2017 Jeep and Ram EcoDiesels Are Legal Again, Baby!

2017 jeep and ram ecodiesels are legal again baby

The light-duty Chrysler diesel is back. After a bevy of undeclared emissions control devices sank Fiat Chrysler Automobiles into a cauldron of hot water back in January, U.S. regulators have certified 2017 models powered by the company’s 3.0-liter EcoDiesel V6.

Having spent the last half-year cooling their heels, unsold Ram 1500 and Jeep Grand Cherokee oil-burners are once again legal for sale to torque- and economy-obsessed buyers.

FCA earned itself plenty of bad PR after the Environmental Protection Agency all but accused the automaker of a Volkswagen-like scheme to deceive the U.S. government and cheat on emissions tests. The undeclared software amounted to a violation of the Holy Grail of environmental legislation: the Clean Air Act. Software tweaks have now rendered the engine compliant, earning a certificate of conformity (also known as a thumbs up) from the EPA.

Too bad about that Justice Department lawsuit.

“The approvals announced today represent a significant step toward resolving the issues raised by EPA and ARB”, said Fiat Chrysler CEO Sergio Marchionne in a release. “We appreciate the efforts of the agencies in working with us to achieve this milestone. We are anxious to build on this progress to make appropriate updates to the emissions control software in our earlier model year vehicles.”

EcoDiesel engines found their way into roughly 104,000 Rams and Jeeps from model years 2014 to 2016. The automaker previously said that a fix will be made available to existing owners.

“The 2017 updates include modified emissions software calibrations, with no required hardware changes,” stated FCA in a media release, “and FCA US expects that the modified calibrations will have no effect on the stated fuel economy or the performance of these vehicles.”

FCA filed a certification application for the reworked EcoDiesel back in May. Unfortunately for the automaker, it wasn’t enough to stave off a lawsuit from the Justice Department. The automaker faced a potential for billions in fines, though it isn’t known yet how the certification of 2017 models — and the potential for an older-model fix — will impact the case.

    From what I can tell, the cheat software would prevent or delay "regen" mode, under extreme operating conditions, to greatly reduce the chances of a damaged engine, turbo or emissions equipment.

    I recently traded in my 2016 Ram 1500 diesel. It was re-flashed by the dealer at the 10,000 mile oil change. The mileage for my commute went from 30 to 22-23. Still a great truck but not the same vehicle I bought. I bought a 2017 GTI SE for half the price and I am enjoying it just as much. I love diesels and trucks but I spend a lot of time in downtown Austin and don't miss trying to parl a full-sized truck.

      So what you're saying, rreichar, is that the full-sized truck was too big for your needs. Right?

  • THX1136 I have the vague notion that the crude out of Venezuela is of poor quality and more expensive to refine. Did I dream that or is it true? Maybe I'm thinking of Canada.
  • THX1136 Matt: Wyoming is not necessarily 'brutally' cold in the winter. It has roughly the same temps in the state as that of Iowa and southern Minnesota. Yeah, it can get cold - and northern Wyoming is more akin to N. Dakota - but not super cold in much of the state. My son lives in Cheyenne - southern part of the state - and he experiences temps roughly the same as here in central Iowa where I live.When I was commuting to work (45 mi.one way to Des Moines), I would see mostly Priuses (Pri-eye) and very few other EV related cars - the odd Volt (1-2) and Tesla (2-3). There may be more as I am not totally up on all the EVs that may be around me and I rarely drove into the downtown area where more may be present.
  • Syke Congratulations on not mentioning the political possibility. I'm sure that during the reading of the article, I'm not the only one noticing the states primarily listed are primarily considered conservative states. And they're not all states bordering Canada.
