Loss of Motive PowerOpened September 12, 2022, closed December 12, 2023

the federal safety agency 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 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 the federal safety agency 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 the federal safety agency's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, the federal safety agency does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing the federal safety agency’s reasons for denial of the petition will be published. The reference numbers for the complaints to the federal safety agency 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

DP22003

Engine FiresOpened December 22, 2021, closed February 5, 2024

On March 29, 2019, the Office of Defects Investigation (ODI) opened two Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) to broadly investigate incidents of non-crash fires (regardless of origin or operational status of the vehicle) on various model year Hyundai and Kia vehicles. During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types. The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine replacement. Additionally, both manufacturers have been installing an engine control software modification known as Knock Sensor Detection Software (KSDS) which is intended to detect impending engine failure, alert the driver, and limit engine power (to lessen likelihood of engine failure).KSDS is being installed under recalls and non-safety field actions, and both companies have extended limited engine warranties (see recall files). On December 22, 2021, ODI upgraded PE19-003 and PE19-004 to this Engineering Analysis (EA21-003, covering both Hyundai and Kia) to evaluate the scope of the prior recalls related to engine failures/fires and the efficacy of the recall remedies for the recalls, as well as the long-term viability of related programs and non-safety field actions being conducted by Hyundai and Kia. The former issue involved approximately 550,000 MY 2013 Hyundai Elantra, MY 2011 Kia Sorento, and MY 2012-2015 Kia Rio. The latter issue involved approximately 2.5 million recalled vehicles, which have been identified as displaying potential remedy concerns: Hyundai recalls 15V‑568, 17V‑226, 20V‑746, and 21V‑727; and Kia recalls 17V‑224, 19V‑120, 20V‑750, and 21V‑844. Regarding the recall scope issue, among all of the scope vehicles identified at EA opening, ODI found only the MY 2011 Kia Sorento vehicles equipped with both the Theta II 2.4L 4-cylinder Multi-Point Injection (MPI) and the Lambda II 3.5L 6-cylinder MPI engines experienced relatively high rates of reported fires. In December 2023, Kia issued recall 23V‑877 that will cover about 80,000 MY 2011 Kia Sorento vehicles equipped with the Theta II 2.4L MPI engines.  The remedy will involve an inspection, and if necessary, a replacement of the engine, as well as the installation of KSDS.  It should be noted that in 2021 these vehicles were included in a KSDS product improvement campaign with warranty extension. For the MY 2011 Sorento vehicles equipped with the Lambda II 3.5L engines, ODI believes that future engine failures/fires involving these vehicles will likely be due to a lax in adhering to the proper or scheduled engine maintenance (regular engine oil changes), rather than a design or manufacturing engine issue. Regarding the issue of the efficacy of the recall remedies, ODI found the majority of the recalled Hyundai and Kia vehicles, by model, experienced lower reported fire rates after the remedies were applied. Furthermore, ODI found that for most vehicles that did not receive the recall remedies, by model, experienced relatively high fire rates. To address this problem, Hyundai informed ODI in December 2023, that it will renotify all of its owners covered by the Hyundai recalls of engine failures/fires every 8 months for the next 3 years. In December 2023, Kia stated that it will renotify the majority of its owners every 8 months for the next 3 years.Several previously recalled Kia models are excluded from the renotification due to their lower reported rates of engine fires. Overall, the renotification actions will help to increase the recall completion rates, thus reduce the frequency of engine fires in the future. In view of the recall action being taken by Kia and renotification actions being taken by both Kia and Hyundai, ODI is closing this Engineering Analysis. Also, both companies have been released from the 2020-iniated Consent Orders (Kia since November 2022 and Hyundai since November 2023). The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to

While driving, engine made a sound like a ticking noise then just blew. Oil all over the engine bay and ground. A lot of smoke coming from under the hood. Would not start or do anything.

I heard a knock coming from the engine and suddenly the car died while driving in the city the check engine light came on and would not start up again but the power was still on for lights, etc. I had to have it towed to the repair shop. I was told the engine is shot. After researching the kia forte I found a lot of reviews complaining of the same thing on the 2012 forte. Now with the recalls for the other kia engines with the same or similar engine types, this make and model needs to be included!!!

While driving this car, I heard a knock coming from the engine!! I had it towed to a kia dealer and was told that I needed a new engine! This is unacceptable for car that is only 6 years old and all maintenance kept up to date!! I did some checking and other kia engines with similar or same engine types have been recalled. This make and model needs to included!!

I was turning left and car chugged back and forth and burning smell with a ton of gray and white smoke pouring out of back of car. Fought with kia got a rebuilt engine. 2 weeks later same problem. Took back to a different dealer and faulty valve was never replaced. Happened again 3 weeks later. Can't find anything wrong. Happened again 3 weeks later and this time smoke and burning smell was so intense you couldn't see in back of car. Dealership said that I just need to drive it more. I am a mother to 3 young kids. The car smells like it's going to explode and the smoke alone is dangerous to who is behind me.

On 7/23/2016(milage 108000) I was driving my 2012 kia forte sx koup to work traveling 70 MPH on the highway. 2 miles from work I began to hear a loud knocking sound . Arriving at work I did a quick engine inspection but could not find anything visually wrong (leaks, smoke, loose parts) later that morning I returned to my car to test the engine and could hear the same noise. I decided it would be best to have it towed to a mechanic. Vehicle was not inspected until 07/25/16. Mechanic said the engine needed to be replaced after discovering a bad rod. Mechanic also contacted kia to see if by chance they would offer and extended warranty, but kia would not repair engine since it had passed the 100000 mile warranty. (just 8000 miles over warranty !!!!!!) my wife and I decided to bite the bullet and have the engine repaired. $4300 and one week later my vehicle was returned to me. I now see all of these news stories about kia catching fire and other horror stories on the federal safety agency website about the same experience others have gone through . I am even more outraged that it could still happen to me and the fact that there is a current recall for the airbags and seat belts but not the engine!!!!!!!!!!! Please do something!!!!!!

I am the original owner of a 2012 kia forte koup sx with the 2.4 liter theta ii engine that is being recalled on a limited basis by kia under the federal safety agency sc147. A week while merging with faster traffic my engine died forcing me into a very dangerous situation trying to cross several lanes of much faster moving traffic with a dead engine. I came to a stop in the center lane and had several very close calls before other vehicles had to swerve at the last second to avoid hitting me. Much like the countless other examples of vehicles equipped with the theta ii engine seizing or spinning rod bearings my engine seized solid even though I meticously followed the prescribed maintenance intervals kia suggests. After doing a little research I was dismayed to see how wide spread this issue is and cannot fathom why kia is permitted to only recall some vehicles with this same engine and not others. I very strenuously urge the federal safety agency to expand upon recall sc147 to include all vehicles with this engine before other injuries or deaths occur as I could have very easily sustained. There should be no excuse and no defending of kia's position that this engine only fails due to manufacturing flaws on some models and not others models when they both use the same engine when all one must do is to do a quick google search to see countless examples of american consumers being left without assistance to face the manufacturer to get these issues resolved. It is yet to be seen if kia appropriately make all necessary repairs to my vehicle either under the 10 year/100,000 mile limited warranty (my vehicle is 6 years old with 80,000 miles) or under recall sc147; however, based upon what I repeatedly am finding, kia will try denying repairs, demanding all maintenance receipts and generally making it as difficult as possible for consumers to get warranty work done.
