Chrysler is voluntarily recalling 186,099 2007-09 Dodge Ram 2500 and 3500 Heavy Duty pickup trucks equipped with 6.7-liter Cummins diesel engines to fix an issue that could cause the check engine light to illuminate or, under certain conditions, cause the engine to produce heavy levels of soot that could damage the turbocharger, exhaust gas recirculation valve and diesel particulate filter and result in increased emissions.
To fix the problem, Chrysler dealers will update the software in the engine control module. The free ECM reflash takes about a half-hour to complete.
If you live in California and own one of the trucks affected by this recall, you'll need to provide proof of repair before you can renew the truck's annual registration.
Owners with questions or concerns can contact Chrysler at 800-853-1403.
