| Description of the problem | I am experiencing a loud bang coming from underneath the rear of the vehicle. This noise occurs when the fuel tank is half full or less when slowing down and even when the vehicle has come to a complete stop. When the vehicle is in gear, the noise occurs driving forward or stopping at a light on a city road. When vehicle is put into park and shut off, the bang occurs as well. This issue started occurring on rare occasions in 2017. I brought the vehicle in for service, but the hyundai dealer could not replicate. In 2018, the noise started occurring on a consistent basis. When i brought it back to the dealership the third time, they were finally able to determine where the noise was coming from. The hyundai dealership concluded that it was the fuel tank expanding and contracting. The dealership explained that it's like sucking the air out of a coke bottle (crinkling noise) and afterwards pushing air back in for it to expand, making a thump like noise. The dealer claims there is no safety risk to this loud expanding and contracting of the gas tank and gas vapors. The fix is to replace the gas tank but at my own cost since there is no tsb or recall posing a safety risk. I have researched online and found several others with this same experience. |
