An investigation means NHTSA has decided a pattern is worth examining. A
preliminary evaluation is often closed with no action; an engineering
analysis is the stage that usually precedes a recall.
Hyundai and Kia ABS Module Fires
AQ23002
Still open audit query · opened November 17, 2023
the hydraulic brakes
The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651. Kia recalls 16V-815, 20V-518, 20V-519, 21V-137, 21V-331, 22V-051, 22V-800, and 23V-652 The purpose of this AQ is to evaluate the timeliness and scoping of Hyundai and Kia’s defect decision making and adherence with reporting requirements; and understand the varying defect descriptions and remedies between these recalls.
Throttle control system vulnerabilities
DP21003
Closed defect petition · opened November 12, 2021 · closed June 20, 2023
vehicle speed control
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.
Headliner Bracket Detachment
EA12008
Closed engineering analysis · opened September 13, 2012 · closed December 9, 2013 · led to recall 13V115000
the air bags, the body structure, unknown or other
In March 2013, Hyundai issued a safety recall to reinforce the attachment of the metal support brackets to the headliner assembly in approximately 186,254 model year 2011-2013 Hyundai Elantra vehicles built in Korea and sold in the U.S. (see NHTSA recall 13V-115 for more information).The recall covers vehicles built up to March 5, 2013.After that date, Hyundai began using headliners with reinforced bracket attachments in the Korea-built Elantra vehicles.ODI has opened a Recall Query (RQ13-004) to investigate model year 2009-2012 Hyundai Elantra Touring vehicles.During EA12-008, ODI found these vehicles are equipped with a support bracket design and layout similar to that in the above-mentioned Elantra vehicles.Also, the headliner manufacturing processes used were similar for both models.Like the Elantra vehicles built before the recall, the Elantra Touring model headliner does not contain reinforced bracket attachments.This Engineering Analysis is closed.See attached report for additional information.The ODI report cited above can be reviewed online at http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification number: 10457696
Side Curtain Air Bag Improper Deployment
PE12012
Closed preliminary evaluation · opened May 10, 2012 · closed September 17, 2012
the air bags
The Office of Defects Investigation (ODI) is aware of one incident of an improper deployment of the driver-side curtain air bag that deployed as a result of a crash involving a model year (MY) 2012 Hyundai Elantra.An inspection of this vehicle showed that a metal bracket (stiffener) in the headliner assembly had detached and was forced downward by the deploying air bag.The metal bracket caused a laceration to the driver's ear and other possible injuries.Approximately 75,000 MY 2012 Hyundai Elantra vehicles, built in Korea and sold in the U.S., have stiffeners in the headliners while the MY 2012 Elantra vehicles built in the U.S. utilize a different headliner that does not use a stiffener. Thus, the latter vehicles are not included in this investigation.Hyundai has inspected the headliner assemblies from eight Elantra vehicles (which were sold in the Korean market) with production dates in the same range as the field incident vehicle.Hyundai reported to ODI that the metal brackets from these vehicles were found to be securely attached to the headliners.Hyundai also has conducted several static deployment tests in attempts to replicate the field incident. In one test, the metal bracket detached from the headliner but the test condition did not replicate or explain the condition observed in the incident vehicle.This Preliminary Evaluation has been upgraded to an Engineering Analysis (EA12-008) to further assess whether incidents like the single field incident could potentially occur with other subject vehicles.In addition to the subject vehicles, ODI also will collect and review information on MY 2011 and 2013 Elantra vehicles that have headliners with stiffeners similar to those in the subject vehicles. To date, there have been no reports on the MY 2011 and 2013 vehicles.The ODI report cited above can be viewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification number: 10457696
