The problem

Pierce manufacturing (pierce) is recalling certain model year 2007-2011 arrow xtand velocity, model year 2008-2011 custom contender, impel, quantum and model year 2009-2011 saber emergency trucks, equipped with meritor wabco electronic stability control (esc) modules, manufactured from december 19, 2007, through october 7, 2011. 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.

The risk

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 fix

Pierce is working with meritor wabco and will replace the control module free of charge. The safety recall began on december 16, 2011. Owners may contact meritor wabco at 1-248-435-8001 or pierce at 1-920-832-3000.
