If You Own a Hyundai or Kia, Your Fuel Tank Could Be at Risk

Urgent Recall Alert: Kia and Hyundai Fuel Tank Issue Poses Fire Risk

While it’s uncommon for two different car manufacturers to issue recalls for the very same problem, it absolutely can happen. Recently, the National Highway Traffic Safety Administration (NHTSA) published reports concerning potentially dangerous Kia and Hyundai vehicles. If you own one of the models mentioned, you should be aware of a potential fuel tank issue.

Why Are Kia and Hyundai Issuing Fuel Tank Recalls?

The NHTSA reports indicate that both Kia and Hyundai vehicles share a common defect: a faulty check valve. This defective valve can allow air to enter the fuel tank, causing it to expand. The expanding tank may then come into contact with hot exhaust components, leading to melting. This is not merely an inconvenience; it’s a serious safety hazard. The NHTSA explicitly warns that “a melted fuel tank can leak, increasing the risk of a fire.” This recall addresses a potentially life-threatening situation, emphasizing the importance of taking prompt action if your vehicle is affected.

Which Kia and Hyundai Vehicles Are Affected by the Fuel Tank Recall?

The fuel tank recall impacts a significant number of vehicles across both the Kia and Hyundai brands. Knowing the specific models and years affected is crucial for determining if your car is at risk.

Kia Vehicles Affected:

Over 250,000 Kia vehicles are potentially affected by this issue. The specific models included in the recall are:

  • 2021 K5
  • 2022 K5
  • 2023 K5
  • 2024 K5

Hyundai Vehicles Affected:

Hyundai’s recall impacts over 85,000 vehicles. The following models are included:

  • 2020 Sonata
  • 2021 Sonata
  • 2022 Sonata
  • 2023 Sonata

If you own one of the vehicles listed above, it is crucial to pay close attention to upcoming communications from Kia or Hyundai. Owner notification letters are scheduled to be mailed out in mid-January 2026. These letters will provide confirmation as to whether your specific vehicle is included in the recall based on its Vehicle Identification Number (VIN).

How Will Kia and Hyundai Resolve This Fuel Tank Fire Hazard?

Both Kia and Hyundai have outlined a similar approach to address the defective fuel tank issue. The repair process will be conducted at authorized dealerships and will be performed free of charge to the vehicle owner.
