2013 Hyundai Sonata recalls and problems

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 as…

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…

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 Recor…

The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect.  During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW.  The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications.  The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU.  In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment.  FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle.  Other FCA vehicles…

During this Preliminary Evaluation (PE), the Office of Defects Investigation (ODI) assessed the scope, frequency and potential safety-related consequences of non-crash vehicle fires caused by both engine failures and failures of other vehicle systems/components in model year (MY) 2011-2014 Hyundai Sonata and Santa Fe vehicles equipped with Theta II and Lambda II engines (approximately 1.3 million vehicles). ODI also reviewed field data of other Hyundai vehicles equipped with Theta II, Gamma, Nu and Lambda engines (approximately 4.8 million). As a result of this PE, Hyundai has issued NHTSA Recalls 20V-746 and 21V-727 to address potential engine failures and fires in certain Hyundai vehicles equipped with various engine types. Additional information on these and other related recall actions is available in the downloadable version of this resume available at NHTSA.gov. In addition, ODI has upgraded this PE to an Engineering Analysis (EA) 21-003 which will focus on potential recall scope concerns and recall remedy concerns related to the engine failure rewlated recalls mentioned above and conducted previously. See the EA21-003 Opening Resume available at NHTSA.gov for more information. Also available in the downloadable version of this resume is a list of the reference numbers for the 302 ODI reports, or Vehicle Owner Questionnaires (VOQs), cited above which ODI received through mid-November 2021. Note that the Manufacturer reports cited above are customer complaints received t…

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: Reca…

The Office of Defects Investigation (ODI) opened PE18-003 on 3/16/18 to investigate incidents involving crashes, resulting in significant collision related damage, where the frontal airbags failed to deploy. ODI reviewed complaint data, available design, test, and field data on the model year (MY) 2011 Hyundai Sonata, MY 2012-2013 Kia Forte and Forte Koup vehicles. ODI also evaluated data from the automotive air bag system supplier, ZF-TRW (ZF), to review vehicles that may contain the same air bag control unit (ACU) used in the subject vehicles. Hyundai Motor America (HMA) issued recall No. 18V-137 for MY 2011-2013 Sonata and MY 2012 Sonata Hybrid vehicles. Kia Motors America (KMA) issued recall No. 18V-363 for MY 2010-2013 Kia Forte and Forte Koup, MY 2011-2013 Optima, MY 2011-2012 Optima Hybrid, and MY2011-2012 Sedona vehicles. The two recalls address vehicles containing ACUs manufactured without adequate circuit protection by installing a wire harness filter kit to prevent internal damage to the ACU. In the event of a crash, ACU damage may result in the disablement of the vehicle's airbags. Each respective manufacturer has mailed letters to affected vehicle owners informing them of the remedy and its availability. ODI plans to evaluate the susceptibility of the subject ACU to electrical signals, as well as other vehicle factors that can either lead to, or reduce the likelihood of, an electrical overstress event in other vehicles manufactured with the subject ZF ACU.Accordi…

NHTSA opened Recall Query (RQ) 17-004 to investigate the timeliness and scope of Hyundai?s Theta II GDI engine recalls (Recall Nos. 15V-568 and 17V-226), and Hyundai?s compliance with reporting requirements. On November 23, 2020, the Agency entered into a Consent Order with Hyundai to administratively resolve NHTSA?s assertions of violations of law in connection with RQ17-004. NHTSA?s assertions included that Hyundai may be liable for civil penalties on multiple grounds, including the untimeliness of Recall Nos. 15V-568 and 17V-226, inaccuracies in Hyundai?s recall reports, and that a required report describing potential safety-related issues contained certain inaccuracies or omissions.Under the Consent Order, Hyundai agreed to a total civil penalty of $140,000,000. The total civil penalty included payment of $54,000,000 as a Non-Deferred Amount. Hyundai also agreed to a sum of $46,000,000 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.Additionally, Hyundai agreed to a $40,000,000 Performance Obligation Amount to be expended by Hyundai to fulfill specified Safety Data Analytics Infrastructure obligations and Test and Inspection Laboratory obligations. The Consent Order also includes other terms designed to enhance Hyundai?s safety practices, and requires Hyundai to retain a Third-Party Auditor who directly reports to NHTSA.Other than RQ17-004, the Consen…

The Office of Defects Investigation (ODI) opened this investigation on December 27, 2016 based on two ODI consumer complaints reporting a failure of the front passenger seat belt to remain connected to the seat belt anchor and pre-tensioner during a crash.On March 8, 2017 Hyundai Motor America (Hyundai) filed a defect report with the agency stating that it would conduct a safety recall on 977,778 model year 2010-2014 Sonata vehicles produced from December 11, 2009 through May 29, 2014 and model year 2011-2015 Sonata Hybrid vehicles produced from December 2, 2010 through January 9, 2015.The remedy for the recall was to inspect the front seat belt anchor connector for proper attachment to the seat belt pre-tensioner.ODI continued the investigation in order to pursue a remedy that would be more lasting, rather than a one-time inspection.The connector is designed so that it can be removed from the pre-tensioner, when required, during vehicle maintenance.If it is not properly connected when originally installed or when re-installed after maintenance, the connector could potentially release in a crash. On September 4, 2017 Hyundai filed an amended defect report and advised the agency that the remedy would be modified to provide a permanent label, to be attached to the connector, at the time of inspection.The label provides graphic instructions and illustration as to the proper orientation of the connector lock when it is properly installed.On October 4, 2017 Hyundai filed an additi…
