Believe I found the problem and the solution. The issue is a faulty air pump that purges the liquid remaining inside the K-cup at the end of the brew cycle. The repair appears simple but requires removing the shroud that surrounds the Keurig. Here are links to YouTube videos that will help guide you thru the procedure:

Replacement pumps can be found on Amazon, Ebay or AliBaba. From what I can tell, there are two types of pumps. The basic pump is the same but the mounting method is different...one has tabs and the other has a bracket. It is next to impossible to find any parts listings by model so you may have to open open up your brewer to confirm which one is used. My Keurig is a K2.0-400 and uses a CJP37-C12A5. BTW, Keurig customer service was useless. Their solution was to buy another Keurig which they would offer a 20% discount if purchased thru their website. Such a deal!?!?!?
