The problem is the control switch itself ,
There is no need to replace the switch it can be cleaned as the contacts
get pitted and fail .
All that is need is to clean the contact with the 2000 paper or 1500 what i use .
This happens on all the models with electric seats if KIA or Hyundai .
When you have the control switch out you need to open it up and clean off the contact with the 1500 paper,
Not sure on your Gensis but on some you don't need to remove the seat , the switch will remove
with the seat still in the car .
