Filling Prius gas tank

Re:2009 Prius gas tank, capacity 11.4 gal.

Manual says when last dot is brinking, 2 gal. remain. When filling, pump shuts off at 7 gal. Only way to get 2 more gal. in is to pull nozzle almost out. Dealer says it’s the bladder. No fix. Should I believe?

Bladder??


#3

Whatever it is in the gas tank that tells the gas pump to turn off


#4

If the car is having bladder problems, I’m not sure if you should be consulting a mechanic or a Urologist.


#5

Prius gas tanks have a bladder inside.
I have heard of them failing.


#6

That’s not what the bladder is for. It’s emissions related, but if it shrinks or gets stiff, it results in reduced gas tank capacity.


#7

Does your Prius often seem like it needs to leak, only to find that the actual leakage is minimal?

It could be the result of an enlarged prostate mechanism.

Sorry.

I couldn’t help it…


#8

Have you been in the habit of topping off the tank?


#9

And the temporary fix is a foley catheter.


#10

Only 2 years old… any warranty left?

the prius design of the gas tank is notoriously poor. & the gauge is commonly known as the ‘gas guess’.
the dealers do not know how to fix it, and the corporation denies it’s a problem. BUT the 2010s don’t have the bladder, huh?!
How do I know this, terrible problems with fueling and the gas gauge, the gas pump will often just shut off repeatedly when I’m trying to fill it. I have to try to estimate how much gas it will take and try , try try to put close to that much in. I give up because my hand gets sore, I pump so slowly to get it started- all to no avail. I can’t even get it on a notch. Go after the dealer and do not desist! document every problem at the time, and bring your paperwork to the dealer. Good luck!
