Car had been burning oil very quickly. I took it for an oil change, before it was due, and they said it was very low. They changed it, and I was leaving to visit my parents in Florida the next day. I checked the oil when getting there, and it was good, and I also checked it prior to heading back home, and it was still good. I was in a really bad/unsafe area at 10pm, on my way home from visiting my parents, and my car began to stall. Engine light came on. It would stall really bad when going slow, and almost died a couple times at lights when stopped, but we made it home. We got it to a mechanic, and they stated it was the engine, and it needed to be taken to the dealership. I have read that Hyundai/Kia are notorious for engine issues. My car was towed to the dealership, and they supposedly requested to see if Hyundai would cover for a replacement engine. My car is unfortunately 10,000 over the warranty mileage (100,000), but 110,000 is still not enough to be already having engine problems. Supposedly, according to the dealership, Hyundai declined, and the quote for a new engine is $7,693, which I cannot afford, especially on top of my car payment, which I still owe a good chunk on.

My engine failed while driving on a highway. The engine began ticking, and then completely failed. The tow truck driver reported oil leakage. I towed it to a mechanic and he said it was completely blown and irreparable. He reported this as a recurring problem with hyundai and kia cars that "eat up oil" and then damage the engine. The oil light has not been on, I've gotten regular oil changes and was within the distance of my most recent oil change. But apparently it was leaking, failed to inform me and now I have to purchase a new car or pay for a new engine. I looked up recalls, there are none. I looked up class action settlements and my car was mysteriously not on the list based on the VIN, despite being listed within the model and year range.

End of April/beginning of may, driving down highway check engine light flashing loud knocking and loss of power. Got it towed by AAA. Wasnt able to make appt until May 9th. Got it towed to the Hyundai dealership. Got phone call that is filed the bearing test and need a total engine replacement. Was told by the dealership that it could take 3 months or more to get an engine in and get it replaced. They have no loaners, and hyundai expeacts me to pay out of pocket for a rental for work to keep my job as well as my independent contracting job accounting/taxes. I have to have a vehicle. A rental is easily 1200+ a month. Hyundai refuses to give me a trade in value for my vehicle until the new engine is in. Hyundai also refunded to reimbursement me for a rental until all work is completed and a work order is in hand ( which can be many many months) I dont have money to pay 1200+ a month for a rental and also pay by car payment every month for a vehicle that is stuck at the dealership undrivable because Hyundai installed faulty bad engines. I am stuck and all Hyundai can tell me is that it takes months for the engines. Purchased the vehicle in Feb 2022 and have perfect maintance records, service records and everything else for upkeep. Still owe 15545 on the vehicle and its undrivable. So im paying a car payment on a vehicle that Hyundai made undrivable

KSDS engine software update was performed by Hyundai dealer on January 22, 2024. On or about February 11, 2024, the vehicle began stalling, intermittently, and would not restart for several minutes. On March 4, 2024, the vehicle stalled and, upon restarting, after nearly a 30 minute wait, it would not exceed 35 mph. The vehicle registered, nor recorded, any diagnostic codes at any time, during these events. The vehicle was taken to Edwards Hyundai service center for diagnosis and repair. No diagnostic codes were recorded in the vehicle history. Upon inspection, Edwards changed a loose timing chain and exhaust camshaft. The vehicle was picked up on 3/13/2024 and presented with the same issue on 3/14/2024, with the engine stalling and failing to restart for several minutes. When the vehicle did restart, it would not exceed 35 mph. It was then returned to Edwards Hyundai on 3/15/2024, where it duplicated the issue for Service Writers, failed to restart, and had to be pushed out of the service garage. The vehicle has since, without further diagnosis or repair, started and ran for technicians, who have since supposedly driven, approximately, 200 miles, in an effort to determine the issue. Edwards Hyundai then demanded the return of a loaner vehicle, in an effort to force us to retake possession of the vehicle, having failed to properly diagnose or repair the issue. A complaint has been filed with Hyundai corporate, which resulted only in them also trying to convince us to accept return of the vehicle in said state of disrepair. It has since become very clear, as evidenced by numerous reports of Hyundai vehicles experiencing the same effects and mechanical issues, after receiving the KSDS software update, that Hyundai, both at the corporate and service level, have been dishonest, as to being unaware of the cause of the issue and what must be done to resolve it. Given that the potential end result of the customer retaking possession of the vehicle in its

My vehicle had been in the shop for 30 day due to engine shutdown in the middle of the road, I barely was able to get vehicle off the road and avoid oncoming traffic. I got my vehicle back and driven it a total of 40 minutes within a 3 day time period. During my drive to work my vehicle shut off in the middle of the highway and would not turn on again. My concerns are not being taken seriously with Hyundai and it is a disaster waiting to happen. I have a one year old daughter and I can not risk her safety as well as the other on-coming people on the road when it quits and oncoming traffic has to swerve to not T-bone me. Hyundai will not take any action to correct this other than giving it a temporary fix of a 45 minute drive before they allow me to get back on the road and put myself and others at risk of injury.

NHTSA investigations
1DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
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.
