Fountain Valley, CA – December 1, 2025 – Hyundai (OTCMKTS:HYMTF) and Kia (OTCMKTS:KIMTF) are recalling 85,043 2020-2023 Hyundai Sonata and 250,547 2021-2024 K-5 vehicles whose fuel tanks may develop a leak. This defect ups the chances of a vehicle fire and injury.
Hyundai owns a significant stake in Kia and they share some parts, engine components and engineering platforms.
Recall summary
A fuel tank has a purge check valve that regulates the pressure inside it. In the affected vehicles, the valve may get stuck and cause a pressure increase that could result in the tank touching the “hot exhaust pipe components.” Over time, this can lead to “localized melting” of the tank and a fuel leak.
Recall risks
Leaking fuel may cause a vehicle fire, significantly augmenting the risk of injury.

Background of the recall
Hyundai and Kia tried to tackle the problem by issuing a service bulletin to their dealers in January 2025. The document instructed dealers to replace the check valve when its failure triggered a check engine warning light.

The repair
The dealers will replace the fuel tank and the purge check valve and will update the corresponding software. All repairs will be done free of charge.
