2016 Hyundai Santa Fe Sport

The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651. Kia recalls 16V-815, 20V-518, 20V-519, 21V-137, 21V-331, 22V-051, 22V-800, and 23V-652 The purpose of this AQ is to evaluate the timeliness and scoping of Hyundai and Kia’s defect decision making and adherence with reporting requirements; and understand the varying defect descriptions and remedies between these recalls.

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.

my BSD sensor would go on and off for the last several months when no one was around me. I work early and even when I was alone on the road the BSD would flash for 2-3 mins and go off.. then my fan for my air conditioner stopped. When I removed the glove compartment to see the wire connecting to the fan is "melted". When i called bob king hyundai, I was informed there was no recall. So, I attempted to fix the issue myself only to find the fuses (under the hood) are almost all bad. The tips of the fuses will not pull out. only the body of the fuse. With all this happening over the last several days and by the way, the vehicle passed inspection. I wanted to reach out as this is definitely a fire hazard and a huge concern.

The engine (2016 Hyundai Santa Fe 2.0L/2.4L Theta II GDI engine) suffered a catastrophic internal mechanical failure, specifically related to the known connecting rod bearing defect. The vehicle is currently un-driveable and is located at Serra Hyundai in Trussville, AL. The vehicle and its failed engine are available for inspection upon request. The engine suddenly failed and lost all power while driving at highway speeds in active traffic. I was forced to coast a dead vehicle across multiple lanes of traffic to the shoulder without any acceleration capability. Yes. The vehicle experienced a complete failure, cannot be restarted, and is currently parked at an authorized Hyundai dealership The vehicle is currently at an authorized Hyundai dealership awaiting a formal corporate inspection and evaluation for engine replacement approval. It has not been inspected by police or insurance. There were no long-term warning lamps, messages, or symptoms prior to the incident. The vehicle was operating normally until the exact moment of the failure, when the engine suddenly began knocking loudly, lost power, and stalled within seconds.

Incident

May 13, 2026

The vehicle is a 2016 Hyundai Santa Fe Sport. It had previously been included in an engine-fire-related recall/service campaign, and Hyundai replaced the engine between approximately October 2024 and January 2025 at about 113,000 miles. About 10,000 miles and 14 months later, the vehicle developed engine/performance problems. A Hyundai dealership service center performed about $6,500 in repairs, including installation of a new transmission, and represented that the engine and transmission had a lifetime guarantee. One day after the vehicle was returned from the dealership, the engine compartment caught fire while the vehicle was being driven. The fire rapidly escalated, the vehicle exploded/burned, and the vehicle was destroyed down to the frame. The occupants escaped, but the incident created an immediate risk of serious injury or death. The failed component appears to involve the engine, engine compartment, fuel/oil/electrical systems, transmission-related repair area, or another drivetrain component. The vehicle remains may be available for inspection depending on insurance/tow/storage status. The vehicle had recently been repaired and inspected by a Hyundai dealership service center. This incident raises concern that the recall-related engine-fire risk, replacement engine, recent dealership repairs, transmission installation, or related components may have failed and created a serious fire hazard.

The engine powertrain system, specifically the internal engine lubrication, timing chain, and camshaft sensors. The vehicle's Theta II engine suffers from systemic, excessive oil consumption, which starved the engine of lubrication. This caused the timing chain to stretch and mechanically fail, and compromised the camshaft sensors. The vehicle is currently un-repaired and is available for inspection upon request at Hyundai of Downtown LA. While driving, the engine suddenly stalled and completely shut off mid-drive without warning. This caused an immediate loss of motive power and a dangerous reduction in steering and braking control while surrounded by active traffic. Operating a vehicle that randomly shuts down on public roads presents an extreme, life-threatening safety hazard to myself, my passengers, and other drivers. Furthermore, the dealership is attempting to force me to drive the vehicle for an additional 1,000 miles in this stalling, un-repaired condition to complete a corporate oil test, compounding the safety risk. The failure and safety hazard have been physically confirmed and diagnosed by an authorized dealership: Hyundai of Downtown LA (3850 S Figueroa St, Los Angeles, CA 90037). Their service department mechanically diagnosed the physical failure of the camshaft sensors, a stretched timing chain, and severe engine oil starvation. There were absolutely no dashboard warning lights, check engine lights, low oil pressure lamps, or messages prior to the engine stalling and shutting off. The vehicle computer failed to trigger any diagnostic trouble codes (DTCs) or dashboard warnings to alert me to the low oil level or the impending mechanical timing failure before the vehicle completely shut down mid-drive.

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.

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.

In response to this trend, we engineered a software upgrade that addresses the social media theft method and made it available to owners of eligible models free of charge at authorized Hyundai dealers since early 2023. In addition to the anti-theft software, we’ve developed a new zinc-reinforced ignition cylinder protector hardware upgrade that can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because your Hyundai vehicle with the VIN listed above (“Subject Vehicle”) was not factory-equipped with an engine immobilizer and was previously eligible for the software upgrade, you are now eligible until March 31, 2027 to have the ignition cylinder protector installed — if you request it — at no cost to you through an authorized Hyundai dealership.
