Everything you wrote points to a seized engine, which would not have time to set codes on a sudden event. But I hope for your sake that it's just some really weird electrical issue instead.
But if it is a blown engine, the oil change records are likely to become really important. Kia usually always wants to see the complete set of receipts, and it's highly likely they will deny warranty coverage if you can't provide that documentation to them. However, there was a recent thread from someone who was given coverage, even though he didn't have any oil change records. His dealer apparently opened it up and found clean internals with no sludge, and decided to cover the repair under warranty. That was very fortunate for him, but I'd have no confidence that most stealerships would take the high road like that.
Not many (any?) reports of the 2.4L non-GDI Theta engines seizing up. There have been multiple timing chain-related threads, but that issue would not fit the description that you posted (it would still crank, even with bent valves from jumped timing). So it might be very helpful to others in the future, if you post back the what the resolution of your Forte's problem turns out to be.
