Update. Finally called the manager of the service department with my complaint yesterday. He was understanding and thanked me for the call. He was going to look into it so that when I bring her in for the new engine computer install (recall - anyone else have this??) they can finally fix the fuel sensor issue as well.
Today, the tech that originally wanted to take my Stinger home to run some gas out of the tank last month, told me the manager had him order a new Fuel Sender Lever. The computer came in today and the new sender lever should be in Friday. Of course, they do not have a loaner for me until 12/3 so I scheduled the appointment for over a week out.
I hope this takes care of the problem. If not, I have documented all of the work, mileage, names, issues, ect. and will be contacting a Lemon Law attorney to prepare the required letter to Kia Corporate.
