DelrayG63

I have a 2013 G63 with an annoying noise/rattle which seems to be coming from the drivers side rear door. It happens over any small bump and is driving me crazy. Any ideas? Any suggestions? Is it possible to install sound deadening material inside all doors? If so, where might one look to get it installed?

Still under warranty , then back to the dealer.
Could be nothing, but also could be the window regulator which tends to be a common problem on G-wagens.

Also make sure your door locks and strikers are lubricated.
Cargo door tends to get a plastic/plastic squeak if not kept lubricated.

Put electrical tape on the metal prongs that lock into the door frame when closed. Do that to all 5 doors and voila.
