Two months ago, Meritor Wabco Vehicle Control Systems issued a recall of certain electronic stability control (ESC) modules shipped to North American Vehicle manufacturers from August 2005 through September 2011. Meritor advises that 10,700 units could be affected.

According to the news release, 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 system. “This might case 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.

Meritor Wabco is working with several fire truck manufacturers to identify and vehicle owners of the recall. Fire truck manufacturers include: Pierce Manufacturing, E-One, Sutphen, HME, Ferrara and American LaFrance.

ESC modules being recalled include part numbers: 446 065 020 0; 400 850 179 0; 400 850 195 0; 446 065 027 0; and 400 850 185 0. Owners may also contact the National Highway Traffic Safety Administration’s Vehicle Safety Hotline at 888-327-4236 or go to SaferCar.gov. Or contact Meritor Wabco at 248-435-8001.
