Mack Granite (gu) recalls
Risk: Overheated brakes may cause a tire blowout or fire, increasing the risk of a crash.
Risk: Insufficient tires can fail, increasing the risk of a crash.
Risk: Low turn signal visibility may not alert other drivers to a turning vehicle, increasing the risk of a crash.
Risk: The short screws can cause the hardware to separate from the suspension system and become a road hazard, increasing the risk of a crash or injury.
Risk: A separated hubcap can create a road hazard, increasing the risk of a crash.
Risk: A vehicle that drifts out of its lane increases the risk of a crash.
Risk: If the mirror detaches from the door, the mirror may strike another vehicle or pedestrian, increasing the risk of injury or crash.
Risk: The driver may operate the vehicle with the snow plow headlights on but the marker and tail lamps off, reducing the vehicle's visibility and increasing the risk of a crash.
Risk: Loss of lighting or windshield wiper function can increase the risk of a crash.
Risk: Overloaded front wheel hubs can result in premature failure of the hubs, bearings, and the related components, which can cause the front hub assembly to separate from the front axle. Because of this, the driver may lose control of the vehicle or parts may be dropped on the road, increasing the risk of a crash.
Risk: If he cap nut loosens and falls off, the yoke can separate from the axle input shaft and allow the drive shaft to disconnect, increasing the risk of a crash.
Risk: If the roll pin is missing, the steering shaft may disconnect from the yoke, resulting in a complete loss of steering and increasing the risk of a crash.
Risk: If the rear brakes overheat there would be an increased risk of a tire blowout or a wheel-end fire.
Risk: If the turbocharger oil supply line oil leaks in the proximity of the engine exhaust manifold there would be an increased risk of a fire.
Risk: If the hex nuts are not tightened to specification, the driveshaft may disconnect from the drive axle, resulting in a loss of propulsion and increasing the risk of a crash.
Risk: If the air brake system reservoir has as insufficient volume, braking performance may be affected, increasing the risk of a crash.
Risk: If the electrical cables and air lines were to fall and get tangled in the driveline, it could affect the electrical system and braking system, increasing the risk of a vehicle crash.
Risk: If the Automatic Shut-down Protection System does not operate as expected, the operator may be unable to control the increase in the engines rpms, increasing the risk of engine failure and vehicle fire.
Risk: If the engine stalls unexpectedly there is an increased risk of a crash.
Risk: If the seat belt detaches from its mounts, the seat belt would fail to properly restrain to the seat occupant, increasing the risk of injury in the the event of a crash.
Risk: A failure of the hazard warning lights could reduce the trucks visibility, increasing the risk of a crash.
Risk: Deposits of contaminants may result in the circuits being bridged, creating a high resistance short, increasing the risk of a fire.
Risk: If the nut comes loose, the hub assembly may separate from the vehicle, increasing the risk of a crash.
Risk: A loose steering shaft would result in a loss of steering control, increasing the risk of a crash.
Risk: A loss of brake function at one wheel will lead to increased stopping distances and pulling to the left or right when braking, which may increase the risk of a crash.
