SOURCE: radiator leak
It could aslo be the exausht manifold leak i just last month had to have that fixed. run your car for some time then stop and check underneath see if it is leaking towards back end of engine or if you can hear a hissing sound fron middle top of engine

Sine you are concerned about the warranty timeline, perhaps you should take the car to the dealer and explain the problem. Hopefully the warranty will cover the repair.
The problem won't go away...

Testimonial: "thanks alot.truck is not making a rattling noise.we did check it with a manual gauge.it read about 10 at idol. press. gets better as you incr speed"
Have the computer scanned if you want a quick scan have Auto Zone or the like scan it for free , they also will give you a printout of the problem code, if any, that may be stored in the computer system.
Trans. fluid is only checked on a running in park warm engine, if it is not running the fluid will read too high on the stick showing an overfilled condition, use only recommended fluid, should have the type requirements stamped on the transmision dip stick.
When filling do it slowly and add only half a quart at a time checking the level each time as to not over fill.
The trans. fluid and filter should be changed every 30,000 miles as preventive maintenance proceedures.
Hope this helps, good luck!!

When coolant gets drained and refilled air bubbles are often trapped inside the cooling system. If you imagine pouring a soft drink and you see all the little bubbles sticking to the sides of your glass, you'll get the idea. After driving those bubbles eventually "burp" their way up to the top, and consequently the coolant level drops. Top it up one more time and my guess is you'll be good to go.
