Frame Rust problems of the 2014 GMC Sierra 1500

There is a service bulletin from gm about frame rust on all GMC 2014 1500 sierra and chevy 2014 silverado 1500 light duty pick up trucks. The frames and some important bolts are highly rusted. They only touch-up spots they can access at the dealership. The facility where they were produced used a poor quality waxy paint coating. The dealership cannot guarantee a complete solution for this frame rust. This is a very dangerous problem in the future of the life of the truck. The frame could decay and the bolts can break off. This is not fair for a $40,000 to $60,000 truck. You can spot the rust right from the dealership new truck lot. I read on the gm truck forum on the internet hundreds if not thousands of these trucks have this issue. I will feel very unsafe driving this truck a few years from now. There are some photos of a few rusted areas in the gm service bulletin which you obtain.

Radiator leaking from top corner driver side and passennger also rust on frame.

For over 45k miles I have complained off a vibration coming from the rear of my GMC sierra at 65 to 75 miles per hour. My supporting dealer that I purchased it from can't find the problem and is most likely out of business. This is an ongoing issue. Recently I went under the truck to find the entire frame is rusted from the gas tank back to the rear off the vehicle around the spare tire and elsewhere. Whats wrong with gm manufacturing, are they that cheap, that no paint is place on the frame. Additionally the chrome wheels that came with the vehicle are corroding yet another cheap process that gm refuses to address. Mind you I have always fixed and repaired my own vehicles. I have washed this vehicle so much by using a cold water hose under the vehicle and the top as well to get the salt and brine used by the northern states off the car and yet I still get the corrosion. How do I get gm. To fix the wrongs they have produced.
