Hyundai Palisade Electric Oil Pump Issue

Posted on by

Hyundai Motor America has announced a safety recall affecting a limited number of 2025 Hyundai Palisade vehicles due to a potential problem with the controller for the electric oil pump (EOP). The issue, which may cause an electrical short and increase the risk of a vehicle fire, is attributed to an insufficient seal on the EOP controller housing.

According to Hyundai, the problem was first identified in March 2025, when the company was notified of a potential issue involving the electric oil pump installed on a model year 2025 Palisade produced in Ulsan. An investigation revealed that a damaged spring in the tooling used during manufacturing may have compromised the hermetic sealing of the EOP controller housing, allowing moisture to accumulate on the printed circuit board and increasing the risk of electrical shorting.

The National Highway Traffic Safety Administration (NHTSA) was informed of the issue, and after reviewing the findings, Hyundai decided to conduct a safety recall of all affected model year 2025 Hyundai Palisade vehicles in the U.S. The recall aims to replace the EOP controller and associated wiring harness, if necessary, to prevent any potential fires.

Symptoms and Precautions

Drivers of affected vehicles may notice a burning or melting odor or an illumination of the Malfunction Indicator Light. While owners can continue driving their vehicles, Hyundai recommends parking them outside and away from structures until the recall remedy is completed as a precautionary measure.

Recall Remedy and Notification

Hyundai will notify all owners of the subject vehicles by first-class mail, instructing them to bring their vehicles to a Hyundai dealer for replacement of the EOP controller. The recall remedy is expected to begin on July 4, 2025. Owners can contact Hyundai’s customer service or visit the NHTSA website for more information on the recall.

The recall number assigned by Hyundai is 278, and the NHTSA campaign number is 25V-291. Affected owners are encouraged to follow the instructions provided in the notification letter to ensure their vehicle is repaired promptly and safely.

In conclusion, while the electric oil pump issue affects only a small number of 2025 Hyundai Palisade vehicles, it is essential for owners to be aware of the potential problem and take necessary precautions to prevent any accidents. By following the recommended steps and cooperating with Hyundai’s recall efforts, owners can ensure their vehicle is safe to drive and minimize any risks associated with this issue.

Hyundai And Kia Loss Of Drive Power – Transmission Oil Pump Malfunction

Posted on by

Hyundai and Kia will be contacting the owners of certain 2021-2023 vehicles because of an internal fault affecting the electric oil pump in their transmissions. These automobiles are equipped with 2.5L turbocharged gasoline direct injection (T-GDI) engines and 8-speed dual-clutch transmissions (DCT)

Hyundai first became aware of the problem in September 2022 when the NHTSA’s ODI contacted them about a 2022 Hyundai Santa Cruz allegedly experiencing a loss of motive power while driving at various speeds. An investigation into the problem identified an internal fault with the DCT’s high-pressure electric oil pump as the likely cause of the vehicle entering “fail-safe” driving. Based on the information received, Hyundai decided to conduct a recall for affected vehicles. Because the same components are used on certain Kia vehicles, Kia also decided to conduct a recall.

The vehicles affected include:

2022 Hyundai Elantra N
2022 Hyundai Kona N
2022 Hyundai Santa Cruz
2021-2022 Hyundai Santa Fe
2021-2022 Hyundai Sonata
2021-2022 Hyundai Veloster N
2021-2023 Kia K5
2021-2022 Kia Sorento

According to the defect report, “The electric oil pump within the 8-speed dual-clutch transmission (DCT) may experience an internal fault due to insufficient soldering of a component of the electric oil pump circuit board. As a result, the subject vehicles may set a diagnostic trouble code with warnings and allow the vehicle to be driven normally for 20-30 seconds, followed by complete loss of motive power due to disengagement of the transmission drive gears.” If this happens, drivers will hear an audible warning chime, the message “stop safely immediately” on the instrument cluster and an illuminated malfunction indicator light (MIL).

Hyundai has received 229 unique incidents in the US related to this problem. Kia has identified 36 alleged incidents of loss of motive power due to an internal fault with the electric oil pump. Hyundai’s number for this recall is 236 and the NHTSA campaign number is 22V-746. Kia’s number for this recall is SC250 and the NHTSA campaign number is 22V-760.

BMW Possible Engine Failure

BMW will be contacting drivers of certain 2013 BMW M5 and 2013 BMW M6 coupe and convertibles high performance vehicles with twin turbocharged V8 engines. According to reports filed with the National Highway Traffic Safety Administration (NHTSA) certain vehicles may be equipped with an oil pump that may fail because of a problem with the manufacturing process. The oil pump drive shaft could separate from the rotor starving the engine of oil. If the vehicle is not pulled over immediately, the engine will overheat and eventually seize. BMW will be notifying customers of the the problem starting this month, and will replace the oil pump free of charge. Owners wanting more information may contact BMW at 1-800-525-7417.
