Fuel Hoses Lines/piping And Fittings problems of the 2008 Toyota Prius

2008 Toyota Prius: refueling started to become a problem at 35,000 miles. Tank would not refill completely and gas is "burped" out tank. Very frustrating refueling because gas hose clicks off repeatedly even though tank is not full. Typically tank will take an additional 2 gallons of fuel after the first time it clicks "full". It takes 5 minutes to put in last 2 gallons and then fuel bubbles up and pours out of tank. I could see the air bubbles working their way to the surface as the gas tank burps out the fuel. The bladder gas tank is clearly defective and it is impossible to know when tank is full. Michael's Toyota of bellevue, washington has been worthless - first telling me they aren't aware of this issue and they had no problem refilling the car and the last time telling me there is nothing they can do and I should call Toyota. Great customer service. . . Thanks heavens the car is out of warranty because I have no interest in doing further business with them. Toyota should acknowledge this defect and replace the bladder gas tank with a regular version.
