My 2018 CVT transmission has seemed sloppy since new with repeatable oscillating rpm on the highway at steady state throttle around 2700-3000 rpm. The oscillation was most annoying when we were on any long trips where the issue would be exposed most frequently. In the event it may help others, today, when in for an oil change at my local dealer, the tech reprogrammed the main computer, which included an software update for the transmission (there was something for the AWD too). This was not available when I had it in for the issue in the past. Upon leaving the dealer, the transmission operation was immediately notably different, with a more stepped, gear shifting type operation. I drove it on the highway for about a half hour and the oscillating issue seems much less pronounced. Marketing information released by Honda on the 2019 HR-V's mentioned a change in transmission performance relative to the 2018's. My dealer parts guy looked things up and said the transmission assy part numbers are the same between 2018 and 2019, so the difference mentioned must have occurred in the computer mapping. Honda engineers probably now provided the 2019 change for the earlier models. Time will tell, but so far I'm surprised at the difference.
