Fuel gauge indicates tank is near empty but it takes less than 7 gallons to completely refill it. Consistent with this, the gauge seems to go down more quickly than fuel economy would suggest.

keeps blinking that it is empty but can't put any more fuel into it

The fuel gauge is stuck at the 6 th notch and it doesn't move after filling it up to the full tank. It's scarily driving when I don't know how much gas I have left.

gas tank is full but gas gauge only registers half a tank, recalibrated system and still registers half tank.

The fuel gauge shows three bars, but the miles to empty is showing 10.
the level gauge did not go up when fill the fuel tank.

Fuel gauge is stuck at one bar past half. I've filled it to full twice but it doesn't budge. I've driven it 300+ miles, but the gauge doesn't move up or down. I'll not fill it over the weekend to see I it'll go down.
My fuel gage is stuck on half but the tank should be full.
Fuel gauge is not reading correct
Weather has been freezing cold at night? 1000 miles on car. Fuel gauge was working before the cold weather. Now indicator says a have 1/2 of a tank of gas permanently.....it never changes. The idiot light came on saying that I needed gas...so I filled up the tank. The indicator still says that I have 1/2 tank of gas. Prius C

My fuel gauge is stuck a half full instead of registering completely full.
2010 Toyota Prius133,000
Fuel gauge was down to empty, indicate good for 20 miles, went less than 2 miles to gas station and filled up, gauge did not go up, have gone about 125 miles since (3 trips) and still reads empty, and now has a steady buzz that I want to stop buzzing.

Gas guage/display is flashing, indicating near empty. Display is saying I have enough gas for 18-35 miles. I typically get 48-49 mpg, so it means I have less than a gallon left of fuel. Yet, when I fill the tank, I can only put approximately 8 1/2 to 9 1/2 gallons, though my tank holds 11.9 gallons. I have an appointment with dealer tomorrow.

Fuel gauge will not move from a half tank mark when I fill it with gas

We filled the tank and it continues to show full. We have driven 200 miles and it still shows full. This cannot be true.

Fuel gauge indicates empty even though tank is filled.

Gas gauge recently started to read too low. Reset did not help. Dealer said they'd have to replace the fuel tank to fix the problem. That's sure not worth it!
2008 Toyota Prius102,901
Fuel gauge began reading empty (blinking) with 4+ gallons remaining in the tank. Problem first appeared when tire shop placed larger (195 rather than 185) tires on the car. Has not yet been fixed.

No fix yet, but at this time the car is showing one bar and blinking when I actually have 4 gallons left in the tank.

My fuel gauge shows three fourths fuel after I fueled up on my 2008 prius.
