I have a 2008 3 and my glove box rattles ALL THE TIME. Any one else have this problem and how did ya fix it. Please let me know.. I live on a dirt road and its getting worse and worse.

 

are you sure it's the glove box? I have issues with the trim at the right below the glove box, the piece that mates to the door sill cover.
As well as the door panel trim on the passenger side - I've put friction tape (just fabric hockey stick tape) between plastic parts and under the sill cover which helps a lot.
The ring attached around the speaker was not tied down fully, so it would flex and hit plastic to plastic as well. I pulled the door panel off and melted a couple more locations with a soldering iron from the rear of the panel.
The cover for the fuse box may have been rattling, some weatherstripping as a spacer worked for that.
Though there's still a rattle over there somewhere that I can't pinpoint while driving.
Oh, another thing you may run into is you can actually hear the wiring flexing that runs across the dash. If you pull dash pieces off, the first time you touch the wiring it brakes stiction between the wires. Over time of plastic on plastic (PVC wire covering) it starts making noise again in any case.
The little rattles are my biggest complaint with the car, and one of very few complaints really.

Good luck quieting your ride, let us know if there are any specific spots that were creating noise.

 

Umm, I know when I hold the glove box in place it dosen't make a noise.. I think just need to head to the dealer.

 

If you can hold it to keep it quiet, i'd assume you can also make it squeak without the car moving.... so you can find out then if it's the closing latch, hinge, or whatever that is making noise. Then you can add a rubber bumper, fabric tape like I mentioned above, or something else to keep the noisy part from making noise. Some car spray wax, or a candle rubbed on mating surfaces can keep the squeaking down as well.

good luck.

 

Please see my post. I also have this issue on the "R side and can't fix it. If anyone has found this, can you please tell us?

 

I have the same problem. Mazda even replaced the glove box door to no avail. I discovered that it was the plastic stuff, (air ducts or lights or something) right below the glovebox. I had Mazda put some foam tape under there and the car is quiet once again.

 

That ventilation duct is right below the glovebox, but just recently I found that the panel on the left side of the passenger footwell rattles too. This has been an issue only when the car's cold & hits bumps in the road. I padded the panel and have had a couple quiet days so far.
