    no actually it's not normal. you should have had some kind of protective coating on the undercarriage to prevent that, it'll all eventually have rust on it but on a brand new truck you shouldn't have it for a while yet.

    yeah I have the black under coating on there but where the holes are it is rusty , maybe I should take it to the stealer and see what they say

    Take it in, it should have been undercoated from factory and as new as it is there's no way it should be rusting by now.

    I have an 08 and noticed that the rail under the bed where the frame and bed meet is rusted, like the machine sprayed and did not fully coat the rail, rather than mess with the dealer I am going to sand all the rust off and put a rust encapsulating coating over it and then 3m undercoat it. If I go to the dealer I get excuses, I dont like excuses, so I will save using them except for the big stuff.

    i know this has been brought up before on newer vehicles, you will have to go back to the dealership. Document this very well as they will start the run around with you, also GM has always had a different warranty for the rust on the vehicle, its actually better then the bumer to bumper warranty. i had a 94 sunbird that got rust on the seem under the door and in the doglegs, the car had over 80,000 miles when this appeared and the warranty covered it. And i know my brothers 01 sily has the warranty along with my 99 burban. if you have a really good body shop in your area take it to them for a free inspection, the can also help to push GM to get it corrected, not to mention we live in MN and body shops see this alot soe they have more experieance in dealing with warranty issues
