Rattle when going over bumps.

[Inhouse Bob]

My Genesis auto has a little clattering noise that comes from the drive train when it is warming up. It is pretty much universal on this model. Folks write endlessly on forums about it and spend many hours at dealerships trying to sort it out. Me, I just turn up the music a bit and voila! It's gone.
I had a lot of noises coming from the headlight bucket. I put 1/8 inch packing foam around everything and it took care of the problem. Good luck with yours!
