2012 INTERNATIONAL LONESTAR

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

Navistar, Inc. (Navistar) is recalling certain model year 2011-2014 International ProStar trucks manufactured May 18, 2010, to April 5, 2013, 2012-2014 International LoneStar trucks manufactured September 7, 2011, to March 25, 2013, and 2011-2013 International TranStar trucks manufactured October 18, 2010, to February 20, 2013. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.

Risk: If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.

SERVICE BRAKES

Navistar Inc., is recalling certain model year 2012-2013 International Lonestar, Paystar, Prostar, Workstar and 9900 trucks, equipped with feature code 0504501, 0504504, or 04EWM Reduced Stopping Distance (RSD) brake linings and with or without feature code 04WCS Greased For Life front air S-cam brakes. In the affected vehicles, the brake S-cam brackets may fracture.

Risk: S-cam bracket fractures may result in an inoperative brake on the affected wheel. This will cause the vehicle to pull to one side unexpectedly during braking and/or increase the stopping distance. Either result may increase the risk of a crash.

ELECTRICAL SYSTEM

Navistar, Inc. (Navistar) is recalling certain model year 2010-2015 International Lonestar vehicles manufactured October 12, 2009, to June 16, 2014, and 2009-2015 International ProStar vehicles manufactured December 16, 2008, to June 20, 2014. In the affected vehicles the electrical harness that supplies power to the HVAC system may not be of sufficient size for the electrical load of the circuit. This can result in an increase in resistance and heating at the connectors.

Risk: An increase in resistance and heating at the connectors could cause a vehicle fire.

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

Navistar, Inc. is recalling certain model year 2008-2013 International LoneStar, ProStar, and TranStar trucks manufactured February 20, 2008, through July 29, 2013 and equipped with an electronic fifth wheel jaw release system (feature code 0595BAW or 0595BAY). Due to an assembly error, the air lines at the isolation/vent valve may not be oriented correctly.

Risk: Because of the improper orientation, in the event of an air leakage at the isolation/vent valve, the 5th wheel jaw may release, unexpectedly releasing the trailer from the tractor, increasing the risk of a vehicle crash.

VISIBILITY

Navistar is recalling certain model year 2011-2012 International Lonestar, model year 2012-2013 International Terrastar and model year 2011-2013 International DuraStar, ProStar, TranStar, and WorkStar commercial trucks manufactured from June 1, 2010, through March 7, 2012 and equipped with day cab codes 16CAB, 16030, or 16196 and feature codes 16WCE, 16WCR, 16XWD, 16XWE, 16XWV, 16XXB, 16XXD, 16XXE, 16XXG, or 16XYN sun shades. The sun shade may not be properly secured to the cab roof panel which may result in partial or full separation of the sun shade from the roof panel.

Risk: If the sun shade separates from the cab roof during vehicle operation, the sudden release of the sun shade could distract the driver increasing the risk of a crash.

INTERNAL LEAKAGE CAN LEAD TO AIR PRESSURE BEING DELIVERED TO AFFECTED PRIMARY OR SECONDARY BRAKES CAUSING CONTINUOUS BRAKE APPLICATION.

Risk: UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE BRAKES TO OVERHEAT AND LEAD TO A FIRE. UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE DRIVER TO LOSE CONTROL OF THE VEHICLE, INCREASING THE RISK OF A CRASH.
