I have this EXACT same problem. I sent a video to my dealer and said I'd like it looked at next time I bring it in. I'm not sure I want to wait that long, however.
EDIT: Here's a video of the issue. It may not seem bad from this, but when you're driving it's "clanks" like that non-stop.
I've driven two different 2021 Defenders, own a Volvo XC90 and a Badlands Lux with Leather. The Badlands interior matches the use case of the vehicle. As others have said, it's not a luxury interior but I have zero issues with it. The leather is soft and the seats are comfortable.
Early yesterday afternoon, the GM at my dealer in Dallas checked the rail status and it was showing Chicago, where it had been for nearly two weeks. He was convinced it wasn’t accurate. An hour later, the Bronco arrived. Tracker still hasn’t updated.
