I bought a 2006 sierra denali with 65000 miles on the truck in may of 2013. I lost my brakes and almost rearended a man pulling into his driveway. I also had my 3 kids and my fiance in the truck with me. I took my truck to robertsons gmc in wareham,ma and they told me my brake lines were completely rotted as well as my frame. I also had a extended warranty which did not cover it because it was a pre-existing problem. I just don't understand how gm can get away with all of these frame corrosion and brake line corrosion problems without having to fix the problems with there trucks. I have researched alot on these problems and it seems like no one is holding gm responsible and making them fix the corrosion problem.I think they should have to fix the problem like toyota did when they had frame problems so that they can stop producing vehicles that dont last 10 years without rotting away.

2006 sierra denali with just over 75,000 miles. With 1/2 block warning and only traveling at a speed of 20mph, I was unable to come to a complete stop. The brake pedal was all of the way to the floor when I ran into a van in the intersection. I felt very little resistance from the pedal and the ABS definitely did not go off. There was no snow or ice on the road surface. However after towing the vehicle to the local dealership, I was told nothing was wrong with the truck. Two independent third parties have suggested this could be a master cylinder issue even though gmc gave it a clean bill of health.
