2017 Kenworth T660 Recall

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 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).

Certain vehicles may fail to conform to the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 121 - Air Brake Systems and CMVSS 136 - Electronic Stability Control Systems for Heavy Vehicles. In the event that the anti-lock brake system (ABS) loses battery and/or ignition power to the controller, the ABS indicator lamp may not illuminate to warn the driver of the loss of ABS, which is contrary to the requirements of the standards. This could result in the loss of ABS function with no warning to the driver, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will reprogram the cab control module.

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).

On certain vehicles, the Engine Control Module (ECM) may develop an internal electrical short circuit that could blow a fuse in the ECM's electrical supply circuit. This could cause the engine to stall without warning and prevent the vehicle from being restarted. Engine stalling without warning would result in lost propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the ECM.
