I bought a brand new 2010 Silverado Crew Cab LT in July of 2010. Within 3 months of owning it i noticed rust spotting on the chrome of the rear bumper. Within 4 months there was rust on the front and progressively worse on the rear. My dad bought the same exact truck a month after me and rust began to show up on his bumpers as well. I called my local dealership (which isnt the one that i bought it off of but i dont think that matters) and asked if they would either replace the chrome endcaps or possibly install the fiberglass endcaps so that it couldn't happen again. They rudely told me that its not covered under the warranty and to go "buff it out" unless i wanted to pay for new bumpers. I called them around November of last year and since then have not brought it to their attention because ive been too busy and assumed that their response would be the same as before. I know other people on here are having more severe problems than just a little rust, but who in their right mind wants to drive around a brand new vehicle and have it look like sh*t because of faulty factory parts.
