I couldn't find anything with a search, so here goes... A few days ago I got the "12V battery needs service; replace 12V battery soon" message (2014 P85+). I have a service appointment for replacement in 2 weeks. After the message occurred, I noticed I can lo longer summon/autopark. I have made no changes to any of the settings, nor had an update recently. If I try to summon from the fob by holding the center button, nothing happens. Hazards never start to flash. If I try to autopark with a quick double tap on park, the car prompts me for the direction on the main touchscreen, but when I exit the car, it just sits there with the flashers going. It never moves. I only confirmed the connection by trying to summon with the phone app. In that case, I get a dialog on the phone app that says "Error - Summon failed. There was an issue with the 12V battery." Anyone know if this is a bug, or functioning as designed? If it's not a bug, the car should not prompt me for a direction when autoparking in case #2, it should pop up a message like "Autopark not available - 12V battery problem." And it should probably pop up some message explaining why summon with the fob failed the next time I get in the car, so I don't think I was standing there like an idiot holding the wrong button or something... Along the same lines, is there some way to acknowledge and get rid of the annoying "12V battery needs service" message? I get it. The battery is going bad. I have an appointment scheduled. Stop nagging me about it. I put a 12V jump starter in the car, but it just occurred to me that was probably pointless - if the 12V battery fails completely, I probably can't get into the car to get the jump starter.
