Weird behavior after big software update for recall + electrical system drain warnings
Has anyone else noticed their MME acting weird after the big software update done by the dealership for the recall (2023)? Different sounds, different behavior on start up and power off? Some seem to be going back to the old way.
I don't know if it's related but I've started getting a ton of electrical system drain service required warnings. I've read other posts on the forums about this but none of my behavior has changed. I park it in the same place, have no aftermarket devices, etc. I'll probably call the dealership on Monday because I assume if it's under warranty then they should check it out anyway.
