2022–2023 Western Star X-Series 3-AXLE

Due to a manufacturing issue, an incorrectly routed power cable could contact a ground stud of the vehicle and short circuit. This may increase the risk of overheating and a vehicle fire.

2020–2021 Western Star CONSTELLATION

Due to a manufacturing issue, the steering shaft may separate from the steering box resulting in a loss of steering control.

2016–2018 Western Star Unknown

The bulkhead pass through power cable stud with an attached gasket seal may contact the bulkhead. If this occurs it may result in an electrical arcing, increasing the risk of vehicle fire.

2017–2018 Western Star Constellation

An internal clutch component may be outside specification and fail, which could cause this clutch component to inhibit clutch departure.

2013–2018 Western Star Western Star 2800

The retaining clip of the transmission oil cooler line to the in tank oil cooler may fail. The transmission fluid cooler hose may disengage allowing transmission fluid to leak, which could result in a fluid leak. If a rapid loss of transmission fluid occurred, it could lead to fluid on the road which may present a risk of a motor vehicle hitting the fluid and causing loss of control.

2016–2019 Western Star Unknown

The baggage and sleeper doors may separate from the vehicle door hinge.

2010–2020 Western Star Unknown

Fuel may leak from the engine's high pressure fuel rail feed lines.

2018–2020 Western Star Unknown

The exhaust gasket at the turbo/exhaust pipe join and at the exhaust pipe/aftertreatment device join may not have been installed. An audible and visual exhaust leak may be detectable from the affected areas.

2010–2016 Western Star Unknown

Fuel may leak from the engine's high pressure fuel rail feed lines.

2017–2019 Western Star Unknown

Fuel may leak from the engine's high pressure fuel rail feed lines.

2017–2018 Western Star Unknown

The internal clutch component may be outside specifications and fail, which may prevent clutch disengagement.

2011–2018 Western Star Unknown

In some vehicles clearance between the hood and the front brake hose may be inadequate, resulting in chafing of the front brake hose and a possible air leak. A damaged brake hose may reduce brake effectiveness.

2016–2018 Western Star Unknown

On certain vehicles, the power cable stud with an attached gasket seal may not protrude through the bulkhead adequately.

2007–2017 Western Star Unknown

On certain vehicles, after several hard brake applications, the brake light pressure switch may not activate the brake lights with a light application of the brake pedal.

0 Western Star 4700

The bracket attaching the secondary steering gear to the chassis may fracture if the bolt tension is not regularly checked.

0 Western Star Western Star Trucks

A certain number of Western Star model vehicles have been fitted with a supplementary ABS trailer receptacle which does not have the required circuit current rating as outlined in Australian Design Rule 35 (ADR 35).

0 Western Star 4900 & 6900

The slack adjusters may have housings with inadequate structural integrity, which may cause failure under normal operating loads.

0 Western Star DENNIS EAGLE

A certain number of Dennis Eagle 8x4 tandem steer vehicles may have been fitted with a steering pitman arm that was not manufactured to the correct specification. The manufacturing error could compromise the attachment of the steering linkages for the second steer axle to the pitman arm.

0 Western Star DENNIS EAGLE

A certain number of our Dennis Eagle vehicles may have, during the course of having a modification carried out to improve steering geometry, not had the correct torque applied to the fasteners on the steering arms (both upper and lower). If failure occurs to these fasteners, loss of control of the steering of the vehicle can occur.

0 Western Star Trucks fitted with DD13, DD15 and DD16 engines

Incorrect torque applied to the damper p-clip fasteners may have damaged the fasteners, allowing the p-clips to become loose.

0 Western Star 4800, 4900 and 5900

Certain vehicles may have an incorrect draglink fitted. Once this draglink has been modified, the product strength is greatly reduced, which leads to material fatigue and could result in loss of steering control.

0 Western Star Dennis Eagle Elite 2

The affected vehicles may have been insufficiently arc welded at the steering wheel boss where it connects to the main steering wheel frame.

0 Western Star 4900 & 6900

A bolt within an isolator may vibrate loose and unscrew, thereby coming into contact with the starter power cable and potentially creating a short circuit from the starter motor power cable to the chassis ground.

0 Western Star 4800, 4900 & 6900

Certain vehicles may have been built with incorrect routing of the fuel line which runs from the fuel filter outlet to the engine fuel pump. This fuel line can potentially rub on the plastic conduit of the main cab power harness causing it to blow the main power fuse and potentially stopping the engine. To rectify this concern, the nominated fuel line will be relocated away from this area. 273 vehicles could possibly be affected by this concern.

0 Western Star 4900, 6900

Certain slack adjusters on SISU may have been machined with a counter-bore in the slacker adjuster housing that reduced the material thickness between the worm wheel opening and the worm shaft opening

0 Western Star Various

Certain TRW TAS85 steering gears may have incorrectly machines sector shaft teeth which may cause the gear assembly to stick or bind.

0 Western Star Various

The transverse beam end castings on certain Holland Neway AD rear suspensions may not have been manufactured to the correct material specification and could fracture under normal loads. The transverse beam could drop low enough to contact the road surface, generating sparks or pieces of the end casting.

0 Western Star Various

Battery cable can chafe on the ECM (Engine control module) mounting stud.

0 Western Star Constellation

The overhead consoles, which house multiple radios, can in some cases, have insufficient strength and cause the radios to fall on or near the driver.

0 Western Star 24-DL Tie rod end

Defective drag link and ball socket steering components have not undergone correct hardening procedures during manufacture and thus can wear prematurely. This can lead to the components separating with resultant loss of steering control.
