PTO Disabled Due to Engine Shutdown Altec has been notified of a customer satisfaction campaign by General Motors. It is possible that certain 2019–2020 model year Chevrolet Silverado 4500HD/5500HD/6500HD vehicles equipped with an aerial device may have a condition in which the aerial device operator could be stranded if the engine received a command for shut down. The vehicle is functioning as designed; however, aerial device applications were not clearly understood during the development of the power take off module (PTOM). The inspection and repair will be done by an authorized GM/Chevrolet Medium Duty Servicing dealer
