2005 GMC Sierra Z71. I am the original owner. This vehicle has 18K miles, yes 18 thousand original miles. This truck does not get beat on at all, no off road etc, and it has been well taken care of since new. There is a rust issue with these trucks. On 5-19-2014, on my way to the car wash my brakes started to feel very soft and the truck was not stopping. I changed routes to my mechanics shop, and while en route lost the rear brakes. I thankfully arrived (driving very slowly) to the front of his shop. I got out and saw a puddle of brake fluid leaking out of the rear end brake lines rear lines were completely rusted. He inspected the vehicle, and as if this wasn't enough, informed that the transmission lines were also leaking (rusted). Mechanic added that I should be prepared for the fuel lines to rust through next. This line replacement job will cost me about 2K. Not to mention the issue with the lower rockers and cab corners rusting. That estimated is for another 2K. I purchased this truck to last me, and apparently GM does not build a quality product anymore. There a numerous complaints about this issue, and GM refuses to acknowledge the problem. Very unhappy!

2005 Sierra 1500 4X4 I bought this truck new 01/ 2005, the rear spring shackles failed on 02/20/2014 due to rust, I took it to the dealer and they said the rear 3ft of frame is badly rusted making it not roadworthy. Gms position is that this is somehow neglect on my part and will not do anything. The body of the truck is not rusted and still looks good. I find it unreasonable that a 9yr old truck with no body rust should have the frame so rusted as to make it unsafe to drive.

The rear upper frame mount for the shock absorber failed due to corrosion. The non-paint rubberized coating placed on the entire frame of this vehicle is flaking off and exposing the bare steel to the elements. The frame of this vehicle has more rust than should be expected on a 50 year-old truck but it is less than eight years old. The truck is well taken care of and the body shows no signs of rust. The failure of the non-paint rubberized frame coating has rendered this 2005 Sierra un-drivable.
