about time, although they've been good about replacing them

Save some people a click:
Remedy: Consumers should immediately stop using the cranksets manufactured before July 1, 2019, and contact an authorized Shimano dealer to schedule a free crankset inspection. Only consumers whose cranksets show signs of bonding separation or delamination during the inspection will be provided a free replacement crankset and installation. |
I feel like they are going to have to expand that recall.
It's hard to generalize, and I'm sure there are exceptions, but it seems like this problem is much more likely to affect cranks that are ridden a lot in the rain. I imagine that shops in certain areas of the world are going to find a lot of cracked cranks. I have to admit that I'm a bit less likely to buy a shimano crank because of this problem. |
The remedy is not great for the riders. Some people will bring in their bike, mechanic says there’s nothing wrong with the cranks, and off they go. But that crank still has a failure risk. Riders should be keeping an eye on them regularly to check for separation/de-bonding.

I gave up completely on Shimano after the 12 speed XT/XTR shifter debacle and the (still ongoing) defects in their Servowave mountain bike brakes.
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. |
I guess the good news is that it should make getting these replaced even easier when they fail. The bad news is, to avoid failure, you have to catch them at the point after they've started to fail and before they completely fail.
Does anyone know if these failures are only on the drive side, or could they affect non-drive side too? Asking for someone with a few left side Stages power meters. |

This. Even if your crank passes their visual "inspection", would you feel comfortable using it? I wouldn't. That reported number of failures is way too high. |
From an engineering standpoint, I say this is a completely bumbled recall.
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. |
Only 'LG' cranks??
None of mine are LG, that's good.. right? OOps, no. The affected models are pre-July 2019 production and have the following two letter production code on backside of the crank arm where the pedals are attached: KF, KG, KH, KI, KJ, KK, KL, LA, LB, LC, LD, LE, LF, LG, LH, LI, LJ, LK, LL, MA, MB, MC, MD, ME, MF, MG, MH, MI, MJ, MK, ML, NA, NB, NC, ND, NE, NF, NG, NH, NI, NJ, NK, NL, OA, OB, OC, OD, OE, OF, OG, OH, OI, OJ, OK, OL, PA, PB, PC, PD, PE, PF, PG, PH, PI, PJ, PK, PL, QA, QB, QC, QD, QE, QF, QG, QH, QI, QJ, QK, QL, RA, RB, RC, RD, RE, and RF. |
