Thanks,Actually, I finally got my v9 2018.46.2 update today, P100D March 2017... and I noticed it was also in Jack mode immediately after updating. I turned off Jack mode and have plugged it into charge, so will see what I come back to... but I never experienced this before the v9 update today. So, it figures that it's a bug in this particular firmware.
This is very helpful anecdotally.
I recommend that you call Tesla to add this as a data point for them to increase their urgency. I would mention that you know you’re not alone with this issue and that technicians are working on it, but that you would like them to look at your VIN as well for additional data.
Just curious was your car set to very high (Smart location tagged?)
I did find out that it doesn’t matter whether it’s plugged in the charger not.
Just needs to sit around for a while. (2hrs+)
