I'll agree with Ducky on this, although I don't have the benefit of his experience (I'm only 46 and my hearing is good).
I have my second H3. The first one was an early manufacture '06 model and it never had a rattle at all. 20 months and 40k miles and it was still tight and noise free.
Second one is at 37k and one small rattle has just started. It is in the headliner right at the junction over the drivers door. Not very noisy, but in a bad place (right by my ear). Going back to the dealer as soon as I can manage to part with it for a few days.
Overall, both are the tightest, quietest SUV's I've ever owned (includes a Lexus RX300 that had dash rattle early on).
I anticipate number 3 being the same....
