2010 Hyundai Santa Fe

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.

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.

On April 25, 2011, Kia Motors Corporation submitted a defect notification letter to NHTSA regarding a transmission intermediate driveshaft condition in approximately 12,690 model year (MY) 2011 Kia Sorento 2-wheel drive vehicles equipped with automatic transmissions and 2.4L engines (NHTSA Recall No. 11V-258).The recall addresses a defect with the external shape of the engine block which can prevent the intermediate shaft bearing bracket from mating evenly with the engine block.This can cause a misalignment of the intermediate shaft with the right side output gear.Resulting damage could cause a loss of motive power.Additionally, on April 27, 2011, Hyundai Motor Company submitted a defect notification (NHTSA Recall No. 11V-261) for the same issue in approximately 6,169 MY 2010 Sante Fe 2-wheel drive vehicles equipped with automatic transmissions and 2.4L engines that use the same components as the recalled Kia Sorento vehicles.This investigation is closed.

On XXX I was waiting at a light and the check engine light was blinking. When I started up, the car was very sluggish. It continued to be sluggish on my trip home - 5 miles. I brought it to Meineke [XXX] [XXX]. They ascertained that the engine was shot. They flushed out the oil in the engine and there was lots of metal in the oil. They instructed me to go to Hyundai immediately. There was a engine recall and their research showed that I was included under the recall warrenty. I've included their assessment. Both the drives to the Meineke from my house and to Hyundai from Meineke were scary. I didn't feel safe in the car. I went directly to [XXX], manager of Larry Miller Hyundai at [XXX], Phone [XXX]. He said that he needed to clear the recall with Hyundai. He called me back in a few days and told me that all the test diagnostics were made and that a censor malfunction was the cause of the problem and the front breaks needed work. I gave him the go-head. The cost was $1,319. I wasn't convince that was the primary problem. I use my car for short trips. I was driving to the gym on XXX - having driven less than 50 mile since the recent repair - once again I stopped at a light and the check engine light lit up permanently - not flashing. The engine started to shake when it was idle and there was an unusual sound coming from it. I finished my drive to the gym although the drive just didn't feel normal or safe. Right now (XXX) I am having my car towed to Hyundai. It is not safe to drive. My belief is that corporate Hyundai refused to fix the engine repair part of a class action lawsuit which includes replacing the engine. They had to see that my recall warrenty ends in September and they figured they'd stall until the warrenty was no longer valid. This is just a guess, but a very educated guess. They had to know that the engine was no longer safe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2010 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the vehicle stalled. No warning lights were illuminated. The vehicle failed to immediately start, but started after several attempts. The vehicle was taken to an independent mechanic, who replaced the starter, oil filter, and engine filter, and changed the oil. On a hot day, there was a loud sound coming from the vehicle, and it was noticed that the unoccupied vehicle was attempting to start independently. The contact unlocked the vehicle and opened the vehicle door, put the keys in the ignition, and continued to crank for approximately four minutes. The accelerator pedal was pumped, and the vehicle stopped. There was smoke coming from the vehicle, and the vehicle eventually stopped. There were flames coming from the vehicle. The contact called 911, an independent mechanic, her father, and the fire department. The Fire Department was able to extinguish the fire and disconnect the battery. The mechanic determined that the engine cover was burned. There were no reported injuries. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The contact indicated that the failure was related to NHTSA Campaign Number: 11E040000 (Equipment). The insurance company referred the contact to the NHTSA Hotline for assistance. The manufacturer was not contacted. The failure mileage was approximately 145,000.

I hadn't used the car in a few weeks (rarely leave the house because I work from home). I went to visit a friend on December 26th or 27th (don't remember exact date). On the way there the engine started having a knocking noise. On the way home after eating a meal with the friend, the knocking got louder, and the car was losing power. As I drove up a hill, the engine was providing almost no power, and then I heard a very loud bang, and a blue-ish, white smoke cloud came out from under the car, and it died completely. As a secondary issue, since this was right after Christmas, I couldn't find an open shop to have it towed to, so it was left on the side of the road overnight. The next day when I drove back to meet a tow-truck driver at the car, we found it had been broken into overnight, and my wife's childhood Christmas decorations were stolen. Nothing else of value was taken. I did have police come out and make a report at the time. I only just discovered that the engine was under a recall for "Campaign 966" for this exact issue.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

This TSB references the Op codes to use for claim submission and the Parts required based on the vehicle’s inspection results from TSB 22-01-023H-2 (DTC P1326 – Engine Bearing Inspection/Engine Replacement) or the latest version.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.

Hyundai is conducting a campaign to enhance the knock sensor software to detect abnormal engine bearing noise before potentially severe engine damage occurs. If abnormal engine bearing noise is detected, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Engine Protection Mode allowing the customer to drive to the nearest Hyundai dealer for diagnosis and repair. In addition, DTC P132600 will be recorded in the ECM. The vehicle can continue to be operated for a limited time in Engine Protection Mode, but it will accelerate slower and have a reduced maximum speed. Engine RPMs will be limited to approximately 1800-2000 RPM.
