2003 Hyundai Santa Fe - Cargo Screen/ Shade will not retract back into holder. Can this be fixed? How?

Yes, but it takes a little work. After tapping out the drift pins that hold the plastic brackets into the ends of the shade, slide them off. Disassemble the shade so that you can remove the center shaft. The recoil spring is supposed to be attached to a hole on one of the plastic end bushings, but the bushing has probably cracked. Fortunately the plastic bushing on both ends are identical and the one without the spring shouldn't be damaged. Swap the bushings and reassemble everything. Remember to put 1-2 turns of tension on the roller before you put it back in the car or it will sag on you. Yes, but it takes a little work.
