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.
Ram truck owners affected by this recall may contact Chrysler at 800-853-1403 or visit the owner’s center on the Web for more information.
