Did the ICE ever warm up prior to the vehicle being in EV Auto?
I ask because mine will start the ICE while in EV Auto if the ICE had started and warmed up while in EV Later prior to me switching back to EV Auto. I have a ScanGauge and observed the magic threshold to be when the coolant temperature drops to 110F. I think there may be other variables that determine whether it kicks on to rewarm itself though because it doesn't always happen. But, when it does happen the coolant temperature is always 110F. I believe mine will restart the ICE while the transmission is in park.
