It seems like this has done the trick... so far. After almost a week at the service center, they completely emptied out the tank, refilled it, and made sure that no air was present in the system.

The service manager told me that what probably happened was that when we came to top it off the first time, the car didn't have enough initial time to cool down. The result of this was that the added coolant retained air in the reservoir, which ended up causing the coolant to disappear. I was informed that if anything happens within the next few months, that it will be covered without any problems.
