** I do NOT work directly for Cummins, rather I work at a fully certified Cummins shop and these are simply my Educated Opinions based upon Publicly available sources and information **

I review this RAM 2500 Cummins Diesel engine and explained the Emission Recall as a certified Cummins Mechanic. I go over the pros and cons of this 67A emission recall. I discuss important factors like how certain Cummins diesel engines will not need to be recalled. I also discuss what I think is going to happen to these Cummins engines after the emission recall including power loss, fuel economy and emission related issues. Lastly I discuss the mitigation that Cummins has agree to pay totaling almost 2 billion dollars in fines.

on January 10th this agreement was agreed upon between cummins and the EPA. there is some great information that I wanted to share.

firstly the 2019-2023 ram cummins diesel trucks will NOT be getting recalled. this is great news. the reason why they were included in the first place is because of failure to disclose emission software to the EPA. but thankfully these engines were fully emission complient resulting in no recalls needed.

Secondly we found out that the 2013-2018 trucks did indeed fully have defeat device software in them. this software was used to make sure the when the trucks were getting emission tests they ran clean but during normal driving conditions the truck would be emitting too many nox gases.

People are saying that after the recall these trucks are using more deisel exhaust fluid or DEF which makes sense. I think what cummins is going is runing more EGR gases through the engine to limit emissions.

I think over the long run we will see more fuel being burnt because of more frequent regens. These engines will run more sooty and this cause more EGR coolers and EGR valves to fail. Thankfully cummins is going to extent warranty on these emissions but it will be interesting to see long terms results on power and fuel economy on those cummins diesel engines.

lastly is the mitigation that Cummins has agreed to. worth around 325 million dollars. they will pay california 175 million and replace 27 locomotive engines with clean diesels or electric engines.

let me know what you guys think!
