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.
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.
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.
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...
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.
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.
After driving 250-300 miles on a full tank, Gas gauge flashes empty, but will only take 6-7 gals to fill. (Not 11+).
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
We filled the tank and it continues to show full. We have driven 200 miles and it still shows full. This cannot be true.
The fuel gauge is not correctly responding to fuel consumption after filling fuel tank to full. It continues to register as full even after driving 100 miles.
