If you are losing this amount of fuel I would be very concerned. If it is still under warranty I would have them repair it. Bring the car to them full and have them let it sit in their shop overnight. Any leaks should be apparent to them.

It also could be a bad fuel level sensor or fuel gauge that reads higher one time and lower the next. If you were leaking fuel, you would be able to smell it when you approached the car.
