I HAVE BEEN RESEARCHING THE PROBLEM I HAVE WITH MY 2005 KIA OPTIMA AND I FOUND OUT THAT I AM NOT THE ONLY PERSON WITH THIS ISSUE. THEREFORE I SAW IT NECESSARY FOR ME TO BRING THIS TO YOUR ATTENTION. THE DOOR LATCHES ARE MALFUNCTIONING. THIS IS A MAJOR SAFETY HAZARD BECAUSE IF THE CAR EVER CAUGHT FIRE OR IF THE CAR EVER WENT INTO A RIVER, GOT FLOODED, OR IN A WRECK IT WOULD BE VERY DIFFICULT FOR THE DRIVER TO GET OUT OF THE CAR. MY DRIVER SIDE DOOR WILL NOT OPEN, FROM THE INSIDE OR THE OUTSIDE. IT STAYS LOCKED AND EVEN WHEN YOU UNLOCK THE CAR, THE DOOR WILL NOT OPEN. I CURRENTLY HAD A BABY AND HAD TO HAVE A C-SECTION. IT WAS HORRIBLE HAVING TO CLIMB IN AND OUT THE CAR THROUGH THE PASSENGER SIDE.... FROM RESEARCHING THIS ISSUE I HAVE COME ACROSS SO MANY PEOPLE THAT HAVE HAD THE SAME ISSUE. KIA SHOULD RECALL THE 2005 OPTIMA. *TR

I WENT TO KIA DEALERSHIP REGARDING KEYLESS REMOTE NOT WORKING. I ADVISED DEALERSHIP THAT BOTH REMOTES WERE RE-PROGRAMMED 12 MONTHS AGO AND THAT ONE REMOTE STOPPED WORKING 6 MONTHS AFTER RE-PROGRAMMING AND THE 2ND REMOTE STOPPED WORKING 12 MONTHS AFTER RE-PROGRAMMING. BASED ON DISCUSSION, IT APPEARS THAT 2003 THROUGH 2006 KIA OPTIMAS HAVE DEFECTIVE KEYLESS REMOTE SYSTEMS, BUT BECAUSE THERE HAS BEEN NO FORMAL RECALL, REPAIR OF KEYLESS REMOTE IS NOT COVERED OUTSIDE OF WARRANTY. I BELIEVE REPAIR COST IS ABOUT $400. MY OPINION IS THAT A RELATIVE KEYLESS REMOTE RECALL SHOULD BE MADE BY KIA SINCE THE KEYLESS REMOTE DEFECT IS NOT CUSTOMER'S FAULT. *TR

SWITCHED AGAIN, MAY COME 'ON', TURNED 'OFF' THEN 'ON' MAY OR MAY NOT COME ON). DEALER STATES 'IT HAPPENS, THEY BURN OUT', YET SAID THE BATTERY NEEDED TO BE REPLACED.(?) NON WARRANTY, SO YOU PAY. ANOTHER COMPLAINT ON THE SAME CAR YEAR/MAKE/MODEL, SAME ISSUE, HAS ALREADY BEEN FILED WITH YOU. IN ADDITION, 'GOOGLE' SEARCH SHOWS MANY ENTRIES FOR THIS SAME PROBLEM ON KIA AND HYUNDAI VEHICLES (SAME MANUFACTURER) OVER MANY MODELS/YEARS. SIGNS POINT TO POSSIBLE DEFECTIVE CHARGING OF BATTERY BY VEHICLE'S ELECTRICAL SYSTEM (MAYBE WHY THEY REPLACED THE BATTERY AT THE SAME TIME). BATTERY WAS PREVIOUSLY FINE. I'VE HAD MANY ELECTRICAL PROBLEMS WITH THE CAR, THINGS STOP WORKING, THEN WORK ON THEIR OWN (POWER WINDOW WON'T WORK, STICKS PART OPEN. SWITCH DOES NOTHING. THEN SUDDENLY LATER WINDOW LOWERS/RAISES WITHOUT SWITCH BEING TOUCHED. TRUNK SUDDENLY POPS OPEN). DEFINITE ELECTRICAL PROBLEM ON THESE MAKE OF VEHICLES OVER MANY YEARS WHICH NEITHER MANUFACTURER IS GOING TO ADDRESS THEMSELVES. UNLESS YOU DO SOMETHING, MANY WILL BE PAYING FOR SERVICE CAUSED BY THEIR NEGLIGENCE. . ALSO, SEAT BELT DOES NOT RETRACT ALL THE TIME. MY VEHICLE WAS PURCHASED NEW. *TR

THE FIRST TIME THAT IT BROKE DOWN WAS A WEEK AFTER WE BOUGHT IT AND THE MECHANICS TOLD ME THAT THERE WAS NOTHING WRONG WITH THE CAR. THE DRIVERS SIDE DOOR WILL NOT UNLOCK, AND WHEN I HAD THE THROTTLE REPLACED THE MECHANICS AT THE DEALERSHIP DID NOT EVEN DO THE REPAIR CORRECTLY CAUSING THE CAR TO REV UP WHEN STOPPED.

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.
