Defect description

PACCAR Incorporated (PACCAR) is recalling certain 2016-2021 Kenworth T680 trucks equipped with a 2.1m Cab and WABCO 6S/6M ABS brake system with drum brakes. The brake systems were manufactured with a standard rear-brake ABS modulator valve instead of a quick release valve, which may exceed the intended service-brake release timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Safety consequence

Longer than expected service-brake release timing may lengthen vehicle stopping distance, increasing the risk of a crash.

In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

Safety consequence

If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

Since both intermediate side marker lamps and reflex reflectors are required, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Safety consequence

The DRLs are required to deactivate when the hazard warning lights are activated, however, the DRLs on these vehicles override the hazard flashing functionality after the brake pedal is pushed for more than two seconds. Normal hazard flashing functionality returns once the service brake is released. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."

Safety consequence

If the hazard warning lamps are overridden by the DRL, oncoming vehicles may fail to be warned, increasing the risk of a crash.

The affected vehicles are equipped with an SR-7 spring brake valve assembly that may have had the primary and secondary service brake applications installed in reverse. In the event of a failure in the primary or secondary circuit, the redundant circuit would not provide adequate service brake functionality. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."

Safety consequence

A loss of braking ability would increase the risk of a crash.

Manufacturer remedy

Kenworth will notify owners, and dealers will inspect the vehicles and correct the air line installations as required, free of charge. The recall began on September 16, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWK.

Safety consequence

If the rear wheel lug nuts are undertorqued, the wheels may separate from the vehicle, increasing the risk of a crash.

Manufacturer remedy

Kenworth will notify owners, and dealers will verify that the rear wheel lug nuts are correctly tightened, free of charge. The recall began on July 1, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. Kenworth's number for this recall is 15KWG.

Reported April 3, 2015 · PACCAR Incorporated

Potentially affected: 24 vehicles

Manufacturer campaign 15KWB · Owners notified May 29, 2015 · Vehicles built November 17, 2014 – January 5, 2015 (per NHTSA)

Defect description

PACCAR Incorporated (PACCAR) is recalling certain model year 2015-2016 Kenworth T680 and T880 trucks manufactured November 17, 2014, to January 5, 2015. The affected vehicles are equipped with Meritor MT-40-14X rear drive axles that may circulate an inadequate amount of lubricant to the wheel end hub assembly.

Safety consequence

Without adequate lubrication to the wheel end hub assembly, the bearings may fail prematurely, increasing the risk of a wheel-end fire or crash.

Manufacturer remedy

Kenworth will notify owners, and dealers will replace the defective rear drive axle and inspect the wheel ends for damage, replacing them, as needed, free of charge. The recall began May 29, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWB.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

THERE ARE NUMEROUS SERVICE BULLETINS ON QUANTUM'S WEBSITE, WWW.QTWW.COM , UNDER PRODUCTS AND SERVICE BULLETINS THAT SAY MANY DIFFERENT PARTS OF THEIR FUEL SYSTEMS WILL FAIL. IT ALSO STATES THAT THEIR BRACKET SYSTEM HOLDING THE TANKS IN PLACE WILL ALLOW THE HIGH PRESSURE TANKS TO MOVE LATERALLY THAT COULD CAUSE A RUPTURE IN THE FUEL LINES OR THE TANK ITSELF. I HAVE CONTACTED THEM TO HAVE THE PARTS REPLACED AND THEY ARE REFUSING TO CHANGE THEM OR TELL ME HOW I CAN MAKE MY SYSTEMS SAFE FOR MY EMPLOYEES TO OPERATE. I HAVE A HUGE CONCERN FOR THE SAFETY OF MY EMPLOYEES WHILE OPERATING THESE SYSTEMS UNTIL THE PARTS THAT WILL POSSIBLY FAIL HAVE BEEN REPLACED. IN ADDITION THEY ARE NOT FOLLOWING THE NFPA 52 GUIDELINES FOR THE LOCATION OF THE PRD VENTS WHICH IN THE EVENT OF A FIRE AND THE CURRENT LOCATION OF THE VENTS WOULD DISCHARGE FUEL DIRECTLY INTO THE FLAMES. THEY CURRENTLY ARE STILL NOT FOLLOWING THE GUIDELINES AS OF TODAY. AS I'M SURE YOU CAN UNDERSTAND MY CONCERNS AND WOULD LIKE TO HAVE THESE ISSUES RESOLVED FOR MYSELF AND ANYONE ELSE THAT HAS PURCHASED THESE FUEL SYSTEMS FROM THIS MANUFACTURER. I HAVE ATTACHED A FEW OF THE BULLETINS FROM THEIR WEBSITE THAT ARE ISSUES WITH MY SYSTEMS TO SHOW THAT THEY ARE AWARE OF THE ISSUES AND IF YOU LIKE I CAN SEND YOU THE EMAIL CONVERSATIONS BETWEEN MYSELF AND QUANTUM TO SHOW THAT THEY ARE NOT DOING ANYTHING TO RECTIFY OR FIX THE ISSUES. THANK YOU IN ADVANCE FOR ANYTHING YOU CAN DO TO ASSIST US IN RESOLVING THESE ISSUES AND MAKE OUR SYSTEMS SAFE FOR OUR EMPLOYEES TO OPERATE.

THE DEFROST DOORS IN THE T680 IS WEAK AND BREAKS OFTEN LEAVING THE DRIVER WITHOUT ANY DEFROST CAUSING HIS VISIBILITY TO DECREASE IN AN UNSAFE MANNER. KENWORTH HAS BEEN UNWILLING TO ADDRESS THIS ISSUE AND REPAIR IT. WHEN I CONTACTED OUR DISTRICT SERVICE MANAGER HE KNEW THE PART NUMBER OF THE REPLACEMENT DOOR ASSEMBLY FROM MEMORY AND STATED IN AN EMAIL BACK TO ME THAT KENWORTH HAS IDENTIFIED THE ISSUE AND IS WORKING TO FIX IT ON FUTURE MODELS. LABOR TO REPAIR THIS IS OVER $3000 AND THE PART IS ANOTHER $886. WE HAVE 12 OF THESE VEHICLES, SO FAR 5 OF THE 12 HAVE BROKEN LEAVING MORE THAN ONE DRIVER STRUGGLING TO GET OFF THE HIGHWAY BEFORE HIS WINDOW FOGGED UP SO BAD HE BECAME UNSAFE TO DRIVE. THE VEHICLES ARE IN MOTION WHEN THESE DEFROST DOORS BREAK AND IT CREATES A VERY UNSAFE SITUATION AS TRUCKS CAN NOT JUST PULL OVER ANY SPOT THEY CHOOSE ON THE HIGHWAYS AND WAIT FOR A WINDOW TO THAW OUT. THERE ARE 2 ISSUES THAT HAPPEN ON THESE DOORS. 1 THE DOOR IS OVERFLEXED BY THE ELECTRIC ACTUATOR MOTOR AND SNAPS THE DRIVE COGS OFF OF THE DOOR. 2 THE DOORS EITHER SHRINK OR ARE TOO SMALL TO BEGIN WITH AND THE DRIVE COG DOES NOT MAKE FULL CONTACT WITH THE ACTUATOR MOTOR CAUSING THE TEETH TO STRIP OUT AS IN THE PHOTOS ATTACHED. THE DRIVE COG SHOULD BE EXTRUDED FROM THE HOUSING BUT AS YOU CAN SEE ARE SHRUNK INSIDE THE HOUSING. *TR
