I have an 06 model and lately noise and annoying sounds are heard from inside whenever I drive on a non smooth road. Is anyone facing this problem? and if so, how do I get rid of the noise???

 

"I have an 06 model and lately noise and annoying voices are heard from inside"

I usually leave the wife at home when I cruise in my 3...

Seriously, check the jack in the back door, I find mine comes loose an starts to squeak and rattle...

 

I took the jack and everything else out of the car but the noise is still there. One thing I noticed tho, when people sit on the rear seats most of the sounds are gone so i thought maybe the seats were loose or something. I laid the seats but still, the noise is there. Could it be the rear suspensions?

 

if u are hearing voices first thing u need to do is step away from the hummer, next call a cab and go to the nearest mental institute. now with the actual noise u are hearing i have that with my glove box that rattles a bit on my 06 h3 , so check that if u ever get out, good luk

 

Ive been having the same problem, I hear squeaking noises when I go over speed bumps and stuff, sounds like its coming from the back end, it could be the jack in the back door like canuck said. Its pretty annoying...

 

The bushings around the sway bar go bad often. Had it happen on other GM vehicles. Crawl under, give your sway bar a good wiggle..see if thats it. Also check to see if anything looks odd where they connect. The bushing can squeak and the sway bar can rattle.

 

it might be your rear tire rack. i have a noise coming from the rear of mine. when i pulled my rear tire off mine went away.

 

You didn't say where theinterior noisewas coming from but here are two suspect things you could check.

Under the rear of the truck between the muffler and the rear differential is a black box which,appears to be part of the fuel system.It is held in a bracket by one bolt. On the bottom of the mounting bracket is a metal tab.Loosen the box and bend the tab up. This will hold the box tighter and not allow it to vibrate.

The other suspect location is in the sunroof. If you have one, see if the noise goes away when he roof is fully open. If it does, only the dealer can fix it.
