So, when I go to refuel my 2011 Tahoe the gas pump nozzle will always click off numerous times before the tank is full. I can never just lock the pump on and leave I have to constantly wait a few seconds and then start the pump again or hold the nozzle and pump the fuel very slowly. This issue happens at all gas stations so it's a vehicle issue. Is there something in the fuel tank causing the fuel to back up into the filler hose? Has anyone else had this issue??
