Are you focusing in the AF focus area box (pretty small area I've noticed)?
I have the 24-105mm EF lens but I am thinking aobut getting the new 10-18mm EF-S STM lens so I am curious about dual pixel AF support and performance.
I really increased the funcitonality of the new AF by setting button 7 (usually the magnify button) to AF Lock and the that make it much easier to use autofocus AND reframe the picture (so the subject does not always have to be right in the center). That tip came from Phillip Bloom, who has a video on Canon about it: http://www.usa.canon.com/cusa/professional/standard_display/eos_c100_feature_upgrade
