I have the same problem.
It occurs when I start from a stop in the first gear and when i change into second.
I don't ride the clutch and don't keep it pressed at stop lights.
I wonder if this can/should be covered by warranty as it's happening at 30.000 km and it is present to many owners. At least here in RO on a honda forum we have about 26 people with both 4d and 5d mentioning the same problem.
Please let us know how Honda Poland handles this problem.
We are thinking about writing a letter to Honda Trading Romania to inform them of this issue and see if we can get any kind of response from them.
Have a nice day,
