Stellantis will replace high-pressure fuel pumps in more than 200,000 trucks after an investigation into stalling in trucks with the 6.7-liter Cummins diesel engine.

Stellantis, parent company of Ram, has announced it will recall about 222,410 U.S. Ram HD and Chassis Cab trucks from 2019–2020. The recall is to replace fuel pumps in trucks with the 6.7-liter Cummins diesel engine.

In October, it was revealed that the National Highway Traffic Safety Administration (NHTSA) was investigating reports that some trucks would stall and be unable to start again. This was believed to be related to a defective high-pressure fuel pump.

A Stellantis statement said the company reviewed warranty data and "discovered the components are subject to inadvertent wear that may contaminate their mechanisms with metal shavings. If this occurs, it may cause the vehicles to stall or prevent them from starting." Stellantis emphasized it is "unaware" of accidents or injuries as a result of the issue and that it started its own internal investigation before NHTSA did.

The NHTSA document said the stalling reportedly occurred when trucks were moving at more than 25 mph and it "resulted in permanent disablement of the vehicle."There were 22 reports of the problem as of the date the document was published on October 14, 2021. Stellantis's recall report says a malfunction indicator lamp may light up to indicate the problem is occurring, or there may be "a fuel leak, abnormal engine noise, or a change in drive quality." Vehicles involved in the recall are Ram 2500, 3500, 4500, and 5500 trucks built between October 11, 2018, and November 13, 2020.
