My car listed above Premier model has electric assist power steering. A couple of days ago the steering wheel started rapidly turning a little bit from side to side. There was also a strange noise coming from underneath the car. It does not do it all of the time and it varies a little in severity as well. What could it be?

Good afternoon.

It sounds like you have a control module issue with the steering.
If you have a scan tool, you can monitor the system and see if the wheel is being commanded to turn. there are a couple of sensors that need to be checked.
