    Cummins recall

    Cummins agrees to recall roughly 500,000 MD, HD trucks with faulty emission controls

    Cummins agrees to recall of roughly 500,000 M-D, H-D trucks with faulty emission control systems

    On July 31 the US Environmental Protection Agency (EPA) announced that Cummins Inc will voluntarily recall roughly 500,000 model year 2010-2015 medium- and heavy-duty trucks. This is reportedly the largest voluntary truck emissions recall to date.

    The recall will replace a faulty emissions control systems component that causes excess emissions of nitrogen oxides (NOx). The problem Cummins is acting to correct is the result of a defective part and does not involve a defeat device.

    “Today’s recall is a great example of how government and industry work together to protect health and the environment.” said EPA Office of Air and Radiation Assistant Administrator Bill Wehrum. “This is the way it’s supposed to work. Our follow-up testing seeks to make sure that pollution controls work throughout an engine’s useful life. And, if they don’t, then companies step up to set things right.”

    The trucks being recalled are equipped with selective catalytic reduction (SCR) systems designed to control NOx emissions. NOx is a potent air pollutant that contributes to smog and fine particle formation in the atmosphere. The SCR catalysts that will be replaced through the recall were found to be less durable than is required, degrading within a few years instead of controlling NOx pollution for the regulatory full useful life of the vehicle.

    The recall will replace these SCR system components. The full useful life of medium-duty vehicles is 185,000 miles or 10 years (whichever is first), and the full useful life of heavy-duty vehicles is 435,000 miles or 10 years.

    Medium- and heavy-duty categories include vehicles ranging from larger pickup trucks to vocational vehicles to big rigs. An earlier recall, already underway, involved about 232,000 Dodge Ram 2500 and 3500 pickup trucks, bringing the total number of affected vehicles to about 770,000.

    The problem was discovered through government oversight programs that test vehicles for compliance with emissions standards throughout their useful life. Both EPA and the California Air Resources Board (CARB) run emission testing programs to check emissions from typical, privately-owned vehicles in customer service. Initial testing identified high NOx emissions from certain trucks equipped with Cummins engines. EPA and CARB shared results with Cummins, which agreed to conduct the voluntary recall after the company’s own follow-up testing confirmed that deteriorating components within the SCR system were causing emissions to exceed Federal and California pollution standards.

    Cummins will recall the remaining affected vehicles in two phases. The company will contact owners with instructions about how and when to get their truck repaired. Owners should contact Cummins for further details about the affected products and recall schedule.
