2018 Hyundai Santa FE Sport

The defect

Hyundai Motor America (Hyundai) is recalling certain 2018 Santa Fe Sport vehicles. The side curtain air bags on these vehicles have a component that may detach during deployment of the inflatable curtain air bag.

The risk

If the component detaches during deployment, the curtain air bag may not inflate properly during a crash, increasing the risk of injury. Additionally, if the detached component were to enter the vehicle occupant compartment, there could be an increased risk of occupant injury.

The remedy

Hyundai will notify owners, and dealers will replace the driver and passenger side curtain air bags, free of charge. The recall is expected to begin February 9, 2018. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 171.

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 Hyundai Theta engine is a bad design that has many recalls, a history of oil consumptions, and breakdowns that leave consumers in danger, on the roadside, and out of money. This engine has a design that causes worn engine components and high oil consumption causing reduced engine power, ruined spark plugs, and engine damage with no recourse as a owner. Recently, my family member had a hesitation that causes the car to run rough and display a check engine light. She was in traffic and the vehicle was stopping. Had this been on the interstate it could have been deadly. This IS NOT UNCOMMON for these vehicles. A quick Google search is nationwide proof of an issue with these vehicles and …

The engine on this vehicle suffers from a severe oil consumption defect that was first officially reported to the authorized dealership on February 3, 2025 at approximately 90,000 miles while under the factory powertrain warranty. The vehicle completely empties its engine oil supply in under 1,000 miles of normal driving. Running entirely out of oil within such a short interval poses an imminent, extreme risk of sudden engine seizure, catastrophic mechanical failure, and sudden stalling at highway speeds. The manufacturer and dealership have physically documented this rapid depletion of oil over a 17-month period but are refusing to replace the defective components, instead attempting to …

The contact owns a 2018 Hyundai Santa Fe Sport. While the contact’s daughter was driving approximately 10 MPH, the vehicle started bucking and shaking abnormally. The warning light indicating that the oil level was low had flashed on the screen. The driver pulled over to the side of the road and waited for the contact to arrive on scene. The contact inspected the vehicle and became aware that the oil level was extremely low. The contact added oil to the engine, and the dipstick failed to indicate the oil level until there was a quart full. The vehicle was taken to a certified mechanic, who diagnosed the vehicle with engine failure and referred the contact to the dealer. While attempting to …

I had my engine replaced in Nov 2024 due to excessive oil consumption. I was required to do an emissions update due to a recall on my car. Once the dealer did the update, it caused my check engine light to come on and now I need a new catalytic converter, which was all due to the excessive oil consumption. Hyundai dealer knows this but they are telling me I’m responsible for replacing it. It should be replaced by Hyundai not me. It was the issue with the engine.
