Here is a description of your system. I would suggest with starting to see if there are any codes in the system. The reason is, you need to see if the power steering control module is offline. If it is, then this is an electrical issue or a module issue.
If not, it could be a mechanical problem but this system uses a mechanical (traditional) system that is controlled by a modern electrical control module. Basically, it can vary the power assist based on speed and driver inputs.
Let us know if you have any codes and we can go from there. Thanks
