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.
Electrical arcing could create the risk of a fire.
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.
On certain trucks, the welds that attach the trailer hitch may crack due to improper welding. As a result, the hitch could detach from the truck while towing a trailer. Note: This recall only affects certain trucks with trailer hitches installed by Commercial Truck Equipment.
A trailer that detaches from a truck could create a risk of a crash.
Commercial Truck Equipment will notify owners by mail and instruct you to take your truck to a dealer to inspect the trailer hitch and repair or replace it, as necessary. You should stop using the trailer hitch until the inspection and repair have been completed.
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.
Sudden and unexpected movement of the vehicle could create a risk of injury or a crash.
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 clutch and update the transmission software.
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.
A window that separates from a moving vehicle could create a hazard for other drivers and nearby people.
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.
On certain trucks, the baggage and/or sleeper side doors may not be properly attached to their hinges. This could cause the door(s) to detach while driving.
A baggage and/or sleeper side door that falls from the truck could create a road hazard for others and increase the risk of a crash.
Daimler Trucks North America (DTNA) will notify owners by mail and instruct you to take your vehicle to a DTNA authorized service facility to install two reinforcement clips on each baggage and sleeper door hinge.
On certain vehicles, the bolts that join the steering and tie rod arm to the steering knuckle may not have been properly tightened. 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.
A failure of this component (steering) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
This recall was replaced by Transport Canada Recall No. 2020-488. On certain vehicles equipped with an Eaton automated manual transmission and electronic clutch actuator (ECA), an internal component within the clutch assembly may have been manufactured improperly and could fail. If this occurs, 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, increasing the risk of a crash causing injury and/or damage to property. Correction: Daimler Trucks of North America Authorized Service Facilities will recalibrate the Transmission Control Module (TCM) and replace components as necessary.
A failure of this component (powertrain) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
On certain trucks built with a Cummins X15 or ISX15 engine equipped with nylon fuel lines and a banjo bolt on the fuel pump, a blockage in the fuel cooling system may cause a fuel line to burst. This could result in a significant fuel leak onto the roadway, which would create a road hazard for other motorists. Additionally, this condition could also cause an engine stall without warning, without the ability to restart the engine. Both of these conditions may increase the risk of a crash causing injury and/or damage to property. Correction: Cummins-authorized dealers will replace the affected nylon line with a steel line.
A failure of this component (fuel system) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
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.
A failure of this component (brakes) may increase the risk of a crash or injury.
Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
