    Summary: On June 11, 2018, the Center for Auto Safety (CAS) petitioned NHTSA to conduct a defect investigation into non-crash fires on model year 2011-2014 Kia Optima and Sorento, and Hyundai Sonata and Santa Fe vehicles.The CAS petition cited at least 120 Vehicle Owner Questionnaire (VOQ) reports of fires and additional 229 VOQs of melted wires, smoke and/or burning odors, indicating potential fires on these vehicles, as of June 7, 2018.ODI's preliminary review of the VOQs indicates the majority of the reported fires appears to be related to the engine failures covered by two current Recall Queries: RQ17-003 on Kia vehicles and RQ17-004 on Hyundai vehicles.ODI is opening a Defect Petition to review the petition, VOQs, Early Warning Data, and other information on the subject vehicles followed by a decision to grant or deny the petition.The following VOQ numbers (120 fire reports) are cited by the petitioner and can be viewed at 10386128 10398744 10429442 10436180 10441602 10465924 10476823 10482868 10503081 10534292 10547548 10553823 10555125 10558870 10560485 10572612 10587361 10645013 10650571 10661186 10692124 10693248 10694186 10702294 10705662 10714982 10726832 10748707 10748982 10779962 10783067 10785478 10786603 10787041 10787681 10806151 10806344 10808477 10812040 10821034 10824280 10846035 10850516 10852467 10861488 10873251 10883323 10884112 10892633 10894943 10895904 10901907 10903380 10903804 10905594 10914540 10918948 10920235 10926855 10930342 10938549 10949004 10957216 10958524 10965933 10968692 10970145 10971800 10972006 10978698 10980295 10984187 10985144 10991332 10991353 10991729 11005870 11010849 11012450 11012531 11012907 11013481 11015550 11015830 11016078 11016332 11022683 11022912 11024053 11031971 11043333 11044183 11045499 11047022 11052937 11057393 11058273 11060659 11062637 11065937 11066433 11066583 11071675 11073341 11074148 11075310 11076296 11080980 11081758 11082829 11090028 11090119 11090295 11091115 11093994 11097211 11097793 11097934 11098807

  2. INVESTIGATION: Steering Shaft Universal Joint Failure

    NHTSA Preliminary Evaluation #PE12029

    • Status:
    • Date Opened: October 09, 2012
    • Date Closed: June 26, 2013
    • Recall: No recall issued

    Component(s): Steering:Column

    Summary: The Office of Defects Investigation (ODI) opened PE12-029 based on one complaint alleging that a fastener became loose in the steering shaft of a model year (MY) 2011 Hyundai Santa Fe vehicle and related Early Warning Reporting field report data.In it's response to ODI's information request letter for PE12-029, Hyundai identified a total of four incidents of steering shaft universal joint failure in early production MY 2011 Santa Fe vehicles, including the incidents that had been identified by ODI. Two of the failures occurred at low mileage early in 2011, shortly after vehicle sale, leading to Hyundai's initial investigation.Hyundai attributed the failures to operator error at the vehicle assembly plant in failing to fully assemble the universal joint to the steering column shaft before tightening the universal pinch bolt.The company inspected 680 vehicles at the assembly plant as part of its initial investigation and found no additional indications of improper steering shaft assembly. Hyundai implemented changes in the assembly process to ensure proper steering shaft assembly, including the use of a "go/no go" Gap Gauge to ensure that the universal joint knuckle is fully assembled to the steering column shaft before being fastened.Hyundai believes that the improper assembly affected only a few vehicles and that joints that were not properly assembled should have already failed and the likelihood of additional failures is remote.None of the failures involved vehicles produced after the Gap Gauge implementation on April 27, 2011 and no additional failures have been reported since October 2012.Hyundai will notify ODI if any additional failures are reported to the company through the end of 2013.A safety-related defect trend has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will take further action if warranted by the circumstances.
