So my salesman called to "check up" and make sure I liked the car and I mentioned this problem to him. I'm going to take it in to the dealership on Monday. This weekend I'll do some extensive highway driving to make sure I can replicate it when I go for a drive with the technician.
The annoying thing about this problem is that it's not constant. My worry is that I'll go for a drive with the technician and it won't occur.
