Vector 3 falling apart - Second time

Has anyone else had an issue with the pedal body shifting off the axle?
This is now the second time its happened, both times about 9 months apart.

I can see no reason for it, only happens on one side.
Im not heavy on pedals otherwise, 80kg rider, no crazy sprint (1200-1300w max)

WHY does it keep happening Garmin and what can be done to sort it out??
