Keep us posted if you end up getting it resolved via the dealer, we could all use the input on trying to understand where the problem lies.

 

This JUST started happening to mine on the last couple fillups too. I'm used to the gauge being ABOVE the "F" mark after a fill up, and now, suddenly it seems, when I fill up it's BELOW the "F" mark (and not just a little bit). The last time I was convinced the pump stopped too early so I got out to fill up some more, got 50c worth of gas in there and wound up with gas all over my shoe

I think I'll mention it to the dealer when I take mine in next week for it's 22.5k too.

 

My car was always quirky at the pump during fillup. I had to hold the trigger about halfway to keep the pump running. Months later it got progressively worse because the pump would stop before the tank was actually full. It got so bad that I could never completely fill the tank. I took it to the dealer and they replaced my carbon canister. Another car had the same issue while mine was at the dealer and the carbon canister replacement fixed it on both cars. The other car had it so bad that it wouldn't take any gas and it only had about 1100 miles on it! Apparently sometimes the canister fills up and doesn't allow a path for the vapors to escape thus triggering the pressure sensor at the gas pump to stop pumping gas. So far so good, two clicks at the pump and I'm reading above "F"
