Does that mean that the problem extends to other Shimano cranks?
E.g., older 10 speed cranks or cranks newer than 2020?
We donāt know yet, and its not like she is a watt monster. But we do ride on bad roads.
The 2021 Trek is going to be inspected when she picks up her Colnago.
I took my cranks to the shop and the tech pronounced them good to go after about 5 minutes of inspection. He didnāt record any information though and Iām not sure if the shops are supposed to report pass/fails to Shimano. The whole process was very casual.
Which is why this will likely continue to be a major issue for Shimanoā¦.and I suspect will eventually force them into recalling all cranks.
As noted multiple times, the inspection process does not mean the cranks wonāt fail at some point in the future, not does it mean that they have really been thoroughly checked (as the process was ācasualā).
This, to me, leaves shops liable (āYou told me they were fine!ā) as well as Shimano.
There are also mounting issues with the nature of the recall in Europe as it may not meet requirements for redress (see the latest Geel Warning podcast where they discuss it).

I agree with all of your points. Maybe Shimano will be ordered in the US to replace all the affected cranks regardless of condition. In the meantime Iāll continue to keep an eye on my cranks and keep riding.

5 min? Did he take off your chainrings and inspect? That what hes supposed to do. Also, weird as shops are supposed to get paid for crank inspections. I assume they need to fill out paperwork in order to get the money.
Mine told me they took photos and submitted them to Shimano, despite them supposedly being fine. I assume thatās to prove theyād done an inspection, to claim the payment.
He did not take the chainrings off which I thought was interesting.
I would go to another shop and get them inspected againā¦sounds like they did not properly inspect them.

Iāve been inspecting cranks for my customers and had this one today listed in the recall batch.
I almost missed the problem with this crank. The issue isnāt visible, at least to my ageing eye, nor can it be felt either. I only spotted the problem because after washing the crank it was wet in one area that when dried, became wet again. Upon squeezing the section of joint tiny water droplets came out. I hope that the video is useful.

Great spot 
Iāve not had my crank inspected yetā¦ I really should.
Having found this one, Iād definitely get it checked out as theyāll only get worse. This was a light female rider, so not big watts and with a well-looked-after bike.
The other reason to do it is that it brings in workshop business for your LBS or independent mechanic in what can be a quieter time of the year. Particularly this year!
Are you able to share your thoughts on how wide-spread the issue is?
Roughly what percentage of cranks you have looked at seem defective and is there a certain model of crank that is worse than the others?
My inspected numbers are too low to give a valid opinion. If I find more Iāll drop it in here and update any patterns that emerge.

Now that Shimano has been hit by a massive ransomware attack, maybe weāll find out what they knew and when. Theyāll probably pay the ransom, though.
Also, the ransom deadline has passed. So either Shimano payed up, negotiated a bit more time, or juicy details should be floating around somewhere.
Just an Update - Shimano Warrantied my crankset.
The procedure was painless and took a total of 10-days (this included shipping my cranks to them for inspection).

No word on the hacking outcome. Best I could find was @gpl Twitter.

Just got a web link for my PM rebate form. Says it will take 6-8 weeks for processing, and then they send me a check.

And to follow up/further fill in the timeline, shimano sent me an email saying i will receive a check for my PM in 10-14 days.
