    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: Scope and Timeliness

    NHTSA Defect Investigation #RQ17004

    • Status:
    • Date Opened: May 18, 2017
    • Date Closed: N/A
    • Recall: No recall yet

    Component(s): Engine

    Summary: On September 10, 2015, Hyundai Motor America (Hyundai) filed a Defect Information Report (DIR) recalling 470,000 MY 2011 and 2012 Sonata vehicles with ""Theta II" engines (Recall No. 15V-568). Hyundai's DIR described the defect as an issue involving manufacturing debris. Hyundai limited the population of recalled vehicles to those produced on or prior to April 12, 2012, stating that a process change in April 2012 resolved the issue of manufacturing debris. On March 31, 2017, Hyundai expanded its original recall to include 572,000 MY 2013-2014 Sonata and Santa Fe Sport vehicles with "Theta II" engines (Recall No. 17V-226). The DIR continues to describe the defect as an issue involving manufacturing debris.This RQ is being opened to investigate both the timeliness and scope of Hyundai's "Theta II" engine recalls, and Hyundai's compliance with reporting requirements.

  3. INVESTIGATION: Front Axle Shaft Failure

    NHTSA Preliminary Evaluation #PE13025

    Component(s): Power Train
    Power Train:Axle Assembly:Axle Shaft

    Summary: In a letter dated August 9, 2013, Hyundai-Kia America Technical Center, Inc. (Hyundai-Kia) submitted two Defect Information Reports (DIR) to NHTSA identifying a safety defect related to fracture of the right front axle shaft in MY 2013 front wheel drive Hyundai Santa Fe Sport vehicles built from July 13, 2012 through March 12, 2013 and MY 2014 front wheel drive Kia Sorento vehicles built from January 7 through March 12, 2013 (Recall Nos. 13V-355 and 13V-356).According to Hyundai-Kia, the right front axle driveshaft may develop a crack in the area of the stub at the wheel end of the shaft due to problems with the stub supplier's forging process for axles installed in vehicles built prior to March 12, 2013.When moving from a stop, the crack can lead to a separation of the shaft, causing a loud noise and loss of motive power.In addition, should the driver fail to engage the parking brake on an inclined surface, the vehicle may roll.In either case, a crash could result.ODI's review of consumer complaints and data submitted by Hyundai-Kia, identified 21 complaints alleging right-front axle shaft failure and 60 warranty claims related to right front axle replacements.All of the vehicles identified in the complaints and warranty claims were manufactured during the vehicle builds periods identified in the DIR.The Preliminary Evaluation is closed.The ODI report cited above can be reviewed at under the following identification (ODI) numbers: 10524563, 10524274, 10508727, and 10505768.
