Isn't your car still under warranty? If you can reproduce the problem consistently, I wouldn't mess with anything and just bring it in to the dealership for them to figure it out. This does a couple of things. One if they may have a tech which has enough experience to quickly figure out what is causing the problem and fix it at zero cost to you. Second, if the problem isn't found, you've documented it as a problem in the service history of the car. So if it keeps happening or gets worse, you have a complaint history; especially if this continues into the warranty being expired.
