The hazard

On certain trucks, the bolts used to secure the fifth wheel hitch assembly to the frame may not have received adequate tightening torque during vehicle assembly. This could allow the mounting bolts to fail and the fifth wheel assembly, as well as the trailer, to separate from the tractor. A towed unit separating from the towing vehicle could strike another vehicle, stationary object, or bystander, causing property damage and/or personal injury. Correction: Dealers will inspect the mounting bolts and replace as required.
