Perhaps there is more than one park assist system? But the one I have, only has sensors in the rear bumper, if does nothing to warn of obstacles in the front.
I don't know, but it makes sense if the system fails its self-test it will disable itself. So, likely that is what you're seeing, the system intermittently passing or failing its self-test.
People have posted disconnecting the wires to the sensors and cleaning them with electrical cleaner and then using dielectric grease to put them together has solved their problems. As well, just cleaning the surfaces of the sensors in the bumpers.
The European Commanders have sensors in the front bumper as well as the rear bumper.
