2012 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.

• 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.

• Seats And Restraints#2013300September 4, 2013

  1,829 units affected

  On certain trucks, a misaligned B-pillar reinforcement could affect seatbelt D-ring anchor performance. Failure of the seatbelt D-ring anchorage to restrain the seat occupant would increase the risk of personal injury during a crash. Correction: Dealers will reinforce the seatbelt D-ring anchor.

• Seats And Restraints#2012113March 30, 2012

  248 units affected

  On certain vehicles, the driver's seat base may not have been manufactured correctly and could fail. This could allow the seat to lower unexpectedly. Should this occur while the vehicle is in motion, it could result in a crash causing property damage and/or personal injury. Correction: Dealers will replace the driver's seat base.

• Fuel System#2012080February 27, 2012

  11,923 units affected

  On certain trucks equipped with a Detroit Diesel DD13, DD15 or DD16 engine, the support system for the high pressure fuel line (between the fuel pump and the fuel delivery rail) may be damaged during a service repair procedure. Incorrect torque applied to the dampener "P" clip fasteners may damage the fasteners, which could allow the clips to loosen. This could result in a cracked fuel line and a diesel fuel leak. Diesel fuel leakage may ignite on a hot engine surface and cause a fire. As well, diesel fuel spilt on the roadway could endanger other road users by making the roadway unexpectedly slippery. These issues could result in property damage and/or personal injury. Correction: Dealers will replace the high pressure fuel line and install a more robust fuel line support system.

• Engine#2011439December 22, 2011

  50 units affected

  On certain emergency vehicles, the engine shutdown system (normally provided to protect the engine in case of malfunction) may not have been disabled during vehicle assembly. Unexpected emergency vehicle engine shutdown, under certain conditions, could hamper rescue operations and place the public at risk. Correction: Authorized service facilities will disable the engine shutdown system.

• Electrical#2011236June 22, 2011

  5,924 units affected

  On certain trucks equipped with a DD15 or DD16 engine, the bolt attaching a rubber isolator to a support bracket may become loose, back out, and contact the starter cable. This could cause an electrical short, which could result in a fire causing property damage and/or personal injury. Correction: Dealers will install a new bolt and isolator, and apply thread-locking fluid to the fastener.

• Brakes#2011196May 13, 2011

  72 units affected

  On certain vehicles, the supply and delivery air lines for the foot valve may contact the engine air intake and suffer chafe damage. Rapid air loss from the supply line would allow spring brake application, causing immediate brake lock-up. Air leakage from one of the two delivery air lines would result in partial loss of brake function, which could increase stopping distance. These issues could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, reroute the air lines at the foot valve.

• Powertrain#2011172April 27, 2011

  81 units affected

  On certain trucks, the driveshaft may not have been welded correctly during the manufacturing process. This could allow the driveshaft to fracture along the length of the tube seam weld when torque is applied. The fractured tube can twist or sever, which could result in additional damage to the driveline, the vehicle to which it is attached, and any additional nearby components. Should the brake air lines become damaged, it could allow spring brake application, causing immediate brake lock-up. If this occurs while the vehicle is in motion, it could result in a crash. Also, failure of the driveshaft would result in lost vehicle propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Either condition could result in property damage and/or personal injury. Correction: Dealers will replace the driveshaft assembly.
