I suspect this is something in the power steering system. I attached a bit of information on this because it is not the conventional system. It is similar components but they are controlled electronically.
No matter what it is, I would not take it anywhere but back to CarMax. They have a minimum of a 30 day warranty so I would make sure they fix it for you.
Here is a guide on the common causes of these types of noises but again, I am not sure this will cover what this is doing. The fact that it is only in one direction points me to the steering system. It could just be something rubbing but again no matter what it is I would make sure they take care of it for you.
Let me know if you have questions or if you are outside their warranty, we can dig deeper. If it is covered, let us know what it was. Thanks
