My Formentor was updated to version 1898 yesterday and has worked faultlessly since I picked it up this afternoon. I have only done 3 trips and 60 miles but before this update I would get the SOS error every time I drove it and would quite often get the car to change users randomly.
 
Glad I found this because I thought maybe I was going crazy because this morning my passenger side wing mirror randomly readjusted itself and was pointing upwards so I couldn't see anything other than the sky but had been ok leaving home. Noticed it while in traffic.
