Rattling sound

[IanAGP]

Does anyone else getting a rattling/knocking sound, I think its plastic rather than metal, when driving on a poor road surface? It doesn't happen over speed bumps, just on rough surfaces. Could it be the parcel shelf or inside a door card?

I’ve checked the parcel shelf and it does seem a bit loose, its deffo not a tight fit like on some other cars

its not your passenger seat belt buckle tapping between the plastic trim on the seat and chassis post is it ??
