-30F yesterday morning warmed up to -15F and -25F this morning. I am now just trying to not have to mess with the 12V any more by bugging it. So this was yesterday.
Need it fixed because as it has shown me it can just drain the 12V which leaves you stranded at any time. 12 V dies 3 times in less than a year. It completely killed one 12 V then drained the new one. Not typical or right I think and needs to be fixed.
Jan. 8 12V drained after a new 12V installed.

Does not like to sit for any extended time, plugged in and cold on this one. I will bug it for now and see if it helps. Keep bugging service.
Doing the same thing as last February noted in TSB 21-2091 as software fixed. Maybe just warmed up last year here by the time I got it back and therefore I did not see it again until this winter when it got cold again? Only when plugged in and cold so far (both 120 and 240) never a problem when unplugged or the summer. Can't test any more this winter as I have a failed. Just guessing I won't hear it is fixed until it is warmer again. Now testing if I can bug it and the 12V does not die thinking maybe the car can do it for itself some day? Waking it up from its deep sleep or whatever it does initiates power being taken from the charger? 10 hours of it yesterday will see today started at 9 am and still drawing when typing?
- Set a departure schedule for 10 am. Started for departure schedule about 1.5 hours early and ran thru.
- At noon I went to check 12V. Lazy so used a 12V outlet reader.
- Plug into console and nothing.
- Started and read 15 V (was charging when turn on good)
- Turned it off thinking I would see true voltage but car started to draw power from the 240V L2 charger after turn on and continued at 15V when off (door opened). Works for me not running at all so left it.
- It never stopped and drew power all day yesterday. The charger and car port were still flashing at 10 PM last night. Stopped monitoring at 10 PM so at least 10 hours it drew power.
- This morning it is not?
- Go out and check while off this morning the 12V SOC 90% at 11.7 V.
- Start it 15V and it starts drawing power again from charger, continues when off. We will see how long it draws today?
