2018 Western Star 4700 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.

  3,071 units affected

  Issue: On certain trucks, the pass-through power stud (an electrical connection located on the bulkhead) may come into contact with the bulkhead. If this happens, there could be electrical arcing (sparks). Note: This recall replaces FL-766 (Transport Canada Recall 2018-190). If your truck was inspected as a part of that recall, but the pass-through power stud was not replaced, your truck requires this repair. Safety Risk: Electrical arcing could create the risk of a fire. Corrective Actions: Daimler Trucks North America (DTNA) will notify owners by mail and instruct you to take your truck to a DTNA authorized service facility to replace the pass-through power stud.

  966 units affected

  Issue: On certain trucks equipped with an Eaton automated manual transmission and electronic clutch actuator (ECA), a component within the clutch assembly could fail. If this happens, the broken clutch components could prevent the transmission from disengaging or shifting to neutral. This could result in unintended vehicle movement, even if the parking brake is applied. Note: This recall replaces FL-803 (Transport Canada recall 2018-714). Trucks that were repaired under that recall also require this repair. Safety Risk: Sudden and unexpected movement of the vehicle could create a risk of injury or a crash.

• Lights And Instruments#2019336July 4, 2019

  1,280 units affected

  Issue: On certain trucks equipped with electronic stability control (ESC), the brake lights may turn on when the automatic traction control (ATC) activates. Canadian regulations do not allow brake lights to turn on when the automatic traction control activates. Safety Risk: Brake lights that turn on when a vehicle is not slowing could confuse other drivers. 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. The truck will either be reprogrammed or retrofitted so the brake lights do not turn on when the automatic traction control (ATC) activates.

• 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.

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.

• Steering#2018719December 20, 2018

  31 units affected

This could lead to a separation of the tie rod arm and cause a loss of steering control. This could create a risk of a crash causing injury and/or property damage. Correction: Daimler Trucks North America Authorized Service Facilities will inspect the steering and tie rod arm bolts to ensure they are torqued correctly and install new fasteners as necessary.

• Powertrain#2018714December 19, 2018

  1,472 units affected

  This recall was replaced by Transport Canada Recall No. 2020-488.

Correction: Daimler Trucks of North America Authorized Service Facilities will recalibrate the Transmission Control Module (TCM) and replace components as necessary.

• Brakes#2018550October 9, 2018

Correction: Daimler Trucks of North America Service Facilities will inspect the bolts, and repair as necessary.

• Brakes#2018285May 30, 2018

  683 units affected
