On certain trucks, the air tank mounting brackets may crack, which could allow the tank to detach from the vehicle. An air tank separating from the vehicle could strike another vehicle, a stationary object, or a bystander. As well, loss of an air tank would cause a loss of service brakes, which could increase stopping distances, possibly causing a crash. These issues could result in property damage and/or personal injury. Correction: Dealers will replace the air tank mounting brackets.
