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.

2019 Ram 1500 eTorque Drivers' Notes Review | Filling in the gaps

When the 2019 Ram 1500 debuted earlier this year at the 2018 Detroit Auto Show, the biggest news was arguably the addition of the 48-volt mild hybrid system. Dubbed eTorque, the system is standard on V6-equipped models and a $1,450 option on trucks with the 5.7-liter Hemi V8. It's not a hybrid in the traditional sense. Despite Ram's claim that the system adds up to 130 pound-feet of torque on the V8, it only does so for a fraction of a second and doesn't actually change the engine's total output. You'd be hard pressed to notice a difference if you didn't know the system was there. But that's kind of the point. There's been a lot of confusion about what eTorque is and how the system works. Much of that falls on FCA's shoulders. The automaker didn't do a great job of explaining the whole thing, leaving us to work out much of it for ourselves. This isn't meant to boost performance, towing or payload. The Ram eTorque can't run on battery power, so don't expect a Toyota Prius with a bed and wood trim. It's here to make the truck just a little bit more efficient by improving areas where conventional internal-combustion engine's fall short. The eTorque system replaces the engine's alternator with a small, belt-driven electric motor. On the V6, the motor is part of the water pump assembly and driven by that belt; the V8 uses a dedicated belt that's separate from the other accessories. A small battery pack is mounted upright behind the rear seats inside the truck's cabin. There's also a DC-to-DC converter to charge the battery and convert 48 volts down to 12 to power the truck's normal systems. Visually, the only difference between an eTorque-equipped model and a standard one is a small metal box at the top of the engine. There's no badging and the battery pack can't be seen, even with the rear seats folded up. The system is designed to be as seamless and innocuous as possible. The auto start/stop system spins up the engine a little quicker. Shifts from the eight-speed ZF automatic transmission are a little smoother as the eTorque system smooths out and fills in the gaps. It does so for a fraction of a second, but it works its magic often. Big gains in fuel economy have already been made. It's going to take things like Ram's eTorque system to improve internal combustion engines from here on out. Editor-in-Chief Greg Migliore: I'd like to say I noticed a huge difference between the Ram eTorque and the regular Ram, but I didn't. That's how it's supposed to work.

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.
