While I understand your frustration, you can be sure Toyota thoroughly tested the bladder system. The fuel tank bladder is what takes the Prius the final step to being the most environmentally benign vehicle currently in mass production. It severely lessens fuel vapour escape to the atmosphere.
I felt the same way, BTW, the first time I travelled in Washington State, and attempted to fill up at a station with the "vapour recovery system". Not with a Prius, at that time I had a 4Runner. As I recall, I got 2 gal at a time in the vehicle.

I just got a Prius, so I have yet to fill the tank, but I do have a 99 F350 Diesel from Ford, and their designers in their great wisdom decided to cut costs and use the same tank for the diesel that they use for the gassers. Well, diesel doesnt have the same properties of gasoline, less vapor, less expansion/contraction, but lots of foam. There is a tube in the tank the extends a good 6-8 inches down from the top, the overflow tube. If they had shortened that tube to about 2-4 inches, it would be much easier to fill the tank. When it gets to the tube, the foam shoots out, and stops the nozzle. I have to stand there and trickle in the last 4 gallons of fuel.
Believe me, I feel your pain.

One other thing .. if you open the car, leave your keys on the seat and then close the door to go back into the house to fetch something, when you get back the car will be locked with your keys inside. Aside from "niggles" like this ( also lousy windscreen wipers ) it is a great car. Excellent engineering. Have fun. Dont try and drive it in the snow - useless. Maybe better with snow chains or studs - we dont use those things in UK.

The smartkey system is supposed to prevent that from happening. The car isn't supposed to lock unless you do it manually from inside when the fob is in it. There are a few places you can put the fob inside the car that the system can't detect it, but they are hard to find. Of course, if you don't have SKS, you can lock the keys inside.

Guess what, if the diesel fuel you are pumping "foams up" you may be pumping fuel that has too much sulphur in it. It used to foam up years ( 9-10 ) ago. Then they removed most of the sulphur. As of 15 October, almost all of the sulphur was removed ( 15ppm from 500ppm ) is all that is to be used in any new vehicle. If yours foams, it may be off-road fuel for construction equipment ( diesel #2 ).

I have the same problem with my new 2007 Toyota Pruis. I noticed it right away. I took it into the dealership and was told they were unable to duplicate the problem when filling with gas. At first, I assumed it was due to cold weather...but I've had it happen during the summer months too. I'm taking back in to have reviewed again. It's frustrating when you know you need to put in several gallons and the tank shuts off after only putting in 30 cents.

I have had a similar problem to the one "jchshade1969" described. Twice, while gasing up, the pump has cut off prematurely and at about the same time in the gasing process. I had pumped about 8 1/2 gallons when I really needed about 10. There must be an air-lock problem that makes the pump think my tank is full. I do know that if you pump too fast, it can make the pump cut off. But it stilled happened at a slower pumping rate.

I have a 2007 Prius and have been having problems with the fuel gauge registering correctly. My car will not take more than 6.5 gallons when filling up and my mileage has been cut in half. After having it at the dealer 7 times, having the complete instrument panel replaced 3 times and the entire gas tank replaced once, the problem is still there. After calling Toyota and making my complaint, they tell me it is a regional problem due to weather temps here (WV). They do not want to do anything till it gets warmer to see if it corrects itself. Has anyone else had this problem with this car?

I have a 2006 Prius with 39,000 miles. I love it. I have started having problems filling the fuel tank this winter. I live in the northeast and in December the tank started taking only 7-8 gals or so when filling up even if it was empty. It has continued all winter. I compared this to last year's fillup records and this problem did not occur, I was able to get 10+ gals in last year through the winter. I took it to the dealer and after two different technicians, the only explanation is the cold weather and stiffening of the bladder tank. They said wait until it gets warmer... They also recalibrated the computer. How frequently is this happening? As I said to the technician this is a loss of 30+ % of the tank capacity. The gas gauge shows full when I only get the 7-8 gals in and the computer and manual mileage calcs match.

I have a 2004 Prius with no prior history of tank filling problems. This winter has been unusually cold. A few months ago my wife washed the car on a very cold day. From then on, no gas would go in the tank even though the gage read only half full.
I tried 3 or 4 times but the gas would instantly overflow. I assumed the tank was full (and the gauge was wrong) and did nothing more until I had driven about 300 miles at which time the tank took 7+ gallons and the gauge read full. It has been working properly ever since. I think it was some combination of the prolonged very cold temperatures and the car wash.
