Has anyone had any issue with fuel gauge not reading correctly.
On the weekend went and filled up the car, gauge was reading 1/2 full.
filled up car till the pump stopped, paid for gas drove off and noticed that the fuel gauge had not moved, still at same point before I had added fuel.

are you sure you're not looking at the temperature gauge?

serious answer: i don't know, go to your dealer.

I did go to the dealer and they did not have an answer, they said that the electronic sensors act up sometimes.

There is another post with the same problem. I think it resolved itself in the end. Give seacrh a try - it's out there somewhere...

not sure if this is normal, but when my gauge says it is at Empty and the light is on and I drive it for abour 30km, and go to fill up.. I only fill up 40 liters when it's supposed to be a 50 liter tank..

thank you, I shall look

I haven't seen that problem on this car but have seen it on my brothers F-150 when the ignition was on during fueling. It corrected itself next fillup.

Wouldn't it then resolve itself the next time the car is turned off and back on if it were just a matter of inadvertently leaving the car set to ON while filling up?

FR-S Hot Lava · 07-30-2012, 05:39 PM

No key in the ignition when I was filling it up.

Willsonk · 07-30-2012, 09:25 PM

All newish cars have a fuel "reserve"... The light will come on even though you will still have about 10 liters or so (even if on the 'E').

On my 2008 tc, it was more predictable. The bottom of the fuel guage was labeled with an 'R' for 'Refill' and had a gas pump below it. At the 'R' I still had a ways to go, but when it got to the gas pump icon.... goodbye.

One would think, his F150 didn't though. Again, no idea on this car but it doesn't seem to be the case anyways.

My light is always on before I fill up, maybe why I've avoided this

This happened to me yesterday. I ran the car down to 1/4 this weekend, and when I filled it up, it only went to just under 3/4. I re-filled today and the gauge didn't move.

Hello Roddy, did you ever get the fuel gauge issue fixed
