2013 GMC Acadia Noise When Filling Gas Tank
I have a 2013 GMC Acadia SLT that has a klank noise when I fill the gas tank. When filling the gas tank, at any gas station, a few seconds before the gas pump handle automatically shuts off, there is a fairly loud bang or klank noise that seemingly comes from the gas tank of the car. I can even feel it when I'm leaning against the car. Everything works fine and the gas pump handles shut off like they are supposed to. This is a relatively new noise and happens every time I completely fill the tank. What could cause such a noise?
