Just quickly scanning this thread, I don't think any of the CVT transmissions that failed ever had their fluid or filters changed.
Lack of maintenance is a major factor in any transmission failure. It's in the owner's manual.
Do not rely on the dealer or the maintenance minder on the dash.
The problem is that it isn't "in the manual" at least not the US Owners manual. It gives no timeframe for changing the transmission fluid in normal driving conditions. It tells you to follow the maintenance minder and have the dealer check it. I did both of those things and my transmission still died. I also spoke to several people with failed 2016 CVTs that had changed the fluid at 30k and 60k miles. Some transmissions have even failed before 30k miles. The only thing the manual says about a timeframe for changing the fluid is:
"Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. This requires transmission fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the transmission fluid changed every 25,000 miles (40,000 km). "
I live in Florida. My HRV has never been driven in the mountains at low vehicle speeds. Many cars do not require transmission fluid changes until 90k+ miles, so it did not seem unusual that the maintenance minder had not told me to do it yet and the dealer never suggested it.
Anyway, I think the proof that there is a latent defect in the transmission is this:
I heard back from Honda today and they have agreed to cover 80% of the parts and labor for a new transmission even though I was 13k miles out of the powertrain warranty.
Obviously I am thrilled, but I think this is bad sign for the longevity of other 2016 CVTs. If I were an owner of a 2016 CVT that hadn't failed yet, I would exclusively get the fluid changes done at Honda dealers and immediately take the car in anytime there is even the slightest vibration, stutter, or noise from the transmission. I am convinced that a huge portion of the 2016 CVTs will not make it to 100k miles.
