    Default Rust on frame???

    So is rust on the frame and other parts under the truck normal after only a year and a half????

    Just want to be sure this is where the extra holes are pre drilled in the frame etc.

    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 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

    Yeah I will take it in when I get time but the salt here is horrible too and the truck came from Wisconsin where they use it just as much as Minnesota I am sure, if not more.... and maybe the clown that owned it before I did never went to the car wash in the winter:slap: any way......I will have to look into what they have to say

    Will let you know when I get time to get in......

    it is majic salt... it majically makes your vehicle rust to pieces years before it should. lol

    yeah the rust on the truck in question her is probably just surface rust and can be sanded, sealed and coated properly this time with no return of the rust again in the near future, they all rust but it's sad that this one has in just a year and a half.

    my 99 tahoe only has very very light surface rust and it's over 10 years old. now my 89 has rust on it too but it's all light surface rust. granted I live in TN but on the rare occasion it snows here they salt the roads here too, I just always run to the car wash for a heavy detailed under carriage cleaning immedately after everything is dried and off of the roads again.
    I just wish GM would finally learn how to paint a vehicle so that the paint would stay on for more than 10 years.
