Annoying noise

[txgal13]

I am getting a very annoying rattling noise in my back seat. I own a 2013 Silverado and just had a system put in by Best Buy. When I bought the truck back in January of this year, I don't think it had that noise, but it only happens when I go over bumps. Almost sounds like its in the door panel. Any thoughts on where I can check or maybe its a loose screw back there?

 

I've had a friend sit in the back seat when we drive and he can't locate the noise either.

Go back to Best Buy. They might have left hardware or a tool in the opening.

I'll second that.

Did they remove your rear seat for that "system" they put in it? If so, you me be hearing the rear seat hooks rattling. Sometimes the piece of plastic falls off when removed and you get a loose metal on metal over bumps causing a rattle.

 

OR

 

Did they snap off any of the door panel plastic pieces that plug in to keep the panel in place? May want to check that also.
