Hyundai Motor America (Hyundai) and Kia America, Inc. (Kia) are contacting owners of certain 2023-2024 vehicles because these vehicles are potentially affected by a critical issue related to the electric oil pump assembly. The problem could lead to a vehicle fire.
According to the defect report, the problem lies in a Multi-Layer Ceramic Capacitor (MLCC) located on the printed circuit board within the Idle Stop & Go (ISG) electric oil pump assembly for the transmission. During the manufacturing process, the MLCC may have incurred damage from the supplier. This damage can have severe consequences on the electrical operation of the pump, leading to heat damage to the electric oil pump circuit board, connector, and wiring harness.
The consequences of this heat damage are twofold. Firstly, it escalates the risk of a vehicle fire, which can pose a significant threat to both the occupants and the vehicle itself. Secondly, there is a potential for a Controller Area Network (CAN) communication disruption for multiple onboard controllers. This disruption could lead to operational issues and compromises in the vehicle’s performance.
A range of 2023-2024 Hyundai and Kia models have been identified as being susceptible to this issue. The affected vehicles include:
The vehicles affected include:
| 2023 Hyundai Elantra |
| 2023 Hyundai Kona |
| 2023-2024 Hyundai Palisade |
| 2023 Hyundai Sonata |
| 2023 Hyundai Tucson |
| 2023-2024 Kia Seltos |
| 2023 Kia Soul |
| 2023 Kia Sportage |
Drivers may notice smoke from the vehicle’s under-body, a burning or melting odor or an illuminated Malfunction Indicator Light and other system dashboard warning lamps.
To address this potential problem, Hyundai and Kia are taking immediate action by issuing a recall. Owners of the affected vehicles will be notified and requested to schedule an appointment with their nearest Hyundai or Kia dealerships. During the inspection process, the electric oil pump controller will be inspected, and if necessary, replaced to ensure optimal performance and safety.
As a precautionary measure until the recall repair is completed, owners are advised to park their vehicles outside and away from structures. This will minimize the potential risk of a vehicle fire and provide added safety for both the vehicle and surrounding property.
For reference, Hyundai has designated the recall with the number 246, and the corresponding NHTSA campaign number is 23V-526. Meanwhile, Kia has assigned the recall with the number SC275, and the associated NHTSA campaign number is 23V-531.
