I'm not quite sure about the code in Hyundai's case but it definitely relates to fuel trim...
I could try to hash down the explanation for Short term fuel trim and Long term fuel trim in this post but I think a visit to
would be more thorough and appropriate.
Basically, a high value of long term fuel trim indicates that your engine has had and will have to continue to inject a lot more or a lot less fuel to attain the correct air/fuel ratio for a proper burn, which mainly indicates a malfunction somewhere (could be lots of things)

SOURCE: loss in fuel efficiency
Check air filter. Has your driving habits changed? Or......It's unlikely but people do do it......gas theft. With prices high, people are taking a hose to steal gas from random vechiles. No bull. Try parking your vechile inside locked building, to see if that helps. If so, well, you got your soultion.

There is an EPA requirement that the amount of refrigerant required be indicated somewhere on the unit.
There are no moving parts that would cause a leak, but leaks can usually be found by looking for oily hoses, connectors, fittings, and coils, etc. The oil coats the inside of the system parts, and the leaking refrigerant will tend to push the oil out through the leak.
Unless you know the unit is low or out of refrigerant, then look for any cooling problems to be compressor related.
