Fuel system

Kia America, Inc. (Kia) is recalling certain 2021-2024 K5 vehicles. A damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, melting the tank.

A melted fuel tank can leak, increasing the risk of a fire.

Structure:body:roof and pillars

Kia America, Inc. (Kia) is recalling certain 2023-2025 K5 vehicles. The left and right rear window trim pieces may loosen and detach.

Air bags:side/window:curtain

Kia America, Inc. (Kia) is recalling certain 2021-2023 K5 vehicles. The side curtain air bags may have been installed incorrectly, causing them not to deploy properly in the event of a crash.

Kia Motors, Inc. (Kia) is recalling certain 2021-2022 Sorento and 2021-2023 K5 vehicles. The vehicle's "fail-safe" limited-mobility drive mode may be impaired, when prompted by a transmission oil pump malfunction, which can result in a complete loss of drive power.

Loss of drive power increases the risk of a crash.

In owners’ own words

Other mileage not reported 7 mo in service
My sunroof exploded while driving on Lakeshore drive. I hear a loud boom and I almost crashed. I thought it was my tire or something else look up its my sunroof, I could have hit some one or hit something. It hasn't been inspected or anything as of yet it just happened at 6:30am. This is crazy because there was no warnings no cracks no anything. I ride with my sunroof cracked open every morning. so I don't understand.

Other mileage not reported 10 mo in service
Was driving on the highway at roughly about 70 MPH and all of a sudden heard a big explosion and found out my sunroof blew open with glass all over the back seat and inside of my car. Luckily no one was in the back seat, if there was, they would have been injured very badly.
Fuel / propulsion mileage not reported 1.3 yr in service
I was driving on [XXX] Orlando Florida on [xxx] doing approximately 70 miles an hour when a large explosion occurred out and within my car the whole car shook this happened twice within a 5 mile radius. The car was eventually brought to Kia city in Orlando, where they determined that the fuel system had failed . the valve had failed, and the fuel system tank and fuel pump had swelled and blew .This could lead to catastrophic explosion in the vehicle, and or someone catching on fire.
