Exterior Lighting

Jul 22, 2015 · NHTSA campaign 15V458000 · 12,551 vehicles

Problem: 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."

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

Remedy & notes

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.

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.

Engine

May 26, 2015 · NHTSA campaign 15V309000 · 4,823 vehicles

Problem: PACCAR Incorporated (PACCAR) is recalling certain model year 2010-2016 Kenworth T440, T800, and W900 trucks manufactured August 31, 2009, to April 20, 2015, and 2008-2015 Peterbilt 320, 337, 348, 365, 382, and 384 trucks manufactured July 27, 2007, to April 28, 2015, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.

Risk: If engine oil comes into contact with a hot surface, there is an increased risk of a fire.

Remedy & notes

Cummins will notify owners on behalf of PACCAR, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Kenworth customer service at 1-425-828-5000, Peterbilt customer service at 1-940-591-4000 or Cummins Inc. at 1-800-343-7357. PACCAR's number for this recall is 15KWH and 515-G.

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.

Problem: PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T270, T370, T440, T470, C500, C540, C550, T660, T800, W900, and 963 trucks manufactured November 1, 2010, to April 6, 2015. In the affected trucks, water may leak into the wiper motor.

Risk: As water leaks in, the wiper may cease to function on the 'intermittent' setting, reducing the driver's visibility and increasing the risk of a crash. Additionally, the water may cause corrosion which, over time, may result in an electrical short, increasing the risk of a fire.

Remedy & notes

PACCAR is still developing and testing a remedy. The recall is expected to begin in July 2015. An interim letter was sent to owners on July 2, 2015. The recall began on September 2, 1015. Owners may contact Kenworth customer service at 1-425-828-5000. PACCAR's number for this recall is 15KWF.

Problem: Paccar is recalling certain model year 2011-2012 Kenworth T270/370, T440/T470, T800, T660, W900 and C500 vehicles manufactured between October 18, 2010, and January 28, 2011. Certain cast iron slack adjuster housings, which transmit braking force from the brake chamber push rod to the brake cam tube, May include a flow notch in the handle portion of the housing due to an error during the casting process. A flow notch in the handle portion May reduce the effective cross section structure and cause the slack adjuster housing to fracture.

Original NHTSA wording

Risk: If the slack adjuster housing were to fracture, the wheel brake to which the slack adjuster housing is attached would no longer function, which could increase vehicle stopping distances, and if mounted on the steer axle, could cause the vehicle to pull to one side during braking, increasing the risk of a crash.

Original NHTSA wording

IF THE SLACK ADJUSTER HOUSING WERE TO FRACTURE, THE WHEEL BRAKE TO WHICH THE SLACK ADJUSTER HOUSING IS ATTACHED WOULD NO LONGER FUNCTION, WHICH COULD INCREASE VEHICLE STOPPING DISTANCES, AND IF MOUNTED ON THE STEER AXLE, COULD CAUSE THE VEHICLE TO PULL TO ONE SIDE DURING BRAKING, INCREASING THE RISK OF A CRASH.
