2010 PIERCE SABER

ELECTRICAL SYSTEM

Pierce Manufacturing Inc. (Pierce) is recalling one model year 2009 Enforcer emergency vehicle and certain model year 2009-2013 Arrow XT, Saber, Velocity, Impel, Quantum, and Commercial vehicles. The trailer connector circuit was wired such that the stop signal overrides the turn signal and the trailer lights do not indicate a turn when brakes are applied.

Risk: The absence of trailer turn signals may confuse other drivers, increasing the risk of a crash.
