WASHINGTON - Kenworth Truck Co., a subsidiary of PACCAR Inc., is recalling more than 3,000 MY 2011 T660, T800, W900, C500, T440 and T470 trucks manufactured from April 1, 2009, through Aug. 30, 2010. 

According to the National Highway Traffic Safety Administration, one of the four harness spade terminal connections to the chassis load center may become completely unseated. A completely unseated connection may result in a power loss to a portion of the vehicle's exterior lighting. This condition may reduce the visibility of the vehicle to other drivers, posing a safety risk.   

Dealers will inspect the harness and re-seat the female connectors on the male spade terminals. This service will be performed free of charge. 

Truck owners can reach Kenworth at (425) 828-5440. For reference purposes, this recall has been assigned No. 10V452000.
