Vehicle Speed Control:accelerator Pedal 2015-11-20 · campaign 15V776000 · 15,730 vehicles
Defect: Navistar, Inc. is recalling certain model year 2013-2014 International ProStar and DuraStar trucks manufactured April 26, 2012, to April 4, 2013, WorkStar trucks manufactured April 27, 2012, to March 29, 2013, LoneStar trucks manufactured May 21, 2012, to April 2, 2013, and TranStar trucks manufactured April 30, 2012, to March 25, 2013. In the affected vehicles, the accelerator pedal position sensor can move and result in a high engine idle.
Risk: A high engine idle may make downshifting the transmission difficult and the engine brake may be disabled. These factors may hinder slowing down the truck when descending a long grade, thereby increasing the risk of a crash.
Fix: Navistar will notify owners, and dealers will recalibrate the electronic control module (ECM) to allow it to recognize that the pedal is at the idle position, free of charge. The recall began on January 19, 2016. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 15517.
