NHTSA Investigating Ram's Diesel Pickups

The National Highway Traffic Safety Administration has opened an investigation into nearly 605,000 heavy-duty Ram trucks. A report from the regulator’s Office of Defects Investigation has tabulated 22 complaints from the 2019 and 2020 model years, all of which use 6.7-liter Cummins turbo diesel engines, spurring the NHTSA to launch a formal investigation. Complaints revolve around loss of motive power, with most incidents occurring above 25 mph and resulting in the “permanent disablement of the vehicle.”

While the public was not made aware of the investigation until Monday, the agency launched its probe last Thursday on October 14th. The goal will be to establish how widespread the presumed defect is, what exactly caused it, and any potential safety hazards relating to the issue. Some headway has already been made, however.

Back in 2019, Fiat Chrysler Automobiles (now Stellantis) issued Warranty Bulletin D-19-02 to dealers. The memo requested stores participate in a campaign to “collect, monitor and correct quality issues” on certain MY 2018-2020 Ram trucks equipped with the 6.7-liter Cummins. The NHTSA’s action summary states that this resulted in FCA and an unnamed supplier collecting and inspecting high-pressure fuel pumps.

Vehicles under suspicion include all Ram 2500, 3500, 4500, and 5500 HD pickups from the 2019-2020 MY. The NHTSA plans on looking into the trucks to determine whether or not it needs to press Stellantis to launch a recall. That means asking the manufacturer to give its take on the situation while it compiles warranty claims, injury reports, and whatever FCA previously had on those suspect fuel pumps.

Regulators have been incredibly hard on diesel vehicles ever since Volkswagen’s emissions scandal upended the industry in 2015. While a part of me wants to believe the NHTSA just has it out for Ram’s HD lineup (since a few have asked), it seems far more plausible that this was a standard, shrug-your-shoulders defect. Selective environmental regulations have made diesels cost more as they’ve gradually amassed a bevy of pollutant controlling hardware while also complicating powertrains to a point that has lessened their overall effectiveness. But the impact this has had on their reliability is less obvious and may have nothing to do with a bunch of subpar fuel pumps.

Let’s face it, U.S. regulators haven’t been shy about hitting manufacturers with emissions-focused recalls backed by the Environmental Protection Agency and/or California Air Resources Board in the past. If they wanted to chide Cummins or FCA/Stellantis over pollution, they could have done so overtly.

Stellantis has said it plans on cooperating with the NHTSA fully, launching an investigation of its own for good measure. So we should have some answers soon, including the name of the supplier. In the meantime, you might want to keep a closer eye on how your HD Ram is running if it falls under the purview of the investigation.

He later found himself driving box trucks through Manhattan, guaranteeing future sympathy for actual truckers. He continues to conduct research pertaining to the automotive sector as an independent contractor and has since moved back to his native Michigan, closer to where the cars are born. A contrarian, Matt claims to prefer understeer — stating that front and all-wheel drive vehicles cater best to his driving style.

  • JK I grew up with Dodge trucks in the US, and now live in Turin, Italy, the home of Fiat. I don't think Italians view this as an Italian company either. There are constant news articles and protests about how stalantis is moving operations out of Italy. Jeep is strangely popular here though. I think last time I looked at stelantis's numbers, Jeep was the only thing saving them from big big problems.
  • Bd2 Oh yeah, funny how Trumpers (much less the Orange Con, himself) are perfectly willing to throw away the Constitution...
  • Bd2 Geeze, Anal sure likes to spread his drivelA huge problem was Fisher and his wife - who overspent when they were flush with cash and repeatedly did things ad hoc and didn't listen to their employees (who had more experience when it came to auto manufacturing, engineering, etc).
  • Tassos My Colleague Mike B bought one of these (the 300 SEL, same champagne color) new around June 1990. I thought he paid $50k originally but recently he told me it was $62k. At that time my Accord 1990 Coupe LX cost new, all included, $15k. So today the same car means $150k for the S class and $35k-40k for the Accord. So those %0 or 62k , these were NOT worthless, Idiot Joe Biden devalued dollars, so he paid AN ARM AND A LEG. And he babied the car, he really loved it, despite its very weak I6 engine with a mere 177 HP and 188 LBFT, and kept it forever. By the time he asked me to drive it (to take him to the dealer because his worthless POS Buick Rainier "SUV" needed expensive repairs (yes, it was a cheap Buick but he had to shell out thousands), the car needed a lot of suspension work, it drove like an awful clunker. He ended up donating it after 30 years or so. THIS POS is no different, and much older. Its CHEAPSKATE owner should ALSO donate it to charity instead of trying to make a few measly bucks off its CARCASS. Pathetic!
  • RHD The re-paint looks like it was done with a four-inch paintbrush. As far as VWs go, it's a rebadged Seat... which is still kind of a VW, made in Mexico from a Complete Knock-Down kit. 28 years in Mexico being driven like a flogged mule while wearing that ridiculous rear spoiler is a tough life, but it has actually survived... It's unique (to us), weird, funky (very funky), and certainly not worth over five grand plus the headaches of trying to get it across the border and registered at the local DMV.
