Shimano Crankset Recall

[Nessism]

I've got an affected crank, but my use of said crank is low mileage, so I won't be bringing it in. I'll monitor it myself.

I assume, that Shimano will take care of customers with busted cranks for a number of years...but how long specifically? 10 years? Are there legal constraints on things like this?

Reading through this thread and learning that a persistent creaking could indicate a crankset in need of replacement makes me wonder of my creaky GRX Hollowtech crankset will be recalled.

My understanding is that at this time, this safety program is open ended.

No end date.

Do ya suppose shimano will actually 'train' those 'authorized shimano dealers' to know what they are looking for?

Maybe...BUT a LOT of shops sell shimano stuff, not all are 'authorized shimano dealers'..

'maybe'

I do not understand the consistent pattern Shimano has of simply denying serious issues and fixing them quietly without remedy, recourse, or notice to the public. This crankset issue has been notorious for many years and it is hazardous. It should not take four years for them to come clean.

shimano is really BIG..and they, along with other 'big' companies, will take the path of least and quietest resistance. Plus the least expensive. This is going to be expensive for shimano...

If a product has a known failure mode and requires either inspection or replacement, you can't just set a one time inspection point and bless the thing for the rest of it's life.

Agree..what shimano SHOULD do is just replace all of them..not this 'inspect'(by whom?) and pat on the butt. It 'may' look great today but may fail next week.

Shimano is training dealers as to how to inspect for the defect.

I know someone who went through the training yesterday.

The cranks must be inspected by one of the Shimano trained dealers to be replaced under this recall

I suspect I'd become a Campy and SRAM shop.

BUT, I suspect that crank has to travel to shimano-land in Irvine before they replace, unless it's REALLY obvious, like cracked. AND if the brainiacs in Irvine deem it OK, it'll come back..I suspect.
shimano isn't going to just replace and throw away at the LBS level.

According to this post above, not only is there an initial inspection at the LBS, but Shimano seemingly has to also agree that the crank needed replacement once they receive it back. Only then will they ship a replacement. It also reads that the LBS may be out the shipping expense back to Shimano if Shimano doesn't agree it was an eligible warranty crank.

'Authorized shimano dealers' are supposed to do the 'inspection'.

As I said above...a one time inspection that passes isn't any guarantee it won't fail in the future. A 'proper' recall is to identify the suspect cranks and replace them all..period..but 760,000 or something cranks?? Gonna get pricey.

$50 per? that's still $38million...

OP

That is not correct

Only trained dealers can do the inspection

As for shipping costs and needing to send it back before it can be replaced, I will ask those questions

Aren't there (as mentioned by Bikincris) 4 instruction videos that covered this somewhere within? Anyway that we can all watch these?

Doesn't that number only include North America or did I skim that wrong?

[Bruce K]

Answers I just got

1- yes, cranks have to go back to Shimano - too many variations between arm length, model, power meter, etc

2- no cost to consumer or shop for shipping either direction

3- labor credit to shop for work performed and credit to consumer for power meter replacement

Clarification

If, in the unlikely event that Shimano disagrees, the crank would be returned for reinstallation on the bike. All at no cost to the consumer or the shop

Given the complexity of this it would be nice if they published some information on exactly what an owner can look for before going to the hassle of a shop. I have three Dura Ace 9000 cranks in my fleet.
