It depends on where the expression is uttered. The construction "Me choca que..." in Northern Mexico is usually uttered out of anger. I've never heard it used to mean "surprised", though I would understand, as 'chocar' comes from 'to shock'.
This sentence is originally from public domain material released by the US military (?), and the expressions seem to be from various geographical locations.
