The passenger restraint system in my vehicle has suffered a critical safety failure, and the manufacturer (Hyundai Motor America) is refusing to remedy the defect, leaving the front passenger airbag completely disabled. The Supplemental Restraint System (SRS) airbag warning light is permanently illuminated on the dashboard, accompanied by the "Passenger Airbag Off" indicator, even when an adult is seated in the front passenger seat. A diagnostic scan performed by an authorized Hyundai dealership confirmed a catastrophic failure of the Occupant Classification System (OCS) sensor mat located inside the front passenger seat cushion. The specific Diagnostic Trouble Code (DTC) retrieved was B1490 (OCS Sensor Mat Defect). The dealership confirmed that due to this hardware failure, the front passenger airbag is completely deactivated and will not deploy in the event of a collision, posing an immediate, severe injury risk to front-seat occupants. Hyundai previously recognized widespread safety defects with this exact component and issued an 18-Year OCS Sensor Warranty Extension (Campaign Z01) to replace the front passenger seat cushion/OCS sensor free of charge. However, Hyundai Corporate and the local dealership are refusing to honor the warranty extension on my vehicle based strictly on a technicality. They state that Campaign Z01 only covers the physical replacement of the OCS sensor if the computer outputs code B1764, whereas my vehicle is outputting code B1490. Both trouble codes identify an internal, unprovoked hardware failure of the exact same OCS sensor mat assembly, resulting in the exact same hazardous condition: a permanently disabled passenger airbag. By denying coverage based on a software code variation for an identical component failure, Hyundai is failing to remedy a known restraint system defect. I am filing this complaint to document this critical safety hazard.

Defect investigations
3.3L Engine Loss of Motive Power (LOMP)
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 Hyundaiâs 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

AQ23002
Loss of Motive Power
the federal safety agency 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 under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitionersâ 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. ODIâs evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to the federal safety agency 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. Â 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 the federal safety agency's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, the federal safety agency does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing the federal safety agencyâs reasons for denial of the petition will be published. The reference numbers for the complaints to the federal safety agency 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

