“I bought a brand new Gmc in san diego ca. I took it home to discover that the undercarriage is cover in rust. Everything from the tie rods, to the drive shaft. Anything metal is covered in rust including the frame. Its not a surface rust,the rust is corroding these parts already and the truck is brand new. How could this be sold as a brand new truck? This is a safety issue as well. We do not have snow here that would have sprayed salt on he truck to do this. This truck has been corroding for some time now even tho they said it was just built. …”
