the freezing/locking out thing, i have no idea about...
the other issue, they don't let you configure anything that you can't order. willys, hard rocks, polar editions... most of those can't be ordered in canada, they are allocation only. (already built and only can get through a dealer rep)
they don't want you going online and building a willys with hard top, upgraded stereo and heated seats only to discover that it is not possible... they are all equipped the same way.
they start with a sport, then add the willys package. this year, they all have
the 6.5" touchscreen radio (no nav)
dual tops
a/c
trailer tow
they did make auto's and standards... so there is that choice, as well as 2 or 4 door and a few colour options.
there might have been one or two they did differently, but the 40 or so i saw on the list for southern ontario/eastern business center just had that.
