If the coolant is getting low in the tank than obviously it is leaking somewhere, either internally or externally. If it is internal than there will be white smoke coming out of the exhaust system. If it is external than you will have to give the engine compartment a good look over to see where the leak is coming from. Don't forget to check the transmission fluid, if the tranny cooler has failed than the coolant can internally leak into the transmission.
