THE CAR STATED HAVING A LIGHT KNOCKING ON AND OFF, THEN STARTED CUTTING OUT AND STUTTERING. IT PROGRESSED AND NOW THE ENGINE WILL MAKE A NOISE LIKE A DIESEL ENGINE ON AND OFF AND THE CAR WILL GO DEAD STOPPED IN TRAFFIC AND ALSO WHILE DRIVING DOWN THE ROAD OR INTERSTATE.

WE ONLY BOUGHT THIS CAR 8 MONTHS AGO WITH 70,000 MILES ON THE ENGINE. WE NOTICED THE ENGINE SEEMED TO BE LOSING POWER AFTER ABOUT 4 MONTHS. THEN LAST WEEK THE CAR ABRUPTLY SHRIEKED AND STOPPED WHILE WE WERE DRIVING. AFTER WHICH, THE ENGINE BEGAN TO KNOCK, AND WE HAD IT TOWED TO A LOCAL KIA DEALERSHIP. THE DEALERSHIP TOLD US WE WOULD NEED A NEW ENGINE AND THE KNOCK WAS COMING FROM THE LOW END. WE HAVE RELIGIOUSLY SERVICED THE VEHICLE, AND THE CAR ONLY HAD 80,000 MILES WHEN THE ENGINE BLEW. CLEARLY THIS IS A FAILURE OF THE MANUFACTURER, BUT BECAUSE WE ARE NOT THE ORIGINAL OWNERS, KIA REFUSES TO PROVIDE THE REPAIRS THEY KNOW THEY ARE RESPONSIBLE FOR.
MY FORTE'S ENGINE SEIZED AT 106,000 MILES. AS I WAS DRIVING THE ENGINE STARTED MAKING A TICKING SOUND. THE ENGINE SEIZED UP AND I WAS TOLD THEY HAVEN'T RECALLED THIS DESPITE MANY COMPLAINTS OF THIS HAPPENING TO THIS YEAR AND MAKE OF KIA.
2 MONTHS AGO WE HAD OIL CHANGED, THE VEHICLE WAS 2000 MILES FROM NEEDING NEXT ONE. IT STARTED KNOCKING & WE WERE ABLE TO GET TO MECHANIC, HE SAID IT LOOKED LIKE THE OIL HAD NOT BEEN CHANGED NEEDED OIL AND HE CLEANED THE ENGINE AND MADE SURE EVERYTHING WAS IN WORKING ORDER.

2 MONTHS AGO WE HAD OIL CHANGED, THE VEHICLE WAS 2000 MILES FROM NEEDING NEXT ONE. IT STARTED KNOCKING & WE WERE ABLE TO GET TO MECHANIC, HE SAID IT LOOKED LIKE THE OIL HAD NOT BEEN CHANGED NEEDED OIL AND HE CLEANED THE ENGINE AND MADE SURE EVERYTHING WAS IN WORKING ORDER. NO LEAKS WERE DETECTED. 1000 MILES LATER HEAR A CLANKING SOUND AND WAS ABLE TO MAKE IT IN THE DRIVEWAY AND CAR SHUT OFF. WHEN I TRIED TO START IT WOULD NOT TURN OVER AND WHEN I LOOKED UNDER HOOD THERE WAS A SPARK. LOOKED TO BE NO OIL PUT IN 2 QUARTS AND LET IT SIT OVER NIGHT. CHECKED OIL AGAIN BEFORE ADDING ANYMORE & LEVELS WERE FINE. MECHANIC SAID ENGINE WAS DONE. THE OIL IS GOING SOMEWHERE & THIS MODEL HAS A TOYOTA ENGINE, SO I THINK SOMETHING ELSE IS GOING ON. WE HAVE KEPT UP WITH ALL MAINTENANCE ON THIS VEHICLE. WE TRAVEL ALL HIGHWAY AND IT DOES HAVE 200,000 MILES ON IT. I HAVE HAD HONDAS & TOYOTAS & NO PROBLEMS. I WILL NEVER OWN ANOTHER KIA. WE DID NOT HAVE IT REPAIRED OR REPLACED & WAS TOLD BY KIA THAT THEY DO NOT MAKE THAT ENGINE ANYMORE.

2DP22003 · 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.
EA21003 · Engine Fires
Opened Dec 22, 2021 · Closed Feb 5, 2024
Status: closed (inferred from source dates) · Engine
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.
