Chrysler’s newest recall involves 186,099 diesel-powered Ram 2500 and 3500 Heavy Duty trucks from the 2007-2009 model years. The trucks may be producing higher-than-normal levels of soot which can damage vital engine and emissions-control components while adding extra pollution to the air.
The soot problem stems from a software issue in the engine control module of the 6.7-liter Cummins inline-six. The problem not only triggers a check-engine light but, under certain conditions, causes the engine to produce enough soot to damage the turbocharger, exhaust gas recirculation valve, and diesel particulate filter. A clogged EGR valve could cause engine idle and stalling issues while the filled DPF attributes to increased emissions.
Chrysler’s remedy rests with a free ECM reflash that will reportedly take around 30 minutes to update. Cummins-powered Ram owners with California registrations will especially be under the gun with this recall as proof of repair will be necessary to renew annual registrations.
