Manufacturer campaign 20pbc AND 20KWB · Owners notified May 26, 2020

Defect description

PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. 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.

Manufacturer remedy

PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020. The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

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

Missing reflex reflectors can reduce the vehicle's visibility to other drivers, increasing the risk of a crash.

Manufacturer remedy

PACCAR will notify owners and dealers will install reflex reflective tape, free of charge. The recall began January 15, 2019. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 18KWF, and 18PBC.

Manufacturer campaign 15KWL · Owners notified September 16, 2015 · Vehicles built January 14, 2010 – May 22, 2015 (per NHTSA)

Defect description

PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T440, T470, T660, T680, and T880 trucks manufactured January 14, 2010, to May 22, 2015, and equipped with HID Headlamps and the option for Daytime Running Lamps (DRL). 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.

Manufacturer remedy

Kenworth will notify owners, and dealers will update the cab controller software, free of charge. The recall began on September 167, 2015. Owners may contact Kenworth customer service at 1-425-828-5000. Kenworth's number for this recall is 15KWL.

The affected trucks are built with a driveshaft that may not transmit power to the wheels due to weld failure from corrosion.

Safety consequence

If the weld fails causing a loss of power to the rear wheels, the vehicle operator may be unable to move the vehicle, or may experience deceleration if the vehicle is in motion, increasing the risk of a vehicle crash.

Manufacturer remedy

PACCAR will notify owners, and dealers will replace the defective driveshafts, free of charge. The recall began on July 15, 2015. Owners may contact Kenworth customer service at 1-425-828-5000, or Peterbilt customer service at 1-940-591-4000. PACCAR's number for this recall is 15KWJ and 515-H.

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.

Incident: September 6, 2016 · Filed: January 31, 2017

THE DEFROST DOOR BROKE ON THIS TRUCK LEAVING THE DRIVER STRANDED WITH NO DEFROST AND ABILITY TO SAFELY DRIVE THE VEHICLE UNTIL THE WINDOWS CLEARED OFF. 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 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

Incident: April 7, 2016 · Filed: April 7, 2016

THE TIE ROD END DISCONNECTED FROM THE SHAFT, THERE HAS BEEN NO WORK DONE TO THE STEERING SINCE NEW. THE PICTURES SHOW THAT THE DIRT ON THE SHAFT HAS NOT BEEN DISTURBED THEREFORE THIS IS A MANUFACTURER DEFECT AND HAS NOT BEEN TAMPERED WITH AT ALL. THE VEHICLE WAS MOVING AT SLOW SPEED IN A PARKING LOT. THIS COULD HAVE BEEN A MAJOR EVENT AT HIGHWAY SPEED. I HAVE CONTACTED THE MANUFACTURER. THIS TRUCK HAS HAD REGULAR SERVICE MOST RECENT BEING MARCH 12TH, NO SIGN OF THE DEFECT WAS NOTICED AT THAT TIME AND THIS PART WAS INSPECTED. AS YOU SEE FROM THE PICTURE, THE PART MUST HAVE BEEN WEARING FOR A LARGER TIME PERIOD THAN AN IMMEDIATE EVENT. THIS PART IS USED BY MANY MANUFACTURERS FOR THEIR PRODUCTS ALSO.
