is anyone having this problem on their 2.5i, not sure if its normal or not, probably not. When I fill up my tank and start driving it for a couple of days, I use about a quarter tank of gas, then the next day it goes back up to full again. Then slowly goes back to normal after I drive it for 10 miles or so. This happened to me two time already.

do you drive in a place with a lot of steep hills?

I would bet that it has something to do with this issue. I'm not exactly sure of where it measure the level of gas in the tank but as you are on a hill it would change the level and show you a different reading. You can try to see if this happens on roads that are relatively flat, or since you still have warranty nothing wrong with checking it out like coopwrx said.
