I mentioned the rattle to my dealer who said it's "normal" for Subaru to rattle!

Generally, I hear the rattle when driving around town, where I primarily drive, doing between 20-40 mph and below 2,000 rpm

The noise sound like its coming from the glove box, which is empty. I looked under the hood where there are shrouds on both sides of the engine the move easily when touched, and I suspect are the cause of the rattle. I have used duck tap to secure the shrouds, limit their movement, but was unable to eliminate their movement. The rattle has gotten better, less, but it's not gone.

Anyone know what purpose these plastic shrouds serve. They don't appear to do anything but rattle!

My dealer is useless. Thanks in advance for any comments or suggestions.

Are you certain it’s coming from that area ?
Maybe just check its not the hard plastic vanity mirror flip up cover vibrating against the mirror on the visor as was the case for my rattle.

My rattle was due to the lower under floor plastic sheilds most forward bolts shoulders being longer than the plastic. Rubber washers fixed, took total 4, used 10mm socket.

Those shrouds are for cosmetic and prevent water from running down the inner fender which is not painted. I would suggest you pick a nice sunny day, take both side shroud off and see if the rattle is gone. I am suspecting it maybe something else behind the glove box that is not secured. Like the cabinet filter. Good luck.

Check also the A-pillars - there had been issues with the SJ and the area where the dash speakers, the dash panel and the A-pillar trim meet up.

I'd also suggest taking a member of the service staff on a test drive so that they can hear the sound. The Forester should still be covered by the 3/36 bumper to bumper warranty and - even if they say it's normal - it should be looked at and fixed if it is a rattle. Now know that there are some sounds that are inherent with a flat-4 motor (a growl) that some may not be used to and may consider a rattle or something.

If the dealer does not want to repair what is an issue, go to another dealer and/or get Subaru of America involved.

Those trim pieces cover the gap where fender bolts to bracket. If you suspect they are the source of the rattle yuo can remove and cut a piece of eggshell foam to fit. A dab of silicon on the bracket will hold foam secure and reinstall trim.

2 things I've noticed on mine that cause a rattle ( Sport) version. The sunroof cover backs away slightly and the passenger seat belt flipped around the metal taps the plastic, those are the most annoying so far.

I’ve experienced the sunroof cover rattle, too. Re-closing and re-seating it resolved the rattle.
