I had this issue over a year or so ago! After buying a new brewer and it doing the same thing, I was convinced I had bad k cups! After numerous calls with Keurig I inadvertently mentioned that I had good water because I had just put in a water softener and filtration unit! That’s when the Keurig service lady told me that their brewers don’t do well with softener water! Said use the cheap ole Walmart spring water and my exploding k cups should disappear! I thought they were nuts, but I switched to that water and have had no issue since! I even had the brewer outside for trash pick up and brought it back in to try it one last time. I’m still using it! Don’t use water softener water period! Hope this helps someone else!
