I have a rattle noise coming from my passenger side and it's coming from the back of the passenger seat rattling in my cx3maxx. I had the same problem in my Honda.

Are you sure it isn’t the rear seats which are known to rattle if they are not stowed properly. Look at the release buttons and if there is any red showing, release them and give them a firm push back until the button comes flush and no red is showing.
