Steering wheel turning on its own

You do have electric power steering with this vehicle, which means steering assist and control as provided via a Power Steering Control Module (PSCM) utilizing a power steering motor, a steering wheel position sensor, a steering shaft torque sensor and related components. As such, you'll need to have professional testing performed by someone that has a suitable diagnostic tool able to interface with the control module and determine what is happening while you are experiencing your symptom. I would expect that there is some kind of concern with sensor / wiring that is causing the control module to control the steering in the direction you are saying it is turning. But there are multiple strategies going on here to prevent safety related issues - so you'll have to perform proper needed testing. It must be done by someone with technical resources (manuals / wiring diagrams) and an actual diagnostic tool - not some kind of "code reader" -- that will not do you any good. Good luck.

Did you ever figure it out? Mine does the same thing. But not consistently enough for someone to witness it. Some say steering column assembly? What was the fix? Thank you!
