There is more than one recall on the tank, one for the guard, one for punctures, one for seam rust and one for fittings!
this tread covers a few of them Free Gas Tanks!
You live in one of the 21 magical states where the tanks were recalled due to salt corrosion, so you should have no problem!
But check the Kia Tech site (Global Service ways) do some homework, get to TSB numbers, go back to the dealer when they are busy! present the recall info to them, if they still won't help, in a loud voice so everyone can hear question the fact they know their product is decfective, and have recalled it, but why won't they replace yours ??? The squeeky wheel gets the oil!
