A fuel pump is to blame.
The human race has been building cars for well over a century, and while cars such as the Toyota Camry and Honda Civic have come close to perfect reliability, we're yet to build the indestructible car, and on that journey, there will be casualties. Mass recalls are still as prevalent today as ever, partly thanks to the introduction of more complicated technology, but sometimes all it takes is something as simple as a high-pressure fuel pump to force the recall of over 200,000 cars. That's exactly what's happening with RAM at the moment. Stellantis will be recalling 222,410 Ram Heavy Duty and Chassis Cab trucks built between 2019 and 2020 for faulty fuel pumps after an investigation revealed that this rudimentary part was causing stalling issues on the 6.7-liter Cummins diesel engine.
In October, the National Highway Traffic Safety Administration (NHTSA) was investigating reports by owners of the Ram 2500 and Ram 3500, as well as their larger 4500 and 5500 siblings, that their vehicles would occasionally stall and fail to start back up again. The investigation revealed that a defective high-pressure fuel pump was at fault, triggering the large-scale recall.
Stellantis eventually released a statement saying that it had "discovered the components are subject to inadvertent wear that may contaminate their mechanisms with metal shavings." The company then said that "if this occurs, it may cause the vehicles to stall or prevent them from starting." The company says that it is unaware of any accidents or injuries caused by the faulty high-pressure fuel pumps, and that it had already conducted its own investigation before that of the NHTSA.
According to the NHTSA, the issue reveals itself when the affected trucks travel at more than 25 mph. This would "result in permanent disablement of the vehicle." At the time the report went live on 14 October, there were 22 reports of the problem. Symptoms of the issue could also include "a fuel leak, abnormal engine noise, or a change in drive quality." Abovementioned trucks built between October 11, 2018, and 13 November, 2020 have been affected. For more details, owners can call Stellantis at 800-853-1403 or visit NHTSA's recalls site. As always, the affected part will be replaced with a revised unit free of charge.
