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".

2019 Dodge Durango raids the SRT parts bin for updates

Fiat Chrysler will squeeze some extra excitement from the upcoming 2019 Dodge Durango, by providing some modest updates. They include giving the three-row SUV new colors and broadening the use of elements of the Durango R/T and SRT performance models, among other upgrades when it goes on sale in the fall. It'll still be offered in five models — SXT, GT, Citadel, R/T and the SRT — with the same 295-horsepower 3.6-liter V6 as the standard engine. For 2019, the GT model will get the SRT and R/T's performance front fascia and LED fog lamps. It also has the option of an SRT-inspired hood with center air inlet duct and two heat extractors. On the Citadel models, second-row captain's chairs will be standard. There's also a new integrated trailer brake on models equipped with the Trailer Tow Package. New 20-inch wheel designs are available on various trims, and an available 825-watt, 19-speaker Harman Kardon sound system for the Citadel, R/T and SRT. Three new exterior color options appear, too: F8 Green, Destroyer Gray and Reactor Blue. SRT buyers can now opt for red seat belts and lightweight Brembo brakes with two-piece rotors. Its Hemi V8 still makes 475 horsepower as it did last year. The R/T model, meanwhile, continues with the 5.7-liter Hemi V8, also available on the Citadel, making 360 horsepower and 390 pound-feet of torque. Sepia leather seats are a new option. Order books are now open, but there's no word yet on price. Related Video:

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.
