VY II calais electrical issue

[Aryashahin]

hi all,
an unusual thing happened last week in the morning while driving to work ,my Calais installed, and i couldn't restart, called RACQ and the good man jump started my car, thinking it might have been a battery issue. after testing the car and taking it to local mechanic they find nothing wrong.

Few days ago i realized auto shifter light are gone, sunroof buttons mix up every time start engine, and last night the ABS beep alert was activated on my screen to top that up the electric seats rest and wind down all the way down and the engine has trouble starting, it almost feels like its out of battery [ battery tested and all good ]. can hear the fuel pump and started working fine.
Does any one have any ideas what the hell is wrong on? should i rest the computer !!

Is it possible that something is draining the battery while it is parked?

sounds like battery or alternator, there was a post on here a while ago about random alarms and warning chimes and ghostly moving seats. My car has done it twice now, both times before the battery was about to go and failed 2 days later.
