Does anyone know a mechanic or shop who would be willing to work on an electrical issue with my Hyundai Genesis?

Hi everyone, I have a 2015 Hyundai Genesis that is having power steering issues. Ive already figured out that the issue is because one of the wires to the power steering motor is shorting out. The wire needs to be traced to see where the ground issue is. Or a new ground needs to be ran.

I have pleaded with the Hyundai dealership here to help me out but they have refused to look at the car because by their own admission they do not have a good track record of working on the Genesis (Even though its a Hyundai product). I've been without power steering for months now and am pretty desperate for help. I've probably spent more than a dozen hours, including replacing the entire power steering motor myself, to finally find out what the real issue is. Basically, I've done 90% of the work but I really need help getting over the finish line to repair the car. Does anyone know a shop or mechanic that would be willing to look at the car? Thanks!
