I have a 2011 GMC Sierra Standard Cab pickup truck. Iâm a disabled veteran and have this as my primary vehicle. The frame has a huge hole that developed and will need repair. The frame is rotted and soon will not pass inspection. The truck looks brand new but Engin compartment, frame and tow parts have rotted. I had the leaf spring separated from rotted frame on the highway. I swerved and almost died. GMC must replace the frame to make this right. Soon I will have no truck after giving GMC so much money. Itâs criminal what they have done.
