Hi, I too own an HRV VTi and have the same problem. Mine has a build date of Feb 2018 and I first noticed the problem after around 10 months of ownership. I spent months thinking it was my imagination before reporting it to my local Honda Dealer. I like sitting in an elevated position so set my seat to its highest setting. After just 1 hour of city driving, it requires 3 lifts of the manual lever to restore the seat to my preferred position. Accordingly, after around a week of driving it requires 15 to 20 lifts to get it back to my preferred position. In a week I only drive around 6 hrs. I have been dealing with both the Honda dealership and Honda Australia for over 8 months with this problem and they will not cover under warranty claiming that it's caused by, "external influence". So much for a 7-year warranty? Any tips anyone?
