On XXX, while traveling to [XXX], I experienced serious fuel system problems after filling my vehicle. The fuel gauge fluctuated from full to empty, and a loud pop caused the rear seat, where my two children were sitting, to lift upward. The vehicle would not accept more fuel despite the empty reading. I called AAA, but before the tow arrived, the gauge returned to normal, so I continued my trip. After returning to [XXX], I checked my Kia app and discovered active Recall SC356 describing a damaged check valve that could cause fuel tank expansion, rear seat lifting, and abnormal fuel gauge behaviorâthe same symptoms I experienced. On XXX, I brought the vehicle to The Kia Store in…

As I was driving down the road, I began to hear a loud, forceful noise. I assumed it was something in my trunk rolling against the rear seats. The noise kept getting louder, and I pulled over, very frightened, as several warning lights came on, including the low fuel light and check engine light, and the fuel gauge needle was past âE.â Before the incident, the GPM reading was 400. After a while, I made it home, but the car started making loud noises and then died. Thatâs when I noticed my back seats were lifted. I called Kia customer service and had the car towed to the Kia dealership on Seigan Lane, where it is now. Something needs to be done about this.
