Method printer no consistent extruding

Anyone here using the Method printer? Several years ago, we bought a Method X which has been going gangbusters for the students with very few problems. The department got some free money to buy another printer, this time just enough for a Method, which should be fine just printing PLA. However, right out of the box the printer was failing on both the build (PLA) and support (PVA) extruders, so we returned it for another Method. The second one worked well for about 2 months, then the same problem, although mostly it has been the 1A extruder failing time and again. WTF is going on here? Two bad printers in a row? Is this a known problem with the Method printers? Thanks.
