Problem: 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.

Risk: 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.

Fix: 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.

Problem: Certain 2004 and 2005 thomas built c2 school buses and freightliner business class m2 heavy trucks manufactured between june 2004 and march 2005. The anchor/pivot bolt supplied with the park brake is defective and could fatigue fracture prematurely, resulting in the park brake failing to apply.

Risk: If the park brake anchor bolt fatigues and ultimately fractures, the park brake may not function and there may be no indication to the driver of the malfunction when the park brake is set. This may cause the vehicle to roll away without warning, which could result in a crash.

Fix: Freightliner will notify its owners and inspect and replace defective anchor bolts free of charge. The recall began on march 7, 2006. Owners may contact freightliner at 1-800-547-0712.

Problem: Certain my 2004 freightliner business class m2 and thomas built saf-t-liner c2 school buses manufactured between july 26 and october 29, 2004, equipped with a caterpillar c-7 engine and borg-warner kys 4735 35480 55 engine fan. The fan shroud may be drawn back into the fan at high engine speeds when the fan clutch engages. Due to reduced clearance, heavy contact between the fan and the shroud may cause the fan blade to fracture.

Risk: The fan may fracture and pieces may separate from the fan blade. In certain conditions, this may present a hazard to people near the vehicle with the hood open and the engine running.

Fix: Freightliner will notify its customers and replace the engine fan with a fan that has a different mounting offset free of charge. The recall is expected to begin on january 16, 2006. Owners may contact freightliner at 1-800-547-0712.

Risk: This can result in fan breakage, resulting in vehicle damage or personal injury.

Fix: Dealers will replace the engine cooling fan free of charge. The recall began on june 8, 2005. Owners may contact freightliner at 1-800-547-0712.

Problem: On certain trucks, incorrect springs were installed in the exhaust port of certain air management unit (amu) solenoid valves and they may not turn off after actuation.

Risk: Depending on the function affected, this could result in rear suspension air pressure loss, malfunction of the engine brake, permanent engagement of the rear axle differential lock, or prevent engagement of the fifth wheel slide lock. If the warning indicators in the dash are not heeded, a crash could occur.

Fix: Dealers will replace the affected valves. The recall began june 29, 2004. Owners should contact freightliner at 1-800-547-0712.

Problem: On certain trucks equipped with manual transmission, the tapered joint that attaches the shifter to the transmission may become loose making it difficult to put the transmission into gear.
