When filling the fuel tank with fuel the pump constantly shuts off due to pressure in the fuel tank not being released. took this in to the gmc dealership and had the fuel tank and various component replaced under warranty. the problem did not go away. it does not matter what gas station i fill up at either. it can take up to 20 minutes to fill up the fuel tank due to the pump constantly shutting off due to the pressure in the fuel tank not being released. gm dealership says there is nothing they can do for me at this point. this is a major issue with other owners as well and needs to be fixed and addressed through a recall. *tr
