Well, its happened several times now. Whenever I have a low-fuel light and I do not fill up completely, but instead put say, 10 litres in, I start the car again and the gauge does not go back up. It stays where it was, low fuel light and all, and I drive it for a while knowing I just put gas in it. As I drive, the gauge very very slowly goes up at what seems to be the same rate Im burning fuel, as if the gauge flipped upside-down. Anyone else see this?

Make sure that you crank the gas cap tight a couple turns AFTER it starts clicking. I had a similar faulty reading with my older WRX, but found that you need to tighten the cap beyond what I thought was enough.

Faulty fuel gauge or bad sending unit from your fuel tank.....sometimes cars will do that when it's ultra cold outside. Regardless though, this is NOT something you should be experiencing with a new car. If it does it consistently, I would take it in and have it fixed. Nothing like being set on the side of the road with an empty tank of gas.....SUCKS!!!!

It first started happening when it was quite cold out, but it has since warmed up and the behavior isnt any different. I usually filled it right up so I didnt notice. It seems if I put in enough gas to get it to about half a tank, it acts as normal.

My STi does this as well, but I have found that it only occurs when I leave the key in the ignition while filling the gas tank. If I remove the key during the fill, then the gas gauge will jump to correct amount when the car is started.

I don't buy that for a second. Mine has never done anything less than a full and rapid sweep to the correct level. I'd have em replacing that baby....

Now...I have been having a problem with the filler clicking off, acting like it's full and then when I get inside, come to find out it really down around the 3/4 mark. I seen to have to fight in that last 1/4 tank.

it's simply how the senders work. if you fill it up with the ignition on, it goes very slowly - i find that it doesn't appear to be moving, then next thing i know it's up high. i wonder if the sender just sends a gas level signal to the gauge every x amount of seconds, instead of a real-time value. if i have the car off, then get in after fill-up and turn it on, bang - straight up. when you start the car you're resetting the guages to whatever they're supposed to be. watch them the next time you turn the car on when it's warm; you'll get the sweep, then they'll bounce to their current readings.

I think this is a problem with the vent on the filler neck. If you ease off on the pump for the last couple of gallons you can get a full tank.

Mine will puke gas if I keep the pump going full blast.
