Its an interesting discussion to me, does anyone know if it only affects a particular date range, or has a particular cause, or just a random fault? I guess that's why you are looking for a
TSB.
Frightens me a little, as I have disconnected the battery on my Jan 2016 SZII for up to 16 weeks while I was away overseas, and several shorter periods, just to save the battery going flat. It has always reconnected perfectly, no problems.
Any more info is appreciated.
Cheers.
