WE WERE DRIVING ON THE HIGHWAY WHEN WE NOTICED THE TEMPERATURE GAUGE GOING UP. WE STOPPED AT A SHOP AND GOT IT LOOKED AT AND THEY REPLACED THE THERMOSTAT AND FLUSHED THE RADIATOR. ON THE HIGHWAY ON THE WAY HOME WE NOTICED THE TEMPERATURE GAUGE GOING BACK UP AND PULLED OVER. WE HAD IT TOWED HOME. WE AGAIN MADE THE REPAIRS AND THEN TOOK IT TO THE KIA DEALERSHIP FOR THEM TO LOOK IT OVER AND HAVE ANY NECESSARY REPAIRS DONE AND PAID BY THE WARRANTY WE HAVE ON THE SORRENTO. THE DEALERSHIP HOOKED UP THE VEHICLE TO CHECK THE FREE STREAM DATA FAULT CODES BUT NON WERE PRESENT. OUR SORRENTO GOT HOT ENOUGH TO WARP THE ENGINE HEADS AND REQUIRE A NEW ENGINE BUT NEVER ONCE DID IT TRIP A CODE/WARNING LIGHT ON THE DASH. IF IT HADN'T BEEN FOR US NOTICING THE TEMPERATURE GAUGE GOING UP WE WOULD HAVE HAD NO WARNING THAT OUR CAR WAS OVERHEATED TO THE POINT THE RADIATOR BOILED OVER AND WARPED THE ENGINE HEADS. WHY WASN'T ANY WARNING LIGHT SUCH AS CHECK ENGINE LIGHT OR ANYTHING SIGNALED TO COME ON?

THE END OF OCTOBER 2018 MY 2014 KIA SORENTO MOTOR BLEW UP. WE HEARD THE KNOCKING ON A WEEKEND, KIA SAID TO BRING IT IN AND IT STALLED HALFWAY THERE. HAD TO CALL MY INSURANCE BECAUSE KIA WOULD NOT PAY FOR TOWING. MY KIA HAD BEEN CHECKED THE YEAR BEFORE FOR THE ENGINE RECALL, OF COURSE IT PASSED. IT TOOK 2 MONTHS TO GET MY CAR BACK, THEY DID PROVIDE A RENTAL. A MONTH LATER (JAN. 2019) I SMELLED GASOLINE VERY STRONG IN MY CAR. HAD MY HUSBAND TEST DRIVE IT TO MAKE SURE THAT IS WHAT IT WAS BECAUSE I HAD JUST PUT IN A FULL TANK OF GAS. SURE ENOUGH I CALLED WARNER KIA OF PARKERSBURG AGAIN, ONCE AGAIN REFUSED TOWING EVEN THOUGH I ALREADY KNEW ABOUT THE ISSUE WITH THE FUEL LINES FROM THE ENGINE REPLACEMENT. I HAD TO CALL KIA CONSUMER AFFAIRS TO GET THIS CAR TOWED TO WARNER KIA. TURNS OUT THEY FORGOT TO REPLACE A BRACKET DURING THE ENGINE REPLACEMENT, NOT VERY SMART IN MY OPINION FOR SO CALLED CERTIFIED MECHANICS. I GOT IT BACK AGAIN FEB. 2019. NOW IT IS MARCH 2019, MY TRANSMISSION APPEARS TO BE SLIPPING, HESITATING TO PICK UP SPEED. I ALMOST GOT HIT BY A SEMI TRYING TO GET ONTO THE INTERSTATE BECAUSE CAR WOULD NOT GO FAST ENOUGH. MY UNCLE TRIED TO SEE IF HE COULD CHECK MY TRANSMISSION FLUID AND OF COURSE IT IS ENCASED, BUT WHILE DOING THIS HE NOTICED THE ENGINE COOLANT WAS VERY LOW. THE LEVEL IS BELOW L. MY ENGINE WAS JUST REPLACED NOT TOO LONG AGO AND IT WAS IN THE SHOP AGAIN FOR MORE WORK JUST LAST MONTH. I AM BEYOND FRUSTRATED. I HAVE MADE CONCERNS WITH KIA CONSUMER AFFAIRS AND HAVE NOT GOTTEN ANYWHERE. I WILL OWE ON THIS CAR FOR ANOTHER 2 YEARS AND IT LOOKS LIKE IT WON'T LAST. ALSO UPSIDE DOWN ON LOAN. NOW I AM SCARED THAT MY CAR WILL CATCH ON FIRE OR CAUSE AN ACCIDENT WITH MY CHILDREN IN MY CAR ALL BECAUSE KIA CAN NOT MAKE BETTER VEHICLES OR AT LEAST TRY TO REIMBURSE THEIR CUSTOMERS TO KEEP THEM HAPPY. I WANT A NEW CAR, AND I WANT KIA TO PAY FOR IT AND OTHERS VEHICLES.

