Mines a 2014, and I have just checked the proposed recall N759 on the online service history and it doesn't mention it for my car.
I've read through most of the 45 pages of this thread, and from what I have gathered, it would appear to be certain VIN numbers between 2013-2018 which could relate to batches of the knuckles.
Speaking as an engineer who has spent 40 years in aerospace/military design its is not a good idea to use a split clamp arrangement where you can sustain vertical and vibration loads, I certainly wouldn't use aluminium (unless using LM series grade cast aluminium) and possibly over torque the clamp, you can see alot of the cracking on the opposite side to the bolt.
Aluminium is more susceptible to fracturing as it does not have the elasticity of steel.
Regardless I reckon either no FEA was done on this part, or an inferior grade of aluminium was used, not uncommon when getting it made in India.
LM series aluminium has good corrosion resistance and is often used where salt air corrosion can be a problem on aerospace parts.

My thinking is that when Tata took over Landrover in 2008, they directed most of their manufacturing to be done in India.
There in lies the problem!

Thanks for the response @goldeneye32 some very interesting thoughts, and I'm sure you are correct... 2015 SDV8 L405 Autobiography in Santorini Black

I recently bought (3 weeks ago) a 2016 L405 5.0 SC and found out about the recall about a week ago as it popped up in my Carfax Car Care app. Went out the other night to inspect the knuckles as my car falls into the VIN range and production dates and low and behold...Driver side cracked. Call closest dealer (4 hours away) and they couldnt tell me much other than bring it in for a diagnostic check. I agreed and asked about what we do after that and they didnt know. asked if they had a time frame for parts, didnt know, asked about continued driving again they didnt know.

so called JLR USA and they recommended calling another dealer to work with, so called next closest dealer and its 5 hours away other direction and they asked for VIN, pics, contact info and such.
Gal talked with service manager and then contacted regional person and are working on a plan to get me fixed up.

I know what dealer I will not goto again...I bought my first Range rover from them back in 2001, a 1996 4.0 SE. They didnt even have me in the database anymore.

Another one through the workshop today

17MY, 84k miles, brought in for a routine service. She had just driven 55 miles down the motorway this morning on her way to us
