EPA Announces Largest Voluntary Recall of Medium- and Heavy-Duty Trucks due to faulty pollution controls

WASHINGTON (AP) — An Indiana-based engine-maker is recalling a half-million trucks with faulty pollution controls, the Environmental Protection Agency said Tuesday.

A defective part means pollution controls on the engines wear out more quickly than allowed, the agency said.

The recall affects 2010-2015 medium- and heavy trucks with engines made by Cummins Inc. The trucks range from big pickups to utility trucks to big rigs.

The EPA says emissions testing by the agency and by California discovered the problem.

Cummins agreed to carry out the recall after the company's follow-up testing confirmed that deterioration of the defective part was causing dirtier exhaust than U.S. and California standards allow, the EPA said.

An earlier recall currently underway involved 232,000 Dodge Ram 2500 and 3500 pickup trucks, bringing the total number of affected vehicles to about 770,000.

Editor's Note:  Additional information from EPA

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 ten years (whichever is first), and the full useful life of heavy-duty vehicles is 435,000 miles or ten 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.
