2020 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.

Hyundai Dealership, Pedder Hyundai of Poway, applied recall 9C2 to 2020 Santa Fe on 10/20/2026. Vehicle idle is now rough at startup and gas pedal angle no longer is reliable for controlling vehicle speed. Engine surges and jerks during initial operation on residential street due to software change. The vehicle did not operate in this manner for the last six years. I never felt like I had erratic engine control due to gas pedal response. I would like this recall removed and the original software re-applied, or my car bought back by Hyundai.

My incident relates to peeling paint on my white 2020 Hyundai Santa Fe. The paint has started to bubble, crack and peel off on the rear hatch of the vehicle. Hyundai has had issues with white color paint peeling off on a variety of their vehicles, across multiple years. Hyundai issued an extended warranty program (Z05) to cover the issue. I took my Santa Fe to the Hyundai dealer body shop near me to assess my peeling paint issue. While at the body shop facility I saw and took photos of multiple white Santa Fe's and Tucson's with peeling paint that appeared to have the same paint issue my 2020 Santa Fe is starting to exhibit. Both the Hyundai dealership body shop and Hyundai's Customer Care center have stated that my specific VIN number is not covered for the issue. The Hyundai Customer Care center stated that they are unable to add me VIN number to their coverage, but advised me that if the Z05 Warranty Program for the paint defect is expanded in the future, and my VIN number becomes included, I would then be reimbursed for expenses I have incurred to address the problem. 10/20/26 - The body shop has now updated that Hyundai will cover 90% of the cost to repair the paint damage for this specific incident, but I am still pressing for them to completely cover the repair. I would also like to see my VIN number added to the Z05 Warranty Program coverage so that I, too, would receive coverage for any additional paint peeling issues should they arise during the remaining warranty period of my vehicle. I have included a picture of my Santa Fe's peeling paint issue, and a picture of one of the random cars from the Hyundai dealer body shop exhibiting the same problem.

THERE IS A RECALL FOR THE SAME ISSUE ON THIS MODEL … I HAVE A CLAIM INTO HYUNDAI TO ALLOW MY VEHICLE TO BE REPAIRED UNDER THE SAME RECALL. This is a very dangerously problem and wish it to be investigated for the 2.0 Turbo as well. X Hyundai issued two main fuel-related recalls for the 2021 Santa Fe equipped with 2.5-liter turbocharged engines due to risks of fuel leaks and fires: & • Campaign 206 (NHTSA Recall 21V308000 / May 2021): The fuel pipe connecting the high-pressure fuel pump to the fuel rail may not have been tightened to the proper torque during manufacturing. Dealers inspected and retightened the connection for free. • Campaign 207 (NHTSA Recall 21V524000 / July 2021): Covering select 2021-2022 Santa Fe and Sonata models with 2.5L turbo engines, this recall addressed fuel pipes from a specific production run installed with insufficient torque or improper concentricity. Dealers inspected and either retightened or replaced the fuel pipe at no charge.

The vehicle is experience severe, progressive engine oil consumption, completely depleting its engine oil below the safe operating limit ("Low" mark on the dipstick) every 500 miles. This creates an imminent risk of sudden engine seizure, catastrophic mechanical failure, and sudden stalling at highway speeds. The authorized dealers (Safford Hyundai Manassas) and corporate case management (Case #43193472) have failed to fix the issue after multiple visits. Furthermore, dealership service staff explicitly instructed me that I must continue operating the vehicle for an additional 1000 miles even if the oil falls below the safe "Low" limit to satisfy corporate test parameters. Forcing a consumer to drive a vehicle with depleted engine oil is a severe safety hazard to myself and other drivers on the road. The manufacturer is also underreporting oil consumption volumes on service invoices to avoid warranty repairs.

