WASHINGTON – Pierce Manufacturing, an Oshkosh subsidiary specializing in custom fire and rescue apparatus manufacturing, is recalling 724 trucks because of a potential problem with the Meritor Wabco electronic stability control modules.
The recall affects the model-year 2007-2011 Arrow XT, model-year 2008-2011 Custom Contender, model-year 2008-2011 Impel, model-year 2008-2011 Quantum, model-year 2009-2011 Saber, and model-year 2007-2011 Velocity.
Under certain road and driving conditions, vehicle body roll and road inclination characteristics may adversely affect the slip angle calculation of the electronic stability control (ESC) system. This might cause the ESC to perceive an over-steering situation and therefore apply the outer wheel brake on the front axle until the vehicle is perceived to be stable.
If the driver is slow to react during this ESC intervention, the vehicle may deviate from the intended line of travel, increasing the risk of a crash, the National Highway Traffic Safety Administration reported.
Pierce is working with Meritor Wabco and will replace the control module free of charge. The safety recall is expected to begin in mid-December. Owners can contact Meritor Wabco at (248) 435-8001.
