Sutphen Chassis recalls

What is wrong

Sutphen is recalling certain model year 2009 through 2012 vehicles and equipped with meritor wabco electronic stability control (ESC) modules. See the list above for the affected models. 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.

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.

Remedy

Sutphen is working with meritor wabco to replace the control module free of charge. Please see meritor wabco defect report 11e-039. The safety recall began on december 16, 2011. Owners may contact meritor on track customer service at 1‑866‑668‑7221.

Recall number 10V416000 · Recall details

What is wrong

Sutphen is recalling 56 my 2006 fire truck chassis equipped with trw steering gears, models tas85. These steering gears contain potentially defective sector shafts with an incorrect gear tooth which may interfere with the rack-piston teeth, resulting in a sticking or binding condition.

Risk

This condition has the potential to cause the steering gear to stall and restrict the steering turning angle of the vehicle which could result in a vehicle crash.

Remedy

Sutphen is working with trw to replace the defective steering gear (please see 07e101). The recall began on march 3, 2008. Owners may contact trw at 765‑429‑1768 or sutphen at 1‑866‑287‑5549.

Recall number 08V079000 · Recall details

What is wrong

On certain emergency/fire/rescue single and tandem axle chassis, the brake air lines may have been incorrectly routed.

Risk

If the primary system malfunctioned to the point of complete failure, the improper routing would cause the rear brakes to become disabled thus requiring the vehicle to stop using only the front brakes, which could increase the risk of a crash.

Remedy

Dealers will inspect and correct the routing of the brake lines. Sutphen has inspected and corrected all vehicles involved in this campaign.
