Well - it looks like we're all in the same boat - very expensive bike with a dual sided power meter fitted that's battery housing crumbles/falls apart when it has been in use for a couple of years and the battery is changed - no service replacement offered leaving the only solution to purchase a new crankset at well over $1,000. Shame because the rest of the 4iiii products and service I've used/received have been great - However, this problem needs reported and a suitable resolution/compensation recieved. I also like to be included in any class action suit if taken. BTW I gave 1 star because I couldn't post with 0 :-(
