Ram, Jeep 3.0L EcoDiesels Accused of Using Emissions Cheating Software

The U.S. Environmental Protection Agency (EPA) has sent a notice of violation to Fiat Chrysler Automobiles (FCA) advising the company that its 3.0-liter diesel equipped vehicles use illegal software that is meant to fool emissions tests, allowing them to spew an illegal amount of pollutants. 

The EPA alleges that about 100,000 2014-2016 Jeep Grand Cherokee and Ram 1500 vehicles fit with the 3.0-liter EcoDiesel engines have at least eight separate pieces of software that were not disclosed to the agency, meant to change how the engine handles its emissions. The software kicks in under certain operating conditions, allowing the engine to output more than the legal limit of NOx.

Meetings have already taken place on the matter, but so far, FCA has not offered a suitable explanation on why this software was not disclosed to the EPA during the certification process. The EPA is asking Fiat Chrysler to prove why this software is not a defeat device which is intentionally hiding emissions output from testing.

In an official response, Fiat Chrysler says that it is “disappointed that the EPA has chosen to issue a notice of violation with respect to the emissions control technology employed in the company’s 2014-16 model year light duty 3.0-liter diesel engines.” The brand says it “believes that its emission control systems meet the applicable requirements.”

FCA says that is has already proposed a number of actions to address the EPA’s concerns, but so far those action have not been enough to please the regulatory agency. “FCA US looks forward to the opportunity to meet with the EPA’s enforcement division and representatives of the new administration to demonstrate that FCA US’s emissions control strategies are properly justified and thus are not ‘defeat devices’ under applicable regulations and to resolve this matter expeditiously.”

The 3.0-liter diesel engines in question are manufactured by VM Motori, an Italy-based diesel engine maker owned by Fiat. Its ownership history is a little muddled, having been under the control of the former DaimlerChrysler and, at least partially, General Motors at one time or another before Fiat bought the entire company in 2013.

This is only a notice of violation, so all 2016 FCA vehicles fit with EcoDiesels are still for sale. Since the news broke, FCA stock prices have fallen by 16 percent.

    K guess the power hungry E.P.A. needs some more party money.They’re getting out of control.

    their last gasp before being dismantled and having their functions / authority sent back to the states

    why is the current administration sicking the EPA on FCA all of the sudden?

    Didn’t they appreciate FCA being the only one to openly takes sides and support
    the Supreme Court decision on same-sex marriage?

  • Ron

    Over zealous EPA…trying to get their last stabs in before they get flushed.

  • mlebauer

    Should use Cummins in the LD vehicles too. The 2500 and 3500 Ram’s Cummins engine wasn’t cited in the complaint.

  • DoctorFeelgoodMD

    Tip of the iceberg folks!

  • DoctorFeelgoodMD

    So you agree with destroying the planet and making humans sick. People like you are the problem. A huge problem due to lack of education and common sense – typical Trump supporter too I bet. No college degree too I bet!!!

  • Bobbo

    Oh come on. That narrative is so old and trite. Diesels these days are light years ahead of diesels from only a few years ago in both their emissions and there performance. I can’t even smell them any more.

  • DoctorFeelgoodMD

    Diesel engines from many will be caught cheating and I owe one that will be sold back to VW or their multi-billion dollar Dieselgate.
    NOx readings are 20X over the limit and a huge factor in acid rain. Children, people with lung diseases such as asthma, and people who work or exercise outside are particularly susceptible to adverse effects of smog such as damage to lung tissue and reduction in lung function.

    But uneducated people would rather destroy all life as we know it because they have been lied to or too lazy to perform their own due diligence. These people are the ones that know it all or so they believe.

  • Peter Hicks

    ther is a lot said about diesel fuel but what happens if you test a vehile on bio diesel ?

  • djjamsession

    Ron you nailed it.

  • Erik Hoeffner

    Go die EPA

  • Erik Hoeffner

    The world was destroyed when Hiroshima happened. Get over yourself.

  • DoctorFeelgoodMD

    Do you feel better now?

  • Erik Hoeffner

    Feel better about what? You’re an ignorant doc who builds an ego over his college education and is liberal, but is too shallow to realize the world has had pollution and sick humans for 100s of years. I can see that just in what you typed. I’m not gonna argue with arrogance thanks.

  • Erik Hoeffner

    So what are you gonna tell the coal plants from the industrial revolution, or all the smog American Muscle cars from the 70s? Todays diesels and gasoline engines are still cleaner than ever regardless over most major pollutants of the past, and if it wasn’t for you and EPA always having a big irrelevant stick up your ass you’d see none of it matters because the earth is already ridiculously polluted and some countries could give a crap less about the word “pollution” or “smog” even today. Go yuppie cry on your liberal forum while you perscribe ritalin and meth pills to 6-11 year old kids that don’t need it.

  • DoctorFeelgoodMD

    Your rant brings out the worst in you! Most of what you state is incorrect. I’m not even an American Adolf.

  • Mebeingme

    What the EPA isn’t telling you is DEF breaks down the molecules and washes the black smoke before it comes out of the diesel so you can’t see it but the body absorbs molecules easier the smaller they are which in turn causes more heath issues to anyone that breathes it in. Unlike before without DEF the black smoke that comes out the body has a harder time absorbing it because the molecules are bigger. Not to mention running DEF on these new trucks causes worse mileage more maintenance and pricey parts to keep them running. The EPA is trying to save the world but causing more harm to humans and costing consumers more money. Just think trucks using DEF get on avg. 5 mpg less and a factory produces DEF put’s it in plastic containers and ship it around the county please explain how burning more fuel and producing another fluid / adding trucking costs helps anyone but the oil industry … EPA & Big Oil are thick as thieves

  • Mario

    Are you dumb?

  • Then why do you care? If you’re not an American, these EPA rules and tests are not relevant to you.

  • DoctorFeelgoodMD

    I have resided in the US for 25 years now and own a VW TDI. So, yes, I’m involved heavily compared to most of you. Besides, you should have figured it out. Likely a Trumpster too.

  • Safron

    This won’t be an issue once Trump gets ride of the EPA.
