Lawsuit Accuses GM of Cheating on Diesel Emissions

IMG_3549a II

A class-action lawsuit filed last week accuses GM, maker of the 6.6-liter V-8 Duramax turbo-diesel engine, of intentionally trying to evade emissions requirements. The suit claims that the engine used in the Chevrolet Silverado and GMC Sierra heavy-duty pickup trucks emits two to five times more nitrogen oxide than legally allowed by the EPA.

According to The Detroit News, the plaintiffs in this lawsuit will be represented by the same law firm that brought suit against the Volkswagen Group for the discovery of an emissions defeat device in its diesel engine computer controls. That suit resulted in VW setting aside billions of dollars for fines and penalties, including buybacks. The Detroit News also reported that pickups involved in the suit are model-year 2011 through 2016; almost 705,000 three-quarter-ton and one-ton pickups have the engine in question.

GM has issued a statement denying these charges, whereas Bosch (the supplier of the emissions system) declined to comment on any issues related to pending litigation.

The emissions defeat device discovered in the VW case, according to federal regulators, involved Bosch software capable of recognizing emissions testing in a lab or smog station and adjusting emissions accordingly, while a different set of emissions parameters were used when on the road. This allowed VW diesels to avoid using costly urea-injection methods to keep emissions levels within legal limits in all driving scenarios. Interestingly, the Duramax engine in the GM case uses the complicated urea injection system in the exhaust stream to reduce NO2 levels emitted through the tailpipe.

Fiat Chrysler Automobiles also is accused of cheating on diesel emissions in 100,000 diesel-equipped vehicles (mostly Ram 1500 pickups and Jeep Grand Cherokees SUVs equipped with the 3.0-liter V-6 EcoDiesel). German carmaker Mercedes-Benz, also embroiled in similar accusations, has decided not to seek certification for 2017 diesel models to be sold in the U.S.

Wow! The hits just keep happening.
Shakes that can't be solved, declining market share. RAM beating Chevy month after month.
Fleet pricing every day and still no traction. Ignition switch lawsuit. FORD 2 trucks about to eclipse GM' six truck strategy . Now allegations of diesel cheating. Really sucks to be them right now.

R.I.P.

Ford is next to be hit hard!

Busted. You can crown Ford as the winner of all the diesel shootouts now. GM has been disqualified for using illegal engines.

Ford is next to be hit hard!

Get off your knees, and stop praying. LOL

Funny how pickuptrucks.com didn't report the DOJ lawsuit announced last week against Ram for their diesel emission issues!!!

cheaters!!!!!!!!

Man, auto companies are just full of scandals these days. Lol

I hate you Government Motors , what did you have to fallow fiat trucks path, you should fallow FORD'S path. We're doomed!!!!!!

Only accuses, let see some facts.

GM's response:


It's Izusu's fault. We didn't design the Duramax, remember.

This whole thing is a shakedown by this law firm. It's a class action lawsuit by a total of TWO 'owners' by the same law firm suing FCA, on the eco diesel, Mercedes for diesel, VW for Diesel and Ford over the GT350 brakes.

http://www.npr.org/sections/thetwo-way/2017/05/26/530221853/lawsuit-claims-gm-used-defeat-devices-on-duramax-diesel-trucks-and-suvs

Bosch needs to go down, and I mean down and out of business for developing the software. To bad car manufactures cannot design and build there own crap. About everything on a car is farmed out to another company.
Kind of like the Taco frames, still farmed out to the same company from back in the early 2001's and still rusting out.

LOVE
FORD!

This whole thing is a shakedown by this law firm

@Jack

Bravo. Absolutely correct. Just like the big lawsuit that took 40 billion dollars from the tobacco industry a few years ago.

The victims? They're dead. The lawyers?

They're rich beyond their wildest dreams.

Hate to break it to all you ford humpers out there, the powernope is next. This lawsuit is going after all diesels in the US because the EPA's requirements are beyond realistically achievable.

Personally I think that the EPA is just another corrupt institution that is trying it best to destroy the auto industry by imposing restrictions that are unobtainable and making the price of vehicles to increase dramatically.

@ME never have truer words been spoken. If people only new half the hoops these manufactors go through. The epa has their boot on the neck of the auto manufactors. Poor people who sacrifice a nice car for a prius get punished twice. Now that the state and feds aren't getting their taxes from the fuel because were using less they hit them with a special tax. WTF?

HAHAHAHA!!!..I can just see the usual shaky GOVT motor fangirls going..."oh noooo!!!...not again!!!"...wonder what lame excuses they're come up with this time :-))

But putting all excuses on the side, this is actually bad news for us tax payers; we cannot afford another shaky GOVT motor bailout as they haven't even paid back the last one....

Geez, it sucks to be a cheby fanygirl right now :-((

The leaner they run under hard use the hotter the exhaust becomes causing a rise in NOx. It's also where the motor is making its best power and is most efficient. I can see why they want to get as close to that line as possible, though the penalty for crossing it is becoming quite expensive. It may be the reason Fords 6.7 is a bit less fuel efficient, they didn't want to push the NOx boundaries too far.

