2017 Silverado Speaker Rattle

[SuthrnZ71]

I just started a thread and didn't see this one on the speaker rattle.  The dealership told me it's because I had the bass button all the way up.  That's how I've always had it on almost every truck/vehicle I've owned and they never did this unless blown out or something in the door panel was loose.  I will ask them to try checking the door panel.

Ha. Have to love those dealer excuses.

 

Normal.

 

Functioning as designed.

 

They all do that.

 

And now...

 

Turn the bass down.

Took mine in for something else, told them the door panel was rattling.  They replaced the whole panel under warranty, said the issue was a loose plastic moulding.
