Cummins and EPA Agree to Expand Faulty Part Recall


In the name of protecting customers and the environment, Cummins and the EPA have decided to expand a previous recall to include close to 500,000 trucks equipped with the Cummins turbo-diesel 6.7-liter six-cylinder produced between 2010 and 2015.

According to Reuters, the recall was initiated due to a problematic part in the exhaust system that can clog with nitrogen oxide and trap it prematurely. The issue is a connector that can corrode and rust, affecting the catalytic converter in the exhaust system. The EPA said the problem is not similar to the software defeat system discovered in some Volkswagen models in order to pass U.S. emissions testing.

Cummins will roll out the voluntary recall this month, starting with Ram 2500, 3500 and chassis-cab models, with medium-duty trucks beginning next March. The fix involves replacing the old catalytic converter with a new, stronger catalytic converter — which may be pricy for some of those older heavy-duty Rams, but will be covered at no cost to owners. photo by Mark Williams
