Having read this whole thread, I'm struck by the similarities to my problems trying to get Madison and/or Shimano deal with faulty batteries. In the end I went to small claims court and it went to arbitration when the supplying dealer (a big corporation in my case) fought it. I am not allowed to tell you the outcome of that, but I was left satisfied.I have a Santa Cruz Heckler with a Shimano E8000 motor. I really do love the bike, it has taken me places and done things I'd never have seen/done otherwise. It's decent spec and is now 2.5 years old and out of warranty.
Knowing what I know now, I couldn't in good conscience advise anyone to buy a bike with a Shimano motor .
Santa Cruz advertise that they want to get you out riding. They've been great at things in the past and I have other Santa Cruz bikes but when it comes to anything Shimano, they can't do anything to help and you have to contact a Shimano service centre.
Shimano do not service the motors and do not offer parts. Motors are not offered for sale either, you simply can't buy one. The reason is the motors have parameters specific to the bike they're fitted to and UK/EU laws mean these have to be restricted to maintain the max speed/power limits.
As such, the service centres can't change any of the motor configuration, that can only be done by Shimano's UK representative, Madison. Madison can only offer warranty replacements and they can only replace like for like.
I can in theory fit an EP-8 to the bike, the physical mounting is the same and Santa Cruz did ship Hecklers with my frame with an EP-8. I would need a new speed sensor, cable, display and mode switch but those are solvable things. The trouble is I can't obtain a motor anywhere legitimately in the UK, nor change the settings on it if I could.
As far as I can tell, supply of EP-8 motors for warranty replacements is problematic with long delays. Santa Cruz only has motors to fit to new bikes so basically fobs off existing customers with "talk to Shimano, only they can solve this". Talking to Madison, they say "only Santa Cruz could provide an upgrade kit". Given the supply issues, nobody is interested in resolving things. This is really poor for existing customers, particularly when they've used a brand based on their support in the past.
Both sides don't understand the other. Santa Cruz has told me I can get a Shimano service centre to change the motor bearings for example. This simply isn't the case.
I can buy a bearing kit online and then service my existing motor myself, if I feel like taking the chance. There are also places offering that service, the trouble is should anything go wrong, there are no spare parts.
The motor is out of warranty. If a service centre runs tests and determines my motor is failing, Madison might at a push agree to replace the motor out of warranty, at the cost price of a new motor. If I'm going to spend £900+ on a new motor, I'd prefer the EP-8 but that isn't an option. I wouldn't get to keep the old motor, it has to be done by the service centre and I can't repair it, only replace.
It looks like I might be able to obtain an EP-8 motor from elsewhere in the world, obviously that would have no warranty and I could have fun with import duty/taxes. It is possible to use unauthorized software to change the software config. Whilst that wouldn't have any warranty support, would I actually miss out on much given where things are at?
Anyway, I wanted to share the experience and put a plea out there to Shimano and Santa Cruz to sort this experience out, please! As things stand, I really can't recommend them.
In the UK consumer legislation specifies that goods must be fit for purpose and of expected quality. I would think that you have a very strong argument that being unable to repair a 2.5 year old bike that cost you many thousands is "unfit" and therefore falls under consumer protections. Sadly the responsibility for this falls to your supplying dealer, not Madison or Shimano, but I would think you have an excellent case to put to them that they need to put this right or you will take them to small claims court. That's what I ended up having to do to get it sorted.
EDITED as I realised it implied I had taken either Madison or Shimano to court. I had not, I had to challenge the dealer despite it not really being their fault.
