I will check next time I charge.. When my battery got super hot about a week ago when I had the car on and cooling didn't kick in.. Car was on with the AC being off..A question to ask here is what happens when you turn the car on after the battery cooling process starts? Does it stop or continue?
Certainly something that @stageshoot can give the dealer for the investigation if he can replicate this behaviour. Sounds like it could a programming bug now.
