2008 Autocar WXLL problems

Defect

Autocar, LLC (Autocar) is recalling certain 2012-2016 Xpert, 2010-2020 Xspotter, 2008-2020 Xpeditor, 2008-2010 WXLL and WX vehicles. A worn parking brake control valve can leak air into the vent line, creating excessive back pressure and causing the parking brake to release unexpectedly.

Consequence

The unexpected release of the parking brake may allow the vehicle to rollaway, increasing the risk of a crash.

Remedy

Dealers will remove the vent line and fitting from the valve, free of charge. Owner notification letters were mailed March 23, 2023. Owners may contact Autocar customer service at 1-888-218-3611. Autocar's number for this recall is ACX-2023 ACTT-2301.

Defect

Autocar, LLC (Autocar) is recalling certain model year 2008-2014 ACX, WX, and WXLL vehicles manufactured July 30, 2007, through February 10, 2014, and equipped with certain Cummins Westport Model ISL G or ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.

Consequence

The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.

Remedy

Cummins Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Owners may contact Autocar at 1-765-489-5499 or Cummins Inc. at 1-800-343-7357. Autocar's number for this recall is A-1402.

Defect

Autocar, LLC is recalling certain model year 2005-2013 ACX, WX, and WXLL trucks built November 16, 2004, through September 10, 2012. On the affected vehicles, the air brake systems were built without the required air tank drain valve. Therefore, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."

Consequence

Air tanks with valves omitted will not drain if moisture is introduced into the tank, potentially reducing air capacity in the air brake system, which could cause a reduction in brake performance and equipment durability, thus increasing the risk of a crash.

Remedy

Autocar will notify owners, and dealers will repair the vehicles free of charge. The recall began on June 27, 2013. Owners may contact Autocar at 1-765-489-5499. Autocar's recall campaign number is A-1302.

Defect

AUTOCAR IS RECALLING 183 MY 2008-2009 WXLL HEAVY DUTY CLASS 8 VEHICLES. THE PARK BRAKE BUTTON ON THE RIGHT-HAND SIDE OF THE VEHICLE SHOULD AUTOMATICALLY SET THE PARK BRAKE AT 70-PSI DESCENDING PRESSURE ON THE PRIMARY AIR SYSTEM WHEN THE WORK BRAKE IS APPLIED. IN THE AFFECTED VEHICLES, THE PARK BRAKES DO NOT APPLY AUTOMATICALLY AT 70-PSI; INSTEAD, THEY APPLY AT 10-PSI. THE LINES BETWEEN THE PARK BRAKE VALVES MAY BE CROSSED, CAUSING THEM TO APPLY INCORRECTLY.

Consequence

BRAKING CAPABILITY WOULD INCREASE THE RISK OF A CRASH.

Remedy

DEALERS WILL INSPECT AND REPLACE/REPAIR THE NECESSARY COMPONENTS FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN ON OR BEFORE JUNE 9, 2009. OWNERS MAY CONTACT AUTOCAR AT 1-765-489-5499.

Defect

AUTOCAR IS RECALLING 690 MY 2008-2009 ACX, WX AND WXLL HEAVY DUTY CLASS 8 VEHICLES EQUIPPED WITH QUICK RELEASE VALVES (QRV). THERE ARE QRV'S IN TWO AREAS OF THE VEHICLE. THE FIRST IS IN THE LIFT AXLE AIR LINES. A LEAK IN THAT QRV WOULD AFFECT THE RATE AT WHICH THE TAG/PUSHER AXLE IS LOWERED/LIFTED. THE SECOND IS IN THE PARK BRAKE AIR LINES. A LEAK IN THAT QRV WOULD RELEASE PRESSURE ON THE PARK BRAKE SPRINGS; IF THE LEAD IS LARGE ENOUGH, THE PRESSURE WILL DROP AND SET THE BRAKES ON THE REAR AXLE.

Consequence

DRIVERS WOULD NOT BE AWARE OF BRAKE SYSTEM FAILURE AND BRAKING CAPABILITY WOULD NOT BE POSSIBLE, INCREASING THE RISK OF A CRASH.

Remedy

AUTOCAR WILL NOTIFY OWNERS AND PROVIDE INSTRUCTIONS FOR SCHEDULING REPAIR OF THE VEHICLE AT AN AUTHORIZED AUTOCAR SERVICE FACILITY, AT NO COST TO THE VEHICLE'S OWNER. THE RECALL BEGAN ON APRIL 9, 2009. OWNERS MAY CONTACT AUTOCAR AT 1-765-489-5499.

Defect

AUTOCAR IS RECALLING 127 MY 2008-2009 ACX, WX, AND WXLL HEAVY DUTY CLASS 8 TRUCKS. INSUFFICIENT TORQUE WAS APPLIED DURING THE ASSEMBLY PROCESS TO THE NUT ON THE PINCH BOLT THAT SECURES THE LOWER STEERING SHAFT TO THE STEERING GEAR BOX. IT WAS FOUND THAT THE TORQUE CONTROLLED TOOL WAS CALIBRATED TO A LOWER TORQUE RATING THAN SPECIFIED FOR THE APPLICATION.

