What will happen if P0455 code is not corrected on 2008 Kia LX

That code ( P0455 - Evaporative Emission Control System Leak Detected (gross leak/no flow)) is for an item that's part of your emissions control system. Chances are when you take it in for inspection they will fail it due to the presents of this code. It might also be causing the MIL flag to be set, which is something they look for also.

Error codes po454 and po455. What do I have to do to fix these?

Any chance it occurred soon after filling up or adding fuel. ? Start by removing gas cap, cleaning the seal good on it, as well as threads and surface where cap seals in filler neck. Quite often it's just a bad/loose seal at gas cap. If that doesn't do it, you may need to replace cap, but check all your vacuum lines etc, just in case, if cleaning and making sure cap is tight doesn't do it.

Evap Emissions Leak

This can be because the Gas cap is not holding the pressure. I would start there first.
