Hate to say it but the OP from that thread also had a CVT and his Canadian dealer ended up replacing the transmission
Seems wild at under 25,000 miles!
At your mileage, I would press for a goodwill replacement from Honda. Your dealer should be an advocate, especially as you have evidently been a good service customer. A Honda reman CVT replacement is around $5k (I know this), but Honda should be willing to cover the parts (2/3) if you pay for the labor.
This would be my approach at this point.. maybe link your thread so corporate can realize how ridiculous the situation is since you changed the fluid twice already!!
