New Safety Recall Advanced Communication – 01A

FCA US LLC (FCA US) has announced a safety recall on certain 2022 through 2023 Model Year (DT) Ram 1500 Pickups and 2021 through 2023 Model Year (JL) Jeep® Wrangler and (JT) Gladiator vehicles equipped with a 3.0L engines.



Some of the above vehicles may have been built with a High Pressure Fuel Pump (“HPFP”) that could fail prematurely.
A HPFP failure may introduce internally failed component debris into the fuel system potentially causing fuel starvation. Fuel starvation may result in an unexpected loss of motive power, which can cause a vehicle crash without prior warning.



FCA US will conduct a voluntary safety recall to replace the HPFP, and inspect and, if necessary, replace additional fuel system components. The remedy for this condition is not currently available. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in 3rd Quarter of 2023.

  • From February 2022, through March 2023, FCA US TSRC conducted an analysis of stall patterns and vehicle history, determined that the affected vehicles were equipped with the Bosch CP4.2 high pressure fuel pump, and determined that the high pressure fuel pump was the origin of the stalls.
  • As of March 30, 2023, FCA US is aware of seven customer assistance records, 126 warranty claims, eight field reports, and three other service records potentially related to this issue for all markets with dates of receipt ranging from April 14, 2022 to March 9, 2023.
