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.

Fiat Chrysler recalls 650,000 Dodge, Jeep SUVs for brake issue

Fiat Chrysler Automobiles said Tuesday it's voluntarily recalling nearly 650,000 Jeep Grand Cherokee and Dodge Durango SUVs to ensure that brake-booster shields were properly installed. The recall affects mostly vehicles sold in the U.S. but also roughly 60,000 combined in Canada and Mexico. The shields were installed in 2014 in conjunction with a recall involving the same set of vehicles, which cover the model years 2011 through 2014. A review of warranty data led to an FCA U.S. investigation that discovered the problem. FCA says it is aware of one potentially related accident, but no injuries. The shields are designed to keep water away from the boosters, lest it cause corrosion or freeze in cold temperatures and negatively affect brake performance. Brakes will still function even if boosters are compromised by water, FCA says, but drivers may experience brake-pedal firmness. In some cases, a potential booster issue may trigger a warning light or activation of the anti-lock brakes. Customers who've observed any of those conditions are urged to contact their dealers. The automaker says it plans to notify affected owners that free service to check and repair the issue if necessary will be available in early November.
