I have a 2018 SVR with only 7k miles on it and now the sunroof while open will rattle. But not when closed. I also hear some slight interior creaks when reversing out of my garage. I expected some rattles at some point but surprised to hear at less then 10k miles and a few months shy of a year old. It's a fantastic car and there is actually nothing else out there I really like so fingers crossed it doesn't get much worse. 2018 Range Rover Sport SVR – Bosphorus Grey

So, got the car back today. They diagnosed the noise was coming from the OSF lower rear arm bottom ball joint (whatever that is!!) which they’ve replaced. It’s cured the problem so fingers crossed it doesn’t return.

The Tech guy suspected it was a manufacturing fault with insufficient grease being put on the joint before being sealed, but who knows. Whether it’s shoddy manufacturing or poor quality control - or both - it’s unacceptable on a new car, especially one at this price. Still, driving it home reminded me how much I love driving it. It’s such a shame they can’t build them properly. Maybe they’ll have more luck with the new Defender in Slokavia...

That sounds similar to what I suggested as the hushes / arms were replaced on mine luckily warranty too. Hope it stays sorted for you now 👍
