So I have a Jap-spec 221KW Levorg ex-demonstrator with 39K on the clock and there's a persistent rattle from the passenger-side speaker grille that's driving me nuts. I've tried stuffing high-density foam between the windscreen and the dash around the speaker grille which seems to work for a while, but it always comes back. It only happens when driving on chip-seal surfaces (which is most of NZ roads). My mate has a 2018 NZ new Levorg and it does the exact same thing, so I'm guessing there're are others out there with similar issues? Any help much appreciated as it's ruining an otherwise great car. I've had 7 Subies, (mostly GTs) and this is the only one with rattles.
