Thank you for the responses. I have 89,000 miles on my 2011 KIA Sorento so this type of thing is no longer under warranty.
STEP 1:
Purchase Part Number 82610 1U000 - HDL ASSY-FR DR (Driver Front). $49.00 from the dealership.
STEP 2:
I pulled the door panel as shown in the video here:
STEP 3:
Remove 4 screws on back panel of driver door panel to release door lock assembly.
STEP 4:
Depress (1) tab which holds the back plate and cable assembly to the door lock assembly.
STEP 5:
Reverse of all other steps.
10 minutes and done.
LESSONS LEARNED:
It appears that KIA has modified the way they chrome dip this handle. The original 2011 handle had a chrome applique or dip "seam" on the top of the handle...where you are grabbing the handle everyday. The modified part has the seam on the bottom edge, where you are likely never touching the door handle.
