Navistar has announced that they are recalling certain model year 2011 and 2012 International Durastar, Paystar, Workstar, Transtar, Lonestar and Prostar commercial trucks manufactured from November 5, 2010 through March 10, 2011 for failing to comply with Federal Motor Vehicle Safety Standard No 121, “Air brake systems (ABS)”.  They stated that the trailer ABS fault indicator lamp in the instrument cluster will not illuminate due to a programming or hardware issue with the brake system electronic control unit. An inoperable trailer ABS fault indicator may prevent the driver from being aware of a trailer ABS fault condition therby possibly increasing the risk of a crash potentially resulting in property damage, personal injury, or death.  Navistar will notify owners.  Dealers will reprogram or replace the brake system electronic control unit free of charge.  Owners may contact Navistar at 1-800-448-7825.
