Recalls on the 2023 Kenworth T680
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 202515047 units in Canada
High Voltage
Issue: On certain electric trucks, the contactors for the high-voltage power system could open. If this happens, there could be a sudden loss of power to the wheels. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to update the vehicle software and replace a wiring harness.
Recall 202474423,441 units in Canada
Brakes
Issue: On certain trucks, poor signal strength could cause the electronic control unit (ECU) to stop working or not to work properly. As a result, some safety systems may not work, including the antilock braking system, automatic traction control, electronic stability control, active cruise control and the collision mitigation system. Safety Risks: Vehicle safety systems that don't work correctly could increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to reprogram the ECU software.

Powertrain
Issue: On certain trucks, the wiring in the right-hand shift stalk may not be properly connected. As a result, you may not be able to shift the transmission back into gear after coming to a stop.

Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, replace the right-hand shift stalk assembly.
Recall 2024121171 units in Canada
Brakes
Issue: On certain trucks, the reservoir tank for the air brake system is too small. In certain situations, this could cause reduced braking. 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 can cause extended stopping distances and increase the risk of a crash. Corrective Actions: PACCAR will notify owners by mail and advise you to take your truck to a dealership to replace or add an additional air reservoir tank, as necessary.
Recall 202300711 units in Canada
Brakes
Issue: On certain electric trucks, a programming error could cause the electronic stability control program (ESP) to not work correctly. Safety Risk: A stability control system that does not work properly could increase the risk of a crash.

Recall 20225917,491 units in Canada
Lights And Instruments
Issue: On certain trucks, a software problem could cause the instrument cluster display to freeze while driving. As a result, you may not be able to see certain information about the vehicle, including the speedometer, warnings, and malfunction tell-tale graphics.

Corrective Actions: Paccar will notify owners by mail and instruct you to take your vehicle to a dealership to update the system software.
Recall 2022470186 units in Canada
Engine
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.

Corrective Actions: PACCAR will notify owners by mail and instruct you to take your truck to a Cummins authorized service center to replace the engine control module.
Recall 20224103,041 units in Canada
Steering
Issue: On certain trucks, the steering gear may not have been assembled correctly. As a result, the steering gear could break and cause a loss of steering.
