Certain 2014-2020 Jeep Grand Cherokee and 2014-2019 Ram 1500 vehicles equipped with 3.0L diesel engines, could experience high-pressure fuel pump failure. If the pump fails while the vehicle is being operated, drivers will experience an unexpected loss of engine power and an increased chance of an accident.
In February 2022, Fiat Chrysler Automobiles (FCA) Technical Safety and Regulatory Compliance (TSRC) organization started an investigation into Jeep Grand Cherokee and Ram 1500 trucks, after receiving field reports that the fuel pump in some vehicles were prematurely failing. An investigation of the stall patterns and vehicle histories showed that the affected trucks were equipped with Bosch CP4.2 high-pressure fuel pumps (HPFP).
According to the defect report, a failure inside the fuel pump could introduce internal debris that could build up and cause fuel starvation. Fuel starvation may result in an unexpected loss of motive power, which could contribute to a vehicle to crash. The suspect period began on June 12, 2013, when 3.0L Diesel engines with suspect HPFPs were introduced into vehicle production, and ended on December 13, 2019, when 3.0L Diesel engines with suspect HPFPs were no longer used in vehicle production.
Warning signs that your vehicle may be experiencing this problem include: Drivers may notice a Malfunction Indicator Lamp, a service Electronic Throttle Control indicator, a fuel leak at the HPFP, or excessive noise from the HPFP.
FCA US is aware of 215 customer assistance records, 1,061 warranty claims, and three field reports that could be related to this issue.
Owners receiving notices will be asked to return to their dealers to have the HPFP replaced. Dealers will also inspect the entire fuel system and replace components as necessary. FCA’s number for this recall is Z46 and the NHTSA campaign number is 22V-406.
