The official notice
Defect
Certain C1500, C3500, K1500 and K3500 vehicles may have below specified torque on the optional trailer hitch attaching fasteners. This could allow the trailer hitch to move under towing loads and eventually lead to failure of the fasteners. If this occurs while a trailer is being pulled, the hitch and trailer could separate and a crash could occur without prior warning.
Safety Risk
No risk description available.
Remedy
Trailer hitch will be inspected for evidence of hitch movement and if movement has occurred, the fasteners will be replaced and correctly torqued. If no movement has occurred, the attaching fasteners will be tightened to the specified torque.
