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.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

164K Jeep Cherokees recalled to protect liftgate from moisture

FCA is recalling 164,003 examples of the 2014 and 2015 Jeep Cherokee because moisture can damage the power liftgate controls on models that are equipped with that feature. Regionally, this includes 99,436 of them in the US, 13,195 in Canada, 2,406 in Mexico, and 48,966 outside of NAFTA. The problem came to light after the automaker started investigating a fire in one of the SUVs. There were no injuries, though. According to FCA US' research, the power hatch's control module potentially can be exposed to water. This can cause a short circuit and possibly a fire, as in this case. Until the issue is repaired, the company is advising owners to keep the cargo area dry on Cherokees equipped with this feature. To fix things, dealers will install a shield around the controls to protect them from moisture and will replace any modules showing exposure to water. Statement: Water-Shield Installation June 24, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 99,436 SUVs in the U.S. to install shields that protect their power liftgate control modules, and related components, from moisture. FCA US LLC began an investigation after learning of a reported vehicle fire. The probe revealed power liftgate control modules in certain SUVs may be inadvertently exposed to water. This may cause a short-circuit, creating a fire hazard. However, the Company is unaware of any related injuries or accidents. The campaign affects model year 2014 and 2015 Jeep Cherokee SUVs, but is limited to vehicles equipped with power liftgates. An estimated 13,195 customers are affected in Canada, along with an estimated 2,406 customers in Mexico and 48,966 outside the NAFTA region. The estimated total recall population is 164,003. All affected customers will be advised when they may schedule service. If the modules show signs of water exposure, they will be replaced. All recall-related work will be performed free of charge. In the interim, the cargo areas of 2014-15 Cherokees equipped with power liftgates should be monitored and kept dry.
