Six weeks ago the alternator and battery had also been replaced. My Hyundai Santa Fe Sport turbo engine, exhibited a persistent rubber-like odor for approximately three weeks after the latest maintenance. During this period, the push-start button intermittently failed, requiring multiple attempts to engage, and the vehicle experienced noticeable shaking. After being parked, smoke began to emerge from under the hood, followed by visible flames. Within roughly 3-5mins minutes, the vehicle was completely engulfed in fire and blew up 6 times. Notably, the car had undergone significant repairs in the past year, including an engine replacement, starter, OEM parts, O2 sensors, brakes, valve cover gasket, new tires, and routine oil changes.

September 3rd, 2025, my engine failed, for the second time and left me stuck at a busy intersection, in the middle lane and can't move. The first time my engine failed (2022/same vehicle), I was about the get on the highway and it just stopped in the middle of the road right before getting onto the highway. Both times I've had to get out in traffic in order to move my vehicle. I'm causing a stop to traffic or a stop in the flow of traffic. In September when this happened, I had cops, mechanics and pedestrians stopping to help (thank goodness), but that caused a stop in the flow of traffic. Any of us could have been struck by a vehicle. It was also around 10/11pm at night There is an open recall on my vehicle and more specifically, the Theta II engine in my vehicle. It does not show when my VIN number is put in, but it's nationally known that there is an open recall and also a class action suit that was just settled in 2021 granting all customers with "Class vehicles" a lifetime extended warranty on the engines. They make it so that it's not that easy to just search and see there is a recall, but there is. My car has been at the Hyundai dealership since 9/4/25. So, yes it has been inspected by the manufacturer, and they confirmed that the diagnostic came back as positive for the recall. Yes, my check engine light would come on and off starting the end of 2024. Starting in April of 2025 I started having smoke come out of my exhaust and oil burning in days. All the while I have no puddle of oil underneath my car. I took it into Hyundai at that point, and they told me until my engine light was flashing and my car had stopped, they wouldn't be able to do anything in regard to the engine. Now my car has been there, I've provided service receipts that show proof of regular maintenance, I have the KSDS system installed, and they are denying my claim to replace my engine.

There was no low oil indicator light, no smoke, and no oil on the garage floor. My wife was driving the vehicle on I-285 in Atlanta, returning from the ATL airport, when the vehicle began to lose power and started jerking and surging; the check engine light began flashing. She had to take surface streets to get home because the loss of power made the vehicle unsafe to drive on the freeway. When she arrived home, I checked the engine oil dipstick and it was completely dry. I took the vehicle to the garage that performs my oil changes, and they mentioned this is an ongoing issue with Hyundai—the vehicle is burning oil. The low oil level caused the knock sensor to trigger, which in turn caused the check engine light to flash and reduced power in an attempt to protect the engine. I never received any notification regarding a recall for this issue, and now my motor is more than likely damaged since I can still hear knocking when the engine runs at higher RPMs. My vehicle has over 100K miles, and I have never had an issue with it until now.

Engine siezed, causing me to have to tow my vehicle. I was moved in the military to Germany in 2019, I had to have no open recalls on the car before I shipped it overseas. I completed a recall on the 5th of January 2019. On the 10th of January, Hyundai activated another recall on the vehicle. I was unaware of this recall and shipped my vehicle to Germany on the 16th of January 2016. The car returned from Germany in September of 2023. I had zero issues with this vehicle while I was over there, no check engine lights, no warning lights, nothing. I always changed the oil when told to do so, and when I returned from Germany it was the same thing, no issues and always completed oil changes when it was needed. I had no idea of the recall, Hyundai was sending it to an address I no longer lived at. I had no reason to take my vehicle to Hyundai to check for recalls. On [XXX], my vehicle engine stopped working at 84622 miles, and Hyundai said that it would be covered under warranty, but because I did not complete the recall that was activated on the 10th of January 2019, they denied the warranty and now my car is worthless.

Subject: Engine Failure Due to Bearing Defect – No KSDS Recall Notification Vehicle: 2016 Hyundai Santa Fe Sport VIN: [XXX] Date of Purchase: April 2016 Complaint Summary: I am filing this complaint regarding my 2016 Hyundai Santa Fe Sport, which experienced catastrophic engine failure due to the known Theta II GDI engine bearing defect. Hyundai has an active class action settlement covering this defect, which requires owners to install the Knock Sensor Detection System (KSDS) update to be eligible for free repairs or the lifetime warranty. Despite owning my vehicle since April 2016 and holding clear title in my name for over 6 years, I never received any notice or communication about this required software update. Hyundai’s records still list the prior owner, Hertz, even though I have maintained valid registration and insurance in my name since the purchase. This lack of notice prevented me from having the KSDS update installed before the engine failed. I understand this defect does not show as an open safety recall on the NHTSA database because Hyundai classified it as a Product Improvement Campaign under the class action settlement. This does not change the fact that it is a known safety hazard and Hyundai failed to properly notify me, which denied me the chance to protect myself and my vehicle. I believe this is a major safety concern because the engine can stall or catch fire without warning. I am requesting that NHTSA hold Hyundai accountable for failing to properly notify current owners and ensure compliance with the class action settlement. Desired Resolution: Require Hyundai to honor the warranty and cover my engine replacement in full. Investigate whether Hyundai is failing to properly notify owners about this critical software update. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

DP22003 · 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.
