Mark, I had the same issue with the Batteries. I'm going to guess that ours were installed by the dealer! We had a set of locally produced 27 series Lead acid batteries that were flipping codes all the time. Merc Tech came in and did a "White Glove" service and gave us coupons for $125.00 off for new Batteries. We now have 4 AGM 31 series batteries and that fixed the Axius problem... but the batteries were another issue!
