“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.”
