Yeah, I called the preferred line the day before my appointment, and what do you know, this time they heard the rattle. Had the car there overnight one other time, and also mentioned the sound at every oil change there, this time they opted to do the repair. Not sure it the kia line did all that for me, but I like to think so. They got the parts same day, so they've been working on it for 2 days. Picking up the car Saturday if there are no complications between now and then.