@lionel. Damn you ford whores are the worst. Are you really so ignorant that you don't think that the powernope won't have this happen? If so, you need to take off your rose colored lenses. There's a reason the likes of BMW, Mercedes etc don't offer that many diesels in the US. It's because the requirements are so strict you either don't offfer anything or cheat to pass. The HD diesel market is too lucrative for all brands to pick option #1, so they fake it until they make it ( or get caught). My prediction is that if the EPA maintains their increasingly stringent requirements, diesels may die or become significantly more underpowered than they can be.

KEEP WINING AWARDS FOR THAT. GARBAGE MOTORS SUCKS.

Oh and another thing that's why I stick with the best FORD AND ONLY FORD. KEEP CRYING RIVERS GARBAGE MOTORS FAN GIRLYS. HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH.

So the same lawyers will do gm ,Ford ,dodge, ,etc,,

@Trucky48 or whatever name you're hidding under;

Ford was not even mentioned in the article you dumb $hit but shaky GOVT motors along with the others...OK!!!....now go back to your corner to cry...wow what a bunch of cry babies these cheby fangirls :-))

GM has issued a statement denying these charges,...

GM said it, I believe it, nuff said....O.k. Ford fan girls, back to pushing your Fords around the driveway.

Amazes me how many fall for this and think it is a bad thing. I hope everyone realizes all diesel manufacturers are going to face the same B.S allegations.

Maybe. Maybe not.

I'll be curious to see what comes out of this. If there is indeed software that alters the emissions profile when conditions fall outside of test parameters, they're up as stinky a creek as VW.

The allegations are curious.

At the same time (IANAL disclaimer), I am having a terrible time figuring out what the tort is here.

Apparently, it's that GM lied to them, but they haven't suffered materially from the lie. And, to the contrary, they stand to take a serious hit if GM is forced to re-mediate these engines and sap their power/resale/fuel efficiency.

The test protocol is a 20 minute test that is run once when hot and once when cold, but at the same time, the parameters of the test are such that a defeat device could be programmed to identify operating conditions that are outside of the test parameters.

Frankly, GM did do something a bit unconventional with how they setup the Duramax diesels, and--as with Navistar and VW, they may have discovered that compliance was impossible after they committed to that design.

I'm not saying these lawyers are doing anything other than looking after their own wallets, but that doesn't necessarily mean they didn't stumble across a legitimate bit of subterfuge.

It said GM used at least three "defeat devices" to ensure that the trucks would meet federal and state emission standards, even if they generated more pollution in real-world driving.

No surprise here, after the key event, people are no longer trusting GM, expect them to continue to slide over facts such as this.

According to GovMsRGreat (the GM version of Hemigoon) this is GREAT news. All publicity is good publicity. This is just a Class action suite. The findings are what will matter. In all likelihood GM will probably buy their way out of this with a settlement which is easy for them as they still have all that gifted socialist taxpayer money.

Love how you ford muppets continue to prove my point. Your rose colored lenses must be permanently affixed, as your unmatched ignorance continues to uncannily present itself.

Practice what you preach, dufuq0uttahere

Hey where is johnny dum dum?

Probably just some money grabbing law firm but doesnt look good for GM. If this escalates even more, Ram will permamently overtake Chevy.

@tailhook

Not likely. Until RAM has a mid size model they'll be in third place behind GM and Ford.

It seems really hard to believe GM would be this dumb after the VW scandal. . . . . .

It seems really hard to believe GM would be this dumb after the VW scandal. . . . . .

We all knew VW couldn't be the only one. The only mystery is who else? how much? and whats the penalty? Fiat and GM seem to have gotten their heads up onto this block. But hey if you can excuse them for being deadbeat welfare failures a little cheating wont bother you at all either.

"Not likely. Until RAM has a mid size model they'll be in third place behind GM and Ford."

TO PAPAJIM: Ram isn't in third place because they lack a mid-size truck. They at one time had a mid-sizer along with GM, Ford, Nissan and Toyota, and still were third on the back of the Ram full-sizers. They would still (probably) be third today if the Dakota were for sale. They don't have GM's capacity or the Tacoma's cachet, which is why their next mid-size pickup is going to be Jeep-based.

The diesel market is tough to be in , it has had to overcome many obstacles in the emissions world . I'm not cutting on any particular company, but it is achievable. Deere , cnh, Cummins, Isuzu, yanmar .... and the list goes on have all spent millions in r&d to get it to work . I'm not arguing the epa is bullzhit , but it can be done . Def is not a bad thing it's not complicated, but it's something you people obviously know nothing about .... so before you want and rave about something to the public you know nothing about do some research !!!!! I don't care which manufacture did it if you accept a ecu payload that intentionally does this to pass emissions you should go down .... gm maybe didn't right the software but they accepted it as did vw ! So quit your dumb add comments about something you obviously know nothing about and do some research instead .... half you people probably don't know the pros and cons to owning a diesel or you have one but really don't know why , other than you can tell people ... ( I have a diesel) whatever

This is why we can't have nice things.

This is why we can't have nice things.

(RAM lacks) GM's capacity...which is why their next mid-size pickup is going to be Jeep-based.

@surely yew jest

RAM is a brand just like Jeep is a brand---they're both owned by Fiat. Mfg capacity has almost NOTHING to do with it. If RAM wants to compete at a higher level, they must bring a mid size to market. Ford is doing it. By 2020 every major producer will have a mid size truck in the market.

RAM (or Jeep) cannot afford to lag behind any longer. It's been damn near 10 years since they killed the Dakota.

Man, auto companies are just full of scandals these days. Lol
