I had the same issue. Rattling noise, only heard inside the cabin, whilst in D and with foot on the brake (more apparent at low idle, which increased vibration in the car). Engaging the handbrake would generally stop the issue. The problem started to become annoying after about 1000k's. At its 3500k service I asked them to check it, they adjusted the handbrake, which hardly made a difference. It progressively got worse, eventually loud enough to stand out over the radio. So took it back to Macarthur Ford, Narrellan, who said they would sort it out, had the car all day, said they fixed it. Within 30 minutes it was back. Called them up, said they couldn't really do anymore, it was a known issue and that Ford was working on a fix. So a letter to Ford the next day resulted in a call to explain that they would fix the issue ASAP. Took it back down the Macarthur Ford, they had it for an hour, and it was fixed. So at 4000k's it was sorted. Now just ticking past 10000k's its started to come back. Exactly the same issue. Looks like another letter to Ford is required. Apart from this issue, which is hard to overcome when your sitting in a new, $45,000 ute, that sounds like its falling apart to the shock of the passenger, I have enjoyed the way the car drives and looks.
