In owners' words
The rust damage to the frame is damaged beyond anything form just regular wear and tear and driver fault. To not be remedied is a real issue. The salt used in the roads and the material used by the car companies isn’t anything myself as a consumer could prepare for.
2010 owner · NHTSA complaint 11708599
I have been shopping for a truck for a little over a year now specifically a 2012 Chevy Silverado. To date everyone I found has frame and body rust but the frame rust is so bad that most aren’t safe to drive.
2012 owner · NHTSA complaint 11659405
10s of thousands of these vehicles have the frame rotted thru and crack in the same location. it is unheard of that a frame would rot long before the body panels of the vehicle creating a nationwide road hazard.
