I PURCHASED A USED 2017 SANTA FE AWD ON 11/06/2019. THE CAR FAILED TO START ON THE FIRST ATTEMPT AT A GAS STATION -- THE FIRST TIME IT HAS HAPPENED AFTER PURCHASING THE CAR. IT STARTED ON THE SECOND ATTEMPT, THE CAR DROVE SMOOTHLY TO THE DMV FOR REGISTRATION. ABOUT 1-2 HOURS OF DRIVING, THE CAR STALLED IN TOWN DESPITE ACCELERATING WITH RPMS GREATER 3. THE CAR BECAME RESPONSIVE ONLY AFTER STOPPING AND RESTARTING AT THE CURB. I NOTICED A STEADY CHECK ENGINE LIGHT ON THE DASHBOARD FOR THE FIRST TIME AFTER THE INCIDENT AND HAVE BEEN HAVING A JERKY RIDE EXPERIENCE EVER SINCE. A CALL TO BLUELINK CONFIRMED THAT THE CAR REQUIRES A THOROUGH SYSTEM CHECK INVOLVING THE POWER TRAIN AT THE DEALERSHIP. AN APPOINTMENT HAS BEEN FOR 12/4/2019 AND THE CAR HAS BEEN PARKED.

3DP24001 · 3.3L Engine Loss Of Motive Power (lomp)
Opened Feb 8, 2024 · Closed May 16, 2024
Status: closed (inferred from source dates) · Engine
The Office of Defects Investigation (ODI) received a petition on February 2, 2024, requesting a defect investigation into an alleged defect of the "engine" on the following vehicle model: 2017 Hyundai Santa Fe vehicles equipped with the 3.3L V-Shaped GDI Lambda-II engines. The petition cites allegations of a loss of motive power, often resulting in an engine seizure. The stall is preceded by a knocking sound, decreased performance and no warning lights. An analysis of the subject vehicle population was undertaken using complaints submitted to ODI along with manufacturer data. It was determined that the frequency of events is low for the subject population, while those that specifically report a loss of motive power event have a high mileage at the time of incident. The 2017 Santa Fe is equipped with a service interval reminder for the consumer that must be set by the consumer themselves or at a dealership. A Technical Service Bulletin (19-EM-002H) instructs the dealership to set the maintenance reminder at the completion of routine maintenance service or anytime a repair is performed that requires new engine oil. This maintenance reminder will help reinforce the need for proper oil maintenance intervals. Additionally, the Santa Fe vehicles with 3.3L V-shaped Lambda-II engines will be added to Hyundai’s existing Technical Service Bulletin (23-EM-007H) related to combustion chamber cleaning. These actions will help limit negative consumer incidents related to loss of motive power. Lastly, Hyundai has extended the limited engine warranty for MY 2013-2019 Santa Fe vehicles equipped with 3.3L V-shaped Lambda-II engines included in the Petition. The updated coverage is 15 years, or 150,000 miles and details are contained in Technical Service Bulletin 24-EM-003H. In view of the service interval reminder, combustion chamber cleaning, and extended warranty actions being taken by Hyundai, ODI is denying this Defect Petition. The agency reserves the right to take additional action if warranted by future circumstances. To review the report cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

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.
