If the 2008 Santa Fe uses the same cartridge-type filter as other recent Hyundai/Kia models, check that the spine hasn't just come off the filter cap.
The spine does come off the cap and just snaps back in. No big deal and it's not broken. Just needs to be snapped back into place. If you have ever done your own oil changes, you will find the spine is a loose fit in the cap and wobbles around some, and will readily detach if you pull on it. Dunno why it does this.
If your oil change person had never encountered a detached spine before, I could see how they might think it was broken off.
