Engine shut off while driving and will not start, check engine, oil and battery lights turned on

Hello, this sounds like an interesting situation considering the vehicle is not that old. Have you actually checked down at the starter motor connections to see if something may have shorted out or are there any melted wires down there? And how low on oil was the car? If you had to put 2+ quarts in the vehicle that's a big concern. Are there any obvious leaks you can, see? I'm going to post the starter circuit wiring diagrams in a minute as well.
In the third diagram, I'd like you to check that Start Fuse (7.5amp) too.

It is concerning though, being that this is a 2.4liter engine, it probably only takes 4.5 quarts and being halfway low on oil with no leaks at all is a major concern.
I'd recommend attempting to rotate the engine over by hand, with a socket and large bar on the crankshaft bolt. This is the way to assure its not seized up, which it may be.
I worked for Kia and these engines are semi fragile, running on two quarts of oil could have caused major damage, but I really hope it did not. The oil light did not come on before any of this happened.

I would definitely recommend trying to turn the engine over by hand at this point, if the oil pump failed or anything like that and you start the engine, it will destroy the engine without oil pressure.
