August 2, 2018—Engine maker Cummins Inc. announced it will voluntarily recall 500,000 model-year 2010-15 medium- and heavy-duty trucks to replace a defective catalyst in the emissions control system, Transport Topics reports.

The campaign is the largest voluntary recall of medium- and heavy-duty trucks ever, according to the U.S. Environmental Protection Agency.

This comes after a recall begun in 2016 of 232,000 Dodge Ram 2500 and 3500 vehicles with pre-2013 Cummins engines. Recalls for those vehicles were approved in July 2016 and July 2017, respectively, and are underway. Those vehicles and the latest medium- and heavy-duty trucks all produce excessive amounts of smog-forming nitrogen oxide.
