I went to get the vehicle inspected today and was told it failed due to the chassis frame in the rear being rusted thru. This could cause the suspension to collapse any time. I see on the internet that multiple others have and are experiencing the same with the Sierra and Silverado. My vehicle has unlimited washes and has been washed 40 times a year and looks new from the outside.

The frame is so rotted it will not pass state inspection.
