Shimano EP8rs fail Rate ?

[urastus]

I've got a friend who bricked his rise doing a software update via the app.
dealer has had it 2 weeks now (motor has been sent off) but he is still without the bike.

That is a potential problem with any OTA updates. I'd much rather do an update via a downloaded file (post checksum). That rules out quite a few potential update issues in one hit.

I have two riding buddies with the standard EP8 motors that have had torque sensor failures that Shimano had to replace the motors under warranty. I'm seeing more motor issues with the EP8 compared to the E8000.

EP8 or EP8RS ? im assuming you are the 1 vote on YES ?

The Etube update is not strictly an OTA. The files are already on the phone when the app tells you there is an update available. There are 2 files involved "DUE800 D4.1.8 and DUE800 M4.1.8" for the latest update. These sit in a directory on the phone under Documents/E-Tube/FW/. You can safely switch your phone to airplane mode when doing the update because no network connection is needed only bluetooth. I have always done this to ensure that no text or phone calls can interrupt the update.

that is good practise but does not alter the fact it is OTA using the blutooth connection.........and that type of connection is always subject to interference. Personally I would not use blutooth for a file transfer!!

It is a bit better than previous though - it knocks out the potential of trouble with updating from the internet via wireless in real time. A cable connection to the bike would be nice too, of course; especially considering what is at stake.

Three rise's in our family. Zero issues with all 3 motors
2021 EP8rs 3005 miles
2022 EP8rs 2650 miles
2024 EP6RS 375 Miles

So both of the motors on our original Rise's were eventually replaced. One due to a cracked axle (the issue with the e13 cranks fitted at factory), the other had the torque input sensor fail.

Ultimately the failure rate of all e bike motors is 100% - they're all going to have issues at some point. Shimano aren't repairable but seem to have a general policy of discounts on replacement motors up out of warranty (maybe up to 5 years age). At that rate it looks like the "annual cost" of a motor is about £180.

Given that a set of decent tyres at rrp is over £100 that doesn't seem unreasonable.

This is 100% true. All my ebikes motors have been replaced or repaired sooner or later (4 ebikes).
