FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

2020 Ram 1500 4x4 Suspension Deep Dive

What is taking everyone so long? That’s what I continually ask myself each time yet another all-new full-size pickup comes out with leaf spring rear suspension. Meanwhile, this 2020 Ram 1500 pickup represents a dozen years since coil spring rear suspension debuted when its prior generation was still being called a Dodge Ram 1500. Ford, Chevrolet, Toyota and Nissan introduced full redesigns of their pickups well after Ram proved that coil springs were the way to go, and yet leaf springs persist with the competition. IÂ’m not just popping off, here. In the 1990s I used to specialize in pickup truck suspension tuning for the Toyota Technical Center. Leaf springs are crude and loaded with compromises, but thatÂ’s all that truck design engineers ever gave us to work with. I was instantly all-in on RamÂ’s move to rear coils after the first few miles of driving a 2009 Ram 1500 pickup. Empty-bed ride comfort and handling were on another level, but it could still tow and haul. In fact, towing stability proved to be frankly incredible on the normally-treacherous downhill leg of my winding tow test grade. I fully expected everyone would copy it immediately. But they didnÂ’t. Others may have doubted the payload aspects. Ram never did. It soon doubled down and put coils under the back of its 2014 2500-series trucks. IÂ’ve developed other theories that seek to explain why no one followed their lead, but theyÂ’re not worth dredging up because I think the dominoes will soon begin to fall. Spy photos suggest that the next Toyota Tundra will switch to coils, and there are rumors that the Ford Raptor is going that way. ThatÂ’s not much of a stretch because the Ranger Raptor (only available outside the U.S.) already has coil spring rear suspension. WhatÂ’s the big deal? LetÂ’s take a look at the underside of a 2020 Ram 1500 Laramie 4x4, the second iteration of the Ram 1500 to employ coil spring rear suspension.   As it has for some time, the front end of the Ram 1500 rides on double wishbone suspension. The truck employs a high-mount upper wishbone (yellow arrow) that positions the upper ball joint up behind the tire sidewall instead of inside the wheelÂ’s barrel. This layout offers improved steering geometry and reduced stress in the upper ball joint, the upper control arm and its mounting points.   Coil-over spring/shock assemblies (green) come standard on all 2019+ (fifth-generation) Ram 1500 pickups whether they have four-wheel drive or not.

Ram recalls 2014-2019 1500 EcoDiesel trucks for coolant leaks

Ram will recall 108,000 Ram 1500 EcoDiesel pickup trucks in the United States for coolant leaks tied to reports of some fires and four minor injuries. Another 50,000 trucks will be recalled in Canada, and fewer than 2,000 sold in markets outside of North America. The recall covers trucks from the 2014 through 2019 model years. The automaker said it found microscopic cracks in some Exhaust Gas Recirculation coolers through dealer-service reports and "other data streams." Such cracks may allow coolant to "escape and – in rare circumstances – pose an engine fire risk." The injuries occurred when customers attempted to manually extinguish engine compartment fires. FCA said it is not aware of any crashes tied to the recall. The automaker will alert owners when they can get recall repairs. Until then customers should monitor coolant levels and contact dealers if they are consistently low. The recall does not affect the redesigned, current-generation Ram 1500, nor any gasoline-powered Ram 1500 from any model year. Customers with questions or concerns may call 1-800-853-1403.
