Data point: Received update on Thursday and turned on pre-conditioning that night. Then yesterday (Saturday, around 2pm) car's climate system came on while car was in garage and wouldn't turn-off (no rhyme or reason relative to my work schedule). Tried locking/unlocking cycles, plugging in and disconnecting plug and even turning off pre-conditioning, but climate remained on (I purposely did not turn off climate on the main screen in order to try to understand what was going on). Ultimately what seemed to work was to keep pre-conditioning turned off, put car in Drive momentarily and then back in park, exiting car and then locking it. Seems turning off pre-conditioning alone didn't do anything, but cycling car to full on and off again was enough.
Looks like the algorithms need a bit more refinement, but expect that will happen as the feature matures (i.e. more data comes in).
