The seal on my 2014 Accord leaked from day 1. I had it replaced under warranty at 33000 miles. Was told it was a faulty seal from when the car was built. They had to drop the cvt and open it, so they replaced the transmission oil when reassembled. No more issues with it again.

Its a mechanical part... Sometimes they fail.

Someone else posted a thread that referenced an official video made for Acura SUVs. They put assembly grease on the transmission splines, which "melts" when the transmission gets hot.

This can be confused with an actual leak, when it isn't. The video says to wipe off the leakage and monitor for a reappearance. If the fluid doesn't reappear, then there isn't an actual leak.

mechanical, it happens that's what warranties are for.

As for other issues, that's what happens when you want cars that do all the driving for you. too much tech, too many things to go wrong.

Anything new in the last couple years sucks. Never a good idea to buy a new vehicle that every aspect is brand new design regardless of manufacturer. This new version CRV is the only hondas to have so many issues.

Honda doesnt make fancy electronics, they normally make drivetrains that last forever but markets have forced Honda to abandon what they do best and leave put the access garbage.

At this point I would call or email Honda Corporate, or whoever is appropriate, detail the car's history of issues, and ask for a warranty extension. I have read some reports on here where other owners have been given extensions. Otherwise I'd guess you likely have a valid lemon law case.

I would be concerned. Yes, mechanical things just fail and that may be all it it. Just a bad seal or installed incorrectly. Nothing more or less.

Or it could be an out-of-round shaft or not a true, aligned shaft. In that case it likely will fail again at some point. If it lasted even as long as 33K mile, I doubt a visual inspection would not detect this. Perhaps an examination of the failed seal might give some clues however.

And the operating environment may have contributed also. I have noticed that Honda requires relatively frequent CVT changes. After the first at 15K, and 30K for subsequent ones, as I recall. Unless, as noted, in the owners manual, if you do frequent mountainous driving, change even more often No details, they just indicates this is servers operating conditions apparently. I would think towing and high speed driving in a hot climate might be an issue also, but they do not state this explicitly.

I think the high heat ai see in my CVT (sometimes 240F) probably indicates this prudent. And yes, I live in a mountainous state and see the temp in the mountains on my Scanguage.

Here's the note on mountain driving or towing which says 25,000 miles.

Thanks, I did not recall if they had a suggestion-it was in March 2017 when I saw this caution. I just made a mental note to be aggressive on the CVT fluid changes. I tend to maintain high cost item like transmission/diff even more aggressive then the manufacturers suggestions I did my 2017 CVT/diff both around 5k. Probably will do the CVT at 20-25k miles regardless.

In fact, I will probably do a trip today with about 4k elevations gain. But it is cold, so it will be interesting to check the CVT temp in 40F's weather.

I have heard some refered to the CVT's hokey puck, but it that a cooler for the CVT. It was never clear to me what it does. The Honda comment about very low speeds would seem to indicate the CVT cooler it not effective at low speeds due to air flow, I assume. If anyone know, thanks for the input.

And I assume very low speed is under 25mph or so. So technically, even in the worst mountain passage, I rarely go below 25mph. Most would be 30+ even in mountain driving on decent roads.

 

[sirwired]

The “hockey puck” is a heat exchanger with the coolant. No air flows over it at all.

 

[Tigris99]

yeap that puck they use is a joke. Been round since early 2000s accords. 99% of the reason some Honda transmissions have a crap life.
