100,000 Jeep Cherokee models subject to further 9-speed recalibration

It seems that the software problems with the nine-speed automatic gearbox in the Jeep Cherokee continue to mount. The programming already caused multiple development delays and even postponed the Cherokee's market launch by roughly two months. Now, Jeep has issued another recalibration to hopefully assuage unhappy drivers.
According to Automotive News, this reflash for the allegedly jerky transmission covers over 100,000 Cherokees built before May 5, but it's not technically a recall. If owners are having problems and complain to the dealer, they get the new software. Otherwise, they continue with the current version. New vehicles on dealer lots also receive the latest revision to the programming. It takes only around five minutes to install, but technicians need to take the Cherokee on a test drive to adapt the gearbox to the changes.
The Cherokee's transmission software has been problematic practically since the beginning. The Jeep plant in Toledo, OH, briefly idled its second-shift workers last year to take care of the issue. Since the launch issues for the crossover, demand has been strong. Jeep added another 1,000 temporary workers to the Toledo factory to keep up, and sales were on par with the Wrangler in just its first two months.

Fiat Chrysler working on an inline-six to replace the Pentastar V6?

Get out your Skeptics Hat for this one and keep it close by. Allpar cites "reliable sources" to write that Fiat Chrysler appears to be working on a new inline-six engine to be slotted into company products around the globe. The purported engine would be based on the 2.0-liter Global Medium Engine inline-four. Allpar first reported on the potential development in February 2017 and has filed a few updates since then, one citing "internal communications referring to a GME T6" — the "T" meaning turbocharged. It's said that some engineers have changed their online resumes to reflect their focus on the new motor. Apparently, FCA tried adding forced induction to the Pentastar V6 but didn't like the results. The new direction then turned toward a "compact straight-six." In at least one guise, the GME I-6 would come in at just under three liters in order to escape taxes on engines 3.0-liters and above in certain European markets; the 2.0-liter four-cylinder has an actual displacement of 1.995 liters. The present V6 Pentastar comes in 3.2-liter and 3.6-liter guises; a turbocharged 3.0-liter straight-six should be able to replace both as far as output. Hooking up to the company's eTorque system used on the 3.6-liter Pentastar and 5.7-liter Hemi would make things even more punchy. With the trend in truck engine downsizing, it wouldn't be crazy to see such an engine head straight to Ram. The four-cylinder GME unit serves in the Alfa Romeo Giulia and Stelvio, and Jeep Cherokee, Wrangler, and Grand Commander. The big Alfa Romeos and full-size Jeep and Ram models shouldn't have any problem with a longer inline engine. Maserati, which doesn't use the Pentastar engine, could be a candidate as well should it choose to step away from its Ferrari-developed engine cred. Speaking of Ferrari, the Italian brand is working up a new V6 based, in its words, on "a very, very particular architecture." It isn't clear where it will go or if one of the other Italian brands will get access to it, but the Allpar piece says the Ferrari V6 will be based on the core GME architecture for Maserati. Chrysler gave up its last inline-six 11 years ago when the 4.0-liter I-6 retired alongside the JK-series Jeep Wrangler. The engine format is back in vogue, and its reincarnations have received good reviews. But inline-sixes are generally longer, hence FCA's focus on a compact unit, and that could limit the purported engine's placement options.

EPA suspected Fiat Chrysler of using 'defeat device' in 2015

U.S. regulators told Fiat Chrysler Automobiles in November 2015 that they suspected some of the automaker's vehicles were equipped with secret software allowing them to violate emission control standards, according to emails disclosed on Friday. The U.S. Environmental Protection Agency and California Air Resources Board accused Fiat Chrysler in January of using the software, known as a "defeat device," to illegally allow excess diesel emissions in 104,000 Jeep Grand Cherokees and Dodge Ram 1500 trucks built between 2014 and 2016. Byron Bunker, director of the EPA's Transportation and Air Quality compliance division, said in a January 2016 email to Fiat Chrysler, obtained by Reuters under the Freedom of Information Act, that he was "very concerned about the unacceptably slow pace" of the automaker's efforts to explain high nitrogen oxide emissions from some of its vehicles. Nitrogen oxide is linked to smog formation and respiratory problems. Bunker's email said the EPA had told Fiat Chrysler officials at a November 2015 meeting that at least one auxiliary emissions control device on the car maker's vehicles appeared to violate the agency's regulations. Mike Dahl, head of vehicle safety and regulatory compliance for Fiat Chrysler's U.S. unit, responded in a separate email that the company was working diligently and understood the EPA's concerns. He added that if the EPA identified Fiat Chrysler vehicles as containing defeat devices it would result in "potentially significant regulatory and commercial consequences." The documents redacted the vehicles named, but two officials briefed on the matter said they referred to diesel models. The EPA's November 2015 meeting with Fiat Chrysler came two months after Volkswagen AG, mired in a major tailpipe emissions scandal, admitted to installing secret defeat device software in hundreds of thousands of U.S. diesel cars to make them appear cleaner than they were on the road.
