Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Exhaust manifold bolts are snapping off one by one. This is causing exhaust fumes to enter the cab of the truck making the driver sleepy or sick from the fumes. After talking to g.m mechanics a lot of the chevy 3/4 ton with 6.0 motors are doing this. This is a bad safety issue. G.m denies there is a problem.”
