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.

NHTSA investigating over 600,000 Ram trucks due to stalling engine

More than 600,000 heavy-duty pickups built by Ram during the 2019 and 2020 model years are the target of a National Highway Traffic Safety Administration (NHTSA) investigation due to a faulty fuel pump. Only trucks powered by the 6.7-liter turbodiesel engine are affected. Documents posted on NHTSA's website explain that the agency's Office of Defects Investigation has received 22 complaints and two field reports claiming that the 6.7-liter turbodiesel straight-six either lost power or stalled completely while driving. The issue potentially affects 604,651 trucks, including the 2500, 3500, 4500, and 5500 variants of Ram's popular pickup. The 1500 model is not included. The agency notes that the high-pressure fuel pump is to blame; stalling occurs when the part fails. It adds that the issue mostly happens above 25 mph, and that the engine can't be started again after it turns off. Interestingly, while the investigation was announced in October 2021, Ram has been looking into it since November 2019. It asked dealers to "collect, monitor, and correct quality issues" on some trucks powered by the 6.7-liter Cummins. It has collected and inspected several pumps as a result of this campaign, according to NHTSA. As of writing, there have been no crashes, fires, injuries, or fatalities linked to the alleged defect. NHTSA officials explained they're looking into "the scope, frequency, root cause, and potential safety-related consequences" of the problem. If the issue is deemed a safety hazard, the agency could ask Ram to recall affected trucks and fix them. Ram said it's complying with investigators but provided no further details.
