A week before my gas tank expanding I heard a loud popping noise. When driving from NC to DC, my gas tank refused to take gas and my car immediately went to empty. I was stranding on the highway and has my 2020 Hyundai towed to the Hyundai dealership in Chesterfield, VA. They told me that my gas tank expanded and my back seats had popped out of place.

An independent service center advise us that the gas tank had expanded which could have put my family at risk if exploding or catched on fired. This happend on June 15th 2024 while driving, a sudden explosion coming from the back of the car was heard. Little after the explosion like sound we perceived as if air was coming through the back as if we had a window rolled down. When pulled to check, i notice that the back seat was popped up. No warning on the car was giving prior to the incident. Will take car to Hyundai dealership to have it inspect by them and have a solution.

While exiting the vehicle there was a loud pop from under the drivers seat. Upon inspection the left front weld attaching the drivers seat to the positioning bar to raise and lower the seat bottom had failed and separated completely. This causes the front seat bottom to sit at an angle and not fully attached to the structure of the car, causing a severe safety issue in the event of an accident as the driver is not properly aligned for the airbag, the seat belt no longer aligns correctly on the body, and there is a greater risk of full seat detachment in a collision or while simply driving.
