PURCHASED NEW A 2010 HYUNDAI SANTA FE, SE. THE PROBLEM THAT OCCURS RANDOMLY EVERY FEW DAYS IS WHEN ACCELERATING SLOWLY AT AROUND 20-30 MPH AND THE TRANSMISSION SLIPS OUT OF 2ND GEAR EFFECTIVELY PUTTING THE TRANSMISSION IN NEUTRAL FOR ABOUT 1 SECOND, AND THEN WILL HARD SHIFT INTO 3RD GEAR MAKING A LOUD BANG NOISE. IT CAN FEEL AS THOUGH I WAS REAR ENDED. THIS PROBLEM HAS BEEN OCCURRING SINCE NEW AND HAS BEEN TAKEN TO THE DEALER MULTIPLE TIMES WHERE THERE THE PROBLEM COULD NOT BE REPLICATED. THIS IS THE SAME COMPLAINT AS WITH ABOUT 10% OF THE 140 OR SO COMPLAINTS ON THE NHTSA SITE FOR THIS YEAR AND MODEL. THERE ARE AT LEAST 2 AND POSSIBLY MORE TSB'S THAT APPEAR TO ADDRESS THIS PROBLEM (TSB-10-AT-006, 12-AT-012, 12-AT-009-2). I WILL ATTEMPT TO ADDRESS THE PROBLEM AGAIN WITH THE DEALER ASKING HIM TO REVIEW THESE SPECIFIC TSB'S. AFTER SO MANY COMPLAINTS ABOUT A VERY SPECIFIC PROBLEM TO A VITAL DRIVETRAIN COMPONENT, IT IS TIME FOR HYUNDAI TO TAKE OWNERSHIP OF THIS PROBLEM AND FIX IT! THE CONSUMER SHOULD NOT HAVE TO GO THROUGH SO MUCH HASSLE FOR A WIDELY KNOWN ISSUE. HOW MANY MORE PEOPLE HAVE THIS PROBLEM AND DON'T TAKE THE TIME TO REPORT IT?

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

Official recalls
2Apr 1, 2013
Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. 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: Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.
Apr 28, 2011
HYUNDAI IS RECALLING CERTAIN MODEL YEAR 2010 SANTA FE 2WD VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSIONS AND 2.4L ENGINES MANUFACTURED FROM OCTOBER 15, 2009 THROUGH MARCH 5, 2010. THE INTERMEDIATE SHAFT MAY SUFFER FROM NOISE AND EXCESSIVE WEAR DUE TO A MISALIGNMENT OF THE INTERMEDIATE SHAFT WITH THE RIGHT SIDE OUTPUT GEAR. CONTINUING TO DRIVE THE VEHICLE IN THIS CONDITION LEADS TO THE DEVELOPMENT OF A WHIRRING/WHINING NOISE AND CAN EVENTUALLY CAUSE DAMAGE TO THE AUTOMATIC TRANSMISSION.
Consequence & remedy
Consequence: DAMAGE TO THE TRANSMISSION MAY CAUSE LOSS OF MOTIVE POWER, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE RIGHT SIDE OUTPUT GEAR AND INTERMEDIATE SHAFT FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING JUNE 2011. OWNERS MAY CONTACT HYUNDAI'S CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151.

3DP22003 · 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.
