Navistar Sued for EGR/SCR Fiasco

EGR and the multiplexed injection make more soot, and that makes for a shorter service interval, which for the block would have been better except every service has a cost. My brother has his DEF tank filled on the pickup at oil changes by the dealer, and DEF at the pump isn't a big deal, you don't need it every time unless the tank is tiny, mine will run over 4k miles.

Weight is a problem, and carrying enough urea as dry and figuring out a way to dose it would have been cost prohibitive, especially when they were never, ever going to go that route, when they were standing behind EGR and multiple pulse injection. It's not that hard to put in DEF at the pump while fueling if needed , and if your company runs out and back, the shop can do it when the truck is home, and since it is just a matter of topping off a tank, you don't need to carry the weight or extra if you run out.

It was a bad decision compounded by other bad decisions to rely on their lawyers and the courts to fix it, they ended up losing the ability to operate producing engines while paying fines because of this.

International, (Navistar), is now at the bottom of the customer satisfaction lists, and many of the companies that were thumbing their noses at DEF are now buying Cascadias and Volvos instead of Prostars.

Cummins stabbed them in the back, so they figured, when Cummins read the same writing everyone else was seeing and decided to abandon an EGR only solution to NOX. So now they are having Cummins design their after treatment, that figures. They are in good company, John Deere resisted SCR and also lost market share because of poorer fuel economy than the competition that embraced it(Case New Holland and AGCO Massey Ferguson).And Caterpillar is now training their technicians to service DEF SCR systems

I think the only ones that made out well dealing with the issue for them were their lawyers, but also it also helped the lawyers for the competition and the competition, while they cheated themselves, their customers, and their stockholders and employees, not to mention the dealers stuck selling those white elephants.
