Good question. To which neither I nor the main dealer could provide an answer. I suppose it must have something to do with the moulding process that created an inherent weak spot.  Any moulding engineers out there ?

Do the bearing the pulleys ran on turn?? (I assume they are ball bearing'd 'bearings' - rather than a plain bearing type).

My guess would be that the most likely thing to fail is the the tensioner. If this failed or slackened off too much it might have caused both pulleys to slip... perhaps overheating and breaking\cracking under the extra heat???

The bearing ran freely not a hint of friction and the tensioner was rock solid absolutely no movement. So I'm afraid neither of those arguments would account for the failure.
I looks to me to be a straight forward case of moulding failure. The fact that it sheared off exactly in half would support that.

Another couple of pics....
