Defect

CERTAIN FREIGHTLINER SCHOOL BUS CHASSIS, HEAVY TRUCKS, AND THOMAS BUILT SCHOOL BUSES MANUFACTURED BETWEEN JULY 2002 AND JULY 3, 2007, EQUIPPED WITH BENDIX SR-7 SPRING BRAKE CONTROL VALVES. THE PARKER SCV BRASS 90 DEGREE SINGLE CHECK VALVES (SCV) WHICH ATTACH TO THE SUPPLY PORT OF A BENDIX SR-7 SPRING BRAKE MODULATING VALVE CAN BREAK APART. PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULATING VALVE, POTENTIALLY CAUSING EITHER LEAKAGE OUT OF THE SR-7 VALVE OR PREVENTING AIR FROM PROPERLY EXHAUSTING FROM THE SR-7 VALVE. ALSO, DUE TO A MANUFACTURING DEFECT IN THE INTERNAL RUBBER CHECK VALVE INSIDE THE SR-7 SPRING BRAKE MODULATING VALVES, THE VALVES CAN BECOME DEFORMED AND NOT SEAT PROPERLY.

Consequence

THESE CONDITIONS COULD EITHER RESULT IN LEAKAGE AND CAUSE A DELAY IN THE APPLICATION OF THE SPRING BRAKE WITHOUT WARNING OR POSSIBLY LEAD TO UNINTENDED VEHICLE ROLLAWAY OR BRAKE DRAG WHICH COULD RESULT IN A VEHICLE CRASH, PERSONAL INJURY, OR DEATH.

Remedy

FREIGHTLINER WILL NOTIFY OWNERS AND REPAIR THE VEHICLES FREE OF CHARGE. THE RECALL BEGAN ON JANUARY 11, 2008 TO FREIGHTLINER, STERLING, AND FREIGHTLINER CUSTOM CHASSIS OWNERS; TO THOMAS BUILT BUS OWNERS ON FEBRUARY 1, 2008. OWNERS CAN CONTACT FREIGHTLINER AT 1-800-547-0712.

Defect

CERTAIN 2004 AND 2005 FREIGHTLINER VAN, MOTOR HOME, SHUTTLE BUS, AND SCHOOL BUS CHASSIS MANUFACTURED BETWEEN JANUARY 2004 AND MAY 2005. ERRATIC VOLTAGE SUPPLY TO THE FUEL LIFT PUMP CAUSES PREMATURE WEAR OF THE PUMP. THIS PREMATURE WEAR COULD RESULT IN FUEL LIFT PUMP FAILURE AND IN SOME CASES MAY CAUSE AN ENGINE STALL CONDITION.

Consequence

SHOULD THE ENGINE STALL, A VEHICLE CRASH COULD OCCUR.

Remedy

CUMMINS WILL NOTIFY THE OWNERS OF THE FREIGHTLINER AND THOMAS BUILT VEHICLES AND WILL REPAIR THE ENGINES BY EMC RECALIBRATION AND REPLACEMENT OF THE FUEL LIFT PUMP AT NO CHARGE TO THE CUSTOMER.