I do not know what caused this. Here is what happened. While parking the car suddenly accelerated, over the curb, on the sidewalk narrowly missing the building because I turned hard right to avoid the building and I was able to brake to a stop glancing off a concrete pillar. We could have been hurt crashing into the wall/windows, anyone on the walk would have been hurt & anyone in the store could have been hurt. The car was towed to Hatchette Hyundai-East waiting to be looked at. There is no police report because it was private property and no damages except to my car. No warning lamps or messages. I remember 2 previous incidents that happened recently. While driving in normal city traffic, my passenger asked if I had speeded up? It was morning traffic, so I didn’t really think about it. Later that day while returning home there was a weird thing that happened. Again, in traffic, the car engine did something weird, but I thought it was the car reacting to the car beside me being too close. It was like it downshifted, slowed down and then resumed normally. The only other time I had any problem was on May 9th near Lawrence, Ks. The car began vibrating and felt like it was going on rumble strips when I accelerated and did not get up to speed. If I let off the gas it quit. I had the car taken to McCarthy Hyundai-Lawrence, Ks. They diagnosed an issue from the computer codes and completed repairs having the car from Monday until Wednesday.

At times the engine will freeze up, stall the car while driving, or the car will altogether turn off when at a stop sign or light, while the car is still on. I've had the oil changed before the mileage indicated expired because the engine light came on and I was told the car had no oil at all when I know the oil was just changed within a 3 months time frame.

At approximately 42,000 miles, the AC system on my 2020 Hyundai Santa Fe suffered a potential immediate and premature failure, creating a severe driving safety hazard. The AC expansion valve began actively leaking refrigerant inside the dashboard, rendering the climate control system completely inoperable of normal operation. In Florida's high humidity and heavy rainstorms, this loss of proper AC function means the windshield defogging/defrosting mechanism fails to dehumidify cabin air. This results in sudden, severe window fogging while driving, heavily obstructing visibility and creating an imminent crash risk. Furthermore, as a senior managing multiple health conditions, a gradual, then total loss of cooling in extreme Florida heat poses a direct medical and physical safety hazard. The independent repair facility that fixed our vehicle noted an alarming pattern, servicing about 6 newer Hyundai models from our car's age group for similar AC failures and expansion valve leaks within a single month. Because an expansion valve is designed to last the life of a vehicle, this failure at 42,000 miles—combined with active industry investigations into internal Hyundai compressor degradation shedding debris downstream in the AC system—strongly indicates a systematic material defect. We have spent about $2,800 out-of-pocket to recharge the system, add dye, lose the charge again, and ultimately replace the valve inside the dashboard. Unfortunately, because Hyundai refuses to check our vehicle at their expense to find and remove potential Teflon or metal filings caused by this widespread compressor issue, and if needed, replace the compressor and other compromised components, this internal degradation can continue to cause recurring component leaks and damage at our unaffordable expense, while continuously releasing refrigerant into the air.

Some Hyundai vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

Some vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin outlines the combustion chamber cleaning procedure for vehicles diagnosed with this condition. All internal combustion engines consume some engine oil during normal operation, depending on driving conditions and mileage, and this procedure should only be performed when deemed necessary based on inspection and diagnosis of the vehicle as outlined in TSB 26-EM-015H, Engine Oil Consumption – Inspection & Repair Guidelines, or the latest revision.

Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.

Certain Santa Fe (TMA), Santa Fe Sport (AN), Sonata (LFA), and Tucson (TL) vehicles equipped with Theta II engines may exhibit elevated engine-out emissions. The California Air Resources Board has determined that these vehicles may be releasing air pollutants which exceed Federal and California standards.

Certain Santa Fe (TMA), Santa Fe Sport (AN), Sonata (LFA), and Tucson (TL) vehicles equipped with Theta II engines may exhibit elevated engine-out emissions. This bulletin provides instructions for updating the Engine Control Module (ECM) to address this condition.

Following completion of Service Campaign 9C2 (Theta II Emissions Improvement), certain vehicles may exhibit a brief hesitation or rough shifting condition during cold start operation. If present, this condition is expected to occur only within approximately the first 1-3 minutes after engine start, while the catalyst is reaching its normal operating temperature.
