2008 Freightliner MT55 Problems, Complaints & Recalls

Problem: Daimler trucks is recalling certain model year 2008 through 2010 freightliner m2, custom chassis mt55, and sterling acterra vehicles manufactured between april 4, 2007 and july 15, 2009, equipped with cummins isc cm2150 and isl cm2150 model diesel engines. The vehicles may be designed with a hard wired, dash-mounted switch that enables the vehicle operator to inhibit aftertreatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures. Due to an issue with the logic in the ecm software in these engines, the switch may not function correctly, leading the operator to believe that the switch is in "inhibit" mode when it is not.

Risk: This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, or a fire.

Fix: Daimler trucks is working with cummins to repair the engines free of charge. Please see cummins' defect report 09e-046. The safety recall is expected to begin during november 2009. Owners may contact cummins at 1-800-diesels (1-800-343-7357) or daimler trucks at 1-800-547-0712.

Problem: Cues, inc. Is recalling certain model year 2007-2009 service vehicles built on various chassis equipped with carrier airv ceiling units, model nos. 68rv0010ba, 68rv0012ca, and 68rv0010ea. The heater element in these assemblies may be defective which could cause the unit to create smoke or sparks.

Risk: This defect could result in a fire.

Fix: Cues is working with carrier to remedy the affected vehicles. Repairs will be made by carrier free of charge. Please see carrier's defect report 09e-053. The safety recall began on january 5, 2010. Owners may contact carrier at 1-877-584-7059 or cues at 1-407-849-0190.

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.
