    Wow.. this forum is littered with people complaining about rattles, yet SOA tells me "no one has told us we are having rattle issues in the new 2011 models."
    If you guys haven't figured out, these cars are made with the intention of being light. The skimping on materials and sound insulation is meant to reduce weight. I too am annoyed by the rattles...but you know what, instead of complain...I fixed it. I was appalled at the fact that I buy a brand new car and there are sweaks and rattles. If I wanted a cushy, comfortable crusier, I would have bought a Caddy.

    Good ideas on the batting and thanks for the tip on the door panel....that one has been pissing me off for months.

    I have noticed a rattle which only appears doing a certain speed in a certain gear which must be the right combination to cause the vibration, sounds like it's coming from the package shelf, it's not too much of a worry, but at least i have a good idea now what is causing it from others experience.

This hole has nothing in it, the other holes already have sound dampening material inside them. Stuff strips of batting, shop rags, newspaper, whatever the heck you want to use into that hole. It will fill the gap between sheet metal and package shelf. It doesn't take much, 4-5 strips of material should do the trick.

    My other fix for the front door rattles when stereo cranked up is easy too. Remove door panel. Remove white plastic baffles and throw in trash. Install door panel. Rattle gone...
    I've got the same issue in my sedan... will be trying this fix once the tempature gets above 0 degrees f.

    Had my car for a day and it was the first thing I noticed (rattle) so I stuck a rag in the middle 'hole' in the trunk and it's gone lol.

    Dude, for now just stick a rag in the middle pre-cut hole from underneath the plastic trim (in trunk) and it'll be gone.

    Only temporarily if you don't do a more comprehensive fix. I've been there, done that and ended up pulling out the rear deck and lining it with insulation.

    Wasn't too difficult. The biggest problem was getting the side panels off--IIRC the trick was to pull perpendicular to the orientation of the panel to release the clip. It is a strong metal clip you it takes a bit of muscle. Also make sure you put something on the edge of the rear of the panel so it doesn't scrape the defroster lines and/or tint. After the side panels are off you j ust have to find all the clips with the seats folded down and get the bolts behind the side airbag emblems (carefully pry it out with a small screwdriver). While you have everything apart take your time and find all the places where plastic might rub or vibrate then line it with something. I found some clear 3M double-sided tape that worked well. I say take your time bc I was in a rush when doing my car and still have a rattle that comes out to play when it gets cold.
