Recall 10V037000: 2009–2010 International Lonestar, 2009–2010 International Prostar

The problem

Navistar is recalling certain model year 2009-2010 international prostar and lonestar trucks equipped with feature code 04azt roll stability control. The air line that supplies the traction solenoid valve of the roll stability control (rsc) system may have been connected to an incorrect port on the air tank. This condition will affect air modulation to the trailer brakes if rsc is activated during a roll stability event. This condition at no time affects the normal design function of the tractor and trailer service brakes when activated by the driver, or the function of the tractor rsc system.

The risk

Less than optimal rsc control of the trailer brakes during a roll stability event may increase the risk of a crash which can result in property damage, personal injury, or death.

The fix

Dealers will inspect and relocate the air line that supplies the rsc traction solenoid valve to the correct port on the air tank. This service will be performed free of charge. The safety recall began on february 19, 2010. Owners may contact navistar at 1-800-448-7825.
