Uh oh! Just shut down on me again today less than a week after problem was thought to have been solved.
Towed to dealer again. This time I got propulsion warning and then when trying to "start" it again, showed service stabiitrak and service brake assist warnings.
At one point showed battery full charge with "0" range.
I will post as I get more info.
Any ideas?
Below is write up from first propulsion reduced shutdown a week or so ago.
edit/note, they removed new battery from write-up, they only charged up and tested current one.

From first glance, seems service dept replacing the EVSE charging port didn't correct the issue...

Should we lay bets on whether the 12V battery is low again? 2012 is probably due for a replacement AGM

Yep, I think so too. Hope it's that simple a fix this time. Got a Silverado for loaner. Won't even attempt getting that in my garage!

Not that water intrusion is a GOOD thing, mind. It just hadn't caused THIS problem... :)

Reading the service report, they only charged the 12V battery, when it should have been replaced ...and guess what, the battery has died again ...

Update...
Dealer called today and said there is a bad cell in traction battery. He was waiting on a call back from GM to find out if they are replacing that section or the entire battery which is what the tech said he would prefer.
Oh well, at least this won't cost me anything except the lack of my car for a while(and gas)! I may swap out that 12volt too when I get it back just because I'm not sure how long it's been in there.

"Update"...dealer says it's "direct ship from manufacturer" part. Can't really give me certain date they'll get it.
I think another member had to wait on his, too.
