They should be responsible for repairs or replacement of the cheap made frames that rust away so fast so u ain’t gotta worry about your truck fallling apart going down the rd and the lower control arms made of cast that rust from inside out and you don’t know until breaks while driving along with camber adjustments where they can throw alignment out with a single bump. Mostly the frame replacement is major always having to plate frame or check to make sure it will be able travel long trips or haul stuff in bed or a trailer with breaking or falling off truck causing wreck frame repair is major and time consuming if you don’t have proper stuff and definitely expensive and lower control arms that’ll make a wheel come real fast and it’s time consuming and expensive too but very dangerous and breaks and causes damage right then and there at high or low speed on highways or interstates.
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.
