Fuel System, Diesel:Delivery:Fuel Pump

Chrysler (FCA US, LLC) is recalling certain 2014-2020 Jeep Grand Cherokee, and 2014-2019 Ram 1500 vehicles equipped with 3.0L diesel engines. A high pressure fuel pump (HPFP) failure may introduce internal debris into the fuel system, potentially resulting in fuel starvation.

Risk and remedy

Risk: Fuel starvation may result in an unexpected loss of drive power, increasing the risk of a crash.
Remedy: Dealers will replace the HPFP, and inspect and replace, if necessary, additional fuel system components, free of charge. Interim notification letters informing owners of the safety risk were mailed July 21, 2022. Owner notification letters for were mailed for Jeep Grand Cherokee owners starting January 11, 2024. Owner notification letters for Ram 1500 owners were mailed March 7, 2024. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLS's number for this recall is Z46.

NHTSA summary

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation

Should you keep driving it?

This page can't tell you that. 0 of 40 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