I TOOK THE CAR TO THE KIA DEALERSHIP AND THEY TELL ME THE ENGINE HAS AN OIL LEAK. I BELIEVE THEIR KIAS SPORTAGE 2011 & 2012 WERE ALSO RECALLED FOR THE SAME ISSUE. THE CAR HAS LESS THAN 100,000 MILES ON IT AND I HAVE OWNED SEVERAL CARS BEFORE AND NEVER HAD AN OIL LEAK ON THE ENGINE AT ALL. THEY SAID THE REPAIRS WERE GOING TO COST OVER $1000 TO REPAIR. I BELIEVE THIS CAR SHOULD ALSO BE RECALLED DUE THAT THEY HAVE A HISTORY OF OTHER MODELS HAVING THE SAME PROBLEM. THANK YOU.

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.

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. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

DP21003 · Throttle Control System Vulnerabilities

Opened Nov 12, 2021 · Closed Jun 20, 2023

Status: closed (inferred from source dates) · Vehicle Speed Control:throttle

The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.

In a letter dated June 11, 2018, the Center for Auto Safety (CAS) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a safety defect investigation into non-collision related fires on model year (MY) 2011-2014 Kia Optima and Sorento, and Hyundai Sonata and Santa Fe vehicles. In a letter dated July 24, 2018, CAS requested that MY 2010-2015 Kia Soul vehicles be added to the petition. CAS stated that there is a higher number of complaints to NHTSA regarding non-crash fires on these vehicles compared to other similar vehicles. The Office of Defects Investigation (ODI) had already opened Recall Queries (RQ17-003 and RQ17-004) on all Kia and Hyundai vehicles equipped with Theta II engines for engine failures that may cause stalling and fires.The queries cover most of the petition subject Optima, Sorento, Sonata, and Santa Fe vehicles but not any of the subject Soul vehicles.On August 21, 2018, ODI opened a Defect Petition (DP18-003) to evaluate whether to grant or deny the CAS petition. ODI sent Information Request letters to Kia and Hyundai (September and October 2018) requesting information on all engine and non-engine related fires in the petition vehicles.ODI performed extensive analysis on the information obtained from Kia and Hyundai. During the DP18-003 analysis, Kia and Hyundai each initiated three additional safety recalls related to engine compartment fires on certain petitioned and non-petitioned vehicles (nearly 740,000 total vehicles: Recalls 18V-907, 18V-934, 19V-101, 19V-063, 19V-120, and 19V-204). Based on ODI?s review of the applicable materials, including responses to Information Requests sent to multiple manufacturers, Vehicle Owner Questionnaires (VOQ), and Early Warning Data, NHTSA decided to grant the petition.The CAS petition was granted on March 29, 2019. Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) have been opened to assess the scope, frequency, and potential safety-related consequences of alleged defects relating to non-collision vehicle fires in the 2011-2014 Kia Optima and Sorento, 2011-2014 Hyundai Sonata and Santa Fe, and 2010-2015 Kia Soul.Attached is a list of the reference numbers for the 404 VOQs cited above.

RQ17003 · Scope And Timeliness

Opened May 18, 2017 · Closed Dec 22, 2021

Status: closed (inferred from source dates) · Engine

NHTSA opened Recall Query (RQ) 17-003 to investigate the timeliness and scope of Kia?s Theta II GDI engine recall (Recall No. 17V-224), and Kia?s compliance with reporting requirements. On November 23, 2020, the Agency entered into a Consent Order with Kia to administratively resolve NHTSA?s assertions of violations of law in connection with RQ17-003. NHTSA?s assertions included that Kia may be liable for civil penalties on multiple grounds, including that Recall No. 17V-224 was untimely and Kia?s recall report contained certain inaccuracies.Under the Consent Order, Kia agreed to a total civil penalty of $70,000,000. The total civil penalty included a payment of $27,000,000 as a Non-Deferred Amount.Kia also agreed to a sum of $27,000,000 as an Abeyance Amount to be deferred and held in abeyance pending its satisfactory completion, as reasonably determined by NHTSA, of the requirements of the Consent Order.Kia also agreed to a $16,000,000 Performance Obligation Amount to be expended by Kia to fulfill specified Safety Data Analytics Infrastructure obligations. The Consent Order also includes other terms designed to enhance Kia?s safety practices, and requires Kia to retain a Third-Party Auditor who directly reports to NHTSA.Other than RQ17-003, the Consent Order is not intended to affect any other current or future investigation of NHTSA which may involve vehicles equipped with Theta II GDI engines.
