PACCAR Incorporated is recalling 355 model year 2016 Kenworth W900 trucks because they pose a crash hazard. When the truck’s headlamps are switched from low beam to high beam, the low beams are deactivated and there is a chance that the high beams could be delayed, leaving the headlamps off. The headlights will work again if the driver switches back to low beams.
The temporary delay in activating the high beam head lamps reduces the driver’s visibility and therefore increases the risk of a crash. It also causes noncompliance with FMVSS 108. The defect is caused by overcurrent of the chassis node when the high beams are activated. Kenworth will notify owners, and dealers will alter the wiring harness to enable the high beams to illuminate, free of charge.
