And realistically, unless the dealership tore it apart and found the culprit (very highly unlikely), we will never really know what is going on in these transmissions, as Honda does not tell us. All we can really do is track failures like this thread does.
Current overall numbers:
2017 - 29 failures, avg mileage 60.1k, avg time to failure 3.55yrs (min 12000, max 150000)
2018 - 16 failures, avg mileage 57.5k, avg time to failure 3.06yrs (min 7200, max 121000
2019 - 7 failures, avg mileage 36.6k, avg time to failure 1.57yrs (min 9900, max 89000)
Avg time to failure is simply the year is was reported minus the model year. I know that is a crude estimate. Again, the one thing that seems to be a common denominator is I am pretty sure we only have seen this happen to AWD models. At least when I compiled all of the data, what I could confirm was every model was AWD. I know FWD comprises a much smaller percentage, but I don't think we have seen a single one with a failed trans.
