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 level gauge did not go up when fill the fuel tank.
The fuel gauge shows three bars, but the miles to empty is showing 10.
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.
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.
Fuel gauge is not reading correct
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.
My fuel gage is stuck on half but the tank should be full.
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 never changes. The idiot light came on saying that I needed 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.
Fuel gauge will not move from a half tank mark when I fill it with gas
Fuel gauge indicates empty even though tank is filled.
Gage drops and when say empty can only fill 6.5 gallons - the dealership didnt have a solution and told me next time it drops to come by...
Problem noticed for quite sometime probably around 100K, indicator does not reflect actual in fact tells me I'm empty and is blinking but only can get 8 gallons of gas in it.
Fill up tank and bar doesnt move.
We filled the tank and it continues to show full. We have driven 200 miles and it still shows full. This cannot be true.
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!
