Lots going on here with the HRV CVT and these TSB's.
1st up, I would say to wait a few months before running to the Honda dealer to get this done.
There is a firmware update to the ECM and while I'm sure Honda has done analysis, testing and piloting, you never want to be the 1st to get any kind of firmware/software update to any device including a vehicle.
Don't ever be the 1st to update your Android, iOS, Chrome or Windows, etc.
The TSB CVT debris test is kinda suspect IMO. Small debris, powdered metal, etc, will never get a magnet to stay attached to the bottom of the aluminum CVT pan.
This check will only determine if large ferrous metal chunks are in the CVT pan.
My thoughts are that they are only checking for pieces of a failed CVT belt.
If your CVT is now due for an fluid change, over 20000miles/30000km, I would get it changed now and then get the TSB's done in a few months.
It's now clear that changing the CVT fluid excessively will not really prevent CVT trans failures.
On the one hand, it's great than Honda has extended the warranty on the CVT.
On the other hand, if your 2016 HRV has an in-service date of mid 2015 or so, this will expire in just over a year from now.
The CVT TSB's have only been out for a few weeks, history will show how this goes.
I have a feeling that the ECM firmware update will derate the engine (reduce engine power) during hard acceleration/load on the CVT.
This may make the sluggish HRV feel even more sluggish, but will prolong CVT transmission life.
