MY KIA OPTIMA BEGAN CONSUMING LARGE AMOUNTS OF OIL BUT IT WASN'T LEAKING OUT OR BURNING OFF ANYWHERE. I BEGAN TO WATCH THE OIL LEVELS CLOSELY AND WAS DOWN 2 QTS EVERY WEEK. AT SOME POINT THE OIL PRESSURE GOT TOO LOW AND WE THINK SUCKED AIR INTO THE ENGINE. THE CHECK ENGINE LIGHT CAME ON AND THEN OFF AGAIN AS IT HAS BEEN FOR THE PPAST YR BUT FOR AN EVAP PROBLEM - A VERY SMALL LEAK KEPT GETTING DETECTED. I SPENT $1800 AT FIRESTONE THE PREVIOUS UR THE COLDER KEPT COMING BACK ON AND OFF. BUT THIS DIDN'T EXPLAIN THE SIDDEN MASSIVE OIL CONSUMPTION. SUDDENLY ON OCT. 21 MY CAR SUDDENLY IDLED VERY HIGH WITHOUT MOVING AND THE THE CHECK LIGHT CAME ON AGAIN AND STAYED ON. THE ENGINE BEGAN TO KNOCK LOUDLY ESPECIALLY WHEN ACCELLERATING OR CLIMBING HILLS. MY MECHANIC FRIEND TOLD ME ONE OF THE ENGINE RODS WAS DAMAGED AND THE COMPUTER CODE CHECK VERIFIED THAT THE CRANKSHAFT TIMING OIL CONTROL VALVE WAS NOT WORKING PROPERLY. THIS WOULD EXPLAIN THE LOW OIL PRESSURE AND DAMAGE TO THE ENGINE. I WAS ABLE TO FIND THE PROBLEM ON KIA'S WEBSITE WITH MANY COMPLAINTS REGARDING THE SAME ISSUE. KIA HAD A RECALL REGARDING THIS PROBLEM FOR MANY OF THEIR CARS BUT OF COURSE NOT MINE. I WAS VERY UPSET OVER IT. I HAD GOTTEN THE CAR ONLY 3 YEARS PRIOR AND IT ONLY HAD 150K MILES ON IT. I TOOK REALLY GOOD CARE OF IT. KIA SAID THEY COULD DO NOTHING. MY ONLY OPTION WAS TO JUNK THE CAR AND HAVE TO BUY A NEW WHEN I WASN'T IN A POSITION TO DO SO. KIA HAS DISAPPOINTED ME GREATLY. BECAUSE OF THIS PROBLEM I MAY NEVER BUT ANOTHER KIA. I WAS SO EXCITED ABOUT GETTING MY KIA AS IT HAD ALL THE FEATURES I WANTED IN A CAR AND AT A VERY GOOD PRICE BUT IT IIS ONLY GOOD IF IT RUNS. THIS PROBLEM SHOULD HAVE BEEN INCLUDED IN THW RECALL FOR MY CAR AS IT IS A HUGE PROBLEM AS I READ COMPLAINT AFTER COMPLAINT ONLINE FROM OTHER KIA OPTIMA OWNERS.

MY HUSBAND AND I USED A PREMIUM OIL FILTER (NOT KIA), AND A FEW WEEKS LATER HAD A KNOCKING IN THE ENGINE. I TOOK THE CAR TO A SHOP UP THE STREET AND WAS TOLD THAT SINCE WE USED AN OIL FILTER THAT WAS NOT KIA, THE FILTER CAUSED METAL IN THE ENGINE WHICH NOW NEEDS TO BE REPLACED. I CALLED KIA CONSUMER AFFAIRS AND EXPLAINED THE ISSUE. WITH ALL THE INFORMATION THAT WAS SENT TO ME IN 6 YEARS, NOT ONE PIECE STATED THAT YOU ARE REQUIRED TO USE A KIA OIL FILTER. THE SHOP THAT I ORIGINALLY TOOK THE CAR TO HAD TO DO SOME RESEARCH AND STATED THAT THERE ARE BULLETINS OUT THAT ARE ONLY AROUND 2 YEARS OLD. WHILE SPEAKING WITH CONSUMER AFFAIRS, I WAS TOLD THAT THE CAR NEEDED TO GO TO A KIA DEALER TO BE DIAGNOSED. I THEN HAD THE CAR TOWED TO A LOCAL DEALER WHICH STATED THE SAME THING. NOW, THE KICKER, THEY WILL NOT HELP IN FIXING THE ENGINE BECAUSE I AM OVER THE 100,000 MILE MARK. ON TOP OF THAT, I AM NOW CHARGED A TOW BILL AND MORE DIAGNOSTIC FEES ON TOP OF WHAT I ALREADY PAID IN WHICH THEY WILL NOT PAY FOR EITHER (SINCE THEY REQUIRED THE CAR TO BE AT A DEALER FOR ASSISTANCE). I CALL THE CONSUMER AFFAIRS LADY THAT I HAVE BEEN WORKING WITH, AND SHE WILL NOT RETURN MY CALL UNTIL I CALL THE 800 NUMBER AND TELL THEM I NEED TO SPEAK TO SOMEONE OR I WILL BE GOING TO THE LOCAL MEDIA AS WELL AS ANY SOCIAL MEDIA AVENUE I CAN. THE DEALER THAT I PURCHASED THE CAR FROM WILL ALSO NOT HONOR THE "ENGINE FOR LIFE" THAT I SIGNED UNLESS I CAN PROVIDE ALL RECEIPTS FROM THE LAST 5 YEARS ON ANY MAINTENANCE THAT I DID ON THE CAR OUTSIDE OF A DEALER (AIR FILTER, ETC). I HAVE RECENTLY BEEN MARRIED AND THE ACCOUNT CLOSED. AND - WHO KEEPS THEIR RECEIPTS FOR 5 YEARS ON AIR FILTERS?? THIS IS NOT ONLY POOR CUSTOMER SERVICE FOR A LOYAL CONSUMER, BUT THE LACK OF FOLLOW THROUGH WITH WHAT YOU "AGREED" TO AND SIGNED UPON PURCHASE NOT BEING HONORED. *TR

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.
