Stop/Start seems inconsistent

[crb1701]

Hi All, I just got a new 2021 Crosstrek. I don't mind the stop/start so much (yet), but I don't know why the s/s kicks in sometimes but not other times. This morning I hit four traffic lights. Two of them the s/s engaged, but two of them it did not engage despite the same wait times. Why doesn't it engage all the time?

On he outback, probably same system, If you dont push quite hard the motor does NOT stop. Maybe on the other two you just eased the brake down, try it.
