Just got back from out of town, the car being idle and plugged in, in the garage for 4 days. Got in my one month old 85D with 900 miles on it and saw a warning message, something to the effect, "12V battery needs to be replaced soon." Called service and they said it's an advance warning, no worries about driving the car, probably part of a bad batch of batteries. They seem to purchase a lot of those bad batches, don't they? I wonder if and when they will find the true problem with these. First available service appointment is mid-June. They will drive a loaner out to me for the day. Hopefully they are right about it being a (far) advanced warning and I don't get one of those "pull over now" messages on the road.
