I have been hearing a rattling noise at start up and occasionally while driving from day 1. Just left honda and the passenger side engine mounting bolts were loose. Fortunately it was an easy fix.
Both of Bolts - How Many of Bolts , I just Found 1 Loose Bolt on Lower Motor Mount was approx 1/2 Turn out Loose , so I hand Snugged
It got a Wrench able to get 3/4 + Turn on it back In ./.
