Guys...anyone of u encounter these?
1) When slowing down or braking can hear 'zzzz' sound.
2) when try to accelerate or press pedal can hear  like metal 'tak tak' sound.
3) when go through uneven road or little bump sometimes can hear 'kong' sound from the front.

No need do anything.

"zzz" electrical sound & tyre noise is normal.

Not everyone will hear, notice or bother about those sound actually. I can listen, my wife say she didnt notice & so all passengers (some even ask me aback, what sound?; some say, oh OK nothing much.)
Unless U carefully listen & compare noise level wt other car that got good NVH.

Haha.. Zzzz annoy me more. Sound like electric circuit or something..
When I ask in forum end of last year or early this year, nobody know real answer. Maybe bcoz it still new at that time.

Lastly, from net search that I found.
The sound happen when some sort of dynamo system charging the battery when we decelerate or brake.

Tyre sound annoying? Can change to a better tyre. If that still annoy U, put better sound proofing. Solve problem.

bro check ur tire pressure...as mine straight from factory was pump by the manufacturer at over 35 psi.....
Reduce it then tire sounds improved...overinflated psi by the honda

Congrats bro and enjoy your ride
