Coffee pot only brewing 2 cups at a time.

My husband and i purchased this coffee pot approx a month and a half ago. And we were loving it, not only brewing coffee, but ice tea as well. No plastic taste or smell that I can recall. Within the last week, the coffee pot has decided that it will only brew to cups a coffee or tea at a time. And we have to shut it off and turn it back on again for it to brew another 2 cups and turn it off again. We have to continue this process until all 12 cups have brewd. A real pain in the ****!!! We have cleaned the coffee pot, reset, unplugged and still to no evail...only 2 cups. What is the problem? Or do I just need to return it.
