2007 Toyota Prius 125,000 mi,
I cannot fill up the gas tank beyond 4 or 5 gallons when the fuel gauge is on 2 bars. The fuel gauge reads full but is not and the gas hose keeps clicking off like the tank is full. This is the first time that this has happened to me. 11-5-2015 Did anyone find a fix for this issue?
prius gas gauge stuck in empty position.

Filled up but car did not register it. Remained on 4 bars
2006 Toyota Prius 160,000 mi,
The miles per gallon says i am getting 47 mpg and i have only driven 150 miles from a full tank but the gas gauge shows i am at half tank. The gas gauge is wrong. It is going down much faster than normal. I should be at 7 bars or maybe 6 bars not 5 bars. What can i do to recalibrate the fuel gauge?
One year ago, the fuel gauge dramaticallly changed, going down much faster than the mileage would have indicated. Keeps getting worse, now starts blinking as though empty and still has about 4 gallons in it. The Toyota dealer is telling me it can't be fixed. They did try to recalibrate it but that didn't fix it.

gas gauge shows half a tank after fill up and show empty with 6 gallons left

I have run out of gas three times, once in a dangerous place because the fuel gauge doesn't work anymore. They told me it would cost $1000.00+ to fix it, so I just watch the miles traveled, but that is a pain too.
2010 Toyota Prius 126,000 mi,
I filled up my Prius with gas when the gas gauge read flashing low, 1 bar. Driving home I noticed the fuel level hadn't changed and still flashing! Got on line to find out about the problem and it turns out this is a common problem! I know usually this requires a fuel tank removal and replacement of the fuel gauge sensor and filter which is very costly. I'll shop around for some simpler answers like recalibration and electrical connections first... BR

Gas gauge was at 1/4 full and I put 5 gallons in tank and gauge has not moved. I have made 3 trips equaling about an hour worth of driving. My 2008 Prius Touring should be almost full. JTDKB20u987765535

The fuel gauge got stuck at 4 bars with a full tank of gas. The milage on the dashboard is not in sync with the one on the front panel either.

shows empty when still 5-6 gallons in tank
2008 Toyota Prius 100,000 mi,
Gas gauge tells me the tank is empty after only going through about 300 miles, then I can only refill 6 or 7 gallons and the problem repeats itself. I'm sure there are probably 3 gallons left when it says it is empty but I'm not eager to test that theory.

When I have 2 bars left on my Prius, i could only get 3.1 gallons into the tank. I opened the trunk and sat on the bummer several times and I was able to get another 1.5 gallons into the tank. So I managed 4.8 gallons for 225 miles. It appears that this problem is getting worse. When i bought it used in Aug 2014, it worked fine. Last winter, 2014-2015 I could only get about 325 miles per tank with an average of about 48mpg. Now its down to 225 miles at 43mpg.
