WE PURCHASED A 2006.5 KIA OPTIMA A FEW MONTHS BACK. THIS CAR IS EQUIPPED WITH A FEATURE, THE DE-ACTIVATION OF THE FRONT SEAT PASSENGER AIRBAG WHEN THE SEAT IS VACANT. MY WIFE WEIGHS ABOUT 104 LBS AND DOES NOT ALWAYS ACTIVATE THE SWITCH AS INDICATED BY THE FACT THE WARNING LIGHT DOES NOT GO OFF, AND THEREFORE IS UNPROTECTED IF THERE WAS A FRONTAL CRASH. THE DEALER CHECKED AND INDICATED THAT THE SWITCH IS FUNCTIONING AS DESIGNED. THIS PROBLEM OCCURS ABOUT 50% OF THE TIME. SOMETIMES SHE CAN GET THE INDICATOR TO GO OFF BY MOVING AROUND AND/OR BOUNCING ON THE SEAT. THE OTHER FUN FACT IS THAT WE CAN BE RIDING ALONG AND THE INDICATOR WILL COME ON OR IF IT IS ON IT WILL SOMETIME TURN OFF. THERE DOES NOT APPEAR TO BE ANY RHYME OR REASON FOR THE ACTIVATION OR DE-ACTIVATION OF THE SENSOR SWITCH. I WAS TOLD BY THE DEALER THAT THE SENSOR SWITCH CAN NOT BE BY-PASSED BECAUSE OF FEDERAL REGULATIONS. *NM

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.

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.

PE10046 · Transmission Shift Cable Detachment

Opened Nov 22, 2010 · Closed Apr 5, 2011

Status: closed (inferred from source dates) · Power Train:automatic Transmission; Power Train:automatic Transmission:gear Position Indication (prndl); Power Train:automatic Transmission:lever And Linkage:floor Shift

During manufacture the automatic transmission shift cables in certain subject vehicles were installed incorrectly causing extra tension on the cable.This condition can cause the shift cable to detach from the gear shifter assembly's dowel pin preventing the transmission from being shifted.The shift lever can be moved into the Park (P) position while the vehicle transmission is still in the last used gear before detachment.If this were to occur, and if the driver leaves the vehicle without engaging the parking brake, the vehicle may inadvertently roll away thus creating the risk of a crash.Kia is conducting a safety recall (11V-153) to correct the subject problem in approximately 70,115 model year (MY) 2006 through 2008 Kia Optima vehicles produced from 9/29/2005 to 6/13/2007.Kia has stated that the early MY 2006 Optima vehicles built before 9/29/2005 had different automatic transmission shift cables and shift levers than the subsequent MY 2006 through early MY 2008 Optima vehicles built up to 6/13/2007.Beginning 6/14/2007, Kia changed the assembly process for the shift cables to ensure correct installation.As for the recall remedy, Kia dealers will inspect the shift cables for correct installation, and re-install them, if necessary.For more details on the recall, see NHTSA recall 11V-153.This investigation is closed.
