As good a place as any to add my recent experience.
Add me to the list. 1600 mile MTS 1200S Touring. Bought as leftover new stock last year., so under factory warranty. I tried to persuade them to update the sensor/sender before purchase, but noooo, it hadda fail first. So, here we are. Part on order.
Two thoughts: BMW isn't immune. Google BMW motorcycle fuel level strip. Big issue with some GS-es. The fuel gauge on early F800s is so bad they refer to it as the "guess" gauge. The second thought is "why motorcycles?" If (insert your choice of car maker here) had this kind of pervasive problems with the fuel level sensor, the NTSB would be involved, and it would've made 20/20 or Dateline by now.
