I finally found out what was causing the rattle in my car. I have an 06 hatchback. The rattle seemed to be coming from the passenger side airbag area. Turns out the clip holding down the bottom of the right front inner fender was pushed all the way through the hole. The screw on the clip was stripped, so it took some effort to get it out. I was able to put everything back the way it should be and now the car is quiet. I remember someone else on here had a similar problem. Hope this helps out.

 

can u post pictures please. I have the same problem.

 

Sorry its taken me so long to reply. Haven't been able to get a good picture. If you turn the wheel all the way to the right you can see the clips in the wheel well. I'll try again to see if I can get a decent picture.
