NHTSA Calls For Investigation Of Ram Diesel Pumps

The NHTSA has asked Stellanstis to investigate a possible fuel pump failure in some RAM models. The NHTSA-issued investigation has been ongoing since 2019 and if it is raised to a recall, it could affect more than 600,000 trucks.

NHTSA Calls For Investigation Of Ram Diesel Pumps

The National Highway Traffic Safety Administration is working with Stellantis to investigate potential high-pressure fuel pump failures on its 2018-2020 Ram trucks with the 6.7-liter Cummins diesel engine. According to an NHTSA announcement on October 14, there have been 22 reports of pump failures.

Importance of the high pressure fuel pump

A diesel engine literally lives or dies by its high pressure fuel pump, thanks to the massive pressures required to atomize diesel fuel enough for efficient combustion.

faulty or bad pump can cause a stall or no-start condition . The NHTSA document states that so far all failures have occurred at speeds in excess of 25 mph.

The failure could represent a recall

This investigation has yet to become a recall, nor is it clear how many vehicles would be affected if it soars that far ( NHTSA estimates up to 604,651 ), but only time will tell for sure.
