NHTSA recall 11V590000
Electronic stability control (esc)
International Prostar
The defect
Navistar IS recalling certain 2012 international prostar commercial trucks manufactured from march 22, 2011, through december 9, 2011, equipped with feature code 04azx meritor wabco electronic stability control (esc) units. 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 remedy
Navistar will notify owners, and dealers will install a new esc module free of charge. the safety recall began during february 2012. owners may contact navistar at 1-800-448-7825.
