2016 Western Star 4900 recalls

• Tires#2021706November 17, 2021

  948 units affected

  Issue: Certain trucks were built with tires that are not approved for use with the truck's wheels. As a result, the tires may not perform properly, or a tire could fail. Safety Risk: A tire failure could cause a loss of control and increase the risk of a crash. Corrective Actions: Daimler Trucks North America (DTNA) will notify owners by mail. The corrective actions for this recall are under development. You will be instructed to bring your truck to a DTNA authorized service facility when a repair is available.

• Structure#2019552November 4, 2019

  2,078 units affected

  Issue: On certain trucks, the strut-rod for the sleeper cab vent windows may not be properly attached. This could cause the vent window to over rotate and detach from the vehicle. Safety Risk: A window that separates from a moving vehicle could create a hazard for other drivers and nearby people. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a Daimler Trucks of North America authorized service facility to replace the vent windows.

• Brakes#2019237May 17, 2019

  110 units affected

  Issue: Certain trucks were built with air reservoir tanks that are too small in relation to the size of the air brake chambers. Canadian regulations require enough air reservoir capacity to ensure the brakes work even with heavy use or when there is a partial loss of the air system. Safety Risk: Reduced braking could cause extended stopping distances and increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their truck to a Daimler Trucks North America authorized service facility to modify the truck to ensure it meets Canadian regulations.

• Brakes#2018283May 29, 2018

  339 units affected

  Certain vehicles built with front disc brakes and a Lomax hood may not have enough clearance between the hood and the front brake hose. This could cause chafing of the brake hose, which could lead to an air leak resulting in reduced brake effectiveness and increasing the risk of a crash causing injury and/or property damage. Correction: Authorized dealers will replace the front brake hose. Note: A leaking front brake hose may not be detectable during a routine pre-trip inspection.

• Accessories#2017636December 18, 2017

  16,510 units affected

  On certain vehicles equipped with Kidde fire extinguishers with black plastic handles and valves, the fire extinguishers may become clogged or require excessive force to activate. Also, the nozzle may detach from the valve assembly with enough force that it could cause injury, and fail to discharge. In case of fire, failure of the extinguisher to function could result in injury and/or property damage. Correction: Owners will be provided with instructions on how to inspect the fire extinguisher to see if it is recalled. Replacement fire extinguishers will be supplied by Kidde directly.

• Brakes#2017583November 28, 2017

  41,763 units affected

  On certain vehicles with air brakes, after several hard brake applications, the brake light pressure switch may not activate the brake lights with a light application of the brake pedal. If the brake lights do not illuminate, following road users would be unaware of the intent of the driver to slow the vehicle, which could increase the risk of a crash causing injury and/or damage to property. Correction: Daimler Trucks North America authorized service facilities will repair the brake light pressure switch.

• Steering#2017488October 10, 2017

  11 units affected

  On certain vehicles, the castellated nut and cotter pin on the steer axle may not have been tightened to specification. This could cause the tie rod to become loose in the steer axle, which would result in audible noise and/or looseness in steering. If the vehicle were continued to be operated in this condition, the tie rod could disconnect from the knuckle, resulting in a complete loss of control of a vehicle wheel, which would increase the risk of a crash causing injury and/or damage to property. Correction: Daimler Trucks North America authorized service facilities will inspect the torque of the castellated nuts on the tie rod, and replace the tie rod stud and knuckle as necessary.

• Brakes#2017130March 10, 2017

  199 units affected

  On certain vehicles outfitted with triple compartment aluminium air tanks, the end caps of the tanks may have received incomplete welds during manufacturing. If a weld were to separate on the tanks, it would result in a rapid loss of air pressure, which could cause reduced brake performance, or unexpected application of the parking brakes, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the affected tanks with triple compartment steel air tanks.

• Seats And Restraints#2016483October 4, 2016

  1,877 units affected

  On certain vehicles equipped with a Stratosphere sleeper cab, a seat belt mount failed during testing due to an incorrect diameter hole on the seat belt anchor plate. If this condition is present, the seat belt may not properly restrain the occupant in the event of a crash, which could increase the risk of injury. Correction: Dealers will reinforce the seat belt anchor plate.

• Powertrain#2015603December 18, 2015

  6 units affected

  On certain trucks equipped with Marmon-Herrington driven front axles, flange yoke fasteners were not tightened to specification. This could allow the driveshaft to become disconnected from the axle, potentially resulting in injury and/or damage to property. Correction: Dealers will inspect bolts and tighten or replace as necessary.

• Engine#2015484October 16, 2015

  15 units affected

  On certain vehicles, the Engine Control Module (ECM) may develop an internal electrical short circuit that could blow a fuse in the ECM's electrical supply circuit. This could cause the engine to stall without warning and prevent the vehicle from being restarted. Engine stalling would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the ECM.

• Visual System#2015251June 5, 2015

  219 units affected

  Certain vehicles may not comply with Canada Motor Vehicle Safety Standard (CMVSS 101) – Location and Identification of Controls and Displays. These vehicles may have been manufactured with an odometer displaying imperial measurements instead of metric. Correction: Dealers will install a new speedometer with a metric odometer and the correct software.
