Annoying Rattle Driving Me Crazy

[CF4L]

I’ve only had my car (22 w/ 35k on the odometer) for a month and I have a developing rattle from what sounds like the passenger rear door area. Doesn’t start happening until 50 or 60 mph and my family has been no help at pinpointing it while active. I can’t feel anything loose when poking around in the drive way.

Here’s a quick video so you can hear it. Warning the road noise might be loud if your speakers are up!

Any ideas??

May be the undercarriage covers rattling.... Here are a couple threads about it and the fix.

I sometimes get a small rattle from the second-row right side seat belt retractor. Too buried to get to it. Tends to quiet down when not used for a long time.
