Nothing leaking on the floor im assuming? Have you check the oil to see if you have any antifreeze in you engine? Is the car blowing white smoke from the tailpipe? Is so you could have a blown head gasket....if not then have you checked you raditor cap, you could be boiling and its escaping from the cap, is your overflo reservoir vent cap clogged. Is the fan running when the car comes up to temperature? Have you checked the water pump, also its possible the raditor could be clooged, you might have to flush the system...

First ... get this documented at dealership incase there is a service bulletin. Your car is only 3 years old and unless the mileage is very high .. you should have warranty protection. The above answer is the second thing to do. If you are adding anti- freeze and there is no visible leak then the liquid is going somewhere and that's probably into the oil or combustion chamber ... either way you are looking at serious/fatal engine damage and the exhaust gasses are coating your catalytic converter

Tom is correct. Your Cruze has a 5 year or 100,000 mile powertrain (engine and transmission) warranty. The whole car is covered for 3 years or 36,000 miles. So depending on when it was originally purchased you may still be covered by that part of the warranty as well. Definitely take it back to your local Chevy Dealer. HTH. -Jim
