In my opinion, yes they still need to do some work on the calibration.
I can only imagine that the poor souls who get Auto Start/Stop in the 2013 X3 will suffer even more... I can see offering this as an option, or even allowing one to activate it, but requring one to deactivate it after every start on a supposedly driver oriented vehicle is crazy. I am SOOOOOO glad we got a 2012. We wouldn't have purchased the X3 with that feature. Even KIA allows you to buy auto start/stop or not buy it in an option package. BMW likes to make money on every other option, why not charge for this1?
