I've had my 07 RL for six months now and love it.

I do have an annoying rattling noise that I perceive is coming from the passenger side.

I've checked to make sure there was nothing hiding under the seat or in the glovebox that might be the source.

The only clue I can give is this rattle usually only rears it's head when i'm driving at highway speeds.

Any clue on what could be causing this?

Thanks in advance for any feedback.

search "glove box rattle"

 

This is could likely be the heatshield on the rear pre-catalytic converter. Mine sounds like it is coming from the passenger side glove-box also, but I know with certainty it is the pre-cat.

It could also be something with the glovebox too like HEAVY mentioned.

 

Front or back? If back, e-brake cable might need to be tightened. (You can search that too.)
