Recalls for 2001 Freightliner Century

DEFECT #1 - SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

Posted on: 2002-01-25
Description
On certain heavy duty trucks equipped with meritor wabco pneumatic anitlock brake system (abs) valve packages, the assembly bolts on these valve packages were not tightened correctly.

Consequence
Bolts torqued below specification will not reliably prevent air leakage at the affected abs valve package interface joints once the component begins normal vehicle operation.  If air leaks develop at any of the abs valve package interface joints, brake system pressure reductions could occur during braking or normal operation with units equipped with the traction control option, potentially extending stopping distances, possibly resulting in a vehicle crash.

Corrective Action
Dealers will tighten the fasteners to the proper specification.  Owner notification began april 4, 2002.  Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact freightliner at 1-800-547-0712.

DEFECT #2 - ELECTRICAL SYSTEM:WIRING

Posted on: 2002-03-26
Description
On certain trucks, a capacitor in the power line control (plc) filter could overheat and/or ignite when subjected to reverse polarity electrical spikes.

Consequence
This could cause an electrical fire in the area of the plc filter without prior warning.

Corrective Action
Dealers will disconnect and secure the plc filter ground wire.  Owner notification began september 20, 2002.  Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact freightliner at 1-800-547-0712.

DEFECT #3 - SERVICE BRAKES, AIR:CONTROLS

Posted on: 2001-06-14
Description
Vehicle description: vehicles equipped with certain haldex brake system two and four port relay valves.  The valve may stick open when a high-pressure application is released.

Consequence
When the valve sticks open, it can result in a total loss of air from either the service or the park brake system.  The driver may lose braking ability under a service application, possibly resulting in a vehicle crash.

Corrective Action
