According to the firm's investigation, Dodge has sold hundreds of thousands of Dodge RAM 2500 and 3500 trucks equipped with Cummins diesel engines that release illegally high levels of NOx emissions. The lawsuit outlines a new “comprehensive body of evidence” illustrating findings of two separate emissions-cheating defeat devices that were placed in the affected RAM trucks with Cummins’ and Fiat Chrysler’s knowledge. If you own an affected Dodge RAM, fill out the form to find out your consumer rights to compensation.


The lawsuit outlines the direct collusion between Cummins Inc. and Fiat Chrysler, stating the two “saw a golden business opportunity, and worked together to build a truck that, at least on paper, met these [emissions] standards, three years ahead of schedule.”

The chassis dynamometer testing revealed a defeat device which allowed the vehicles to pass emissions testing during routine testing conditions, but failed during regular driving conditions. Thus, the vehicle performs differently in a certification test environment (on a dynamometer) than in the real world (PEMS testing), which should not be the case.

A secondary defeat device was found which involves one of the vehicles’ primary emissions control after-treatment technologies, the diesel particulate filter. This is where particulate matter (soot) is collected after the exhaust is treated by the diesel oxidation catalyst and NOx adsorber catalyst. The soot captured by the diesel particulate filter is removed from the filter through a process known as regeneration; the regeneration process can be accomplished either by “passive” or “active” means.


Hagens Berman believes that consumers have the right to compensation for the premium price they paid for what they thought was an environmentally friendly diesel option. According to the firm's investigation, Dodge charged consumers high prices for vehicles that in no way uphold its promise of eco-friendly diesel.
