRONG STRIKE ON THE LEFT SIDE OF THE SUSPENSION. IT SOUNDED LIKE A LOOSE NUT IN AN ALUMINUM TRAY. ONE MONTH LATER IN MY HUSBAND DRIVING THE VEHICLE MADE THE RIGHT TURNING TO HEARD THE SOUND AND MADE THE APPOINTMENT TO DISCOVER THAT WAS THE JOINT SHAFT BOLT LOOSE.
