Detroit Diesel Corporation Recalls Turbochargers and Diesel Particulate Filters on Urban Buses
Release Date: 11/16/2005
(11/16/05) To ensure that its bus engines meet emissions standards and operate properly, the Detroit Diesel Corporation (DDC) has agreed to begin recalling approximately 1,250 urban transit buses for emission related repairs. The engines have experienced several problems, including particulate filter plugging and turbocharger defects. Approximately 841 of DDC's Series 50 urban bus engines will receive new turbochargers, and 993 engines will have the original diesel particulate filters replaced with improved particulate filters. Some engines will receive both a new turbocharger and an improved particulate filter. Diesel particulate filter plugging and turbocharger malfunctions can cause an engine to stall or operate improperly while emitting high levels of hazardous air pollutants.
EPA discovered the bus engine problem and its scope through transit bus fleet manager complaints, emission related defect reports, and through discussions with DDC. After DDC performed a series of tests on the improved particulate filters and filed completed emission related defect reports, EPA agreed to DDC's recall campaign.
A notification letter will be sent to all affected transit bus fleet operators by DDC informing them of the recall campaign that will be conducted at no cost to the transit bus fleet operators.