Consequence

IF THE STEERING BOLT WERE TO LOOSEN, THE DRIVER WOULD EXPERIENCE LOSS OF STEERING CONTROL INCREASING THE RISK OF A CRASH.

Remedy

AUTOCAR WILL PROVIDE INSTRUCTIONS TO OWNERS FOR SCHEDULING REPAIR OF THE VEHICLES. DEALERS WILL TORQUE THE STEERING KNUCKLE BOLT TO THE CORRECT SPECIFICATIONS FREE OF CHARGE. THE RECALL BEGAN ON NOVEMBER 25, 2008. OWNERS MAY CONTACT AUTOCAR AT 1-765-489-5499.

Defect

AUTOCAR IS RECALLING 770 MY 2007-2009 WXLL HEAVY DUTY CLASS 8 VEHICLES EQUIPPED WITH RESIDENTIAL FRONT-LOADER APPLICATIONS. THESE VEHICLES MAY DEVELOP CRACKS MAINLY IN THE TOP FLANGE OF THE RH EXTENSION OF THE FRAME RAIL AT THE FRONT SPLAY BREAK WHERE THE RE-ENFORCING STRAPS ARE WELDED. DURING FRONT-LOADER OPERATION, RESIDUAL HYDRAULIC PRESSURE CAUSES THE FRONT LOADER SYSTEM TO PUSH DOWN ON THE BUMPER-MOUNTED BRACKETS, CAUSING VISIBLE DEFLECTION OF THE CHASSIS FROM THE SUSPENSION FRONT HANGER BRACKET FORWARD.

Consequence

THE DEFLECTION MAY EVENTUALLY RESULT IN CRACKING OF THE FRAME RAIL.

Remedy

DEALERS WILL REPLACE THE FRONT FRAME EXTENSIONS WITH THE NEW I-BEAM EXTENSION DESIGN. THE RECALL BEGAN ON SEPTEMBER 29, 2008. OWNERS MAY CONTACT AUTOCAR AT 1-765-489-5499.

Defect

CERTAIN TRUCKS FAIL TO COMPLY WITH REQUIREMENTS OF PART 568, 'VEHICLES MANUFACTURED IN TWO OR MORE STAGES, ALL INCOMPLETE, INTERMEDIATE AND FINAL-STAGE MANUFACTURERS OF VEHICLES MANUFACTURED IN TWO OR MORE STAGES.' THE GROSS VEHICLE WEIGHT RATING (GVWR) LABEL, AS APPLIED, MAY NOT BE ACCURATE. THE GVWR LABEL MAY INDICATE THAT THE VEHICLE'S LOAD CAPACITY IS HIGHER THAN THE DESIGNED WEIGHT RATING.

Consequence

DUE TO THE ERROR IN GVWR LABELING, IT IS POSSIBLE THAT A VEHICLE COULD BE OVERLOADED WITHOUT THE VEHICLE OPERATOR'S KNOWLEDGE. A VEHICLE IN AN OVERLOADED CONDITION MAY BE SUSCEPTIBLE TO COMPONENT FAILURE THAT MAY RESULT IN LOSS OF VEHICLE CONTROL, INCREASING THE RISK OF A CRASH.

Remedy

AUTOCAR WILL SEND A LETTER WHICH DESCRIBES THE DISCREPANCY IN GVWR LABELING, AND WILL INCLUDE A COMPLETE SET OF REVISED GVWR LABELS INCLUDING A REVISED INCOMPLETE VEHICLE DOCUMENT LABEL ALONG WITH INSTRUCTIONS FOR APPLICATION OF THE LABELS. THE RECALL BEGAN ON DECEMBER 7, 2007. OWNERS MAY CONTACT AUTOCAR AT 1-765-489-5499.

Defect

ON CERTAIN HEAVY DUTY CLASS 8 VEHICLES EQUIPPED WITH BENDIX SR-7 SPRING BRAKE MODULATING VALVES, THE INTERNAL RUBBER CHECK VALVE MAY LEAK CAUSING A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER THE OPERATOR PULLS THE DASH VALVE BUTTON.

Consequence

THIS COULD DELAY OR FAILURE IN APPLYING THE PARKING BRAKES WHICH COULD RESULT IN A VEHICLE ROLL AWAY, INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL INSTALL A CHECK VALVE REPAIR KIT FOR THE AFFECTED SR-7 SPRING BRAKE MODULATING VALVE FREE OF CHARGE. THE RECALL BEGAN ON SEPTEMBER 14, 2007. OWNERS MAY CONTACT AUTOCAR AT 765-489-5499.
