Kia has issued a significant recall affecting hundreds of thousands of its K5 sedans due to a potential fuel tank defect that could lead to dangerous fuel leaks and fire hazards. The recall, designated 25V794 by the National Highway Traffic Safety Administration, covers specific model year 2021-2024 Kia K5 vehicles equipped with 1.6-liter turbocharged gasoline direct injection engines.
The issue stems from a deteriorating component within the vehicle’s evaporative emissions system that can allow pressurized air to enter the fuel tank, causing the tank to swell and potentially rupture. Kia’s remedy involves a free dealer repair that replaces the defective part and inspects the fuel tank for damage. Owners of affected vehicles are being contacted via first-class mail with instructions to bring their vehicles to authorized dealerships for the complimentary repair.
This recall represents one of the more substantial safety actions affecting the Kia K5 nameplate in recent years, with the automaker addressing concerns that had been documented through multiple technical service bulletins before the official recall was filed with federal regulators in 2025.
Which Kia K5 Models Are Affected by the Fuel Tank Recall?
The recall encompasses 250,547 model year 2021-2024 Kia K5 sedans manufactured at Kia’s plant in Georgia between March 27, 2020, and January 23, 2024. The affected vehicles are specifically those equipped with the 1.6-liter Turbocharged Gasoline Direct Injection engine, internally known as the Gamma II powertrain. Not every vehicle within this production window is necessarily defective, as Kia estimates the defect rate at approximately 1 percent, meaning the issue does not affect all vehicles built during this period.
Some technical service bulletins narrow the affected production window to vehicles built on or before October 17, 2023. The official recall documentation, however, covers the broader March 2020 through January 2024 range. Dealers can verify individual vehicle status through Kia’s diagnostic systems.
Kia has not included GT or higher-performance variants of the K5 in this specific recall, as those models typically utilize different powertrain configurations. The 2025 model year K5 is unaffected because it lacks the 1.6-liter turbocharged gasoline direct injection engine that is central to the defect.
- All 2021-2024 Kia K5 sedans with 1.6L T-GDI engines fall within the recall scope
- Production dates span from late March 2020 through late January 2024
- Approximately 1 percent of vehicles within the production range are estimated to have the defect
- 2025 model year vehicles are not included in this recall action

What Caused the Kia K5 Fuel Tank Recall and What Are the Risks?
The root cause of the recall lies within the vehicle’s evaporative emissions system, specifically the purge control solenoid valve check valve. Over time, this component can deteriorate and lose its ability to prevent reverse airflow. When functioning properly, the check valve should allow vapor to flow in one direction only, from the charcoal canister to the engine intake for burning during the combustion process. When the valve fails, pressurized air from the intake manifold can travel back through the system and enter the fuel tank.
As this pressurized air accumulates within the sealed fuel tank, internal pressure increases and causes the tank to expand or swell. This swelling can damage surrounding components and potentially lead to fuel leaks at seals, fittings, or at the tank itself. The combination of leaked fuel and potential ignition sources creates a fire risk that prompted the recall.
Fire Risk and Safety Concerns
The primary safety concern centers on the potential for fuel leaks that could result in vehicle fires. Kia has issued a consumer notice advising affected owners to park their vehicles outside and away from structures, a precaution consistent with the do-not-drive advisories typically reserved for the most serious safety defects. Beyond the fire hazard, tank swelling can also damage associated components including fuel lines, sensors, and the fuel pump assembly.
Kia has advised affected owners to park their vehicles outdoors and away from other vehicles or structures while the recall is pending. This precaution reflects the potential fire risk associated with fuel tank swelling and potential leaks.
Additional Symptoms and Complications
Vehicle owners may notice several symptoms indicating the presence of this defect. The most apparent symptom is the inability to refuel the vehicle normally, as the swelled tank cannot accept fuel at the normal rate, causing the pump to click off repeatedly. The system may also trigger diagnostic trouble code P0451, which relates to evaporative emissions system pressure sensor performance.
Beyond the immediate safety risks, the malfunction allows unburned fuel vapor to escape into the atmosphere, potentially causing affected vehicles to exceed federal and California emissions standards. This environmental compliance issue further underscores the need for timely repair.
- Fuel tank swelling visible as distortion or bulging
- Difficulty refueling due to automatic pump shutoff
- Fuel odor around the vehicle
- Illumination of check engine light with code P0451

How Do I Check If My Kia K5 Is Part of the Fuel Tank Recall?
Owners of 2021-2024 Kia K5 vehicles can verify whether their specific vehicle is included in this recall through multiple methods. The most direct approach involves using the Vehicle Identification Number to check against official recall databases maintained by both Kia and the National Highway Traffic Safety Administration.
VIN Lookup Methods
The Vehicle Identification Number can be found on the driver’s side dashboard, visible through the windshield, or on the vehicle registration and insurance documents. Once located, owners can enter this 17-character identifier into the NHTSA recall database at nhtsa.gov/recalls to verify whether their vehicle has any outstanding recalls, including the 25V794 action.
Kia maintains its own owner portal where VIN lookups can confirm recall status specifically for that vehicle’s history. Owners may also contact the Kia Customer Care Center directly by telephone to speak with a representative who can verify recall eligibility using the VIN.
Authorized Kia dealers use the KDealer+ system under Service → Warranty Coverage → Campaign Information to verify whether individual vehicles are affected and whether the recall repair has been completed. Owners without dealer access can obtain this information by calling Kia’s customer service line or visiting the official recall information page.
