WHEN THE VEHICLE SLOWS TO 20 MILES PER HOUR, THE CAR DOWNSHIFTS HARD BY ITSELF. IN RESEARCHING ONLINE, I FOUND NUMEROUS REPORTS OF THE SAME THING. IN SPEAKING WITH MY PERSONAL MECHANIC, HE SAID THIS SHOULD BE COVERED UNDER THE TRANSMISSION PORTION OF THE POWER TRAIN WARRANTY - NEW TRANSMISSION SOFTWARE NEEDS TO BE RE-DOWNLOADED TO THE CAR'S COMPUTER AND THEN THE COMPUTER RESET - THIS SHOULD RETRAIN THE TRANSMISSION ON WHEN TO DOWNSHIFT. *TR

AFTER A BATTERY REPLACEMENT, THE BATTERY SPARKED WHEN THE CAR FIRST TURNED ON, BUT THE CAR IMMEDIATELY TURNED ON. FROM THAT POINT FORWARD WE HAD THE CHECK ENGINE LIGHT ON, THE BRAKE LIGHT ON AND TWO OTHER LIGHTS ON THE DASH ON CONSTANTLY. WE TOOK IT IN AND SPENT $4000+ ON OIL CHANGES, FRONT END REPLACEMENT AND SEVERAL OTHER ITEMS THAT TOOK ALMOST A MONTH AND A MASTER MECHANIC FROM KIA TO FIND OUT THAT THE PROBLEM WAS A WIRING HARNESS ISSUE. WE WERE TOLD THAT WE HAD BEEN IN AN ACCIDENT AND THAT BECAUSE OF THAT IT WASN'T GOING TO GET REPLACED UNDER WARRANTY. THE CAR WAS NEVER IN AN ACCIDENT, AND THE WIRING HARNESS STILL SHOWS FOUR LIGHTS ON THE DASH. IF A SIMPLE BATTERY REPLACEMENT CAN CAUSE THE WIRING HARNESS TO FRY THERE MUST BE A PROBLEM, AND I DON'T THINK IT'S THE BATTERY. *TR

I PURCHASED A USED KIA OPTIMA IN MARCH 2012, BUT HAD, WHAT I THOUGHT WERE "GRABBING" BRAKES. I TOOK IT IN WHEN I FOUND A SERVICE BULLETIN TSB-067. I HAD THE CAR ANALYZED, AND FOUND IT HAD THIS SHIFTING ISSUE. I HAD THE REPROGRAMMING DONE AND EVERYTHING WAS FINE FOR A LITTLE OVER A YEAR, THEN NOT ONLY DID THE DOWNSHIFTING ISSUE START BACK UP AGAIN, BUT NOW HAVE ACCELERATION ISSUES AS WELL. NOW THE VEHICLE "LOPES" ON ACCELERATION - SOMETIMES A LOT . I CONTACTED KIA ABOUT IT, AND THEY SAID I HAD TO TAKE IT BACK FOR DIAGNOSIS YET AGAIN, AND THEN THEY WOULD THINK ABOUT REIMBURSEMENT FOR THE SECOND SERVICE APPOINTMENT. I DO NOT UNDERSTAND WHY THERE IS NOT A RECALL ON IT YET. IT IS DESTROYING MY TRANSMISSION BECAUSE OF THE "BANGING" OF THE TRANSMISSION DUE TO THE EXTREME DOWNSHIFTING OF THE VEHICLE. *TR

Official recalls
1Apr 1, 2013
Kia Motors Corporation (Kia) is recalling certain model year 2007-2010 Rondo, model year 2007-2011 Sedona, Sorento and Sportage, model year 2010-2011 Soul, model year 2008-2011 Optima, model year 2010 Forte, model year 2007-2009 Amanti, and model year 2009 Borrego vehicles. Originally, in April 2013, Kia recalled 623,658 model year 2007-2010 Rondo and Sportage, model year 2007-2011 Sorento, model year 2007 Sedona, model year 2010-2011 Soul, and model year 2011 Optima vehicles. In September 2013, Kia informed the agency that it was adding an additional 356,719 vehicles to this campaign. The total number of vehicles being recalled is now 980,377. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake-transmission shift interlock feature preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Consequence & remedy
Consequence: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of PARK without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Remedy: Kia will send an interim notification to owners in May 2013. When parts are available, owners will receive a second notification and dealers will replace the stop lamp switch, free of charge. Owners may contact Kia at 1-800-333-4542. Kia's recall campaign number is SC098.

2DP22003 · 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.
