Duramax emissions cheating scandal
It looks like GM has been using the same cheat techniques as VW did. It affects 705,000 trucks from 2011-2016. I have a 2016. GM is denying it, but they already have the physical and software proof. I...

I work for a Chrysler dealer and have to say it's pretty impressive that all new diesels run so well while producing such a small amount of harmful emissions. These days no late model diesel produces a spec of soot at the tailpipe. The Chrysler Eco diesel gets 27 mpg and has good power. If driven mostly on the highway fuel mileage may be even higher and reliability is acceptable. But if stuck in a city environment they are problematic because of soot problems.
At this point Chrysler for example has no choice...either produce absolutely unreliable engines because they can't run on diesel fuel and capture and store all soot for too long, so they created software that lets the engine breath for a while and hope the customer will get out on a highway where regen can occur and all is well. This methodology worked and the EPA certified them all in 2016. Then the VW situation concluded...
GM, Chrysler, and though we haven't heard of it yet I'm sure Ford will be dragged into this, these companies are victims of the deception VW created. Now the EPA looks at different things these vehicles have to do under certain conditions to try and stay reliable for city driving, and EPA sees it as a cheat. Notice Chrysler said same thing as GM...that they did not knowingly cheat or deceive and they will fight hard to prove it. But not one 2017 eco diesel has passed and been certified for sale by EPA. The VW situation has created pure distrust between all manufacturers and the EPA.
There will be more, Ford, BMW, Nissans new diesel, all of them will be seriously questioned and if you look hard enough you will find red flags with them all. Difference is VW really was deceitful it seems to me. As far as Bosch, well they produce emission parts for all these guys. But they produce them how the manufacturer wants them based on their needs. It would seem easy to blame Bosch but they are building parts as manufacturers require for each engine.
I think EPA needs to ease the emissions requirements for new diesels. Let manufacturers progress smoothly and reach that "as clean as possible level." If they ban every single one, diesels will disappear. As far as the environment is concerned, I personally do care and wish it would stay natural, healthy and pristine. So if you'll ride a horse to work every day then I will too. Well, I guess in that scenario that would mean I have no work...
