2013 INTERNATIONAL WORKSTAR

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.

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.

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.

POWER TRAIN:AUTOMATIC TRANSMISSION

Navistar Inc. (Navistar) is recalling certain model year 2010-2011 IC bus 3200, model year 2012 and 2014 IC bus CE and model year 2011-2013 IC bus HC transit buses and model year 2008-2013 International 4300 and model year 2013 International Workstar commercial trucks equipped with Eaton hybrid automated transmissions. The software controlling the affected transmissions may improperly raise the vehicle's engine speed during downshifts without the driver's input.

Risk: The increase in engine speed may result in unintended acceleration, increasing the risk of a crash.

EXTERIOR LIGHTING:HEADLIGHTS

Navistar, Inc. (Navistar) is recalling certain model year 2013-2015 International WorkStar vehicles manufactured March 16, 2012, to October 1, 2014. In the affected vehicles, the headlight low beam and ground circuits may have been reversed at the headlight connector resulting in reduced light output. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: Reduced light output may impair the driver's vision, increasing the risk of a crash.

SERVICE BRAKES, AIR:DISC:CALIPER

Navistar, Inc. (Navistar) is recalling certain model year 2013-2015 International DuraStar vehicles manufactured November 2012 through December 2013, International WorkStar vehicles manufactured December 2012 through January 2014, and 2014-2015 International TranStar and International ProStar vehicles manufactured January 2013 through February 2014. The affected vehicles are built with air disc brake feature codes 04WEY, 04WEZ, or 04WZK. These vehicles may have an incorrect number of bolts mounting the brake caliper to the caliper mounting plate and some of the bolts may be improperly torqued.

Risk: If the air disk brake caliper has loose or missing bolts, the air disk brake caliper may come loose from the mounting plate causing the vehicle to pull left or right while braking and lengthening the distance needed to stop, increasing the risk of a crash.

ENGINE AND ENGINE COOLING

Navistar is recalling certain model year 2012-2013 IC Bus brand model 1300FBC, CE, HC, and RE buses; model year 2011-2013 International brand model Durastar, model year 2013 International brand Workstar trucks; model year 2013 Holiday Rambler brand model Ambassador and Endeavor vehicles; and model year 2013 Monaco brand model Diplomat and Knight vehicles. These vehicles were manufactured August 5, 2010 through September 6, 2012 and are equipped with certain 2011-2013 model year I-6 engines with feature codes 12NUK, 12NUL, 12NUM, 12NUN, 12NUP, 12NUR, 12NUS, 12NUT, 12NUU, 12NUV, 12NUX, 12NUY and 12NUZ. The injection pressure regulator (IPR) harness wire may break due to vibrational damage. This could cause an unexpected shut down of the engine.

Risk: An unexpected engine shut down while driving may increase 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.

STEERING

Navistar is recalling certain model year 2013 International brand LoneStar, ProStar, and WorkStar commercial trucks, manufactured from April 22, 2012, through October 29, 2012, and equipped with steering wheel feature codes 05CAW, 05CAX, 05CAZ, 05CBA, or 05WBD. The steering wheel may not have been completely welded to its mounting hub.

Risk: A steering wheel with an incomplete weld may separate from the steering wheel mounting hub, leading to a loss of vehicle control and increasing the risk of a 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 HEADLIGHT BEAM CIRCUIT AND THE GROUND CIRCUIT ARE SWITCHED AT THE HEADLIGHT CONNECTOR. THE SWITCHED CIRCUITS AFFECTS THE HEADLIGHTS WATTAGE, RESULTING IN THE BUMPER HEADLIGHT BEING DIMMER THAN ALLOWED BY FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT."

Risk: A DRIVER'S REDUCED VISIBILITY OR THE TRUCK’S REDUCED VISIBILITY DUE TO INADEQUATE HEADLIGHT WATTAGE, MAY INCREASE THE RISK OF A 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.
