Is it like a dull sound that the cricket insect makes? Near the rear left door or roof?
I haven't been able to narrow it down.
Please let me know if you find a solution.
No it’s a proper knock sound from the seat.
Your sound is more likely to be the small rubber bushes on the door. If any one of them is broken or not present the doors emit similar noise when going around in rough roads (if the noise is coming from the door). Or it is a plastic panel. Check if pressing any of the panels emit similar noise. If it’s from a plastic panel I feel it’ll be a never ending pursuit to get a solution. My new Verna has similar sounds coming from the dashboard area .
