When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2014 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 202014865,284 units in Canada
Lights And Instruments
Issue: 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. Safety Risk: If a driver is not warned that the ABS is not working properly, there could be an increased risk of a crash. Corrective Actions: 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).
Recall 201863272 units in Canada
Lights And Instruments
On certain trucks, the intermediate side marker lamp/turn signals do not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 108 - Lighting System and Retroreflective Devices. The intermediate side marker lamp/turn signals, mounted to the side extenders, do not include the required reflex reflectors. This could decrease vehicle conspicuity and potentially increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will install reflex reflective tape to the side extender near the intermediate side marker lamps.
Recall 2017374240 units in Canada
Electrical
On certain vehicles, the polyfuse for the spotlight could develop a short circuit in the cabin fuse box. A short circuit could result in overheating and melting of the fuse box, and could increase the risk of a fire causing injury and/or damage to property. Correction: Dealers will replace the optional polyfuse switch in the spotlight circuit with a standard fuse.
Recall 20153164,791 units in Canada
Lights And Instruments
Certain vehicles equipped with HID headlamps may not comply with the requirements of Canada Motor Vehicle Safety Standard 108 - Lighting System and Retroreflective Devices. A Daytime Running Lamp (DRL) that is optically combined with a turn signal lamp must switch off when the turn signal lamp is switched on as a hazard warning signal. In the affected vehicles, the DRL overrides the hazard flashing functionality after the service brake is applied for more than 2 seconds, which is contrary to the standard. The hazard functionality returns to normal when the application of the service brake is removed. Turn signal functionality would not impacted. Failure to warn oncoming vehicles with flashing hazard lamps could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will update vehicle software.
Recall 201519022,815 units in Canada
Electrical
On certain vehicles, water could migrate into wiper motor head and could lead to internal corrosion. This internal corrosion could form a conductive salt bridge which could result in a short circuit, causing the wiper system to fail. Loss of windshield wiping capability, should it occur during a rainy/snowy day, may compromise the driver's ability to see the road and its users, and a short circuit could increase the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will install a shield over the wiper motor to protect it from water intrusions and prevent corrosion.
Recall 2015189140 units in Canada
Electrical
On certain vehicles equipped with PACCAR MX-13 engines and Delco-Remy 40SI alternators, the alternator charge cable may chafe against an air conditioning discharge line. This chafing could lead to damage of the alternator cable's insulation and could lead to an electrical short, increasing the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will rotate the alternator cable end 180 degrees to provide necessary clearance and reattach the cable to the alternator.
Recall 20140201,646 units in Canada
Seats And Restraints
On certain vehicles, the seat belts may not comply with Canada Motor Vehicle Safety Standard 209 - Seat Belt Assemblies. Due to a defect in manufacturing, the seat belt buckle may not release as required by the standard. This could hinder egress from the vehicle in an emergency, increasing the risk of injury. Correction: Dealers will inspect and, if necessary, replace affected seatbelt buckles.
Recall 20140181,025 units in Canada
Other
On certain vehicles, the driver and passenger door latches may fail and remain either permanently locked or unlocked. If this were to occur, the driver and/or passenger(s) may not be able to quickly exit the vehicle in an emergency, which could increase the risk of injury. Correction: Dealers will replace affected door latches.

This Truck Was Park. The Paccar Engine MX13 and Chassis Harness from the Driver Side Shortaged, causing a Fire in the back of the engine and ABS Harness under the Steering Shaft. Plástic and Rubber wire insulation Melted with the fire causing it to drip on top of the water seperator cap which resulted in a fuel flame that caused even more damage throughought the outstanding components. This problem could've resulted in total loss of the unit.

THIS TRUCK IS A MISBUILD FROM THE FACTORY ON THE BRAKE SYSTEM PLUMBING. I AM CONCERNED OTHER UNITS MAY ALSO HAVE BEEN BUILT WRONG. THE TRACTION CONTROL LOCKS UP THE FRONT DRIVE AXLE BRAKES WHEN THE TRUCK SPINS A TIRE AND KILLS THE ENGINE CAUSING DAMAGE TO THE DIFFERENTIAL AND LOSS OF CONTROL OF THE VEHICLE. I HAVE IDENTIFIED THAT THE SERVICE BRAKE AIR LINES ARE HOOKED UP INCORRECTLY FROM THE FACTORY, NOT GOING THROUGH THE ABS MODULATOR VALVE. THIS ALLOWS FULL BRAKE APPLICATION TO THE FRONT DRIVE AXLE SERVICE BRAKES WHEN THE TRACTION CONTROL ENGAGES. IT ALSO MAKES THE TRUCK SO THE ABS BRAKE FUNCTION IS NOT ABLE TO FUNCTION. WE HAVE BLOWN APART 2 FRONT DIFFERENTIAL UNITS RENDERING THE TRUCK UNABLE TO MOVE. OFTEN WHEN THIS HAPPENS IT KILLS THE ENGINE SO NOW YOU ALSO LOOSE POWER STEERING CONTROL. THIS IS AN EXTREMELY UNSAFE AND ILLEGAL BUILD ON THIS TRUCK. ABS IS REQUIRED BY DOT LAW AND THIS TRUCK DOES NOT HAVE FULL ABS FUNCTION. I HAVE CONTACTED BENDIX, THE MAKER OF THE ABS AND TRACTION CONTROL THEY HAVE CONFIRMED THE WAY THIS IS HOOKED UP WILL CAUSE THE BRAKES TO LOCK UP. I HAVE ATTACHED PICTURES OF THE VALVE, YOU WILL NOTICE THAT ONE AIR LINE COMES FROM THE MODULE WHICH GOES TO THE REAR BRAKE. THE OTHER AIR LINE COMES DIRECTLY OUT OF THE ATR6 BRAKE VALVE, THIS LINE GOES DIRECTLY TO THE FRONT DRIVER SERVICE BRAKE. IT SHOULD ALSO BE RUN THROUGH THE MODULATOR VALVE FOR PROPER FUNCTION. THIS HAS HAPPENED AT ALL SPEEDS IN ICY SITUATIONS. IT HAS HAPPENED ON MOUNTAIN PASSES AND LEAVES THE DRIVER WITH NO CONTROL. URGENT ACTION REQUIRED PLEASE. THIS HAS BEEN GOING ON FOR 3 YEARS, WE HAVE SPENT MANY HOURS TRYING TO FIGURE OUT WHY THIS TRUCKS BRAKES LOCK UP. WE HAVE THE KENWORTH DEALER ALSO LOOK AT IT AND THEY DID NOT FIND THE ISSUE EITHER. CURRENTLY THIS TRUCK IS AT THE KENWORTH DEALER WITH A REQUEST FOR THEM TO REPAIR IT AND REIMBURSE US OUR COSTS.
