2013 INTERNATIONAL TRANSTAR

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:FAN/MOTOR

Navistar, Inc. (Navistar) is recalling certain model year 2011-2015 International DuraStar, ProStar, TranStar and WorkStar, 2012-2015 International TerraStar, 2013-2015 International LoneStar and IC Bus HC, and 2014-2015 IC Bus AC vehicles. A vehicle double battery jump start or electrical load dump event could result in an overvoltage condition of a component within the HVAC system linear power module (LPM) which is used to control the blower speed. The overvoltage condition could result in the overheating and failure of the LPM.

Risk: If the LPM overheats and fails, there is an increased risk of a fire.

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.

ENGINE AND ENGINE COOLING:ENGINE

Navistar, Inc. (Navistar) is recalling certain model year 2013-2015 International TranStar vehicles manufactured April 10, 2012, to December 12, 2014. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.

Risk: If engine oil comes into contact with a hot surface, there is an increased risk of a fire.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL

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.

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.

SERVICE BRAKES

Navistar is recalling certain model year 2012-2013 International brand ProStar and TranStar commercial trucks, manufactured from August 01, 2011, through July 10, 2012, and equipped with front brake linings listed as feature codes 0504501, 0504504, or 04EWM. The brake S-Cam tube bracket assemblies on the steer axles may fracture.

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

ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR

NAVISTAR IS RECALLING CERTAIN MODEL YEAR 2010 THROUGH 2013 PAYSTAR, WORKSTAR, TRANSTAR, AND PROSTAR, AND MODEL YEAR 2012 AND 2013 LONESTAR COMMERCIAL TRUCKS MANUFACTURED FROM JUNE 1, 2009, THROUGH APRIL 4, 2012, EQUIPPED WITH A MAXXFORCE 11 OR 13 ENGINE (FEATURE CODE 12UXJ OR 12UXH) AND WITH BOSCH ALTERNATOR FEATURE CODES 08GGN, 08GGR, 08GHG, OR 08GHH. THE ALTERNATOR CABLE MAY RUB ON THE HIGH PRESSURE POWER STEERING HOSE, POSSIBLY CHAFING ITS INSULATION AND CAUSING AN ELECTRICAL SHORT.

Risk: AN ELECTRICAL SHORT MAY CAUSE A VEHICLE FIRE POSSIBLY RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.

SERVICE BRAKES

Navistar is recalling certain model year 2012-2013 International brand ProStar and TranStar commercial trucks, manufactured from August 01, 2011, through June 12, 2012, and equipped with front brake linings listed as feature codes 0504501 or 0504504. The brake S-Cam tube bracket assemblies on the steer axles may fracture.

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

SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

NAVISTAR IS RECALLING CERTAIN MODEL YEAR 2012-2013 IC BUS CE-C, HC, AND INTERNATIONAL 9400 AND CERTAIN MODEL YEAR 2011 THROUGH 2013 INTERNATIONAL DURASTAR, PAYSTAR, WORKSTAR, TRANSTAR, LONESTAR, PROSTAR, 9200, AND 9800, AND CERTAIN MODEL YEAR 2013 INTERNATIONAL 9900, VEHICLES, MANUFACTURED FROM DECEMBER 2, 2010, THROUGH JANUARY 26, 2012, AND EQUIPPED WITH BENDIX ATR-6 TRACTION RELAY VALVES. IN EXTREMELY COLD CONDITIONS, THESE BENDIX RELAY VALVES MAY POTENTIALLY DEVELOP INTERNAL LEAKAGE. 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. ALSO, THE BRAKES MAY BE APPLIED WITHOUT ILLUMINATING THE BRAKE LIGHTS, FAILING TO GIVE PROPER WARNING TO OTHER DRIVERS.
