I have found that the steel lines running along the frame rails are rusting and found a patch in one place and the possibility of more leaks happening.

Vehicle under carriage looks more like a 30 year old vehicle. Brakes lines have failed causing extended stopping distance or swerving off road to avoid collision. Oil cooler lined ruptured and leaked oil on exhaust manifold, a potential fire hazard, especially when all the exhaust manifolds rotted as well so hot exhaust gases are not directed out the exhaust, also a concern for poisoning occupants with toxic exhaust gases. Power steering fittings rotted causing loss of steering. GM is useless, when I contacted them they said it is the environment. I asked them why a Toyota and Acura, both 8 years older showed no such failures or even signs of rust on critical components. GM responded that they couldn't answer that question. Hmmm, I wonder why. In 39 years of driving, it is the most I ever paid for a vehicle, 48,000 dollars, and the manufacturer refuses any assistance. That's the thanks for bailing them out. It has also had wires to blower motor burn, rear brake rotors rotted away at 22,000 miles, ground wires under hood have rotted and fallen of... more potential hazards, A/C compressor seized a came apart. I could go on and on. There needs to be a serious investigation into GM and.the poor quality and lack of concern for the safety of the public. It is by far the worst vehicle I have owned, ever.

I purchased 2006 Silverado new and after the 1st year noticed rusting. Just before it came off warranty (2009) the coolant line from the radiator and the brake rotors (front and rear) had rusted through. Have since replaced the rotors again and now my brake line burst open as I was driving home. Entire undercarriage is rusted (frame is peeling up in layers), there is rust coming through the bumpers, on the wheels, in the bed, inside the driver's door - basically everywhere I look (I filed a complaint with Chevrolet in 2010 about the excessive rusting and was told, after inspection by local dealer, that there was "no abnormal rusting found"). I baby this truck (it only has 26,000 miles and is not driven on the roads when they are salted) and keep it very clean. I am afraid for my safety as I do not know what is going to fail next. Today I spoke with Chevrolet again about the brake lines, again inspected at the local dealer, and was told that it was "normal wear and tear" and caused by environmental conditions. In addition, I was told that the rotors and calipers are rusted through and must be replaced. How is it possible to conclude that the corrosion is due solely to environmental factors and not at all due to material choice and lack of appropriate coating? I am only asking that they cover the replacement of the brake lines and they do not feel obligated to do so. They do not believe it is poor design or subpar materials. (neither of my other two vehicles, 1993 Toyota pickup and 2004 Volvo, show rusting of the undercarriage to the same degree as the Silverado and the brake lines of both other vehicles are completely intact. All three vehicles have been subjected to the same environmental conditions.)
