2019 Kenworth T800 Recall

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.

Reduced braking can cause extended stopping distances and increase the risk of a crash.

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.

On certain trucks, a spacer installed between the seat frame and the seat belt buckle may cause the seat belt to slip and not to work properly in a crash.

A seat belt that doesn't work properly could increase the risk of injury in a crash.

PACCAR will notify owners by mail and advise you to take your truck to a dealership to remove the spacer(s) and replace the bolt(s).

On certain trucks, the fasteners that attach the steer arm to the steering knuckle may fail. If this happens, the steer arm could separate from the steering knuckle and cause a loss of steering control. Note: This recall only affects trucks equipped with a Dana D-series steer axle.

A loss of steering control could increase the risk of a crash.

PACCAR will notify owners by mail. The corrective actions for this recall are under development.

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, the warning light for the tractor anti-lock brake system (ABS) may not turn on if the system loses power. If this happens, the driver will not get warning that the ABS is not working properly. Note: This problem would also cause the traction control (TC) and electronic stability control (ESC) lights not to turn on.

If a driver is not warned that the ABS is not working properly, there could be an increased risk of a crash.

PACCAR will notify owners by mail and instruct you to take your truck to a dealer to update the software for the cab control module (CECU).

On certain vehicles equipped with an Eaton automated manual transmission and electronic clutch actuator (ECA), the clutch 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: Dealers will recalibrate the Transmission Control Module (TCM).

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).

On certain trucks with an ISX15 engine and a 1.9 M cab, the engine wiring harness is missing circuits to allow the illumination of Check (CEL) and Stop (SEL) Engine Lamps and sounding of the Stop Engine Alarm. A failure to notify the operator of a serious engine problem may result in an engine failure without warning, and loss of motive power while the vehicle is in motion, which could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will inspect and/or test the engine harness for the missing circuits, and if found missing, an overlay jumper harness will be installed.

A failure of this component (electrical) 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).
