The affected vehicles may have an improperly routed engine grid heater power feed cable which can result in the cable contacting the metal edge on the cab.

Risk: If the cable contacts the metal edge of the cab, it may cause an electrical short, increasing the risk of a fire.

ELECTRICAL SYSTEM:SOFTWARE

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.

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.

SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE

NAVISTAR IS RECALL 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)." 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.

Risk: AN INOPERABLE TRAILER ABS FAULT INDICATOR MAY PREVENT THE DRIVER FROM BEING AWARE OF A TRAILER ABS FAULT CONDITION THEREBY POSSIBLY INCREASING THE RISK OF A CRASH POTENTIALLY RESULTING IN PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.

SERVICE BRAKES, AIR:SLACK ADJUSTERS:AUTOMATIC

NAVISTAR IS RECALL CERTAIN MODEL YEAR 2011 AND 2012 INTERNATIONAL DURASTAR AND WORKSTAR COMMERCIAL TRUCKS MANUFACTURED FROM OCTOBER 19, 2010, AND FEBRUARY 3, 2011, EQUIPPED WITH GUNITE AUTOMATIC SLACK ADJUSTERS. DUE TO AN INCOMPLETE "KNITTING" OF THE IRON AT THE TIME OF CASTING, INADEQUATE STRUCTURAL INTEGRITY OF THE SLACK ADJUSTER HOUSING CAN OCCUR, WHICH COULD CAUSE THE HOUSING TO BREAK AT THE HANDLE UNDER NORMAL OPERATING LOADS.

Risk: IF THE SLACK ADJUSTER HOUSING WERE TO BREAK, THE WHEEL BRAKE TO WHICH THE SLACK ADJUSTER IS ATTACHED WOULD NO LONGER FUNCTION, REDUCING BRAKING CAPACITY AND, IN SOME CASES, CAUSING THE VEHICLE TO PULL TO ONE SIDE. REDUCED BRAKING PERFORMANCE AND/OR LOSS OF STEERING CONTROL INCREASES THE RISK OF A CRASH.

POWER TRAIN:MANUAL TRANSMISSION:SHIFT PATTERN INDICATOR

NAVISTAR IS RECALLING CERTAIN MODEL YEAR 2009-2011 INTERNATIONAL DURASTAR TRUCKS. THE PARK PAWL IN THE VEHICLE'S TRANSMISSION MAY NOT ENGAGE WHEN THE SHIFT LEVER IN THE VEHICLE CAB IS PLACED IN THE "PARK" POSITION.
