Researchers who busted VW cheating say FCA's diesels dirty, too

The Wall Street Journal today reported on an upcoming report from West Virginia University's Center for Alternative Fuels Engines and Emissions, which is the same lab that investigated Volkswagen emissions cheating. The report, which will be released in a matter of weeks, alleges that 2014 and 2015 model year Jeep and Ram vehicles with diesel engines emit excess pollution. But it does not specify whether the company used defeat devices. Since the report discusses Jeep Grand Cherokees, and that engine is also available in the Ram 1500, it's safe to assume that one of the implicated engines is the EcoDiesel V6, a unit actually produced by VM Motori. It's unclear whether the report covers any of the Cummins engines used in heavier-duty Ram pickups. This report comes on the heels of a federal investigation into FCA's diesel vehicles. That investigation focused on the EcoDiesel engine used in 2014-2016 vehicles. The feds were seeking a fine of up to $4.6 billion. The EPA and the State of California also previously accused FCA of using a defeat device on the same vehicles back in January. FCA, for its part, alleges that the WVU study might have been commissioned by people interested in suing the company, and disputes the testing methodology, according to the WSJ. We've reached out to WVU to confirm which engines are implicated in its study and will update this post when we have more to share. Related Video: This content is hosted by a third party.

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.

Daily Driver: Long-Term 2014 Jeep Cherokee

As a fan of the boxy Jeep styling of old, I was disappointed when photos first leaked of Jeep's revived Cherokee in early 2013. Then the midsize crossover arrived in Autoblog's longterm garage in May of 2014 and my opinion did a 180. I was prompted to rethink the exterior design of the vehicle after reading our reviewer's interview with head Jeep designer Mark Allen. "The previous, blocky Cherokee was so aerodynamically inefficient, it would be wrong to do it," Allen told Autoblog's Jonathon Ramsey. That made sense. After all, Jeep is a brand associated with the outdoors, so its only natural that they seek to produce efficient, yet capable vehicles. It was then I began reconsidering the sleek lines of the new Cherokee. What once seemed bland and rounded now appeared streamlined and purpose-built. I also give Jeep credit for the slim headlamp silhouette, which look like no other SUV on the market – a far cry from the distinct circular lamps on Wranglers or squared headlights of past XJs. As I drove our long-term Jeep Cherokee Trailhawk on a few road trips, my affinity for the vehicle's comfortable interior grew as well. The seats held up to a nine-hour trek to Montreal, and the Chrysler Uconnect system made navigating the roads and the radio a breeze. Above you'll hear my early impressions of the Cherokee, and below you'll find a previous long-term update featuring Autoblog's Steven Ewing and Chris McGraw. UPDATE: The video mistakingly indicates that the Jeep Cherokee features LED headlights. The Jeep Cherokee, in fact, has daytime running lamps with LED accent lighting. Related Video:
