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.

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.

The Jeep Grand Cherokee Trackhawk is pretty much good to go

We've been stalking the Jeep Grand Cherokee Trackhawk for months, and now we're getting our best look yet at the devilishly powerful sport utility vehicle. From a distance, the JGC looks almost stately in black. Look closer and you see the SRT badges and the big brakes. Look past the wrappings and you see large air intakes in the lower fascia. All of this reinforces the Trackhawk's performance pedigree, which will be anchored with the 6.2-liter supercharged Hemi Hellcat V8. It's rated at 707 horsepower in the Charger and Challenger Hellcats. The Jeep will use four-wheel drive. These up-close images show off the Trackhawk's simple design. Like the Dodge Hellcats, Jeep appears to be letting the power and capability stand on their own. Previously, we've only seen the Trackhawk from a distance or in blurry video. The Trackhawk's arrival comes as Fiat Chrysler expands Jeep's global presence. The company is increasingly looking to its venerable off-road brand for sales volume, image building, and profits as it re-aligns its car business and looks for potential partners. The Trackhawk looks nearly production ready, and we expect it to go on sale in 2017. Also, don't confuse it with the Trailhawk, which is a trim level you can buy on the 2017 Grand Cherokee.
