Summary: Navistar is recalling certain model year 2007-2010 IC 3200IM commercial buses, manufactured from April 11, 2006, through December 11, 2009. If the parking brake system experiences a loss of air pressure, the parking brake may inadvertantly apply itself, either partially or fully.
Consequence: Inadvertent partial or total parking brake application may result in a driveline fire.
Remedy: Navistar will notify owners, and dealers will install a parking brake system pressure-loss warning system, free of change. The safety recall is expected to begin on, or before, November 21, 2012. Owners may contact Navistar at 1-331-332-1590.
