2004 Freightliner Classic Problems, Complaints & Recalls

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: On certain trucks equipped with caterpillar diesel engines, the variable valve actuation oil line may wear against the sharp edge of the cylinder head if not positioned correctly.

Risk: The oil line may be cut on the cylinder head causing an oil leak and a possible fire.

Fix: Caterpillar, in conjunction with freightliner, will be conducting the owner notification and remedy for this campaign free of charge. Owners may call caterpillar at 309-675-6496, or freightliner at 1-800-547-0712.