What 2017 Hyundai Santa Fe owners say
Most recent owner complaints, unedited.
I am submitting a complaint regarding engine oil consumption in my 2017 Hyundai Santa Fe Sport 2.4L 4-cylinder with approximately 117,000 miles. The vehicle consumes approximately one quart of engine oil every 5,000 miles during normal operation. There are no visible oil leaks or noticeable exhaust smoke. I am concerned that the engine may be consuming oil internally due to a possible defect involving the piston rings, valve seals, or another internal engine component. The exact cause has not been professionally diagnosed. Excessive oil consumption creates a safety concern because low engine oil levels can lead to inadequate lubrication, sudden engine failure, or loss of engine power while driving, potentially putting the driver and other motorists at risk. The condition has not yet been formally confirmed by a dealership or independent repair facility. The vehicle has not undergone a formal manufacturer or third-party inspection specifically for this issue. The engine is available for inspection upon request. There are currently no check-engine warning lights or diagnostic trouble codes. No visible smoke or external oil leaks have been observed. The primary symptom is the gradual loss of engine oil during normal driving. I am requesting that the federal safety agency document and investigate this condition to determine whether it may be related to an engine defect affecting Hyundai vehicles equipped with the 2.4L engine.
On October 14, the vehicle experienced a sudden and catastrophic loss of motive power ("limp mode") while driving at highway speeds, creating an immediate and severe risk of a high-speed rear-end collision. Notably, no Check Engine Light or dashboard warning illuminated prior to or during this sudden deceleration to warn of the failure. On October 16, the vehicle was transferred to an authorized manufacturer dealership (ABC Hyundai in Las Vegas, Dealer Code NV031), where it is currently located and available for inspection. The vehicle has now been in the dealership's custody for 17 consecutive days. Despite telematics data proving the vehicle is being actively started and driven around the dealership lot across multiple shifts, the service department has refused to formally document the diagnostic trouble codes (DTCs) or submit the mandatory engine failure diagnostic paperwork to the manufacturer. The manufacturer's corporate customer care department confirmed on day 17 that the dealership has submitted zero diagnostic data to them regarding this failure. Furthermore, the vehicle had three open safety recalls when surrendered. Records indicate the dealership has performed two of these recall repairs during this 17-day hold without providing any notification, status updates, or documentation to me. Yet, they have deliberately left the most critical mandate—an "URGENT: FIRE RISK WHEN PARKED" safety recall (the federal safety agency Recall 22V056000)—unrepaired. The dealership is actively holding, starting, and driving the vehicle without mitigating this urgent fire risk, while simultaneously refusing to process the engine failure diagnostics or provide a safe alternative vehicle. The dealer's deliberate refusal to process the catastrophic engine failure while selectively performing other recall work in secret presents an ongoing safety hazard and a gross lack of transparency.
The engine light came on. Upon driving it on the highway it would lost acceleration but was able to drive under 50 miles per hour about 5 miles. When opened the hood there was fluid splattered on the engine. There is a hole in the upper left quadrant beneath the engine cover.
Odometer Fraud. The contact purchased a 2017 Hyundai Santa Fe. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of the purchase, the mileage was 45,000. However, when the vehicle was taken to a dealer for a trade-in, it was discovered via a Carfax report that the mileage was over 109,000.
On [XXX], Laguna Niguel Hyundai performed Service Campaign 9C2 (ECU software update for Theta II emissions improvement, Hyundai TSB 26-01-013H) on my 2017 Hyundai Santa Fe Sport. Immediately after the update, the vehicle developed drivability problems that did not exist before: rough/harsh shifting, hesitation, and loss of power during cold-start operation (the first 1-3 minutes after engine start), plus intermittent infotainment and navigation system failures. Hyundai's own dealer notice dated 05/18/2026 acknowledges vehicles may exhibit 'hesitation or rough shifting' after the 9C2 update and states the matter is 'currently under review' — no permanent fix has been released. The dealership that performed the recall has since refused to service my vehicle again. I opened case #[XXX] with Hyundai corporate; my inquiries on 09/03/2026, 09/11/2026, and 09/17/2026 asking for a corrective action have gone unanswered. The hesitation and power loss are a safety hazard when merging into traffic or crossing intersections. I request the federal safety agency investigate this pattern.

Was driving down road car went into limp mode about caused a big wreck, check engine was flashing and heard a loud noise as I was trying to get to safety. Had the car scanned and was for code p1326 and looking at all the recalls nothing is for the 2.4l but y'all have been having a lot of issues with these theta 2 engines.
Immediately following the mandatory Hyundai Servie Campaign Update 9C2-ECU THETA 11my vehicle began exhibiting severe hesitation, very rough idling, jerking at slow speeds and when gear changes, difficulty going up inclines and almost feel at times as though it is about to lose power which poses life threatening situations especially when turning into traffic. I have reported it to the dealers who never once test drove the vehicle but said to me that they did and could find no problem, however they did make me pay for repairs which never fixed the problem. I returned three times with the same issue. They recommended a Fuel Induction Service and a Auto Trans Service. Spark plug change. Igniton coils change. Nothing worked!
Component/System Failed: Engine assembly (Theta II 2.4L GDI) and Exhaust/Catalytic Converter. Description: The vehicle suffered a failure associated with the known Theta II engine defects. Engine oil consumption and internal engine wear directly led to unburned fuel and debris entering the exhaust stream, resulting in severe catalytic converter restriction/failure. Safety Risk: The combined failure caused sudden loss of power while driving, engine stalling, and significant driveability hazards, creating an immediate risk of a rear-end collision on public roads. Confirmation & Inspection: The failure was confirmed and diagnosed by a certified service facility. Replaced components and diagnostic documentation remain available for inspection upon request.
