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".

Dodge and Jeep recalling 895k SUVs for possibility of headliner fires

Dodge and Jeep are announcing recalls of a total of 895,000 Durango and Grand Cherokee models worldwide from the 2011 through 2014 model years. There's a possibility that the wiring in the sun visor can short circuit and cause a fire. It specifically affects vehicles built between January 5, 2010, and December 11, 2013, and there are approximately 651,000 of them in the US, 45,700 in Canada, 23,000 in Mexico and 175,000 outside of North America.
Screws that fasten the sunvisor to the headliner may pierce wires in the visor, if the part has been removed or serviced, potentially causing a fire risk. If the wires short circuit, they could overheat and potentially combust. The automakers report three injuries caused by this defect, and according to the investigation by the National Highway Traffic Safety Administration, "there may be a total of 52 unique fire incidents."
To fix the problem, Dodge and Jeep will inspect the vehicles for suspect wiring, and all of the models, whether damaged or not, will get a new sun visor spacer with a wire guide to stop the possibility of short circuits. According to the automakers' announcement, "this condition is not present in vehicles which have not had the headliner or vanity mirror serviced." They will notify affected owners, and repairs will begin in August.
