Summary

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.

Consequence

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.

Remedy

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.
