2008 Autocar WX

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.

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.

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."

AUTOCAR IS RECALLING CERTAIN MODEL YEAR 2007-2009 WX AND WXR HEAVY DUTY CLASS 8 LCOE VEHICLES. THE AFFECTED VEHICLES MAY DEVELOP CRACKS IN THE TOP FLANGE OF THE FRONT FRAME RAIL EXTENSION. OVER TIME, THE CRACK MAY PROPAGATE ACROSS THE EXTENSION BRACKET, POTENTIALLY CAUSING THE EXTENSION BRACKET TO DEFORM UNDER LOAD. THESE TIRES ARE ALL ASYMMETRICAL TREAD PATTERNS WITH "OUTER" INDICATED ON THE OUTSIDE SIDEWALL. THE OUTSIDE SIDEWALL CONTAINS THE FULL TIRE IDENTIFICATION NUMBER INCLUDING THE PRODUCTION DATE CODE.

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.

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.

CERTAIN VEHICLES WERE BUILT WITH A TELESCOPING STEERING SHAFT BETWEEN THE IN-CAB STEERING COMPONENTS AND THE POWER STEERING GEAR BOX, LOCATED ON THE VEHICLE'S FRAME. THE STEERING SHAFT HAS BEEN DETERMINED TO BE TOO LONG.

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.

ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS BUILT WITH CUMMINS ISM C876 ENGINES, THE ELECTRONIC CONTROL MODULE FAILS TO RECOGNIZE INPUTS OF THE VEHICLE ELECTRONIC CONTROL UNIT OR FROM A DRIVER ACTUATED DASH SWITCH THEREBY INCREASING THE RISK OF UNINTENDED (OR UNEXPECTED) ELEVATED EXHAUST TEMPERATURES.

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.
