No it's not normal. If you don't want to fix it yourself (pretty easy), print this topic, take it to the dealer, and tell them to fix it: rattle/vibration noise coming from engine or exhaust.
took mine with same problem to Sierra Honda, Monrovia Ca---they found part of the problem on the bracket underneath the catalytic converter---relaligned it and most of the noise went away but re-surfaces every now and then--they said they could not nothing more until Honda Co. gets more complaints and then maybe they would recall the cars and replace the bracket with another one
Once the cause is understood, it's quite easy to fix.
I’m having the same problem,on mine it’s the plastic where the speedometer is,it came loose and rattles over every bump,not sure how to fix though
We have the rattling noise too and it’s so frustrating. We are relatively sure it’s coming from the window wipers as when we switch them on the rattling stops till the wipers stop.
