Got mine back from SF SC with upgrade. Seems to have fixed issues that many here have posted about. With the caveat that it has been only two days, no Brake or Washer Fluid warning and Vampire Drain goes away. Mine used to lose about 0.3 mile per hour when parked overnight (in garage in SF with no monitoring apps). Now zero loss overnight !! Also SC said they "updated the Battery management system bootloader" so maybe that also helped with drain.
