Interesting, between me and my local group there are 6 Levo owners with whom I rode at some point in time, 5 of them have never experienced motor problems. One guy even rode gen1 Levo.
The guy whose motor died said that he actually abused it a bit, he wasnt shifting correctly, rode in turbo within limited gear range.
I dont want to say that every faulty motor is a result of bad shifting habits, but I cant stop thinking why in my region Levo seems like pretty reliable bike and at the same time people in internet screams about faulty motors at incredible scale.
My mechanic make motor rebuild for 100$ and reanimate some old Brose motors, he says its easily repairable and almost all parts can be purchased and replaced, despite planetary mechanism I guess . Most cases are simply water corrosion or broken planetary mechanism which is more rare in his experience.
