since you identified the source, just send to Honda and tell them to fix it. Should be able to be done within 1 day since you identified the source.

Just went over for the first 1k km service. They quote the estimation cost for next 10k km service is around RM500+-. Is this true?

Based on the maintenance booklet roughly including engine oil and oil filter replacement its only around RM300+- max. So I was wondering where the surcharges  coming from?

¹The staff was not willing to entertain my follow up question on this saying "You can get a quotation first on the next service, pologies but i had to attend for next customer immediately"

²This is my first Honda, I had an issue with my front passanger side power window, it creates this whizzing sound when operate. During first service they said they only entertain service appointment and critical repairs during weekends, for other matter like power windows need to reschedule different appointment on weekdays (Monday-Thursday). Is this standard accross all Honda SC?
