They're cast iron. Its going to get surface rust. It won't hurt anything.

just a quick question i thought gm had a warranty for this

 

Sheet Metal (Corrosion) 3 yrs/ 60,000 km

That would cover surface rust as in the body, not the frame, at least I do not think so. I've yet to ever encounter a truck that did not show signs of light rust on the underside frame after the first major rain storm it went through.

I have this rust, rattles in the dash, strange noises under the dash when I accelerate, whats next. I've been a GM fan all my life and who knows, maybe ford and Dodge have the same issue now. But it sure does piss a guy off when a new truck has these issues. My 2006 Colorado has no rust at all. I, unlike most,.. I actually use the 4X4 weekly and my first two months of owning a new GM product I'm thinking what the hell has happened to GM. I have never had a problem with painting rusty parts when time created corrosion, but in under 3K miles, are you kidding me??? I live in California with moderate climate, but not near the ocean with salt air.

 

2011 GMC Z71 4X4, love the new truck, but am very dissapointed in new GM quality,...

+1. My '08 SD looks like someone sprayed the entire rear diff/suspension with orange paint. I ended up hitting it with the wire brush, and slopping on black Tremclad. My '00 had 6x the mileage, and looked better underneath when I sold it.

It does not cover surface rust. I had this issue on the hood of my 2002 Bonneville. When I went to my dealer to get it warrantied I was told it is a rust through warranty and until that happens GM will not cover it.
