I am getting this SD card reformatting too. I asked if it was widespread and the tech said no, they have a new program and are testing remote reformatting on my car because it raised a flag in a new alert system. If it is successful I won’t get any kind of alert. If it fails I may get an error message and I will get a call from tech support.
This car had a series of failed updat attempts shortly after delivery. The SD card was implicated but eventually the whole MCU was replaced and a few updates have happened without difficulty—until the last one.
Since upgrading to 2018 .18.3 my car has a doppelgänger. The phone app switches back-and-forth every few seconds between my car with the correct name, the correct location, accurate charging status and another car with open frunk, open trunk, wrong name and wrong location. Tech-support describes this as the server receiving two sets of information from the same VIN. One set is the last data from before the MCU replacement and the other is current. A ghost in the machine which I am hoping can be exorcised with this new reformatting process.
