Every once in a while some one on one site or another 'discovers' this minor annoyance and goes sem-ballistic about it. It's been present since the Gen2's first arrived and it comes and goes in nearly every vehicle.
 
It's an intentional design parameter.
 
Now because it is intentional and since it does annoy some owners, apparently Toyota has modified the fuel tank design for the TCH and the HH. Whether the Gen3s will have the same design or still have the bladder will only be known in several weeks. For the present in the Gen2's it is what it is - intentionaly - and hundreds of thousands of owners enjoy the vehicle every day with little or no annoyance.
 
As I noted after 93000 miles I've encountered it maybe 3 times and one of those was due to the pump I'm certain.

Filling up your tank is not the only problem.
 
If you leave your Prius at an airport for two weeks you will come back to a dead battery. That is, unless you disconnect your battery.
 
The highway mileage is based on 55 mph UNDER IDEAL CONDITIONS. So don't expect to get highway mileage as posted on the window sticker. That is, if you want to stick your neck out on a interstate at 55 mph. No me.

Look folks. There are various factors that are part of the big picture. I too have well over 93K miles and have experienced the fill-up issue. More often than not it was because the fuel pump was excessive of flow. When I squeezed the nozzel to a slow fill it worked much better. I've never been able to fill to the max (11.9 gallons) The most I ever put in was 11.2 gal's. That was after 26 miles on flashing "E". As to mileage I just know that it varys. I get as good as 51 mpg's in summer and 43 mpg's winter. Head winds even reduce it to upper 30's sometimes. What I think is the most important highlight of the Prius is the overall trouble free hybrid that it has proven to be. I've owned over 50 cars and never had such success and worry free transportation before.

I agee with the previous post. The car is very reliable, gets great mileage and most important of all has 70% less greenhouse gas emissions. It also is a lot of fun to drive. Getting ready for my 5th round trip to FL from MA in my Prius and I am really looking forward to it. In the winter the bladder tank does not take as much as it does in the summer, and in the winter the mileage is lower, this is something that is a fact. It would be interesting to find out if the bladder tank functions like it should for Toyota engineers in spite of the issues we may have from time to time. New Prius owners should give the car a chance for you to understand its capabililties. If in the end you'd prefer something different, go back to one of the other car companies, but remember this is 2nd-3rd generation technology while Ford is using Toyota's first generation.

Filling up your tank is not the only problem.

Two inaccurate statements above....accuracy is important in all discussions.
 
If you leave your Prius at an airport for two weeks the 12v battery will NOT be dead if you return....and....you DO NOT have to disconnet it before leaving it unattended for a period of 2-4 weeks.
 
This is the accurate information: If you are going to leave your vehicle undriven for up to FOUR weeks then disabling the 5 proximity sensors in the SKS is recommended. This is done by pressing the 'KEY' button under the steering wheel it takes about one third of a second.
 
IF you are going to leave the vehicle undriven for more than 4 weeks it is recommended to disconnet the 12v battery.
 
The highway mileage was NEVER estimated at 55 mpg. At no time. Under the original EPA figures it was always estimated at 51 mpg if one drove according to the EPA test parameters. This is absolutely accurate. I've done it every day for the last 3 yrs and 95000 miles.
 
However...if your personal preferences or driving situation have you driving at 65 or 75 or 85 mph then you cannot get 51 mpg in a Prius - or any other vehicle at the moment, the laws of physics cannot be superceded.
 
Your preferences may be for another vehicle, just keep your complaints accurate.

Thanks for clarifying - the battery concern - I've left my car in cold Canada weather for about 10 days and never had a problem - I will remember to press that button in the future if I leave the car for 2-3 weeks.
 
I also didn't know that we were allowed to drive 75 - 85 mph on the highways - I would be concerned more with an accident than running out of gaz.

I live in south Florida. I took delivery of a 2009 Prius on 2/11/2009. The air temperature was 82 F. The gas gage had one bar and began blinking as soon as I left the dealer lot. I took it to the station where I have been filling various cars (8 different makes and models) since 1995 without incident. After pumping 5.4 gallons, the pump shut off like the tank was full. I moved the nozzle around in the fill tube neck and got 11.9 gallons in the tank before the pump shut off. When I removed the gas delivery nozzle from the fill tube neck, gas began back flowing out of the tank with such considerable force and speed that my shoes and pants were soaked with fuel. I estimate one quart of fuel spilled on the driveway. I stuck the fuel pump nozzle back in the gas tank fill tube neck to reduce the back flow. That stopped the geyser effect but some fuel continued to bubble out. It took several minutes for the fuel to stop bubbling and drain back into the tank.
 
I only average 8,000 driving miles per year. Most of the time my car sits in the airport parking lot for 5 days a week. It will be some time before I have an opportunity to fill the tank again as I fly almost every week. I will post on this issue after I attempt a second fill-up.

Problems filling up! by stevegold

I have a 2004 Prius. I live at 8,000 ft in Aspen, CO. I never had a problem in 04-07 but last winter I had the same problem you and many other described. It went away by itself last spring and just came back again yesterday. I will put a bottle of gas protector in the tank this morning and keep track of my mileage driven so I can estimate what it should take to refill the tank. It is a real pain. Otherwise the car is great.

I wonder if the vent on the tank is plugged, but I also have to wonder why you spent all the extra money on a Pruis if you only drive 8K a year. Also I have never bought a new car where the dealer didn't fill the tank and I've bought a whole lot of cars.

I'm pretty sure that it was a fueling pump nozzle shutoff that was the culprit, not the car, in this case. You said that it shut off early, the first try and then you jiggled it around. I don't know if your actions might have caused the problem, but routinely, the nozzle should have shut off before the pressure built up. I had this happen once with a nearly new Mercedes S-model. It gushered probably in excess of a gallon and hadn't stopped on its own even then. I just happened to pull the nozzle out to check the level for I thought it was overdue. This was on a indian reservation station and I suspect that the nozzle hadn't been checked or maintained. If I hadn't stopped to check, with the available nozzle pressure, it could have caused some real expensive damage. The car stumbled for awhile after I drove away, but finally cleared and seemed to suffer no lasting ill effects. -- GR
