Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“We have had a significant amount of rust to the entire underside, trailer hitch, and both bumpers on this truck. To prevent it from rusting away, we had to have the cab and bed undercoated. We also had to replace the gas lines, as they were rotted out, which posed potential gas loss and safety issues.”

Gas gauge in dash doesn't always work, truck has to get moving, sometimes right away and sometimes a little longer. Had to replace my throttle body control a couple months prior”
