WASHINGTON, D.C. --- Paccar Inc. is recalling 178 MY 2008-2010 Kenworth trucks and MY 2009-2010 Peterbilt trucks built on a Cummins diesel engine.
According to NHTSA, the vehicles may be designed with a hard-wired, dash-mounted switch that enables drivers to inhibit after-treatment diesel particulate filter regeneration in environments where the driver believes elevated exhaust temperatures pose a safety hazard. Because of an issue with the logic in the ECM software in these engines, the switch may malfunction.
