Other Fuel System Tank Filling/charging problems of the 2005 Nissan Sentra

Cannot fill gas tank normally. With a 1/4 tank, there is back-fill that causes the gas pump to 'click' off as if it is full. Other times, you hear the 'swooshing' sound of a back-fill, and gas has come flying back out at me while 'attempting' to put gas in the car - severe hazard!!! checked the code and sure enough, like thousands of others, voila - it's the evap canister vent valve malfunction. . . In this case, it's 'closed'. It can take up to 8 minutes to put 2 gallons worth of gas in, needless to say, vapor fumes are strong, and gas dribbles out. Filling up this vehicle is a pain in the _____. It appears to be a well documented issue with Nissan vehicles and it appears to me, Nissan does not want to take care of this issue.
