Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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.”

NHTSA complaint #11559780, filed 2023-12

“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. …”
