10- Suspension#2025610
2,464 units affected
Issue: On certain trucks, the fasteners for the axle clamp(s) may not have been tightened properly. As a result, the clamps could loosen. If this happens, the axle could move and cause a loss of steering control. Note: This recall only affects certain trucks equipped with a TufTrac Gen 2 suspension. Safety Risk: A loss of steering control could create the risk of a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify the owners by mail and advise you to take your truck to a DTNA authorized service facility to inspect and tighten the axle clamp fasteners. The axle clamp castings will be replaced, as necessary.
- Lights And Instruments#2024510
451 units affected
Issue: On certain trucks, a software problem could cause the brake lights not to work when the brakes are automatically applied during emergency braking. Safety Risk: Brake lights that don't work could cause others not to recognize when a vehicle is braking. This could increase the risk of a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and advise you to take your truck to a DTNA authorized service facility to update the active brake assist (ABA) software.
- Wheels#2024210
3,306 units affected
Problem: On certain trucks, the inner flange of the steer axle wheels may crack. As a result, a piece of the flange could separate from the wheel. Note: This special warranty program only affects ULA18xxx wheels with a size of 22.5" x 8.25". UPDATE - When Daimler Truck North America (DTNA) notified Transport Canada about this problem, they believed that it may cause a rapid air loss of a tire. After further investigation, DTNA has determined that this problem would not result in a rapid air loss. Accordingly, this safety recall was withdrawn. Safety Risk: This problem does not pose a safety risk. Corrective Actions: This is not a recall and will be addressed under a special warranty program offered by Alcoa, the wheel supplier. This notice is for information only and is not being conducted under the requirements of the Motor Vehicle Safety Act. If you notice any cracks on the inner flange of the steer axle wheels, you should contact Alcoa at 1-800-242-9898.
- Powertrain#2023422
3 units affected
Issue: On certain buses, the driveshaft could break while driving and cause a sudden loss of power to the wheels. The driveshaft could also separate from the vehicle. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Additionally, a driveshaft that separates from a vehicle could create a hazard for other road users and increase the risk of a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and advise you to take your bus to a DTNA authorized service facility to replace the driveshaft.
- Other#2023256

- Lights And Instruments#2023060
396 units affected
Issue: On certain trucks, the tail lamps do not turn on when the daytime running lamps (DRLs) are on. Canadian regulations require that, if a vehicle has dash backlighting, the low beam headlamps and tail lamps must automatically switch on when it is dark or the tail lamps must stay on at all times. Safety Risk: Driving without tail lamps in low light conditions could make the truck less visible and increase the risk of a crash. Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and instruct you to take your truck to a DTNA authorized service facility to update the parameters for the lighting system. For Western Star 4700 ZODIAC models, the service facility will replace or modify the wiring harness.

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.

Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and instruct you to take your truck to a DTNA authorized service facility to replace the affected tires.
- Engine#2022413
99 units affected
Issue: On certain trucks, a problem in the engine control module (ECM) could cause a short circuit. If this happens, the engine could stall and you may not be able to restart it.

Issue: On certain trucks, a bolt for the upper joint on the steering shaft may not have been installed correctly. As a result, the joint could disconnect and cause a loss of steering.

Corrective Actions: Daimler Truck North America (DTNA) will notify owners by mail and instruct you to take your truck to a DTNA authorized service facility to inspect the upper joint on the steering shaft, and if necessary, re-install the pinch bolt.
