2011 Toyota Prius Vibration on start

My Prius has about 130,000 miles. It has done this vibration thing about 3 times since I've had it. It does burn a little oil (about 1/2-qt over 3000 miles). No idea what this is. It only happens after the car has been sitting unused for a couple of days, and only when I very first start it up.
