The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
Risk: Insufficient air volume can reduce braking performance and increase 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."
Risk: 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."
Risk: Missing reflex reflectors can reduce the vehicle's visibility to other drivers, increasing the risk of a crash.
Fix: 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.

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

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."
Risk: 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 trucks are built with a driveshaft that may not transmit power to the wheels due to weld failure from corrosion.
Risk: 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.
Fix: 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.

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