Hi,
Based on your description, I assume this has electric power steering. The system is composed of several components, a torque sensor, position sensor, electric motor, and a power steering control module (PSCM).
It is hard to diagnose this issue, but I suspect it has to do with either the torque sensor or position sensor. Here is what I suggest. The vehicle has a control module specific to the power steering. Therefore, you can scan that module for diagnostic trouble codes. To do this, I recommend scanning the can-bus system. CAN stands for controller area network. Basically, a few wires connect all the modules/computers together. When you scan the entire can-bus, you are checking for diagnostic trouble codes in all modules and not just for the engine.
Here is a video showing how it is done:

In all honesty, this should identify where the problem is coming from. If this isn't done, it becomes a guessing game.
Let me know what you find or if you have other questions.
Take care,
Joe
