I cannot get in to my dealer until 7/16 for this update & inspection.
I scheduled my CVT software update appointment online (Nardy Honda, St. James, NY) It's
for 8/23! I'm not driving much now (laid off from job) and don't have any
long trips planned between now and then.
I was concerned about the CVT tranny when I bought my HRV in March 2016
but I figured it had been used in the Civic for a few years so I figured it was ok.
Not very confident of taking a long trip in my HRV now :-( but I do like the vehicle
a lot, features, fuel economy, ride is fine.
No car is perfect but a tranny replacement on a Honda is troubling. I expected 150,000-200,000
miles of trouble free service (35,000 miles now) I keep up with maintenance on all my cars.
5000 mile oil changes (synthetic) tranny, rear differential fluid at 30,000 miles. Antifreeze 50,000 miles.
Brake fluid flush every 5 years or sooner. Cabin filter, Air filter every 25,000 miles etc...
I've had no issues with the HRV, rides well. Only problem I had was rear rotors rusting up, uneven
pad wear on rear brakes within 25,000 miles. I showed pictures to service manager on one visit for
service and he didn't have any comment (car was out of warranty) I replaced rotors and pads with
PowerStop parts from RockAuto, seem to be ok
So, follow up after software update on 8/23/21.
1. HRV seems slightly more sluggish starting off,
barely noticeable difference.
2. Rubber band effect seems less although I never
thought it was that bad.
3. Even though it's a CVT I've always noticed a "shift"
at around 40 mph. The "shift" seems softer now
4. Fuel economy is down a bit, maybe 3 mpg, but I've only
driven about 100 miles since update, mostly local. I did
have a highway drive yesterday, about 70 miles total and it
seems the mpg is improving.
Final note, all these observations are very subtle and may just
be my imagination

lol
Update took a little over an hour, service department was their
normally busy early morning but they are pretty good.
I will continue to do transmission/rear diff fluid changes every
30,000 miles, Honda fluid is not that expensive and it's easy
enough to do.
Let me know what you guys/gals think.
10/18/21 follow up to my follow up
trans software upgrade done at 35,874 miles. I now have 37,300
and have taken one 500 mile round trip. Fuel economy is back to
normal. I guess it took some driving for the computers to relearn all
parameters. Trans is working well.
