They want 760,000 people to immediately stop riding their bicycles, bring them to a LBS for inspection, and then will only replace ones they find to have signs of delamination.
Yeah, good luck with that.
Mine is on my dedicated Zwift trainer bike. I'll roll the dice. My road bike is Sram.

If you are in North America and believe you have an affected crank, you are advised to immediately stop using it and contact a Shimano dealer or an authorised inspection centre (essentially any store that is familiar with Shimano components and has passed Shimano's maintenance course). The dealer will then perform an inspection, and where signs of delamination or separation are found, a free replacement will be issued.
edit: statement from Shimano says they expect only 1% or less of cranks to need to be replaced.

Yeah, they had major issues even before this recall. They are shallow and not a 1-piece. Some of them are ungluing.
It's a nice thing for the owners that are close to needing to replace them!
Still a lot better than SRAM though

Lots of variables in that design/production process. Doesn't take much to come out with a flaw. I don't know that the problem will go away.

Once a manufacturer offers a recall like this, does it go on indefinitely, or is there a set window to seek replacement?
Both my road bikes have 9000 cranks, which I really like. I imagine they will pass inspection. They look good to me. But it doesn't exactly inspire a ton of confidence during the next field sprint.
If I start seeing the crank separate three years from now, will they replace them then?
I'm also wondering how Frankenstein-y the replacement 11-speed 9100 chain rings are going to look on the 12-speed 9200 crank arms. Anyone have both 9100 and 9200 cranks? Poring over the photos online, it looks like there might be some difference in finish and flow of the lines.

Has anyone on here had one of these cranks fail?
I'm wondering if there is much warning.
Maybe they start to separate before they actually snap altogether?

mine did start to visibly separate as well. it wasn't catastrophic for me, but I imagine it could be if you like didn't notice

I think I kept the parts, so looks like I will get a replacement as they didn't warranty the initial failure.

It is! I wonder what gives Shimano the confidence that the ones manufactured since 2019 and the new 12-speed Ultegra and Dura-Ace cranks are not similarly affected? Are they not also HollowCrank bonded crank arms?
It should; I use Shimano 10-speed rings (105 FC-5750 big ring and Ultegra FC-6700 small ring) with my otherwise 11-speed Shimano drivetrain.

Sounds somewhat similar to the Ford Explorer/Firestone fiasco BITD. Shimano doesn't want to take any blame. "Nothing to see here. Move along."
