Interesting report. We actually make ebikes in Fukuoka Japan utilising only E8000 motors. One of our tests bikes has over 26,000kms. We haven't had any problems to date with any of the Shimano motors.
 
i have 3700 miles on my e8000 commencal meta. the battery to bike connector of the mt e8010 cracked and shimano offers no spare parts for repair of an otherwise ok battery. so now i own 2 other batts. ive replaced the speed sensor once and the mode selector on the left perch twice. the motor itself seems fine. the lack of spare parts for a durable goods ....get out of here Shimano...man up behind your products. could you imagine a terminal on a car battery failing in 2 years and they tell you to shove it...well maybe but they are a world class outfit...or so they claim. i understand the polini motor is completely rebuildable..and they will send out parts.that is the way.
 
Part of your actual battery cracked?
If it was due to a manufacturing defect and within 2 years of purchase your countries Shimano distributor would have replaced it.
If it was broken from accidental damage. That would not be covered by any manufacturers Ebike batteries' warranty.
 
I work in data visualisation and they have some very creative and impressively bad charts in that report. Clearly designed to look pretty rather than allow a decent comparison of values. They break just about all of the guidelines for creating usable charts. Statista should know better!
